I have an Asus L2000B Laptop, and one day a friend was using it and found unconfortable to use the touchpad, and asked me if he could use one of the mice os another computer in the room, i said sure, why not? Well, it was a ps2 mouse and he hot-pluged it!!! :S Result: the laptop´s keyboard stoped working and so did that ps2 port and also the sole serial port , but not the touchpad. Restarting, cleaning the plug and all that did not work. Now when I boot, i get a 'no keybord present/keyboard error' at startup, however, it works fine in the BIOS and in DOS!?! When Windows boots it lights Num Lock, Caps Lock, Scroll Lock an the keyboard no longer works In Linux, No lights go on, but it doesn't wor either. I'm certain that there is damage to the Serial ports/ PS2 ports chip but it's not all busted and probably just ignores any command and just gives outputs. Now, I've been using a USB keyboard to 'make do' but its very annoying an not very portable. Replacing the MoBo is out of the question as it costs more than the PC is worth. I seek a way around the windows drivers, a simpler less demanding driver!
