Not switching on dell laptop.


I have same problem on my Inspiron 1501. It suddenly got switched off and the LED light in the charger light up when i connect the charger to power outlet but it gets off as i connect it ti my system. I have tried that option also i.e. to remove the battery and hold the power button for a minute and then again connecting the battery and charger but it hasn't worked. Please help, i don't want to get it formatted.
