T450s Trackpoint stops working randomly

2019-09-20, 9:34 AM

hey guys

i have a t450s which is still under warranty anyway, running windows 7 64bit.

every now and then when i resume the laptop from hibernation, and i unplug it from power either before resuming hibernation or when its still resuming from hibernation, the trackpoint and the buttons (left/right/middle) stop working either till i restart the computer or delete/reinstall it from device manager.

 

it doesnt happen all the time, and its difficult to replicate it every single time, but like i mentioned it only happens when i resume the laptop and I unplug the power cable. when the power cable is plugged in all the time, i never seem to have this issue.

all the drivers/bios are up to date.

 

any suggestions? could it be a faulty something?

ok bit of investigating. the problem seems to follow the "hard drive".
if i put the HDD into another exact t450s the issue can be replicated on that laptop...so it seems to be a software issue.
any ideas?
at the moment i've changed the antivirus software.
and ive also previously uninstalled/reinstall the synaptics software/driver
