When I got this laptop two months ago (W520), I discovered this utility Screen Reading Optimization, which automatically rotates your screen, touchpad and keyboard arrows to the laptops orientation. Worked flawlessly.
However, it doesn't anymore. I can hapilly click 'Calibrate' a million times a day, yet it won't rotate my screen anymore. It simply refuses to, no matter how I turn it around.
The only program I'm aware of that uses the same sensor is the Airbag Protection. This displays a graphic of my laptop orientation, and surprise, it works. Except for one bit: if I hold my laptop still for a moment, it automatically updates this new position as being level. However, this could be just some feature of Airbag Protection, I'm not sure.
What can I do to fix this? Reinstalling Screen Reading Optimization didn't work! Help?
