I have a MSI Wind U123 Netbook ... all of a sudden lately, the touch-pad refuses to work correctly unless the LAN cable is connected and active. If i unplug the LAN cable, I can't control the mouse pointer and it starts running fast and jumping; it even clicks on its own sometimes.
My only options now are to use a USB mouse or to keep LAN connected and active everywhere I go (which is not available all the time).
I don't know what happened to it. Where should I start? Any help is really appreciated.
PS: It is hardware related, I've tried Windows XP, Windows 7, and a few Linux distributions and it's the same touch-pad problems in all of these OS's.
