Hi i've got a problem with my touchpad on Acer Aspire 3690, couple days ago it completely quit working, touchpad + the left and rigth keys on it and the scroll key. When I looked into device manager I saw the exclamation mark beside the SCSI/RAID host Controller. I tried to update or something with that driver with wizard but no result, and also as I turn my laptop on, that wizard turns on and offers me to install it, but at the end it not finds any driver. I re-installed the Synaptic but it didn't help. Thanx for help in advance. Any suggestion will be appreciated E.
