Question about Computers & Internet
First thing to try:
Remove your battery and charger, hold the power button for 10-15 seconds. Plug the laptop into mains ONLY leaving the battery out. Try powering it up.
If the laptop powers up ok, simply shut-down and re-insert your battery. You should find your laptop will continue to work fine for the foreseeable future, this kind of issue is a common occurrence on laptops.
If not I would then try re-seating your RAM/Memory, if that doesn't work and you have more than one stick remove one at a time to see if either one is causing the problem. If you have only one stick find a replacement to test your laptop with.
If you are still finding the same issues with the laptop I would then proceed to reseat all components of laptop, including the CPU.
If the issues continue I would then remove all non-essential components one by one, each time attempting to power the laptop. At worst you will eventually end up with just the mainboard, CPU, RAM and an external monitor plugged into the mainboard, that still doesn't function correctly. I would then conclude your mainboard needs replacing.

Take out the memory and reseat each memory stick one stick at a time in each slot one at a time. Be sure to turn on the laptop after each stick reinsertion. If you don't get any video then go ahead and take out the battery completely and only have the AC Adapter hooked up and turn on the laptop, this will make sure that its not an overdrained battery causing the laptop to show no video.
If this doesn't work then go ahead and take out the hard drive and dvd drive, then try turning on the laptop. If you still don't get any video then the last thing to try is to change the output from monitor to LCD, you would do this by pressing the FN key + the function key that has a pic of a monitor or it will say crt/lcd.
If after this last step you can't get video then the motherboard is bad and would have to be replaced.

Does the light associated with the hard drive flicker, stay on and then fade sometimes? If so - then the hard drive is working and the likely problem is a faulty screen. You can also try the function key plus whatever F key would increase screen brightness. (i.e. Fn + F7 on my machine.)
