    ::Okay, I am hoping someone in this forum might be able to give me a
    little computer help. I am at my wits end. I have an Acer Aspire 3100
    Laptop with the Windows Vista OS, AMD Sempron processor, 80 GB HD, 512
    MB DDR2 (I can?t give any other info due to the fact that I can?t use
    the computer at present and don?t have any of the paperwork because I am
    currently out of the country); I?ve had it about 8 months and have only
    had minimal problems. However, the other day I turned it on to download
    photos from my cell phone to the computer, but when it turned on the
    cursor was frozen in the middle of the screen. I allowed it to sit for a
    few more minutes thinking maybe I didn?t let it boot up completely, but
    it never unfroze. I tried to use the keyboard to maneuver a restart with
    CTRL+ALT+DEL but the keyboard didn?t respond either. So I just turned it
    off using the power switch. I let it sit for a while and then tried a
    reboot. This time it worked. I thought I would attempt some
    troubleshooting so I did a disc cleanup and scheduled a scan disc to be
    completed on restart. Then I began the AVG virus scanner (which has been
    installed on the computer for over 2 months and not given me a problem)
    and a few minutes into the scan the whole computer locked up again (not
    just a program ?not responding?). I let it sit about 15 minutes hoping
    it would unlock, but it didn?t. The cursor was frozen in the middle of
    the screen and the keyboard was not responding again. I turned it off by
    the power switch and let it sit for about an hour. When I turned it back
    on the scan disc I had scheduled began running and when the system
    restarted everything worked again, but then I needed to leave so I put
    the computer to sleep and brought it with me. When I turned the computer
    back on a few hours later everything seemed to be working. I began
    working on a project and maybe 20-30 minutes into the project, the
    computer completely locked up again, cursor in the middle and no
    keyboard function. I did notice that the laptop was running a little hot
    at that point and from then on I have kept it in the coolest place
    possible and keep my house fan blowing on it as well. ::

    ::I am generally pretty good at troubleshooting if I can maneuver but I
    can?t do anything. The last things I did on the computer on the days
    right before it stopped working properly were download photos from my
    cell phone, help a friend of mine create a Skype account (Skype was
    already installed on the computer for about 2 months and working fine
    before I created the account) and authorize a windows update which had
    downloaded and was ready to install. I have attempted to start it in
    safe mode, but even at the bios point I have no keyboard function. I
    have attempted pressing the FN F7 touch pad on/off button thinking maybe
    that could be the problem to no avail. I have also tried using an
    external USB mouse thinking maybe the touchpad is fault, again to no

    :: At this point when I turn the computer on the Acer logo displays and
    then it takes me to a bios screen that says that Windows Error
    Recovery-windows failed to start?it defaults to run Startup Repair and I
    can?t change the selection because the keyboard will not work. So the
    computer runs the Startup Repair wizard which then asks if I want to
    restore using System Restore. Again, I am not able to select Restore
    because neither the keyboard nor the mouse are working. I can go no
    further than that screen and once more am forced to turn the computer
    off by the power switch. I don?t know what is wrong, what caused it to
    go wrong or how to fix it.::

    ::I have spent a good portion of the past 2 days online on a friends
    computer trying to find out more information about what the problem
    might be or what the solution is, but I just keep coming up with
    articles like ?your mouse batteries are dead? (which they aren?t,
    because my mouse is a touchpad) and ?use the keyboard to?? (I can?t
    because the keyboard is not working) and many other rather unhelpful
    ?solutions?. I am at a c

    This looks like a problem with the hardware in the 3100. If you have a
    current warranty you should return the laptop for diagnosis and repair.

    If no warranty is current, it may not be economic to repair. You should be
    able to remove the disk and connect it to a USB adapter and recover your
    data to another machine.

    If you can manage to boot up again here are some things you can try.

    Run sfc /scannow.

    Uninstall the windows update you mentioned.

    From Device Manger uninstall the mouse and keyboard, reboot and allow them
    to reinstall.

    Before AVG were you using Norton or McAfee? They leave bits behind that can
    screw things up.

    Which firewall are you running?

    Which anti-spyware program(s)?

    There are some that don't play nice with Vista.

    I sell and repair Acer laptops, and it sounds like you have tried
    everything possible to sort out the problem, if you cannot turn on the
    touchpad using the FN + F7 keys, you are not going to be able to solve
    the problem and as you have already indicated that you have only had the
    laptop for about 8+ months, it is still under warranty and you should
    get it logged into an Acer repair centre as soon as possible, all you
    need is the serial number from the bottom of the laptop and the proof of

    I have a Acer Aspire 5670 (5672WLMi) and the keyboard and mouse pad quit
    working exactly as described here. I followed the procedure explained by
    bushwacker75 and it's back working perfectly now. I just wanted to say
    thank's for the info bushwacker75! ;-)

    Try this: Take the battery out of the laptop completely. Unplug AC. Wait
    1 minute. Plug AC back in without battery connected. See if it works OK.
    I think You may have a bad battery...... Post here what happened!!!

    Just so you know as a total aside I have been struggling to get the touchpad
    working on my Acer 7720g after I used a USN mouse. I have unistalled the
    mouse drivers, downloaded the ALPS drivers for the touchpad , started looking
    at group privilages and security ( the only lead that Vista help gives ) and
    was getting to my wits end. Why does no one tell you that Fn F7 enables the
    touchpad :) - all ok now both USB and touchpad work .

    I have searched for 2 days, uninstalled, fighting with security, updating,
    and the genious of a person who noticed the Fn F7 needs to be noticed.

    Just an FYI that this issue is still out there and bushwacker's advice
    worked for me too - and I am using Windows XP, not Vista!

    Thanks again Bushwacker! :) :)
