Dell Inspiron 1150 Laptop.
Problem: When I boot the screen lights up for about half a minute and then goes dark. The booting sequence continues properly but the display on the monitor is almost dark. With aid of torch you can just about see the Icons of the Desktop.
When tried with an external Monitor (I tried with two) the same occurred. The external monitor light for some seconds and then went virtually blank - dark. What is going wrong?
