Hello all. I have an HP Compaq NC6220 with an issue that I never run into before.
The laptop brigtness is really low, barely visibile. When attached to an external LCD it works perfectly.
At first I though it was the LCD monitor going bad, so I replaced the LCD but the problem did not solve. With the new LCD the brigntenss is always low. I tried to replace the inverter and it did not solve the problem. I tried both, Windows XP and Linux, but the problem is the same. As soon as I boot the laptop and enter the BIOS the brigtness is always low as well. The BIOS doesn't seem to have anything to adjust it. When I am within Windows XP, all the Function keys works, but when I click the brightness keys nothing changes, it doesn't increase nor decrease.
What else could it be?
Thanks in advance.
