Pointing Devices not working

[Caryntjen]

I have a Z61m running on windows Vista 32bits and I'm having problem with my trackpoint and touchpad and their buttons, they're not working!

I reinstalled serveral times the drives and software but doesn't work and still isn't. This morning everything was working fine and then when I booted my laptop it didn't work!

But an extarnal mouse did work, trough USB. Really don't know what to do!
