Why is screen blank?


You never said if it worked with external monitor. You also didn't say if you tried the [fn]+[Fx] key combination on the keyboard to try and switch displays.
But, if you look at the screen closely, at an extreme angle and can faintly see the graphics then that means the backlight has blown out. For the displays with LED backlighting it's usually just a wire or circuit to repair. For the screens with CCFL (fluorescent) lighting it's a simple matter of replacing the inverter board.

Mouse is frozen, i want to reset my notebook and dont know how


Make sure you haven't disabled the Track pad. Check to see if there is any buttons around the Track pad or around the 'F' keys.
If its not that the computer will have more than likely frozen. Just press and hold the Power Button until the screen goes blank. Then turn back on

If the screen shows running in lower power as an error. I think your powersupply isn't supplying enough power to the computer, and probably needs to be replaced.

Labtop Screen Remains Blank


connect to external monitor to rule out bad video card. (remember most laptops have to toggle between internal and external display by using the <FN>+ <F?> key, mine is FN F5.)

If the external works then the problem is
  1. Inverter board or
  2. TAB welds at LCD or
  3. CCFL Cold Cathode Florescent Lamps (backlights)
