My new ProBook 4540s will not turn on

Q: My new ProBook 4540s will not turn on

I have a new ProBook 4540s notebook that I shut down over the weekend. I am not sure if I put it into hibernate, sleep, or what as I am still getting use to it. When I tried to turn it on (not plugged in) I got nothing. So I plugged in the power cord and hit the power button again. All it did was the LED above the cord plug blinked about 8 times and nothing else. I let it "charge" overnight and tried again in the morning. Nothing but a blinking LED. I Googled the problem and it said to take the battery out, unplug, and hold the power button down for 20 seconds. I plugged it back in but left the battery out, and still the same thing - flashing LED. HELP! Thanks.

Hey SBProBook,Do any other LEDs blink? Take a look at this document and let us know if you see any matches to these patterns:http://support.hp.com/us-en/document/c01443366

Attempted to up-date to Windows 10. Couldn't do it. Microsoft (MS) Tech tried to do it and couldn't do it. It seems there are some security tools that must be removed as they are incompatable with Windows 10. MS tried to remove and couldn't do it. He said they were on the mother board and when he tried to remove them they just kept coming back so once again he couldn't do it. He said contact HP and they could do it. Unable to find anybody at HP that can do it. As you can see nobody can do it so I guess it just cannot be done. That is unless some fine person out there has discovered a way to do it. If thats the case please tell me ho wo do it.

Hello! My ProBook 4540s was working fine until a half hour ago, when I unplugged it to move it and then attempted to plug it back in, and it stopped charging.  When plugging in the power cord (that came with the ProBook when I bought it around 18 months ago), the light above the power jack (and no other lights) flashes white 9 times. I've tried following this fix I found on Google: 1. Turn off the notebook2. remove the battery3. remove the charging adapter4. press + hold the power button for 40 seconds5. insert the charging adaptor only6. press the power button and it supposedly continues but I get stuck at this point, because even plugged in, my ProBook won't start up without the battery in also. Is this a know problem/is there a fix for this?

HiI tried to update to W10 and failed with OXC 1900200 which suggests a compatibility issue. It is unclear on the HP website if this model supports W10 -  HP has not tested your PC model for upgrade to Windows 10.If your Windows 7 or 8 PC was manufactured before August 2013 or is running Windows XP or Windows Vista, HP cannot confirm it can be upgraded to Windows 10.  Can anybody offer an advice if the 4540S supports the W10 upgrade and if so any advice on what may be causing the error. ThanksJohn

the touchpad of my 4540s i5 freezes after some time of working.this happens from time to time.i unstalled Synaptics TouchPad Driver and restalled but probles is the same.OS windows 8(64bit)

A:the touchpad of probook 4540s i5 freezes after sometime

Hello zamsam,

 

I understand that your touchpad will freeze.

 

Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.

This should reset the hardware in the computer.

 

As you power it back on tap the F2 key. This will load hardware diagnostics.
Run the startup test.

This will test all the hardware in the system and detect any problems.

 

If the entire test passes, turn off the computer.
As you turn it back on tap the F10 key. This will load BIOS setup utility.
Press F9 to load defaults.
Press F10 to save and exit.

When the computer boots back up, check to see if everything is working.

My laptop is running Windows 10 64-bit.

For the past few weeks my laptop has been turning off unexpectedly.

I've tried with battery only. With battery and power cable and with battery removed and only power cable.

I am using the machine normally and then screen just goes black and power offs - no restart, no hibernation, no shut down. Just instantaneously off.

It's not overheating. Could it be a fan issue?

I don't know - but it's getting quite irritating as I often have many apps open and many files open on each app and takes me 30 mins to get back to where I left off.

Dear Customer,Welcome and Thank you for posting your query on HP Support Forum It looks like you are not able to Power ON the Notebook and wanted to fix the issuePlease perform below shown steps to find out if this is a software or hardware issue:1. Remove all Peripherals and Cables, Disconnect them and try to Power ON the Unit 2. Check for LED Light Status and ensure Power Button spring action is normal 3. Swap with a known good Power Cord and Power Adapter 4. Incase no Adapter is available, Check if the Power Adapter is slightly warmNote: This will give us a hint that the Power Adapter might be fine 5. Do you know if the Notebook was in Battery or Power Adapter Mode when you used it for the last timeNote: Ensure there is no liquid spillage or Power Outage 6. Check if the AC Adapter Port is loose/broken Note: If the Notebook doesn't Power ON even with a known good Power Adapter this confirms the Hardware fault with System Board or the DC Power Circuit  Hope this helps, for any further queries reply to the post and feel free to join us again **Click the 'Thumbs Up Button' to say Thanks** Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,K N R KAlthough I am an HP employee, I am speaking for myself and not for HP

When I push the power button to my HP ProBook 4540s, it does not boot, but a few seconds later the fan turns on and the screen remains black.  If there were any error messages, I can't see them.  The only way to shut it back down is to press and hold the power button.  Then I try to boot it agian.  The computer will boot normally about 1 out of 35 or 40 attempts.  Briefly removing the battery and placing it back does not help.   I haven't made any changes to the computer.  It is about 10 months old.  Any ideas???

Since you've only had the notebook for 10 months it?s probably still under warranty. You can contact HP: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html Please let me know if any of these suggestions helped.  If not, I will try to investigate further. TobindoHP Representative

Hello everyone, So i have a problem with my HP ProBook 4320s, it won't turn on. Here's whats happening when i try to turn it on. When i have the battery in without the recharger and i try to turn it on, the orange LED light for the recharger blinks 8 times and same when i have battery in with recharger plugged in. Note, the orange LED light should stay on when recharger is plugged in and it's recharging the laptop. Now, when i have the battery out and the recharge plugged. The orange LED light doesn't even turn on at all.  Now here's what i have done. I did a hard reset, which i unplugged the recharger and removed the battery from the laptop. I then held down the power button for 60 seconds and after that i plugged in the recharger without the battery and attempted to turn on the laptop. Nothing happens and the oranged LED light doesn't turn on. I then left the recharger plugged in and this time inserted the battery. The laptop still won't turn on but the orange LED light blinks 8 times. Now i've tried this with 2 different recharger and same result above. I can confirm that the 2 recharger is working because the 2 recharger works with my other HP laptop, meaning it was able to recharge my other HP laptop.  My other HP laptop also shares the same recharger as the HP ProBook 4320s by the way.  What i've also done is, i've opened the HP ProBook laptop, took out the RAM and reinserted the RAM and tried the above and same result.

Hi, Unfortunately,  business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case. If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password. Regards, DP-K

Hello all,

I am stumped on this problem. I have a HP Probook 4540s (Win 7 x64) that has a nic that is not functioning. It acts as if the network cable is disconnected. I've taken the below troubleshooting steps.

- Checked switch port and cable with another device (worked fine).

-Uninstalled and reinstalled the driver directly from HP and then Realtek. The controller is a Realtek PCIe GBe Family Controller. It shows up in Device Manager each time.

- Checked bios to make sure then the device is enabled and disabled LAN/WAN switching.

- Nuked Windows and reinstalled from disk to get a fresh install. I even tried Win 7 x86.


- Tried safe mode (same result).

Any ideas?

A:4540s Notebook windows boot manager problem

It is likely that there is a problem with either the hard drive or the memory. If either is true it is not going to be possible to restore an operating system unless the bad component is replaced.  Can you get into the BIOS (F10) or diagnostics (F2) at bootup? You should run the hardware testing programs which are available at either place. Let us know what you find or if you have trouble getting there.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.

Ad-Hoc requires that you restart the session each time.

Connectify pro has an auto start option that does this but it's a paid version, connectify lite is free but I'm not sure if has auto start.

I can't turn my computer on. The fans and lights turn on for a second and then turn off. a few seconds later they'll turn back on and then turn back off. I've had this computer for 4+ months now, i built it myself. it recently started doing this but i'd just turn off the PSU (Power Supply Unit) and turn it back on and it woould fix it. now it doesnt fix it anymore. i've re-slotted the RAM (Random Access Memory) and pushed it in firmly, but that hasn't done anything. i've tried different power outlets and pushed everything into the MOBO (Motherboard), i havent messed around with CPU (Processor) because that's just a pain in the a**... i was wondering if there was anything else i could do before having to take it into a local repair shop, lol.

as for my computer specs

CPU (Processor): Fx-6300 AMD
GPU: R9-270x AMD
RAM (Random Access Memory): 8GB Ballistix sport
MOBO (Motherboard): ASRock 970 Extreme3 R2.0
PSU (Power Supply Unit): Corsair X500 w 80+
Case: Rosewill GALAXY

thanks
 

A:Fans turn on, lights blink and then turn off/on repeatedly.

First, I would unplug everything that isn't necessary. Everything external except for the keyboard and monitor. Internally, just leave the CPU, RAM and video card installed. See if it turns on. If not, you might try and test the power button. Disconnect the power button from the mobo. If the pin headers allow for it, use the reset button as the power button. If not, you can use a flat head screwdriver to power on the computer (cross the two pins for the power button with the blade of the screwdriver). If you do this, just be very careful. Touch only the power button pins and nothing else! You could easily damage components by touching the screwdriver to the wrong thing.

Some motherboards have a power button right on the board that you can press to power on the computer. I looked at a pic of your board and didn't notice one.

If that doesn't do it, plug the power button back in. You might try and play around with the RAM. I don't know if you have 2 or 4 sticks of RAM, but try and boot the computer with only one stick of RAM at a time. If there's a bad stick, you'll find it through this process of elimination.

If none of the above works, then it might be a bad PSU.

Running Windows Vista Ultimate.

Display turns off after about fifteen minutes regardless of whether I am actively using the computer or not. The only way to turn the display back on is to close and then open the lid. This disconnets me from AOL, so I have to sign back on again, and if I was emailing, I might lose my current email.

Under Power Options, I have 'Turn off the display' set to Never for both On Battery and Plugged in. Under 'Put the computer to sleep' I have both On battery and Plugged in set to never. Nonetheless, the display still shuts off while I am working.

What do I need to do to prevent the display from turning off at odd intervals?

A:Vista Ultimate x64: turn off display, will not turn back on

sounds like your display drivers are crashing.

Do not rely on windows update drivers - go to graphics chipset manufacturer website and get latest drivers

Hi!
I have this issue that when I turn on my computer, the power LED does not turn on but you can hear the fans working properly. I don't the issue and I'm not much of an expert with computers. Please help me solve this issue because I'm completely clueless.
 

A:Try to turn on my computer but only the fans work and the power led does not turn on

How old is the computer, what was the last change you made to the computer and when you last shut it down did it shut down correctly?

This is driving me crazy. My HP has Windows 7 and everytime it connects to the internet (wireless connection) Windows Live Messenger opens down in the left hand corner taskbar near the start menu. I close it, and fifteen minutes later it will open again.
I opened the options and unchecked the boxes pretaining to 'Run Windows Live Messenger when windows starts' but it still repeatedly opens. I use hotmail, but i really have no use for Messenger. The program is not listed under add/remove programs. Someone please help me turn this thing off.
 

A:Solved: Windows Live Messenger-TURN IT OFF TURN IT OFF!

It should be listed in Programs & Features under Windows Live Messenger or Windows Live Essentials. If you still can't find it listed then go to get.live.com and re-download the installer, reinstall it, then uninstall it.

Hello Folks,

I'm not sure if my issue is with hardware (possibly MB?) or graphics card, so please forgive me if I've posted in the wrong section. The first problem I was having was random blue screens of death that displayed graphic card driver issues. I was able to remedy that by updating my graphic drivers and have not had an issue since.

However, ever since then I have been running into another hardware or graphics-related issue that is random and completely stumping me. What is happening is, I will be on my computer, leave and turn my monitor off, and (randomly) when I come back to use my computer again, when I turn on the monitor there is no signal and a black screen (e.g. when I turn my monitor on my desktop will pop up and the light on my monitor will turn blue, when it doesn't turn on there will be a black screen and the light on the monitor stays yellow as if it is idle). I have tried swapping out the monitor to see if that was the issue and the same problem persists, so it does not appear to be my monitor or VGA cables.

The only way I can temporarily fix this issue is to reboot/restart my computer and viola! The monitor works again and I can see everything. This issue is very random. Sometimes I can go weeks without an incident, other times this is happening a couple times a week. I honestly don't know if it's my motherboard or video card or what. My PC isn't overheating, I'm not overclocking, and all of my drivers are updated.

I'm not sure what... Read more

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

I want to discontinue use of McAfee (which came with the initial install) of my Windows 10 computer, and turn on Windows Defender.   I don't know where to start.

A:turn off mcafee and turn on defender in windows 10

Open the start menu. Select  "Control Panel". Select "Programs and Features". Find and select the McAfee program in the list then click "uninstall" at the top of the list. When it has finished uninstalling Windows Defender will activate itself.Go back to Control Panel again and select  "Security and Maintenance" . In the security drop down list it should say Windows Defender is turned on.

I have HP Probook 450 G3 (P5S63EA) and I see that it has an empty M.2 slot.I want to buy for my laptop M.2 SSD and chose several models.Here is Samsung EVO 850 M.2 (MZ-N5E250BW) 250 GB, interface Sata 3, format M.2, memory type TLC 3D V-NANDand  Samsung MZHPV256HDGL-00000 (SM951) 240GB, interface PCIe x4, format M.2, memory type MLC. I read all available technical documentation for my laptop and see that only Sata 3 interface SSDs from HP are for my laptop. What about PCIe x4 in M.2 format? WIll it works on this laptop?Of course PCIe SSDs has very very faster read/write speed! I would prefer to PCIe ssd from Samsung.I read on this forum that other people used Samsung 850 Pro with MLC 3D V-NAND for this laptop as well. But nothing about PCIe x4.Of course Samsung EVO 850 M.2 (about i wrote upper) should works great because in using sata 3 interface in m.2 format. But what about PCIe x4?  Thanks !

Hello, we have 20 of the new Probook 11 G2 min laptops (11.6"). An inserted HDMI cable is not always recognised by the system, or not at all. The sound output plays static (1 sec) before a sound with latest driver. This is Windows 10. We are hoping for a BIOS update to fix the HDMI problem? Thanks.

Hi: There are 4 generations of Probook 450's...G0, G1, G2, G3...so I can't give you the exact driver link. For the  PCI Simple communication controller, go to your notebook's support page, download and install the Intel Management Engine Interface driver. Unfortunately, I don't know the answer to your other question.
