Thinkpad P53 trackpad + trackpoint not working (Windows 10)

[jaggreaney]

Trackpad and TrackPoint stopped working all of a sudden. Ive tried to update the drivers didn't work, checked if the ribbon cables were secure (they were), checked bios settings, booted up a live CD of Linux mint still didn't work. I've tried everything I could think of, but it still doesn't work. Have any of you guys experienced this problem?

Since it didn't correct itself with the Linux environment I'd conclude some sort of hardware problem.

I believe The trackpoint and touchpad rely on each other's presence to function properly. You could try disconnecting one or the other's cable and see if anything improves. I'm also curious if there's a BIOS test for the pointers and what it might say. Otherwise I'd load up the parts shotgun.

It's not that they rely on each other's presence, but rather that they share the same PS/2 port. This means when one of them is misbehaving, the other is affected as well.

But the troubleshooting steps needed is as you say: disconnect one either trackpoint or touchpad cable, then test.

should I start with cables first?
