In safe mode, Windows did not provide any debug information or error messages related to the problem. The only way to get input to work in Windows was to launch it in safe mode or with external keyboard and mouse plugged in before booting (Windows wouldn't recognise them at runtime and the mentioned workarounds worked 1 out of 3 times at best). We tried Windows 2000, but without any success. Weeks later when booting up windows 7 the laptop's PS/2 mouse and keyboard did not respond.Ī solution seemed to be to format the Windows partition again and reinstall XP, but the mouse and keyboard didn't respond in XP either. Then the user decided to replace XP with Windows 7, which still worked fine. It has worked fine with a dual-boot configuration (Arch Linux/Windows XP) for some time. I have been asked to help with an Acer laptop.
