Start laptop up, sounds like its working but screen is blank
We have a laptop that when we switch it on it sounds like it is running but nothing seems to be coming up on the screen. The fan also sounds like it is not working. The machine was recently dropped (Son's machine) but not sure how hard it fell but he said it continued to work after being dropped.

Check keyboard for 'F' keys which relate to screen Functions. Look for brightness UP or DOWN keys and if nothing else works hold down POWER button until it shuts down. Then push button and allow it to start up again. It will run through self-diagnostic testing and will ask if you want to run computer in Safe or Other Modes-pick Normal Mode. Very often this will fix the problem.

try to remove all external device connected to your computer. just leave the keyboad, mouse and monitor connected.
if still a blank screen
remove everything connected to your computer (mouse kyeboard and monitor) restart if nothing happens
open your computer and remove all devices (hard drive, optical drives, memory... restart,,, you should be hearing beeping sounds indicating motherboard is looking for memory. try putting back 1 memory at a time and checking all mem slot. to identify if one of the memory could be causing the blank screen. if both memory will not work try to use known good working memory. if you dont get to hear the beeping sound using a known good working memory. your memory is the problem.
give me more info
