Hello,

If it's doesn't work after checking battery/charger and memory:

Turn on the notebook and point a flashlight to the screen and if you see a darker image of your system booting up, then your lcd backlight isn't working anymore.

It's possible to change the backlight lamps or inverter but you need to know something about electronics.
