Is there any backlight?

HI,

Why do you say it turns on? is the fan making noise ? or is it just that you see one or more leds lit ??

Okay so when you plug the power adapter in, your laptop automatically turns on, but no screen is shown?

Have you done a recent repair on the device?

More details! :3
