T420 touchpad dies randomly

2012-02-02, 9:35 AM

Hi!

 

T420 touchpad dies and trackpoint keeps on working. Sometimes after some time the trackpoint may also die. After boot, touchpad & trackpad recovers and is working maybe for an hour, or a day. Then it reoccurs.

 

This happens randomly on some T420's, while other T420's doesnt encounter it never-ever. Any tips how to troubleshoot this one? Ran Lenovo PC Doctor and everything is fine, also cant find anything suspicious in Windows logs.

 

Thanks in advance!

Hi eskoj

 

Try to run System Update and update all BIOS and drivers to see if the problems persist.

Happy 2012! :smileytongue::smileyhappy::smileyvery-happy:

If problem persist after BIOS update and updating the drivers. Try to go into BIOS and do a factory restore settings and see if it helps.

Also when your Touchpad stops responding, is it still showing on the device manager?

Could be a hardware issue (ribbon lose?)
