Acer laptop's built-in keyboard and mouse not working in Windows

Acer laptop's built-in keyboard and mouse not working in Windows I have been asked to help with an Acer laptop. It has worked fine with a dual-boot configuration (Arch Linux/Windows XP) for some time. Then the user decided to replace XP with Windows 7, which still worked fine. Weeks later when booting up windows 7 the laptop's PS/2 mouse and keyboard did not respond.

Had the same issue with my Acer Aspire notebook, of all things it turned out the battery was shot, once i removed it from the laptop the internal mouse and keyboard again worked normally.

"If it's failing in all versions of Windows but not in Arch Linux ... that's impossible, I would have said.

Except ... it clearly works in the Windows INSTALLER or you couldn't have finished the install, right? Windows has to be installing the wrong driver for the keyboard and mouse. You could try using an external keyboard to install a different driver from the Control Panel."

"Rather than guess what Windows does or doesn't see, can you tell us what it says it has in the device manager, ie whether does Windows not see the devices at all, or sees them with some sort of problem.

The solution to the problem is probably different depending on whether or not Windows can see the actual devices. You may have to change the BIOS or tell Windows to use the correct driver but that's a bit of a guess."

"My best guess is:
Drivers: I think maybe trying older drivers for usb/keyboard/mouse might help.

I've had a problem with my graphics card that a certain version of drivers didn't crash my windows. Sometimes Windows updates the drivers or updates some part that uses the drivers that can cause failure.

Maybe try some analyser like SIW. Maybe it can dig up some useful information."
