Question about PC Laptops
When I turn on my laptop it acts like it's going to start up normally but then a few seconds later it shuts off and reboots itself over and over again. Nothing comes up on my screen and it just reboots itself constantly.
I had the same black screen problem with my Compaq Presario f700.
I went to the HP website to troubleshoot and found that a hard reset fixes the blank screen issue.
To perform a Hard Reset, unplug the AC power adapter and remove the battery, and then press and hold down the Power button for about 6 seconds. This will drain any residual charge in the capacitors and reset the power management controls to their default condition.
This fixed my problem.
I hope it helps you.

I have been having the exact same problem with the reboot loop. The only way that I can get the laptop to turn on is to remove the battery and the mobo battery and hold down the power button for at least one minute to drain the caps. I then let the laptop sit for at least 30mins, reinstall the batteries and plug it in. Works everytime...
Why does this happen? Well I was just browsing mls.ca looking at houses when it first happened and the screen just went black and I had a 'uh oh' moment. I did a hard reboot and that is when this cycle started. I am certain that the mobo is toast...but then why does it work sometimes???
Oh and I am one week out of warranty :P

This is actually a fairly common problem adn can be caused by lots of things. There are a couple of fixes you might try:
(A) Try interrupting the boot sequence and telling the computer to boot using the last known good configuration. Here's how:
1) Turn the computer on, and press F8 repeatedly until the boot options menu appears (the menu items include "Start Windows Normally," "Use Last Known Good Configuration," etc.).
2) Use the arrow keys to select "Last Known Good Configuration" and press ENTER. The computer should boot correctly.
B) If the above doesn't work, you might try bypassing the hard drive altogether and booting from a boot disk (if you have one) or your Windows CD. Here's how:
1) Put the CD in the CD drive and turn the computer on.
2) As the computer begins to turn on, you should see the message "Press __ to enter setup" (it's usually F1, F2, or F4 - models vary). Press that key.
3) You should then see the Setup screen for the BIOS ("Built-In Operating System") - using the arrows, find the "boot disk priority" settings and select your CD Drive as the first priority.
4) Exit setup, saving changes (usually by pressing F10). The computer should then boot normally using the CD. If this works, the problem could be a virus on your hard drive. I recommend scanning your computer with your Anti-virus software as soon as it boots up.
There are other possible causes of the problem you described, but these are the two most common ones. If neither of the above fixes works, I'll be happy to offer some other ideas.

Remove hard drive( all you need to have is a screw driver to remove the 2 screws that hold the cover of the hard drive and to gently pull up the hard drive), turn compute on, screen now comes on fine, shut computer, re-install hard drive, your computer should now be working fine.
This is for the F700 Compaq series.

I also HAD the same problem. As I booted the computer I set it on it's side and "tapped" the bottom hoping for a loose connection to make contact. Well I could get it to boot that way now and then so once I had it running I did some system repair stuff and it came up with the "nvainda video driver was missing" So I told it to find it and re-install which it did and it has been working flawlessly since. I know what your thinking that a video driver couldn't do that but I noticed as it installed that things like disk driver and network drivers were part of the install. So it worked for me GOOD LUCK.

Found this on another site and it worked!
"no, nothing would come on the screen at all, it would not go into safe mode. But... as I read on here, and much to my disbelief a few stern whacks on the back by the cpu fan exit and she booted up today. I guess I'll never shut it off again lol! I've been burning back up data all day just in case."

Hello, I first had this problem long time ago, and I still have it
though, I have a "ghetto" way to bypass the loop rebooting
When I turn on my computer, as soon as I see the blue light on the power button I press and hold ESCAPE and tap it sometimes
and It then the computer reboots
sometimes I have to tap both ESC and DEL buttons then hold them, and it works
hope this helped some people out there.

I'm having the same problem with an CompaqF 700 lap top. I don't get any screen at all. No bios, nothing. I tried pluging it up to another monitor and still nothing. I know the operating system to be sound. It started by not booting sometimes. The power button does stay on after several booting attempts but that's it.

If you press the f10 just during boot-up then you can reload your os without booting from a cd. Most hp and compaq pcs come with a restore partition to restore from. Hope this helps you all.

If you hold down CTRL+ALT and then repeatedly press DEL when the computer is powering up, you'll get it to go past the compaq screen and boot into windows. Once you see the text at the bottom (e.g: PRESS F2 FOR SYSTEM MESSAGES) etc, you don't have to press CTRL+ALT+DEL anymore.
