Actually I have a Tecra M4 as well - there's not so many TabletPCs with that display resolution out there Mine has been in repair as well - GPU went too hot Do you have the Toshiba orientation awareness utility installed on your machine or only
what comes with windows?
I removed anything with "Toshiba" in its name when I got the thing (as well as all the other bundleware, but it was nothing compared to what came with my Vaio)
...then I realised I had to re-install Toshiba's Bluetooth stack.
I actually don't know how to restore the accelerometer program, I could probably write a task-switcher program based on it to counter
this little meme.
Mine's been in repairs because of a weak display hinge (twice now, first time I fixed it myself).
