Yes. Than check Compaq's web site & download any updates that have to do with your battery. Wouldn't hurt to check other updates listed on the site. Than update windows....

Have a Great day!

Hi, I have eMachines E640-N833G25Nnks, P/N: LX.NA102.059, Model: NEW85, S/N: LXNA10205902804E2A1601. It is: proc: AMD Phenom II X3 Mobile Processor N830, graphics: ATI Mobility Radeon HD 4250, mem: 3GB,...


I Googled to see if there was any problems related to battery sensors, seems eMachines laptops don't have that problem, the laptop runs well while plugged in, so it's not internal circuitry, I believe it's a battery problem, as you say charging level has been decreasing progressively, try your battery on another laptop to see if the battery is the problem and just in case try a friend's battery on your laptop to completely eliminate doubts about battery sensors, if you don't have a friend with a similar laptop I would go the safe way and send the battery for replacement, if the store where you bought it is in the same country you should get the laptop there so they check out what's going on, if you live in a different country read the manual or click "eMachines customer support" to see if there's any tech support near your city, I still believe it's a battery problem.
Not I'm gonna give you some advice on taking care of your laptop's battery: - When you get new batteries make sure you charge them at least 12 hours before using it. - If you're not going to use your laptop in a while (one or two weeks) get the battery to full charge and then deattach it from the computer, put it back in if you're going to use it. - If using your battery periodically get it to full charge and deplete your battery's energy completely by using the computer until it turn's off itself and then recharge it completely again at least once a week.
If you have any questions, I'll be glad to help. Have a nice day.

I have a HP Compaq Pressario R3000 laptop that will not turn on. I recieved a message that the batter was low even though it was plugged in. I bought a new plug, still didn't turn on. Bought another...


This seems to be a common problem for this model. Some have reported a loose (or dry) solder connection on the mother board where the power socket is attached. Does it seem to work if you push the plug in harder, even for a second? . You should read this thread... http://www.tomshardware.com/forum/50946-2-compaq-presario-r3000-power-cord-issue It may not be your particular issue, but there is a likelyhood that it is. If you are not handy with delicate work, or a solder iron, I suggest a laptop repair shop. Maybe copy or print a part of the thread to clearly indicate what you want. Good luck

Battery and/or overheating or ?


It is possible that the battery is not charging at all and can't pass electricity to the board. But if its 3yo, its probably really dead.

Also, if you can see a fan not working at all, overheating is also possible.

It is also possible that there is a tiny foreign object capable of conducting electricity, such as human hair, that gets activated at the slightest movement of the laptop by shorting some pins on your board.

So I would suggest to observe more or clean the inside of your laptop if you know how to remove your keyboard.

Compaq nx6320 won't power up


Replace your battery Some laptops don't boot up when no battery is present even it is connected directly on the power supply. Or if not to visit your nearest HP service center. If its still with warranty, use it.

Good luck kabayan. ^_~

New battery will not fully charge


Hi, I have three possible answers!

A.
You're computer may not be capable of charging the full 12 cells. (Its only supposed to have 6). So you will only be able to use half the cells. In this case there is nothing you can do apart from just enjoy the 6 recognised cells.

B.
You computer has not fully recognised the 12 cells so you may need to install drivers from the HP website. Or alternately if you know how to and or have the original windows install disks. Then you can re-install windows and it will probably recognise the new battery properly.

!WARNING THIS WILL ERASE DATA - YOU NEED TO BACK UP YOUR STUFF!

C.
The third option is that the battery is duff, take it back to where you brought it and tell then the problem, they mey be able to help you or give you another battery.

Acer aspire 4920 charging mechanism failed


Most laptops, as in 99%, have one board and everything is on it. They don't really have a power supply since the AC adpater provides DC voltage already. There is just a voltage divider that take the incomming voltage and changes it to the various voltages the machine needs. The charging mechanism is also on the mainboard. I've very seldom seen a seperate power or charging board in a laptop. Unfortunately since you've already replaced the battery and the ac adapter and since the adapter is powering the laptop then there is definitely a problem with the charging circuitry on the mainboard. This isn't something one can repair unless you start changing micro components and ICs on the board which isn't recommended. Looks like a new mainboard or a new laptop is in your future if you want it to run off battery.

Another option is to get an external battery that mimics your ac adapter but that wouldn't give you a very long run time compared to the internal battery.

Don't forget to rate my solution in your premium thread as FixYa if you think I helped solve your problem. Thanks.

Acer aspire 4920g charging mechanism failed


Have you tested the adapter to see if there is any power getting to your notebook period. Use a multimeter to check for DV voltage. If you can't get your multimeter probe into the middle of the plug then I use a paper click to get in there. If your adapter is not supplying any voltage then there is a problem with it. I get a replacement adapter for my wife's Acer on eBay for about $30. Just search eBay for 4920g and you should get quite a few hits for the ac adapter or power cord.

If the adapter is providing power then the motherboard in your notebook is faulty since you've already replaced the battery. A replacement motherboard might be available from eBay. Replacing the motherboard could be complicated depending on your experience so I would leave that up to a notebook technician. An Acer certified shop may also be able to sell you a replacement motherboard.

I don't think it's the motherboard, my money is on the adapter. Test it out or have it tested.
