Acer V7 ZQY: battery (AP13B8K) suddenly dead

Hello

This laptop is a little more than a year.

The accumulator has been in charge of 30% to something like 70% when I realized that the percentage has not increased more.

I have read the information of the battery (charge status, tension etc.) but it did not and during the withdrawal of feeding, the laptop turns off immediately.

This happened a few months ago. I found a few discussions, saying it might be a bios problem, but the upgrade software does not run: he says that I have to have more than 30% battery left, and now the battery is below this level.

I removed the battery from the laptop and tried to activate it by putting a 100 Ohm resistor between the mass and the Green wire next to the red one (the battery sends a short pulse here every second). The tension on the thread is always zero. Then, either is not the correct activation method or the switch to solid state in the battery is dead.

When the battery is in the laptop, the voltage between the red and black wires is 0.8V...

So dead battery? BIOS problem (if so how can I put it?)? Failure of the motherboard?

Thanks in advance if you have any clues or tips...

Hi Laurent,.

Thank you very much for your help!

I just got one installed a new battery I ordered on a Chinese online store (whose name contains battery shop and portable...). The battery has exactly the same reference (AP13B8K (4ICP6/60/80)). It has the same wiring, even sticker on the left (the mark of Acer wiith sticker is missing however).

It works: the laptop runs without power and electricity network it says that the battery is charging. I hope that it will last more than the first.

Problem solved

  • 1950-battery level suddenly drops to 5%

    Hello

    I have a 1950-902 Satellite. I was wondering if someone could help with the behavior following problem / unusual that began a month ago:

    I have started using the laptop with the battery appears as complete in power management. After that 10 minutes of battery used, as soon as the battery level shows as being about 85%, the indication of battery level suddenly falls to 5%, and the hibernation. When I reload the battery, the charging process takes very little time (about 30 minutes).

    This behavior is repeated everytime I use the battery now.

    What's not?

    Thank you.

    Hi Eleni,

    It seems that some cells in your battery may have failed and consequently the battery can hold only a small portion of the normal load. I suggest that a new battery is needed.

    Kind regards

  • Updating BIOS for Acer Aspire 3000 / battery problems

    So I had a couple of Acer Aspire 3000 who were not working and got one to work...

    But it seems that I am having some problems when the battery is in it - and otherwise fine without him.
    Excessively long Shut Downs that go to the continuous reboots / Touchpad problems, gel, etc.

    Says the battery until it goes to @ 7-8%.  Then the battery does not charge.

    When the power adapter is disconnected - the battery is charge?

    Given that these laptops have been sitting around for a couple / few years... and have been given to me... I do not deny the possibility that the battery is not good. And there was only 1 battery using 2 laptops.

    After that she has charged at 7-8% - I unplugged it the adapter - and it ran for @ 20 min.  and said: '1 HR 30 min remaining"until she was cut.

    I also tried tried the - remove battery unplug adapter and hold the power button for 2 min method - then installed battery and adapter - but nothing helped...

    (On a side - note, which is probably not related - my wifi doesn't seem to be working - even though it appears, it does nothing wrong in. Device Manager - and runs a diagnosis does not help...) I know there are wireless networks but none does not appear! Broadcom 802. 11 g)

    In any case - I saw a post on a different site-say an UPDATE of the BIOS could possibly solve the problem of battery - (wifi may be too)...

    Given that I've NEVER DONE an UPDATE to BIOS; I'll ask NICELY, please walk me but this... with as little as ACKRONYNS and GEEK TALK as Possible (respectfully).  I had heard of this sort of thing - to download the update of the Bios... and I think it can be put on a Falsh player - but is a ZIP and should she be EXTACTED - which I'm not too big? Then "Select (something)? and then maybe restart... So now, I'm willing to give it a try - with some help and input.  THANKING YOU IN ADVANCE!  a link for the download and the proper BIOS UPDATE would be a big departure... - I guesss that goes without saying.

    So, here are some features of the information system: (I hope there enough, but please let me know if you need more)

    Here are some tips to help and troubleshoot battery issues.

    Old battery? Unplug the power to the computer - remove the battery and clean the contacts with a pencil

    them and be careful). Batteries are old, or it could be a problem with the computer.
    Check with the support of the machine system, and many of them have on line forums.

    New Lithium-Ion type battery usually last longer if you do not unload then less than 30%
    However on a laptop that not extend their life a lot. Best is to use the a/c adapter
    When this is possible.

  • Acer Aspire 951822 (battery problem)

    I know that I am relatively new to the community, but keep in mind I'm not a novice exact technology. That being said, I know I have to not buy the best laptop, and I never bought one before hand. Here's the situation:

    I read many forums tent help to solve the problem of load by simply disconnecting the battery. I found myself unable to do. Then I found out about the battery reset button, also does not solve the problem, it was totally useless. When the laptop is turned off and the charger is plugged in, the light with a light bulb behind it blinks orange twice and nothing happens until I turn it on, and then turns blue. When I goto the stop, and after he died, the battery LED flashes orange 1 second apart. The laptop is otherwise fine-other than the fact that I put the charger wherever I am to use it, so I can exclude the adapter being the issue... I think so.

    Please help quickly - if it is irreparable, I need to come back soon.

    Well Yes, that's all. If the battery is internal, but I would go a power reset just to make sure.

    It will be a little tricky, but hit the hole pin battery reset with a paper clip or something similar. You should feel a fairly definitive recession when you press it. If you can, hold button power for 10 to 30 seconds and try again.

    If this fails, I recommend you contact your local I can't think any other troubelshooting and I suspect that the battery does not have.

  • Acer Aspire v3 - 572 g suddenly low fps

    Hello

    Since yesterday evening, I experienced a permanent drop in fps in all games I play (for example, CS etc.).

    Not even a fps drops in some of the older titles, which should not have any problems whatsoever.

    It was not caused by a windows update, since the update was done a few days earlier, and the problem occurs then. (just to be sure, I did a system restore and it does not solve the issue)

    I forced my most powerful graphics processor to work in all circumstances, and the system is set on high performance. I have not installed new programs or made any changes to the system. In fact, the fps drop was so random, I played a game earlier in the day and then a few hours later, when I restarted the game, I was instantly a fps drop from 160 to 50 and it is persistent.

    Basically, Ive tried all solutions there and on Monday im going to get my laptop cleaned of dust, since I him have not done in the 9 months that ive had this laptop.

    The reason why I did this topic was just to maybe get some intel, if could be the possible reasoning behind this fps drop I. Because to me it seems that something is bottlenecking my performance of laptops.

    Or if anyone has some sort of information or ideas, which might work, Id appreciate your time and efforts.

    A few days later all of a sudden the low fps was completely gone, but I have a strong feeling that it was caused by the dust.

    I took it to the service a few days ago and the fps improved even more.

I tried plugging the cable USB root in several different ports on the laptop and its docking station. I saw the monitor sleep USB mode FAQ entry.
