Have to repeatedly turn on computer and turn off computer to get the computer to boot up
If all the answers above do not work, it is possible that your video chip is failing. Laptop video chips are embedded in the motherboard. Over time, too much heat becomes an issue and begins to warp the chip and it begins to lift up slightly from the motherboard creating issues with blank screens when powered up. I've had the same problem with several laptops brought to me for repairs and 90% of the time it was the video chip. For this problem you may need to replace the motherboard with the same exact motherboard which you can find on ebay fairly cheap, and then if you don't feel too comfortable opening your laptop take it to a computer repair place and have it replaced.

Here are some easy things that can sometimes resolve this
problem:
1) Sometimes there can be a static buildup on the mother board. Power
off, remove the battery, remove the power cord and hold the power button in the
on position for at least 30 seconds.
2) If that didn't work- Power down, remove the battery, remove the Hard Drive
and memory modules and reinsert them. Try to power back up
If these things don't work, get back to me for some more ideas.
Hope this helps and have a super day!

Hi,
The display drivers maybe corrupt.
Boot the machine into safe mode. Right click on My Computer (XP) Computer (Vista) and select manage from the sub menu.
When the window pops up select Device Manager.
A device list will populate. When it has look down the list for Display Adapters. Click on the + icon next to Display Adapters to it expands. Right click on the display adapter and select uninstall.
Restart the computer and let it boot in normal mode.
If it boots in normal mode let it detect the Display and install the drivers for it.
I would be a good idea to update the display drivers via the Dell support website.
If it still won't display in normal mode please post back.
Good luck.

Make sure you have not accidentally used the FN+F5 key
That combination sets the laptop to use an external display.
If using that does not give you a display take a small torch (flashlight if in USA) and shine it at an angle on the laptop screen.
If you can see any sort of picture you would be looking at replacement of some minor parts to the laptop screen
Hope this gives you the information you need. If not add any extra information you may have and lets see if we can FixYa

I'd try:
Updating the bios to the latest version
Uninstall video driver and check for newer version
Replace the inverter.
Let me know if any of those suggestions work, if not we can try something else.
