Acer 1642 freezes and will not shut off with switch unless you remove battery. Operates perfectly if using AC power with battery removed. Is this a battery or M/B issue?

    Sorry, should have included that HD has been formatted and clean reload with XP, McAfee and Windows Defender. You can reproduce the condition where notebook freezes, keyboard does not work, will not power off unless battery is removed, by simply installing battery and waiting a few minutes.

    The problem originally started 2 weeks ago and it will also freeze while initially installing XP.

  • dbrown3800 Jan 03, 2009

    I deleted the partition before formatting....I have also used a new HD just to rule out the HD

    It is not a virus or other software issue! I have spent days trying to figure this out. I've completely reloaded all software and within an hour the same problem resurfaces. I believe it is overheating and may have done permanent damage. My unit is four years old - time to buy a new one.

Yep me too - exactly the same thing on aspire 1642 wlmi. problem was battery. tried replacing hard drive, new drivers, HOURS of head scratching time (& visits to two computer 'specialists' !) before I did more research on web & found people with same symptoms and realised problem is battery. Pulled it out and everything works fine.
Battery over 2 years old and not very good to start with I think.. .going for an 8cell now and hope all will be well !!

I had exactly the same problem with shutting down.  Eventually I discovered the problem was the battery.  Remove the battery and it will work fine on the mains supply.  Get a new battery and replace for about £50 if you wish to use remotely.

Sounds like a virus or malware, try this, go to spybot, search and destroy and download thier free program, also AVG. com, also free, and run them both in safe mode, also defrag your hard drive, start,programs, accesories, system tools, defrag, it may run several hours, let it a lone, first spybot, then avg, then defrag

    I hate defender and I disable it and run a different program Adware Pro and spybot, instead of defender, defender has been the cause of problems on more than 1 occasion. Did the newlly formatted drive run after installation or has it been a problem from the start, if it has bee a problem from the begining, it sounds like a driver issue, what motherboard are you running, and do you have the right motherboard, sats, etc, I used Driver genius available here, you would have to join the site "fof free" then could have access to the software mentioned, I know that site well and have been on it for a dozen years, i't's up to you weather you want to pay for a driver checking program that you will likelly only use once or twice, but I am a tech and it still found 25 driver updates in my SLI machine. Sli runs dual 7900gt's. So it's up to you I can tell you that I never got any infection of any kind from anything on that site, good luck, and if it works for you please all I ask is that you rate it higher, it affects the way we get compensated, thanks, and I think the driver thing is what it is

    Ok, see now we are getting someware, if we need to do this one line at a time ,i'm here, First - Did you fdisk or formatt the drive before the install?

  • George Bill
    George Bill Jan 04, 2009

    There is one thing left to try, can you get to the motherboard, if so, then jump the cmos and pop out the battery for 5 minutes, if after you put it back together it still does the same thing, then it is something internal with the board, also if you still are under warranty with it. Then don't go any farther, as taking it apart will void and warranty yo may have. I am really stumped on this, other than a real bad trojen that came along for the ride on the lats format. Just so you know, and you sound like you know more than most, unless you fdisk a drive I have seen an infected drive formatted and still have the infection.The only way to really get it out is to FDSK it. But try the cmos thing first. If you were local I could tell with a couple of diagnostic programs I have, but that is the only problem with doing repairs through a website. I fixed a couple of fellas laptops last week and needed to have them restart to change settings, and I didn't realize that once they were out of the cue, I wasn't able to get them back, until I searched through the entire cue, Duh

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start

Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

Are 2002 Aztec computers compatible

I am assuming you are discussing the 2002 Pontiac Aztec, the early crossover with the rather distinctive look. I would assume that since they were made by the same manufacturer and they used the same parts that their computers should be compatible. I can't say so for certain as you haven't provided much information, but, unless one of the Aztec owner swapped out the original computer and replaced it with an updated device, the computers should be compatible.

If you are thinking of trying to swap computer chips, I would advise you to wait and let a professional do it at an independent shop. The reason I suggest this is simple, unless you know how to access the computer chip correctly, you risk accidentally ruining it. If you handle the replacement chip incorrectly it is entirely possible that for a stray static charge to ruin the chip by blowing out a trace. Also, if you damaged the socket from which the original chip was removed then it is possible that you will not be able to reinsert the new device without bending any leads on the bottom. If the leads are damaged, then the new computer won't work.

Even if the new computer chip and the original chip were already installed in installable cases (the way most desktop computer chips are installed), it is possible that when you removed the computer, you might have damaged the receiving socket which means that when you go to insert the new computer carrier it won't work correctly because a few or many of the pins on the bottom of the board won't sit correctly.

How to remove a bios password from hp 6720s

Why can't people put a problem in the right catagory?
Generally, you can remove the Bios backup battery or use the jumper on the motherboard to reset the bios completely.
Google "reset bios" to get an idea of how to do it, or do the same in Youtube for a video. Lots of them are out there.

How do I get the battery out of my acer laptop

Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Button keeps blinking

It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at

Freezes on the warm boot screen MC9000

This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.
