Question about Compaq Presario 700 470024-192 Notebook
When I turn on my computer, the screen is dark. I've tried the function f8 key, but this has no effect.
Definatley the display close power switch, located under switch/speaker panel.im not sure if the hinge activates it or not. looked into mine and found part# tag interfering w/ power switch board, cleaned it up, working good now. discovered this by gently pulling top left and pushing lower right of display, it would flicker.thaught it was closed probably a result of closing it with right side after every shut down.im trying to close only from middle..i also try never to pick it up from one corner, plastic is very bendy and screw comes loose.two hands always, specialy where rom is.i think your monitor thinks its closed. while black hold it under bright light and you can see enough to navigate.tried svid, used it for safemode driver check, took several hours before i got to hinge. i hope this is your troubles as they cost nothing to repair.my warrenty left 22 days ago.i was sweating.hope this helps.

Press on the "Fn," or function, key. It is located in the bottom-left corner of the keyboard, typically next to the "Ctrl," or control, key. Do not depress it.
Press on the "F8" key, which is located in the middle of the Presario's top-most row of keys. You should now be holding down the two keys simultaneously. Small illustrations of a sun and half moon often accompany the F keys allowing you to adjust screen brightness.
Monitor the progress bar that appears on your screen as the brightness increases.
Release the two keys once you have achieved the desired brightness.
