I've had my compaq presario cq61 for about 2-3 years. A while back it would occasionally have a kind of shaky/blinky screen but just in the past week it's like the screen has stopped working.


The problem may be due the graphics card or data cable or backlighting.

The data cable can be severed over time though opening and closing the display. This can be replaced.
The backlighting/inverter dies, some-times the windows desktop screen can be seen if one looks carefully. This can also be replaced.

Try connect your notebook to another computer's monitor via VGA or HDMI out.

If this works then the problem lies with your LCD screen.

Take care!

Compaq Presario 2200 won't hold a charge - on or off AC


I have a Compaq Presario 2210US. The wireless toggle button is in front on the right side, slightly under the top of the computer. Feel for it with your fingers or use a flashlight. It glows a bright blue when on.
