Hi, I'm pretty sure I have a hardware fault here but I thought I'd ask before sending it back to Sony (it is under warranty). The laptop has been working OK but has suddenly developed an annoying problem with the trackpad.
Any action on the trackpad results in the reverse movement by the cursor. Ie if you move you finger down the trackpad, the cursor moves up. It does this for all movement. Plugging in a USB mouse corrects the problem (unplugging reverts) and sometimes docking will correct it until a reboot when it will revert to reverse mode.
I have re-installed the mouse driver, reflashed the bios, and even resorted to a factory rebuild using the Viao recovery process (this wipes the c: partition and rebuilts vista and all the sony drivers and apps. Essentially put the laptop back to the way it was out of the box. Anyway, nothing has resolved the problem. So I'm out of ideas!!!
Any thoughts or suggestions much appreciated.
