Hp Laptop Keyboard Model 12345 If you go to the power settings (right click on the battery icon), select the additional power settings and then edit the power plan you use. The brightness slider is the wrong way around so if you have it selected for full brightness it is actually completely dark. Move the slider to the other end and save the settings (nothing will happen until you save the settings). The reason it is ok on battery is that the slider is set somewhere in the middle.
