When they go into hibernation, they usually require your password to get back to normal operation. If it is forced to crash, damage to the system files will occur and that means starting in safe mode, if you can get to it. If you cannot get to the recovery partition I would use your recovery disks that you made when you first got the laptop and let it fix Windows for you automatically.

That blinking cursor is the way in which the BIOS is telling you that Windows is not loading because its most critical, core files have been corrupted beyond repair. The only thing you can do is to reinstall using the recovery cd or your own Windows install disk.

You need your Vista disk to re-install Vista.

If you don't want to go to the expense, download and install Ubuntu, its a free opterating system and now on version 10.4, its pretty good.

when cursor blinks, try to press any key!
tell me what error message it gives than!

It sound like the screen is going bad try to hook it up to and external monitor and see if you have a clear picture if you do it could be a loose connection between the case and the Lcd or the inverter may be failing if yhttp://www.ask.com/bar?q=laptop+repair&page=1&qsrc=0&ab=1&u=http%3A%2F%2Fwww.laptoprepair101.com%2Flaptop%2F2006%2F01%2F04%2Ftoshiba-laptop-overheating%2Fou know how check it your self here is a link to a site that will show you how

It's a hardware issue,
Maybe RAM or hard drive..

Did you get it used? If so the password was set b4 you purchase it, and will not show up when you type,,,It stays hidden.

Your getting this screen because there is a hardware failure. Fix the problem and you wont need the BIOS password.

Press<esc> to enable startup message, This should give you more info on the problem.

Try disconnecting power adapter and removing battery for two minutes. If the laptop still does not boot then there is an hardware problem. You can try taking out and putting back ram modules, but my suggestion is to take the laptop at a repair shop, if you cannot fix it by removing battery.

In Windows XP you can disable hibernation by doing the following:
1. Open Power Options in Control Panel
2. Select the Hibernate tab
3. Clear the checkbox for enabling hibernation
This doesn't work in Vista however because the GUI for Power Options has changed and doesn't offer the ability to disable hibernation. But you can disable hiberation in Vista from the command line if you use admin privileges. Here's how:
1. Press the WINDOWS key and type cmd into the Start Search box but *don't* press ENTER
2. Right-click on cmd in the Programs list and select Run As Administrator
3. Click Continue when the UAC prompt appears
4. Type powercfg -h off and press ENTER

IF this does not help write back.

Check HP's website to see if there is a driver. Otherwise you may be out of luck.
