Hey, folks-

My first post here; sorry if I overdo or underdo any of the details here. I have an HP
Pavilion 735n running XP Home. Things have seemed a bit garbaged up lately, so I
decided to do a complete reinstall. I decided it was also a good time to
change the 4-year old CMOS battery (a plain CR2032). Well, I changed it and started the
reinstall; on the second disc (out of 6) the computer just shut down. No beeps, no warning;
just turned off and couldn't be turned back on until I unplugged it and started again. Tried
to install again, and the same thing happened, over and over again. I put the original
battery back in to see if I could at least finish an install, but that didn't work. Neither did
doing it without any battery at all, which one person says SHOULD rule out it having
anything to do with the battery. The hard drive was already formatted by the first time it
happened so there's no way of solving the problem from within XP. I also don't know
what the original bios settings were, so all I could do was load the defaults, which I’m told
should work. Is it a clue that every time it shuts off, the time and date in the Bios default
back to January 1st, 2001, even with the new battery? I know the shutting down could be
due to a lot of things that you can’t diagnose from there, but my main questions are these:
Do any of you have any personal experience with a computer that never had any
shutting-down problems before, suddenly starting to do so afte... Read more

A:Changed CMOS battery; computer keeps shutting down

First of all, check and make sure you didn't put the battery in upside down. The + mark on the battery should be facing UP.

Follow the instructions here for reconfiguring BIOS and see if you still have the problem.

Its a packard bell laptop, and the system started to freeze for no reason. No viruses. Now, I can usually only move the mouse pointer-if it lets me start windows at all (xp). As of tonight, the system wouldnt let me even pass the startup screen, it kept asking for a non existent system password to continue! The system bios clock seems to reset itself too, so I believe the whole problem to be related to the cmos battery.

My main question is, how much should I roughly be expected to pay for a cmos battery and installation from a general pc repair store? The laptop is out of warranty, so I dont really want to be spending £30+ just for Packard to find and install one either. The reason I need someone else to do it is because this particular packard system has the most awkward setup, and therefore access to the battery is next to impossible..

as you can see from my (slightly blurry) photo-
http://img600.imageshack.us/img600/2219/cmoslocation.png

there are only 3 panels on the back of the machine that you can remove- 1 hard drive, 2 ram, and 3 wifi card (I think!).. the cmos battery (the circle!) is to the right of one of the panels, under the casing. I have tried removing the entire casing, all screws and connections, and even from the front, trying to get to it by removing the keyboard, but it proved impossible to me, so Id rather get someone else to do it. No doubt the difficulty is on purpose so that you would always send it to packard for repair, and for a high price, bu... Read more

Otherwise to get the best deal I would phone a few small local computer shops and compare their prices with big chains like PC World.

Hello, I noticed about six months ago a memory problem was showing in my mini view on my xps 420. I removed the boards and reseated them and the error went away until now. I ran the diagnostics and followed the error code. It said my cmos battery was bad. I changed the battery and now it will not boot. I ran the repair cd with no luck. Can someone offer some suggestions ? Thanks--- Larry D

A:Computer will not boot after cmos battery.

Remove the CMOS battery.
Unplug the power cord.
Press and hold the power button for 10 seconds to fully drain all residual power.
Put the CMOS battery back in, make sure you put it in correctly.
Plug in the power cord.
Power up.

You should get a CMOS configuration error message. Press F2 to go into Setup, load defaults, set date and time and boot options then see if it will boot.

I just changed my CMOS battery and now my computer screen is jumping all over the place, like the fine tuner is messed up! I wore a static wrap, rubber gloves and I turned off the computer. I even reset my date & Time, and checked my monitor cables to see if they were lose, but their OK. Any ideas on why my computer screen is jumping around? I even checked the battery to see if it was good, and cleaned the battery, it's OK! Please help!

A:Changed Cmos Battery

When you take out the motherboard battery for a length of time, the BIOS returns to default settings.
First, did you reset the date and time in the BIOS. Does your computer have onboard video or a video card? did it used to have onboard video, but you added a video card?
Also check you refresh rate in the monitor's properties

When I had to change the CMOS battery on my older Intel Pentium w/MMX for the first time a couple of months ago, I found that it is mounted vertically. This means that instead of using gravity to hold it securely in place as would be the case if it were horizontal, it relies solely on a flimsy little "arm" to hold it in the correct position.

Unfortunately this little "arm" is pretty puny and, although I replaced the battery as carefully as I could, the arm would no longer hold the battery in place. Since the arm is too flimsy to mess with, I was forced to fold a small piece of aluminum foil and wedge it between the battery and the arm.

That worked for a while but although the computer is located where it won't be bumped, within a few days the battery had become unseated (though not visibly) and my computer was only working sporatically.

As a last resort I turned the computer on its side so that the battery would rest horizontally, and it has worked beautifully ever since.

However, I am now without the use of my CD-ROM drive because, of course, now IT is vertical and the CD's just fall out no matter what I do.

As I said, it's an older computer but there's no way I can afford a newer one on my tiny income. Is it possible for a relative greenhorn like myself (in the computer hardware department anyway) to change the mounting for the CMOS battery from vertical-mount to horizontal-mount?

the next few boots were dodgy and it only booted up every second or third attempt. if it didnt boot up it wouldnt boot and just went beep (long beeps and repeated -in no code) this worked for 4 boots before it never booted again.
it just beeped.
until i moved the jumpers on the 3 pins from the two pins closest to the battery position to the furthest two. and turned the pc on. it didnt beep. the monitor didnt respond and but it seemed to be turned on (the cpu fan was going and a green LED on the mobo was on). i then turned the power off. and stuck the jumper back on the original pins and turned it back on hoping the BIOS would be reset but the beeping sequence continued and nothing seemed to start.

A:HELP! Computer won't boot! BIOS? Reset it. CMOS Battery? In and Outed it. HELP!

The Athlon XP 2600 that runs at 1917MHz runs on an FSB of 166MHz and has a clock multiplier of 11.5 (166 X 11.5 = 1909Mhz).

So if you have a system bus setting of 200MHz and the clock multiplier is set a 11.5, you were running it at 2300MHz, which is seriously overclocking it.

The processor might not have been up to that much overclocking and died.

Find out what BIOS settings do before you change them!

Hey guys and girls,

Computer is:
Dell 8400
Bios V 1.10 A09
Win XP Pro SP3

After receiving "Alert! System battery voltage is low." I was told to change out the CMOS battery (the coin battery). I replaced the battery, entered the CMOS setup, reset to factory defaults, corrected settings, cleared the event log, and set the time and date. Then saved and exit.

Haven't had any problems with the computer until now.

Here is the problem:

Computer restarts Dell screen loads, then black dos screen for a sec, then it tells me that Win XP couldn't start. It asks me to start in: Safe Mode, Safe Mode with Networking, Safe Mode with Prompt, Last Known Settings, Windows Normally. I used everyone and Win XP comes up for a second, than Restarts back to the Dell screen and repeats all over again.

I did a diagnostic on both hard drives and both Passed. Next, I put the XP in to boot from CD. It goes through the first stage, than it says windows setup loading. BLUE SCREEN of DEATH.
The code says:
0x0000007B (0xF78D663C, 0xC0000034, 0x00000000, 0x00000000)

I figured the next thing is to have it checked out. But I was curious to see if anyone here could help.

Talked to Dell already, they couldn't help.

Thanks for your time.

Hello everyone, apologies for the tl;dr rant. I?ve stepped into a depressingly common problem with these EliteDesks, but no solutions have been forthcoming, so let's see if we can reach one. The CMOS battery in one of our dc7800 machines died, so it was replaced. After going into BIOS and fixing the settings, now the PC refuses to boot at all; it freezes with this error:  2215-EIT failure. VA boot record read failure.
  Ensure drive with VA image in installed.So begins my journey into the hateful world of HP/Intel desktop security. The first suggestion is to turn off Intel VT in BIOS. I do that. Then the PC freezes with this error:  2223-EIT failure. VT must be enabled to launch VA.
  Enter F10 Setup and enable Intel Virtualization Technology.I turn VT back on, and it cycles back to the first error in a ludicrous tail-chasing exercise. Next, it is suggested by the HP manual that I enter the MEPx menu (ctrl-p) and disable those features. However, I can't enter MEPx because the machine keeps freezing as per the errors above. The only way I can get in is to remove all disks and boot devices. I do so; finally, I get into MEPx and attempt to disable VA in the AMT config (p.5)? BUT THERE IS NO VA CONFIGURATION OPTION! So I simply disable ME entirely. Problem solved, right? Wrong. Now at least the machine starts without those errors. But as soon as I plug the HDD back in, gue... Read more

Hello Friends... My PC was giving, system battery low, message so i replaced cmos battery but it didn't boot until i set bios to its default values so finally i was able to boot but my hard drive is making strange noises now so even if right click and press refresh in the dialogue box, my hard drive produces sound and a light appears on the front of casing where i think Hard Drive is located.... Some kind soul told me to change my bios to its previous settings but i am wondering how do i do that?? is this strange behavior of my hard drive related to Cmos battery change or alteration of bios settings?? I just realized that i have made another thread probably too soon but i thought i should have a different one for a different question but still my apologies to Admin... Thank You...

A:Cmos battery changed but hard drive is producing strange noises...

I dont think the 2 are related. your bios has no effect on your harddrive once the system has posted. once windows starts loading its windows drivers that run the show.

I beleive your hard drive might be on its last legs. you could run some hard drive utilities to test for bad sectors ect, but in the mean time id grab yourself a spare harddrive and back everything up just in case

Also i set my RAM at 1000 just like my procesors FSB and at timmings of 5-5-5-9 and either default voltage or 2.2 volts (can't remeber anyway none are dangerous)

In my BOIS, in the overclocking section, i had my memory and CPU unlinked but just now, i set it to linked and entered the FSB back to the stock 800.

Next, my daughter stuck her flash drive in my system kid didn't even know where to stick it, should have stuck it in her ear first because she had no clue as to what she was doing. don't they study first, nope. The next day my system would not boot.

In order to get back into the system I had to turn off the system press esc to get into Load Boot which brings me to a screen where I select the hard drive. It then brings up screen Default Bios settings have been loaded due to BIOS update or checksum issue press f10 to enter setup otherwise allow the PC to continue. I let it continue and windows comes up but it takes about 10 minutes. I'm a little stuck here, do I have a major problem or something that can be fixed. I was reading and could use some help here I was reading about the ROM BIOS don't know what else to do at this point. I ran Hardware Diagnostic Tool and everything passed except the Smarshort self test took about 13 min. put it passed. I also ran a Sysem memory test and everything passed. Help me please!

The system will not be able to hold BIOS settings unless the battery is in.

You mentioned 2 things that happened to the computer but not what the results were. Where did she put the drive? Did the system work after you tried the wrong RAM? Did either of these things cause damage, and if so, what damage? Did you check all your connections inside after changing the RAM sticks (things get loosened very often)?

I apologize for the length of my post, but I have gone thru several steps in trying to solve my problem.
I turned my Win-7 PC on and got the error message "CMOS/GPNU checksum bad".

Research suggested one cause might be the CMOS battery (#2032), which I replaced. I entered BIOS and everything looked good except for the date/time, which I reset. I then rebooted and got the error message "invalid partition table". At that point I inserted my Win-7 installation DVD to try and repair my installation. Unfortunately, no OS was found on the hard drive. So I selected the option to re-image (using a fairly recent system image stored on an external drive). After about an hour, the process was finished and I got the message that the restore was successful. A system restart was then required, but it was not successful....I once again got the error message "invalid partition table".

I also got the message that the reason that the startup repair was not successful was because 'no OS found on disk".

Any help/advice would be appreciated. At last resort I could try a complete reinstall of Win-7 but I would probably lose a lot of data that I had been backing up via the system image.

A:Can't boot or repair Win 7 after replacing CMOS battery

Hi Durango,

I would try the following:

Turn off the laptop/desktop
Unplug the External USB HDD (and all other USB devices)
Make sure ALL media bays (SD Card reader and DVD drive) are empty
Go into the BIOS config on boot up, and configure the boot sequence to leave off everything except Internal HDD, and CD/DVD (turn off the USB and secondary (if any exists) HDD from the boot sequence)
Reboot - and hopefully windows should resume without any error message.

In the last year I have had a slew of computer issues.The most prominent however is a blue screen. After the bsod crash my computer doesn't boot. I can hear it attempt to start up then quit, and it repeats that until I force turn it off. Unfortunately the little speaker on my motherboard no longer beeps so I can't tell you what beeps it gives. If I poke the CMOS battery a little bit the computer starts up again and keeps acts like nothing is wrong until it gets another bsod. The battery seems to not be held in place well, it wobbles quite a bit. And in the last few days the bsod has only been occurring more and more often.

There have also been some strange visual problems with my primary monitor. When the log in screen pops up it switches to a message saying something like "input unsupported" and I simply restart the monitor. In the last few days the bsod has become more common and right before the crash I get lines or streaks of randomly colored pixels on the display. And very rarely the monitor flashes that old black and white static you might see on a TV for a few moments. This might not have anything to do with my bsod problem though, just putting the information here in case.

It sounds like they put the wrong CMOS battery in your machine. I'd check the MB manufacturer for the right one and replace it. Also a lot of what you've mentioned sounds like a GPU issue. Please make sure it's seated tightly and drivers are up to date.

To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Hi:

My CMOS battery is dead and I've yet to open and replace. I keep the time set correctly manually. Would this cause the computer to operate as if in slow motion?

I've run several CPU speed checks and all report over double the 1.73 GHz, sometimes as high as 2.8 GHz.

Any and all advice or comments will be appreciated.

Thanks, Robert

Hi,

A friend of mine has a computer that upon booting, was giving her the message that the system battery was low. Plus, her clock and date was wrong. So, she checked the number on the old battery, but left it in, went and bought a new battery of the same kind, and exchanged them. As soon as she did that, the computer will now no longer boot at all.

Now all she gets to is the black screen with white writing that says the name of the components, etc. It says it's a Dell Workstation 360 series, mentions the BIOS is version A04, finds the primary SATA drive, etc. then it says at the bottom to strike F1 to continue or *something else, I can't remember* to proceed to setup. She hits F1, and all it does is give her a second set of "strike F1 to continue......" won't do anything else.

All this she told me over the phone, but before I have her try anything else, like get into safe mode, or something, I was just wondering if changing that battery could have done anything to have caused this. I don't THINK so, I've never heard of it causing a problem like this, but I just wanted to be sure.

Also, is anyone familiar with Dells and what key one taps upon reboot to get into safe mode?

Thanks!

I have two identical Dell XPS 8700 for my kids. I got them around May 2015.  They use them mainly for steam games and Office 2016.Both running the Windows 10 AU.Today on one of them, by son said a message popped up and asked to stop a service and he clicked yes. Then all there was, was a gray screen and mouse pointer. He came and got me. The pointer would move but nothing else responded. So I did a power shut down. On reboot, the machine took around 40 seconds from seeing the dell logo to the sign on screen. This seemed very long. So I rebooted the other machine to see how long it takes, and it was only 3 seconds from the dell logo to the sign on screen. I do not know if the long boot time has been going on or just started with this issue.I ran sfc /scannow and it said no issues.I remember in September 2015 ( a year ago) I had an issue with this machine where on power on, all I would get is the spinning dots at the Dell logo and it would not boot into windows. I even let it sit there for 24 hours and just spinning dots. I even tried new install of windows where the machine would let me install new windows, but after updates, the same thing happened with the spinning dots.After a tons of troubleshooting, a dell tech recommended pulling the cmos battery. I did that and from then on it booted fine.So since the long boot time did not seem right, I pulled the cmos battery again. waited 30 seconds, put it back in and booted into bios, change the clock (not sure if I had t...

Problem developed after my kids were using the floppy drive to save a document but not sure if this was the cause. Now it won't post so I cant get into bios or os at all. Monitor flickers in sleep mode and both CD drives light up and start spinning with no discs in.

I've had touble in the past tring to clear cmos on this mobo which is a Matsonic MS8137C+SI. Go through the shorting process as advised but does not clear cmos.

Any other ideas on how to clear the cmos as I think this will clear the problem by resetting to defaults.

I've also noticed that the floppy drive does not light up when I switch on.

My full system is: AMD XP 2400 running at 100 fsb (Has run at 133 but switching is tricky)
Matsonic MS8137C+ Socket A Mobo

I've stripped the whole system down including reseating the Processor and tried a reboot with only basics connected but still cant get past a flashing monitor so cant even get into safemode or bios to fix. I've also tried another graphics card.

This is not a serious issue but it is annoying me.

Last week my A7N8X motherboard started reported a CMOS checksum error, so I replaced the CR2032 battery.

The checksum error is gone, but now whenever I switch the computer on at the mains it boots up automatically, without me pressing the button on the tower.

I have checked that none of the 'wake up' settings are enabled. What else could be causing it to boot automatically?

Hello and welcome to Techspot.

Check the connectors from your power switch to your mobo. maybe they`ve become loose or something.

The only other thing I can think of, is your power switch is faulty.

Hello there,
 
It seems like you did not perform a clean installation of Windows and that's why your system is acting up. 
 
Follow the steps below to install a new copy of Windows:
 
1. To format your hard disk during Windows 7 installation you will need to start or boot your computer using the Windows 7 installation disc or USB flash drive. Insert your Windows 7 disc in your CD/DVD drive. Please note: will need to restart or turn on your system with the disc in the drive. 
2. After turning on your system with the CD in the drive go ahead and press any key when prompted during your computer post routine and then follow the instructions presented on screen. If you don’t see this go back to step 1 to setup your BIOS to boot from CD or USB flash drive depending on your installation media.
3. On the Install Windows page simply enter your preferences and click next.
 
4. Accept the Windows license agreement.
 
5. On the “Which type of installation do you want” page go ahead and choose the “Custom” option.
 
6. Select Drive options (advanced) on the “Where do you want to install Windows” page.

Hi my name is Viviana...

I had set my password in BIOS awhile back. And I had forgotten it. I needed to format my hard drive because of an intense accumulation of viruses. I tried everything... the default password for phoenix... nothing worked. I even removed the battery on the motherboard. Still nothing. I shut the computer off but leaving it connected thru just the wires on back... Then I googled for directions on what to do next. I played around with the wires but not really touching or moving much... then I downloaded the manual for micro star msi 7211 from the manufacturer. It told me to look close to the battery. And don't quote me exactly I'm on my android phone.... it told me to lift the plastic like piece from the 3 jumpers I think, I'm not sure of the name. But they are 3 little spikes... so I did that and went to turn it on. No response. Nothing would turn on. I really hope maybe I did something wrong any my motherboard IS NOT FRIED. Can anyone please tell me Wats goin on here
 

A:Computer wont turn on after attempt to clear cmos

First of all what you did was pull the jumper that is used to reset the BIOS password so it sounds like you have done the right thing.

Around the jump (little plastic piece) there should be printed on the board PASS RESET or BIOS RESET or something of the like. Alot of times you have to pull the jumper, cycle the power, then put the jumper back.

I have just replaced my CMOS/BIOS battery today, as , I have faced some critical problem regarding regular BIOS date/time reset after system shutdown. But I want to know how do i recognize, that my new batter is totally ok or functional.

Battery Meter gadget shows that "battery Not charging"
Is it a gadget problem?

Is there any method available so that I can track that my new installed CMOS battery in PC is working fine?

Please help me.

A:Battery Meter shows CMOS battery not charging

The battery you have replaced is solely there to maintain the clock and other BIOS settings (if you have changed them from their defaults). It will not prevent you from booting your system if it is dead/missing; all it means is that you will have to enter the BIOS each time and make the correct settings and time. This battery is not rechargeable.

Do you still have to enter the correct time, or is the BIOS maintaining this now you've changed the battery?

A:Question about RTC Battery (CMOS Battery) and System Errors

CWILLIAM83 Hello;Allow me to welcome you to the HP forums!The answer is actually -- yes and no. A weak or dead CMOS battery will prevent the BIOS settings from being saved when you power off the PC. If the default settings work OK with your hardware, then the only thing you would notice is that the clock resets. But, if you customized your settings to see the hard drive, then the default settings might not see it. After you replace the battery, you would have to go through configuring the settings-- again.Good Luck

Hi guys.

Been having BSODs almost every day for 2 months. Today the computer won't even boot to bios, even though I can hear the fans and maybe harddisk running.

Before the bootproblems i ran the following tests:

Memtest86: 7 passes with no errors
Memtest (hcidesign.com) inside windows 7: Showed errors right away
CPU and GPU temperature measurement: Normal temps

The BSOD i got before the system stopped working completely are attached.

I would really appreciate it if someone took the time to help me, been trying to solve this problem for weeks on my own.

I think it might be the RAM, but it could also be the motherboard, cpu, harddrives etc right?

A:Lots of BSOD, now the computer wont even boot to BIOS!

If the system won't boot to the BIOS, you have a hardware problem. You'll have to fix the hardware problem BEFORE you can do anything else (all of our diagnostics rely on being able to see something in the screen).

Although I'm not a fan of the HCIDesign test, it tells us something that MemTest doesn't.
You'll have to test the individual RAM sticks one-by-one to see if you can isolate the problem stick(s).

What happens when you try to boot to the MemTest disk? Does the system work with that? If so, then there's probably not a problem with the video card. But, if it doesn't work with that, then it's time to look at the video card.
Double check all cables, then try another graphics card to see if that's the issue. If you don't have a graphics card to try with, then see about purchasing one from a place that will let you return it.

There are 34 memory dumps dated 15 Jan to 11 Mar 2011
13 different BSOD error codes
and 11 different causes blamed
This is most likely a hardware problem (as described above).

The first thing i see as it starts up is an error message about a bad CMOS checksum and then i have to change the date/time in the BIOS or it yells at me to do it. After all that it boots into windows 7. Once it is in windows no matter what i do to change the settings of what the power button does it still doesn't do anything. I can restart it fine but once i shut it down it the CMOS battery needs to be reset to get it going again.

I tried to go into the CMOS but didn't really know what to do once there.
So my question i guess is, is this something i can ignore, or should i do something about it and if so how?

I cant notice any real performance issues but don't know if I'm getting full use of my CPU.

Please help, don't want to ruin my computer.
 

A:Warning CPU has changed Enter CPU setting in CMOS

eppa.jp,

It won't be doing you any harm, it's just alerting to let you know that it's changed, from what it remembers. They'll be a way somewhere in your BIOS (or maybe on boot) to acknowledge the change, that you'll want to do at some point, just to get rid of the annoying message.

Might want to look at the book / docs that came with your Motherboard for distructions on how to 'ok' it. If the barebone PC didn't come with any, then see if you can see a sticker on the motherboard itself, and either search the net for it, or post the results back here, and we'll take a look for you.

I need to know which way the wires (2 of them total) go on my compaq armada 7770dmt. While replacing the cmos battery I got the wires mixed up when I put the plastic end on. Since the plastic piece only fits one way I know that it must matter which way the wires are attaached. The colors of the wires are red and white. I cannot find a schematic for the motherboard.

I have a 486 mother board. When I boot up into DOS I get a message saying, CMOS BATTERY LOW. How do I replace it.
 

A:CMOS Battery

Crack the case open and look for it. THe older ones on 386 and 486 motherboards were some times integrated into the BIOS so you might be out of luck. Others had a small black pack that looked like 4 AAA batteries connected together and a red/black set of wires running to the motherboard....you can still get those.

The most commonly used battery is CR2032. If you still have the P4S800-MX motherboard (from a May post), turn off your PC and remove the left side cover. The battery is a 5 cent coin size disk near your IDE drive connectors.

You can get the battery about anywhere (I saw them at the grocery store last week).

Hi everyone,
I have an NEC Versa 4230, with win95,133mhz notebook. When I turn it on it tells me the system battery is dead, and to replace it. Thing is I don't know where it is at or where to get one. Do places like circuit city sell them. Any help would be greatly appreciated. Thanks , JOE

Well I looked it up a NEC and the bad news is they say must be replaced by certified NEC site.

Either they just want to charge the money or it's not easy to do.

Could be soldered to motherboard instead of clip type which is a major pain.

Sorry, don't have any better info for you

my system clock slows down if I shutdown system. is it b'coz of my cmos battery is being low?
How do I find whether my system has a cmos battery?How will I know what type, who is the maker etc? How do I know whether it is getting low?can u suggest some softwares that check it? I am rather naive with hardware and has opened the motherboard only to clean it.My PC is 4 yrs old. Is there any problem if I don't change it other than system clock becoming low.If it is necessary to change cmos battery how much does it cost in rupees?
 

A:is cmos battery getting low

When you open your case you will see the CMOS battery on the motherboard. It resembles a watch battery. It is flat and round and looks almost a like a button. Just pop the battery out and off to Radio Shack or any other place that sells batteries for watches and other electronic devices. The first sign of a faulty CMOS battery is the system clock changing and not displaying or retaining the correct time.

Well im about to take out my CMOS battery and need to know if it will reset everything that ive downloaded or just my bioes settings will it reset my password for the admin?

If i remove the CMOS battery will it clear everything like a reformat?

A:CMOS battery

Clearing the CMOS will only clear your BIOS settings like Boot order, CPU settings, stuff like that. It will not format anything, nor will it reset any passwords. Even if it is a bios password, most manufacturers make sure that it is a little harder then that to clear the password. If you have forgotten your password for windows it will not effect that but there are ways to do that.

Hi guys and gals, quick question. I have a HP Pavilion G7 laptop that was giving me some cmos error messages so after some ridiculously rigorous searching, I found the battery. My question is, does the numbers on the battery mean anything? Meaning, ive found HP pavilion Gy batteries on line for sale but the numbers on the sticker on the rubber housing dont seem to match. Im wondering if that is just the warehouses part ID. This one says, "1126. 12." If anyone is familiar with these please let me know. Thanks

I just tried to install a new battery and broke the spring clip part of the socket. Is there a remedy? TIA, Brian
 

A:Cmos Battery

Unfortunately there really is no easy repair for this. It would require desoldering the old battery socket and soldering a new one in. While this is not rocket science, it does take great care and some skill to do. A minor slip or laving the soldering iron in place too long can do some real damage to a motherboard. It is best left to a technicial with the proper equipment and skill to do. I would consult your local computer shop about this repair. And it may take a referal to someone else.

Question : Does anyone know if a "faulty" CMOS battery (the CR2032 type) can stop a laptop working?

This is the sequence of events: -

1. Booted laptop from standby as normal.
2. Logged in
3. Everything working as usual for about 30 minutes

Then I stopped working on the laptop to talk to someone. While we were talking I noticed the laptop screen suddenly went blank. From that moment forth the little darling has been as dead as the Christmas turkey.

My experience with CMOS batteries that are about to go play a harp is that they indicate this by displaying the wrong date and time. Even then it can take days or even weeks before the battery finally gives up.

I used my last CR2032 a few days ago, so before I go trundling down to the shops I would be grateful if anyone could tell me if a "deceased" CR2032 can make a laptop suddenly die.

I haven't seen that before.

Welcome to TechSpot! Hope you'll love this place as much as I do.

If you haven't already done it, then open up your case and look around on the motherboard for a shiny round thing that's about 1.5cm in diameter, pull it out off it's socket and there you go.
It should be near your PCI-ports or near your CMOS-jumper.

unplug the PC, even the power cord at the back
ground yourself (ie touch metal, discharge static)
open the case and point a flashlight at it
carefully pry it out, usually a clip you GENTLY pull back to allow the battery to pop out
(you do NOT want to break the clip off)

any radio shack or pc store will have them

Hi guys,

My computer just started having this problem since Christmas. I've had this mobo since 2007, and this is the first time when I switch on the comp it gives me thsese messages randomly:

"CMOS battery low"
"Error loading drive A"
"Error boot sequence"
"Press F2 to continue or F1 to enter setup"

I went into the BIOS and it is always set at factory default settings, even when I attempt to change them to the previous settings I had. It gives me a message that says that because the CMOS battery is low, my date and time and other BIOS settings will be reset to default, then gives me the error boot sequence msg, and still continues to load windows, and desktop is messed up a bit, but otherwise "normal" except for the sys tray that's missing icons...

I have never really encountered this situation before, but the solution seems straightforward: replace the CMOS battery, only that I don't know where to find it! I've tried tigerdirect.ca, newegg.ca and even a local computer store, but they don't have it on their website.

My mobo is an OEM (Lenovo 3000 J205-9686) ASUS M2A-VM with a 690G chipset & AM2 socket. What additional details do you need to know what CMOS battery I need to buy, and if possible, any websites I can go to in order to find it (preferrably Canadian due to shipping costs, but I don't mind US).

Also, my OS is win 7 RC (although that might not be relevant)... Read more

Question. In the motherboard manual it says to use a flat screwdriver to pry the cmos battery to change it. Well, I was doing that and the cmos battery sparked. First question is, what tool do you guys recemend. So, the motherboard cmos holder doesn't break, and so it doesn't spark again?
Second, is a spark from a 3v cmos battery harmfull to me, if it came up the screwdriver? I don't even know if it did, but I was a little freaked out by the spark, because it didn't say anything about it possibly happening. Of course, the pc was not plugged into a wall or anything. It, was just the battery itself.

Thanks everyone
 

A:Cmos 3v battery

Probably ran into a residual charge on the power supply.
Want to make sure not to short the 2 battery contacts or
short it to any metal on the case.
You can usually discharge a lot of that by pressing the power
button with the power supply turned off or unplugged.
The battery holder should have metal clips on one side.
Press on the opposite side of the battery to push it against the clips
then lift it out.
The clips are spring loaded to hold it in.

I recently had a major computer crash following a lightning storm and a lengthy power failure. I feared the worst and called out a tech. It turned out that the CMOS battery was dead and when the power had failed, the CMOS settings were lost.

The tech said that under normal circumstances, as long as the computer was connect to the power supply, the settings were retained but when the power failed, the settings went.

So if I just use system shut down on the computer at night, there is obviously power still getting to the computer. However I assume if if I actually turn off the computer on/off switch then there will be no power getting through and the CMOS battery takes over.

If I do that every time I turn off the compueter I assume that the CMOS battery will not last as long.

Am I correct?

Does it do this on every boot up? Have you tried going F2, after your in the bios hit F10 (should prompt you to SAVE, if not, then exit and save) If it continues to do this then yes, you will need to replace the CMOS battery and hope that it is just the battery and not where it sits.

It's time to change the battery (first time for a machine I bought in 2004 - not a bad run). I can't get the old one out....any suggestions?

On side should have a metal contact.
You need to carefully pry it toward that contact as it is spring loaded,
then lift from the other side.
Should pop right out.
Be careful you don't want to break the socket.
Some older cmos batteries were soldered on,but I haven't
seen that since around 2000.

CMOS battery

What happens and what is the danger to your computer if the CMOS battery dies?
 

A:CMOS battery

The CMOS battery is a very low powered device, just like a little watch battery.

So don't stress, it ain't gonna kill you.

However, its needed to keep data in the CMOS. The CMOS tells the computer what processor is installed (although many computers have jumpers set to tell it this), what drives you have (diskette, hard disk, CD-ROM, and others, and importantly your hard drive's geometry), how much memory is installed, and other important data that your computer needs to know in order to run correctly....

I imagine what would happen if it completely ran out would be that the CMOS would have to be re-written to manually in your BIOS program every time the machine was powered on for anything like normal operating to occur. Certainly you would loose the time settings and would have to redirect the BIOS to redetect the hard drives everytime you powered on.

You can replace a CMOS battery quickly and easily. They are very cheap and just clip out and in to the motherboard. It resembles a small silver disc about the size of a coin.

This is assuming that your computer is not totally ancient (like a 8088, 8086, maybe 286 or something) where the CMOS battery was sometimes not removable. If this is the case then get a new computer you sad man..... Otherwise, it will cost you nothing to replace and if you are not sure of yourself a computer store will do it in about 1 minute.

Hi,

Ive been working on this old computer and it had a bad CMOS battery. It was the kind where you put AA's into it and then it plugged into the motherboard. I replaced it, but now the hard drive settings are all screwed up. I went into the Bios Program to set everything. But none of the options matches the hard drive. I know for a fact that this computer worked before the cmos battery went dead. The options in BIOS you can only set to
Type 1, Type2, etc. There is no "USER" setting where you can just put in the numbers of heads/cylinders/sectors. What should i do?
 

A:CMOS battery

If you have no user or auto settings try setting the bios to type one. Hopefully the drive was originally using a drive overlay and will boot ok with this setting.

I do not see a Cmos battery obviously its there somewhere, If it doesn't look like a large watch battery what else does it look like, I see nothing that can be popped off and replaced.
 

A:Cmos Battery??

Some older motherboards had a barrel shaped, blue backup battery soldered to the motherboard. That was common with 486 systems. In order to replace it, you were required to attach an external battery to a specific connector on the motherboard and set a jumper (maybe) to disable the original battery.
Another possibility is a CMOS ram chip with the battery built into it. Those usually were a large black chip plugged into a socket on the motherboard with "DALLAS SEMICONDUCTOR" printed on it.

I Have an old 166 Pentiun computer with a i430vx mainboard. My problem is that the CMOS battery is dying and from what I could find on the net, it is enclosed in a discontinued Houston Tech HT12888A RTC chip. Some of the info on the internet says that you can open the chip and change the battery though it may be soldered in place and other sources say to replace the motherboard. Also will an add in card containing a clock also power the CMOS. I leave the computer on all the time and it runs fine but when I shut it down and reboot I lose time and have started getting a checksum error/CMOS battery failed message. I have another computer and would like to give this to my son and would hate to scrap a good machine for a $3.00 battery. Any info on this problem would be greatly appriciated.
 

A:CMOS Battery

Well I could understand not wanting to scrap the system due to a battery. There are several options you could look in to. 1. you could purchase a new mother board( for under $100) install it and actually have expansion room for later, or 2. You could scrap the system and keep it to use its parts as test parts or replacement parts for another computer. If it was me that faced this problem I'd look at a new motherboard first maybe you could even find a good used one.
