Weird Trackpoint/UltraNav issues

#1 Post by twilysparklez » Fri Feb 23, 2018 1:53 pm

For the past few months I've been trying to figure out why my trackpoint would randomly stop working after putting it into my backpack.

So far I tried these things:
  • Restarted the computer
  • Checked the connection
  • Tried (re)installing Windows 10, Windows 7, and Ubuntu
  • Tried different batteries
  • Changed the keyboard
These issues still persist until the trackpoint randomly starts working again(though removing and reinserting the battery usually fixes it). Would this be a motherboard issue?

I had a similar issue when building a W520, before I added the palmrest, the trackpoint would work intermittently. When I got a palmreat and attached the touchpad, the synaptics drivers started working, and the trackpoint was working good.

Perhaps the connection for the touchpad is coming loose, and causing a similar issue? Maybe try reseating the connection for the touch pad and try installing the synaptics drivers again?
Daily drivers:
T61: Core 2 Duo T7500, 4GB, NVS 140M
W520: Core i7 2670QM, 8GB, Quadro 2000M
T41: Pentium M 745, 1GB, Radeon Mobility 7500

Rest in pieces:
R40e (dead hdd controller)
T43 (Smashed by ex)
