try booting into safe mode f8 and see if the f key works and your screen gets brighter. if it does not...then it sounds like the back light or the inverter is going.
video drivers dont control most time the back light on a lcd screen.

Hi Laban,

Solution is as follows.

Click START, right click on COMPUTER, and select MANAGE.

Under Device Manager, select MONITOR, and right click on PnP Monitor. Uninstall and delete the drivers.

At the top of the device manager, click the button that scans for hardware changes.
