    software or hardware Keyboard and Mouse problem: Acer Aspire 5601AWLMi

    Hi there,

    Just wanted to check with you guys a problem thats been driving me crazy. Got a Acer Aspire 5601AWLMi to fix and the guy thought it was crashing on the login screen. Turns out its the keyboard and mouse not working. Its a tempermental problem so most of the time this is how it behaves:
    - can access BIOS with F2
    - when get to windows login screen mouse and keyboard don't work (but USB mouse does)
    - ran ubuntu live CD and mouse and keyboard worked
    - take the battery out the laptop and the mouse and keyboard work in windows

    been doing some research. Some posts say its a failing battery that causes it, others say its a faulty southbridge. Tried reinstalling and uninstalling drivers but device manager kept crashing (not sure if its unrelated). I think I have a few possible courses of action
    - tell them to use it without the battery and see if they get problems
    - reinstall windows (something I think I will have to do)
    - get hold of a spare battery from a similar laptop

    Just wondering what everyone on these forums thought and if its a windows fault (would explain why it only happens on windows) or a hardware fault (would explain why it only happens with the battery out).

    I'm quite stuck here so hope you can all help,
    Thanks,
    Dan Gent

    Just to add to this thread as I'm really stuck here.

    An update on what I've done.
    with battery out: Uninstalled and reinstalled Mouse and Keyboard drivers (required restart). On the reboot I put the battery back in and still same problem.
    Reinstalled XP: When it got to the first setup screen where the mouse and keyboard are needed (asking to setup language details), the mouse and keyboard did not work. Had to power off and reboot without the battery in (also, at this point I had to remove the battery to turn it off, holding the power button down did nothing!).

    Does this look like a hardware fault to you guys?

    Thanks,
    Dan Gent

    Is USB set to legacy mode in BIOS?

    Hi kalniel, much thanks for the reply.

    Its only a simple BIOS, Phoenix Bios. Doesn't give many options, and none are to do with USB.

    If you found the following thread already, I apologise, but the cause appears to be a faulty battery (assuming everything works as it should without the battery connected.)

    The fix would be a new battery?
