I have a ThinkPad laptop, and whenever I press Alt + Left arrow, my screen rotates to the left. How do I stop this annoying behavior?
According to an answer on this post on TabletPCReview.com:
Do a CTL + ALT + F12.
This will bring up the Intel control panel. Goto 'Hot Keys' tab and uncheck the box 'Enable Hot Keys'.
The "Hot Keys" tab is under "Options and Support".
However, a further post indicates that there are other keys that rotate the screen that don't get disabled by this method.
