Power Adapter Problem

Q: Power Adapter Problem

I have an Acer 3690 laptop. Recently the original power adapter went bad. I went to a local computer company and had them order me a new one. The day I got it home and plugged it in the adapter smoked and the plastic split showing bare wires. We returned the adapter and they exchanged it for another one. The day we took the new one home it did the same thing. Any ideas what could be the problem???

Hi everyone.

I know that this is not really entirely related to a Windows 7 computer and especially to these forums, but I really need some advice on this and it would be great if anyone who has experience in voltage, amps and safety for laptop power adapters would be perfect.

My friend has just traveled down to my house for a week but has foolishly forgot his plug for the power socket on his power adapter. He uses this for his computer. Again unrelated becuase it is an Apple 45W MagSafe2 adapter.

So I was wondering if he could simply use a cord like this one below to plug into the adapter?
The black cord is 2.5A 250V~

The adapter is 100-240V~ 1A

These are both for input.

Any help would be greatly appreciated .

A:Power Adapter Problem

That white 'thing' appears to be for an Apple Macintosh MacBook/MacBook Pro [I have a MacBook Pro] and you might not be able use the black cord due to fit, the V-shaped notch in the black plug would have to let it be inserted. But it probably won't hurt to try as it's still a 110/120Volt source.

The MacBook power adapter also came with a piece that replaced that cord and has the prongs to plug directly into a wall socket/extension cord, maybe it's in his Notebook bag.

I bought a Linksys WRT160n v3 wireless router sometime back. I had considerable trouble in just turning it on. There is an FAQ article by CISCO which says that you have to first plug in the adapter in a power outlet and ONLY afterwards plug the other end into the wireless router. I tried that; it works most of the time (>90%) but not always!! The wireless router turns on only by hit and trial in 10% of the cases.

Adding to my woes is that there was a power cut yesterday and after that I am unable to power on this wireless router at all. I have been fiddling with it for hours but with no luck. Is the wireless router dead? Is there anything that I can do to verify the adapter/ router's sanity?

Is anyone facing similar problem?

I went ahead and searched through the forums, but I didn't find anything that may work in my case, so I thought I would ask here.

For the past few months, the battery on the laptop will not charge although it is plugged in correctly - I checked the pin inside the adapter connector, and it is straight as an arrow. Fiddling with it does not fix it at all. I am using the original adapter that came with the laptop. A few weeks ago, I installed the new BIOS, but the problem is still there.

The laptop gets a message during startup that reads
"AC Power Adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect Dell 65W AC Adapter or greater for best system performance. To resolve this issue, try to reset the power adapter."

When the laptop, the battery icon says "plugged in, not charging."

One time, I managed to fix it by unplugging the battery for a while and reinserting it, but after a week or so, it kept happening again.

The laptop is a Dell Inspiron 1521, and it's only 1.5 years old. I understand this may be a battery problem, but those can be rather expensive, and it seems a little soon for the battery to be dying. I'd rather try to rule out anything else before I have to buy another one. I don't have a spare to test it, but is there any other way I can try to figure out what's going on? Or does anyone else have any thoughts on ... Read more

A:Dell Inspiron Power Adapter problem

It's almost certainly the battery. Depending how it was cared for, how much it charged/overcharged, and what type it is, it may not be at all unusual for it to quit after a year and a half. Do you know what type it is (Lithium, NiMH, NiCad, etc.)?

It can't be the adapter if it is powering the machine.

What percentage charge does it say the battery has?

Hi -- not sure if this is the right place for this, so apologies if it's not.

I've had my Dell Inspiron 600m for about a year and half, and in the past couple months, the power adapter seems to "shut off". The green indicator light goes out, and my laptop begins to run on battery power. If I unplug the power adapter and plug it back in, it starts working fine again.

The frequency of this seems to vary, and I can't identify any behaviors I'm doing that are associated with this happening. Sometimes, if I leave my laptop unattended for a couple hours, I'll find that the power adapter has shut off and the battery has drained to the point where the laptop has to go into hibernation mode.

What might be causing this? Is it something wrong with the power adapter itself, or something in the motherboard or laptop itself?

Any advice would be much appreciated!

A:Problem with Dell Inspiron 600m & power adapter

The problem is most likely one of three things. However, I have to ask a two question first!

Do you mean the GREEN light on the AC Adapter or on your Laptop. I am assuming on the AC Adapter for this response.

Do you keep your laptop plugged into the same outlet all of the time? The reason I am asking this is that it could be a bad outlet or the outlet could be damaged and the power supply is simply losing connection at the outlet.

1. Possible outlet problem as in it has a worn plug in and the ac adapter loses contact. This can also happen on a power strip too!

2. Could very well be a failing ac adapter.

3. Could also be caused by the battery.

If #1 is a possibility, try a different wall socket.

If it does it in all sockets, you could remove the battery and plug the AC Adapter into the laptop. It should run without the battery too! This would rule out the battery as being a problem! If the AC Adapter fails without the battery, then it is the AC Adapter. If it works with the battery out, then it is most likely the battery!

Hope this helps!

I plugged in my dead(battery needing charged) laptop only to have the power adapter start making a high pitched whinny sound. The green light will not light up on the box. Any ideas what could be wrong with it? If there is no way to get it back in working order, does anyone know of a cheap and good place to find a new one? And how do I tell if its actually the one I need? My power adapter says its part of the PA 10 Family, It also states 100-240v-1.5a, Output is DC 19.5v 4.62a.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

My laptop will no longer turn on.  When the AC adapter is plugged in, the LED light is white indicating power is arriving at the laptop. However, nothing happens when I push the power button. Troubleshooting steps I have completed already include: Hard reset (several times including after each step below)Tried starting without the batteryRemoved all removable components and reseated themRemoved all removable components as well as bottom cover. Cleaned with compressed air. Put everything back.Nothing appears wrong and nothing happened between the last time it turned on and this time that I am aware of. The laptop is out of warranty, and I am pretty handy with computers. Is there anything that can be suggested short of a hardware replacement that would help get this resolved? TIA

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

Well my solution was simple.
I just removed the battery pack and powered up my notebook. Then I turned off the notebook replaced the battery pack and VOILA. The error message was gone.

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message. My computer is from June 2006 and shouldn't be having this issue so early...or ever. This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue. I'm of course out of warranty, will Dell replace this free of charge?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

A:Power Adapter

Hello aaronbaron,

Reseat the power adapter just means make sure the power adapter is plugged in good on the laptop and the wall outlet. I would try powering off the laptop, unplug the power cord, take the new battery out. Reinstall the new battery only and try to power on the computer. If that does not work plug in the power cord and power up with the new battery installed.

I bought a Dynex USB 2.0 4-Port Hub last week and have decided to add an external power supply to power the hub. The short and terse User Manual notes on the final page that a 5Volt / 2.5 Amp Power Adapter may be connected. I called their customer support number and talked to a lady, but her best advice was return to the store and ask there. My experience with this store over the years has been fat chance for this kind of request. Has anyone got a suggestion as to where I can purchase such a USB Power Adapter?

A:USB Hub Power Adapter

Radio Shack would be a good place to start although you might have to get one of their adjustable models. A Google search should also turn up something.

Can I use 45 Watt adapter for dell inspiron 15 5559?? I got the adapter along with the laptop when I bought it. But a warning is displayed on screen prompting me to use 65 Watt adapter... If so why 65 Watt adapter wasn't given with the laptop instead of 45 Watt?

A:Power adapter

The system is designed to support both 45W and 65W adapters - see the specifications here -
When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.

I have a Inspiron 15 3541 touch screen and "misplaced" my power cord and adapter. I'm using a Dell adapter from a different computer, but when I turned on my laptop, I get a message requiring a system or admin password even before it boots up. Is this because of the different adapter? How many pins did my adapter have? What problems does a different adapter create?

A:Power adapter pins

The password that is showing up before your computer boots sounds like there is a BIOS password set on the computer.  Unfortunately if you don't remember that password then you are probably stuck.  You can probably go online and search and see if there is a way to reset BIOS on the laptop and get it to default and remove the password that is set on it.  If there is a hard drive password though then the only way to remove that if you forgot it is to install a new hard drive as the password will follow the drive, not the computer.
Your power supply should have only 1 pin.  Dell used the same adapter for their computers for a while, they come in different wattage though and if you use an adapter that is too low then it may not be able to charge the battery while you use it or at all.  If the plug fits and it is a Dell charger you should be okay to at least get the computer up and running.  If it is a low wattage charger and the setting is set in BIOS (usually is by default) you'll get a message from your computer telling you that the charger isn't powerful enough to charge the battery while in use.

The Yoga 3 Pro power adapter looks like a normal USB brick, and the cord looks like USB, except with a kink in the connector at the Yoga 3 Pro end. Can I charge my phone or tablet with it?

A:What's with the Yoga 3 Pro power adapter - it's a ...

Yes the Yoga 3 Pro power adapter is a USB charger too!

How does it work?

The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.

Can I charge the Yoga 3 Pro with any USB charger?

No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.

Can I charge a USB device with the Yoga 3 Pro AC adapter?

Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.

Where can I buy spare AC adapters and cords?

AC adapters with cords are sold in the accessories section of the Lenovo store.

Where do I find the part numbers for the AC adapter and cord?

Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.

What are the USB specs of the Yoga 3 charging port?

It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

I have a 20 pin motherboard but the power supply I have available has a 24 pin connector. I've read that you can simply plug them together by offsetting the 24 pin one but so far I don't see that working at all (and 'never the twain shall meet', so to speak). I've found adapters but they all say something akin to

'allows you to connect your existing 20 pin power supply to your new 24-pin compatible motherboard'

You can use it the other way around, correct?



A:20 to 24 pin power supply adapter

Some mainboard connectors are 20+4 pins where the 4 pins unsnap from the 20 pins for use with boards with a 20 pin connector. If your power supply doesn't have that feature you would use an adapter such as this.

I have a 90w power adapter from an older notebook that will work with my HP DV5-1015nr. I transport my notebook between home and office. I'd like to utilize the older power brick, so that I won't need to transport a power brick back and forth. The tips on both adapters, of course, are of a different diameter.      My multi-tester identifies that the tip is hot for both adapters. The problem I have is that the older power brick has two wires: core wire (+) and shield (-), and the newer power adapter has three wires: shield that is connected to the core of tip (+), black that is connected to outer part of cylindrical shaft that must be the ground, and white connected to inner part of cylindrical shaft (also negative?). So do the black and white wires on the newer adapter need to be soldered to the shield on the older one?   

A:Wiring for Power adapter?

Just a guess, since it is 90watt, they may have run the extra wire to carry the load, shield is always much larger than center tip wire. Did you measure voltage and ploarity of all three connections with the brick plugged in? Tip is always + and ouside is always - on a HP, not sure what the third is, see if there is any voltage on it, It could also be some sort of sensor wire for the charging system on the mobo. Better to buy another adapter than smoke the motherboard on the lappy taking a chance. If you want to chance it just connect the two wires that are on the center and outside. Leave the 3rd odd one unconnected. probably can be found used for cheap.

Thanks very much for your help.

My neighbour was given a second-hand computer and asked for my help setting it up.

It is a Dell Optiplex 755 running Win7.

Currently installed graphics is NVidia Quadro FX 3500.

I looked up the service tag and this is not the original card (Original was ATI HD2400XT).

The issue I have is that the FX3500 is an 80W card, with the PCI-E slot having a max of 75W. On booting I get low power warnings from the NVidia card.

The card has a 6 pin PCI-E connection available for the additional power, but the PSU has no PCI-E power cable.

The only free power cables from the PSU are a couple of 15pin SATA cables. I have seen adapter cables for 15pin SATA to 6 pin PCI-E. Are these any good for my situation?

If not, what are the alternatives? New PSU? Different GFX card?

A:Power adapter cable for PCI-E

Based on what you just told us, one of those adapter cables should work just fine.

Do check the Seller Rating. I also look for closest shipper (I want what I want when I want it). You should see all the details in the Ad for what you need, if details are not there, you can move on to the next, or contact the Seller. Either way, they have a very fast return policy if what you ordered does not suit your needs.

I have a compaq nx6325 lap top, which will not turn on at all. The power adapter
shows 18V between the inner and outer ring and appears ok, led on etc.But what's the tiny center connector for in the plug? Should there be a voltage on it to earth, or to the ring connectors?Finally,should I be able to power-up the lap-top with the power adapter plugged in, and the battery out?

A:Power adapter center pin

Sounds like the Centre pin has broken away and lodged itself in the plug. I cannot tell you which is positive and which is negative with regards to the rings on the plug. Because different Manufacturers use different combinations and with that different Voltages too. Generally speaking the outside piece is the male end and the receiving plug is the female -go figure-
Hope this link works you can see what I am mentioning, obviously this is not your cable but for the example of male to female ends the description matches the pictures ( not the 'Y' cord on the link )

I am planning on making this project myself but first I have one question. Here is the project I will be making:

It says I need a 12V DC supply for powering the breadboard. When searching up for 12V DC supplies, I only get power supply's that plug into the wrong wall socket (I live in Australia).
Do I need to get something like the article suggests:

Or can I get something such as this:
If the first option is the only possibility, how do I get the plug to go into my wall socket?
Also, how do I get the other end plugged into the breadboard when the product just has a single plug on the end?

A:What type of power adapter do I need?

You can use the Ebay adaptor, the easiest way to get 2 wires is to get a socket that fits the plug, like this one :- and solder 2 wires to that socket.

The circuit at your link uses a 2 wire plug into the breadboard, you would have to get a similar plug OR you could push bare wires into the breadboard.

OR you could cut the plug off to reveal the 2 wires but they will probably be quite thin and may not connect well if pushed into the breadboard holes.

Hi all. I'm semi-reliably informed that my main board is dead.

If my HD survived whatever traumatic event caused the above, I'd like to attempt to salvage some of the data from it. It's a Maxtor DiamondMax Plus 9 80GB ATA/133, 3.5 series.

So far, Ive found this adapter which seems like what I'll need to connect the HD to a laptop via USB in order for it to show up as a removable drive from which I can pull files. Note: I don't want to open the laptop & connect directly vice the DVDRW as it's still under warranty.

So, my question is ... what's the power source on the adapter for? Is it in case you want the connected drive to function as a working drive as opposed to just a storage device?

(sorry, no doubt this is a really dumb one, hardware's just not my thing )

Hi -

First post for me - but what a helpful site!

I have a Linksys WRT54GX, ver. 2, wireless G router to which I have lost the ac power adapter. The manual lists it as a 12 volt DC 1 amp (12VDC 1 A).

I have been to Radio Shack, Best Buy, and numerous electronic outlets, as well as exhaustive searches on the net, as well as contacting Linksys directly (they will not sell one separate! Imagine that for tech support!).

You guessed it - I cannot find one. I even went to my pack rat brother who probably has beat Noah and has collected at least one, if not two of everything on Earth - just in case, as he says!

Anyone have any idea where I can get one of these things?

The ones I have found are 12VDC but .5a, 1.something amps, but none are 1 amp.

Anything anyone can chime in on would be appreciated.

(No there is no USB connection on the router to draw power from the CPU, either! Darn!)

My internet setup is as follows:

Internet > wireless > 4G router > wireless > Main Router > PC (wired) and other devices (wireless)

As you can see the Main Router (which I connect all of my devices to, because it's faster in terms of internal network speeds and has a longer WI-FI range) connects to the 4G router (which is the access point to the Internet) wirelessly.

I want both routers to be wired. However, the 4G router has only a single Micro USB port which also acts as a power supply and the Main Router has no USB ports.

So what sort of (Micro) USB to Ethernet adapter should I buy (suggestions from experience welcome)?

Is it possible to transfer power from the Main Router through its Ethernet port?

If I use an adapter with a separate power supply, will it supply the 4G router through the Micro USB port?

A client brought a laptop to me, saying his daughter had spilled a little bit of water on it, not a lot though. He said one of his dogs eat through the power supply cable and it is sellotaped up, but he said it does work on the charger. However, he came over with it, and I tried it with the charger plugged in, came on for about 10 seconds, no beeps or anything, could hear the hard drive and fan working, but then it went off again (worked on it in my conservatory). I took it in to my home office, tried it, didn't even start up! Not even the light saying it's charging! However, when I put the power cable in, sparks came off it. Because I am not very dexterous, my mate who normally helps me with these things is on holiday.
However, as he said it worked fine on the charger before, it's probably not the laptop. He also said that the laptop doesn't work without the charger plugged in.
Question now is: Should I get a new charger? (While transporting the laptop, a component in the psu might have gone)

According to the specifications listed on page #8 of your model's User Guide, your power adapter is a dual voltage adapter that will handle a voltage input of 100 to 240 Volts AC.  Since New Zealand's power standard is 230 volts,  all you will need is the plug adapter for the wall socket and you are good to go.

I have recently rescued a 15 inch viewsonic lcd monitor from being trashed at my work. I did not find the ac adapter for it and would like to use one of my old PSU's to run it. Since the power requirements for the monitor are 12.0V 3Amp, I assume I can just use the 12.0V rail on a standard PSU and attach a tip to it (which I have from a broken universal wall-wort). Will this work? Can't I use any power supply/ac adapter that is capable of supplying 3Amps or more of current as long as it is 12.0V? Thanks in advance.

BTW...I did try a duracell battery charger ac adapter that ran at 12.0V and 2.5A for a short period (as to not damage the ac adapter) and found that the monitor works fine (just has a little fraying on the VGA cable). So I know it is worth converting a supply for it.

A:Use a Comp Power Supply as an ac adapter?

A 12-volt supply capable of 3 amps or more is all you need. Just be sure the polarity is right.

I have a 12-port network switch in my shop that's been running off a 5-volt leg of an old computer power supply for several years. At the time, the manufacturer wanted as much for the power supply as I paid for the entire switch and power supply the year before. Old computer power supplies are plentiful around here.

I have the 5110nr, I believe. It's got the GTX960m. I am a tech with over 35 yrs. exp in building and overclocking. I realized that the stock charger seems underpowered, at least the one I received with this unit, which I bought used "like new" on Amazon for $850. I was somewhat let down initially upon testing the system for performance, then I found it would double it's performance when on battery power. This indicated to me that the unit was able to draw more current from the battery than when plugged in. Having an understanding of power requirements and electronics, I realized the unit may benefit from using a higher wattage power supply. I bought this baby intending to run "Project C.A.R.S." which is purportedly the most advanced racing sim ever made, with awesome graphics blowing away all current Xbox/PS4 etc. platforms. I found I could run it reasonably well on battery power with the system dialed in using Intel Extreme and PrecisionX for pushing the CPU & GPU to their comfortable limits. Also something I've learned over the years is it's generally best to use the true HP drivers for GPU, manufacturers tend to custom tweak a given driver for their specififc model giving it the best performance even though the revision is never near the most current. Now, the big reveal... I decided t take a chance and buy a used 230watt HP power supply for $38 amazon, then splice the cord so the power adapter would fit this model. I went from not being able to charge while plug... Read more

now on boot up I get a message

Dell AC power adapter type cannot be determined” or "The AC power adapter wattage and type cannot be determined

I am using the adapter that came with laptop
anyone know how to fix

If new means less than 21 days from shipment, best would be to call Dell and have the system replaced under the 21-day satisfaction guarantee.
If it's more than 21 days since the system shipped, call Dell to start the warranty repair process.

I bought a refurbhsed Pavillion 17-G126DS.  I charged the notebook upon delivery.  The charging light on the computer by the AC adapter input was red when I first plugged it in, then turned white - assuming the battery is fully charged.  I unplugged the AC adapter and turned the computer on.  It worked fine for about an hour.  Then, the computer turned off.  Nothing.  No light on the power on button, nothing.  I plugged the AC adapter on, thinking the battery was old, tried to run the laptop off of AC power, and nothing happened.  I have run the diagnostic on the battery (PASSED) and the adapter (PASSED).  Just today, I tried it again.  The battery has been charging, the white light is on, turned on the computer, and, when plugging in the adapter, the computer turned off and the battery light shows red.  The computer will not turn on. Should I get a new  AC adapter? Thanks! Susan

So.. I see this problem has been posted about before, so I just wanna know what my options are.
This problem actually popped up on me a few months ago, but I was able to remove and insert the power cord a few times and the message would go away and I would be able to charge my battery. But as a month or two passed, it became more finicky, and I had to jiggle with it a little more, but still, I was able to charge my battery and use my laptop wire-free.
Now today, I've been trying all day, and cannot for the life of me get the battery to charge. I get the following message when I plug the wire in.
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
Also, I think its worth nothing that a lot of people mention that this error message comes up while they are booting their Laptops, mine only comes up once Vista is loaded and I attempt to reinsert the cord.
So, I have tried another Dell charger, a 90W one, and the same problem does occur (My original is a 65W). I am planning on getting a different battery tomorrow to see if it is the battery, as this ones usable life was getting quite low, down to barely a half hour per full charge. My warranty, although I'm not sure of the specifics, was not expired when this problem first came up, but is now expired by I would say 2 months at the most.

A:AC Power Adapter Type Cannot Be Determined

At a minimum, the power jack on the mainboard needs to be replaced - if that doesn't fix it or a competent repair shop tells you it won't, you'll need to replace the system board.

I would like to buy an extra travel power adapter (US plugs) for my Cloudbook.  Does anyone know the part number for the adapter? Also, I would like to use an external battery to charge the Cloudbook while travelling.  The external battery has a regular USB 2.0 that's on most external battery chargers, and I would need a cord that goes to the power of the Cloudbook.  Does anyone know of a solution? Thank you.

I have a Toshiba Satellite laptop (circa 2003). I know my laptop battery has been drained for a while and I was almost solely relying on the AC adapter's juice to power my machine. Recently, I lost all power to the laptop. I thought perhaps my battery had finally had it so I bought a new battery. Well, then I couldn't charge my battery, so I bought a new AC adapter. I still have no juice. It looks like the AC adapter is working (the light is on it to show it's getting power) but it's not transferring that power to the machine.

I think it may be a bad connection between the adapter plug and the laptop. I don't know how involved of a fix this is.

Any suggestions on what type of fix might be needed? Is it better to just scrap this laptop and get a new one? Thanks for your help!
