Are the noises beeps?

Yes - Take note of them and the BIOS manufacturer during boot. Here are the codes and meanings.

Check BIOS boot options and assign local hard drive as first for faster boot. This is also where you set CD\DVD as first to boot from disc. Look for F Key press on start up. It will be shown on screen. These can vary.

Many HP machines also have a boot menu option during boot. Again an F key and may vary.

check you bios pages are correctly configured,,goto bios navigate with "tab" and arrow keys,,play around untill you know these pages dont change anything untill you are sure you know what you are doing..Exit and save pay attention to boot sequence if this is set up wrong it might cause failure in the way you describe,the instructions on the right hand side of the bios pages should help you---good luck --Davey

ran for 2 days on AC pack only?
battery out, be clear there... it must run on ac alone .
the BIOS is next
is the screen with text?" or really is 100% black all the time.
remove the hdd if it makes abnormal noise, and check that BIOS screens work , even take out the DVD drive.
battery is already out. they short. get it out .
then push the bios keys, ESC?
this PC laptop has CCFL lamps that go dead.
so do the flash light trick first. while calling up BIOS.

You can try by taking out the bios battery first it might of died on you theres also a ultimate boot cd you can find and download for free i had this problem before put on usb if you get to the bios screen see if it detects your cd drive once the batterys are out hold power button down for 15 to 30 seconds this should at least give you basic function drivers and make sure you have it detect your hardrive and move boot device to cdrom first then have windows cd in computer on reboot windows xp without sp3 probly wont detect a sata drivenot sure might have to use vista

Hope it will help you.

you have a problem with your screen / onboard graphics / graphics card / vga cable ...

wiggle the cable for starters then maybe try another cable or screen

rate if useful

Your BIOS is more than likely locked by an admin password or the options are locked upon startup. The best way to go around that is once you see the HP screen popup after restart, keep hitting F12 and the boot menu will pop up gving you access to the boot menu and then to the BIOS. If you have a password setup on the BIOS you will need it for any BIOS changes you make to take effect.

When your system begins to come alive, press Esc or F8 to get to a BIOS Menuscreen. In there, look for Boot. Move the CD/DVD option to the top so that your computer will look for a cd to boot from. Hit F10 to save and exit. Put a bootable CD in the drive and let your computer boot from it. Once it's up, look to see if you see your harrdrive C:. If not, the problem is probably the boot sector on your hardrive has gone bad. Look at this site (it's legit) for bootable CDs and other help.
