Hibernate/Stand by Stop Error

This is brand new Toshiba p105-s6157 Laptop bought just a month ago. It came with Windows XP Service Pack 2 installed. Everything is working great except one problem. Whenever I try to put the laptop in Standby or Hybernation, I use to get a BSOD with Stop Kernel error, and it creates a dump file. The complete error message is as follows:

Quote:

A Problem has been detected and window has been shut down to prevent damage to your computer.

If this is the first time you’ve seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to be sure you have adequate disk space. If a driver is identified in the Stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.

Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need
to use Safe Mode to remove or disable components, restart your computer, press F8 to elect Advanced Startup Options, and then
select Safe Mode.
