Toshiba Dynabook E8 Laptop screen turns black after two minutes

Hi! I just bought the E8 White Model of Toshiba Dynabook a week ago and when I started using it, I used the power outlet instead of the battery. But recently I tried bringing somewhere and used the battery which was 100% charged. I opened the PC and everything works fine but after two minutes the screen suddenly turns black but the computer is still on? I was wondering if anyone knows what the problem is and how I can fix it? Thanks so much!!!

Does it turn off while in use or if unattended (like a sceensaver)?
Check the power settings in control panel to see if it suspends when not in use, also the montior settings.

it doesnt turn off just the monitor turns blank as if the monitor itself turned off. Even if I am using the laptop at the moment, it just suddenly blanks out

The problem will be the power settings. Open control panel, power settings and alter the settings for when the laptop is running on Battery.

If you are running Windows XP there are Power schemes to provide a simple way to adjust the balance between power consumption and performance. Windows XP Professional includes six default power schemes: Home/Office Desk, Portable/Laptop, Presentation, Always On, Minimal Power Management, and Max Battery.

The Presentation power scheme maximizes battery life by allowing any component except for the display to be turned off when not in use.
