Lenovo T450s mouse problem

[03bluecoupe]

Lenovo T450s Model 20BXCT01WW - No mouse pointer or control - touch screen is fine

Suddenly when I boot up, either normally or in safe mode - I get no mouse pointer on the screen and using the Trackpoint button doesn't change the focus at all.

I plugged in a wireless USB mouse and it works fine. The option to enable the Trackpad isn't displayed on the Hardware tab of
Mouse Properties either.

If I remove the USB mouse and bring up the Device Manager, "Mice and Other Pointing Devices" isn't listed...

I'm hoping it's not a toasted motherboard. Any ideas or suggestions?

Perhaps you could try Linux, which you don't need to install. It may tell you if it's the hardware or software.

LOL - thanks man - once upon a time I was a Unix/AIX/Linux expert but when I retired, SWMBO needed me to be her Winblows admin so I've been away from Linux for so long I probably couldn't find the /etc dir... lol - Maybe I'll get adventurous and google Linux on Winblows...

Crud, was hoping someone would have a clue. Guess I'm scrod and just have to use a wireless mouse.

Uninstall the current mouse driver.
Reload the Synaptic or Alps driver.
Find out which one here: viewtopic.php?f=68&t=126860
No need to modify the .inf file as described there.

Thanks, did it once but will check out the link.

Ah, that link was for the touchpad. I'm trying to re-enable the track point button (the red button between the B and G/H keys. But thanks

Nope, that driver is for both mouse AND touchpad.
