Having problems with your HP Compaq Presario R4000 Notebook ?

Compaq Presario R 4000 to dark when on battery only.

\015 I checked power options and set to minimum battery. Also pressed f5 ( moon icon key) and arrow up key, nothing. Please help. HP tech support charges for any kind of help. I will never buy another HP product again.\015

Answers :

The R4000, or at least mine will appear to be brighter when on battery also. If you press the function key and then the f8 key it will brighten the screen.
