Hi, I've got a fairly old Thinkpad T43 laptop that's been working fine for years. Just yesterday the touchpad (and mouse buttons too) sometimes became completely unresponsive. I'd have to close the lid of the computer, go into sleep mode, then open it up and come back out of it... then it would work. For a while anyway, until it started doing it again without warning. Right now it's working okay but could freeze up at any moment.
I didn't do any Windows Updates or anything to the system that could have changed it, so it's puzzling. I checked in Device Manager and can see the driver for it is pretty old (2004), and there's a much newer driver from 2014 available here:
Should that be my first plan of attack? Would appreciate any advice.
