Having problems with your Toshiba Satellite P105-S6104 Notebook ?

Toshiba satellite no dsplay at all just a.c. power led is blinks 3-4 time and steady after.


Answers :

Does the computer start (can you hear it?)
Try to unplug the power supply and battery.
Try to start it with just the power cord and no battery.
If it starts up with no display, then try an external monitor.
Also, test the power adapter--see if it's putting out the required voltage.
Assuming the adapter is good and the battery is good and the computer still won't start, you'll be looking at replacing the motherboard.

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.
