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,
Dan Gent

ok.. i've had the same issue... everything running slower and slower then the keyboard barely working. then not at all... battery has not been able to hold much of a charge for some time now. run just on wall. did the same and tried a repair/reinstall of XP. would load to user then after that would freeze. tried your solution of pulling the battery and it breezes through now. why a worn out battery would compromise the keyboard i don't know.
