My customer brought me l a Fujitsu A series laptop. When i turn it on with the battery and not plugged to the power socket, it doesn't turn on. I plugged it to the power socket with battery in it. Still it doesn't turn on. But when i plug to the power and the battery removed, now the laptop turns on and loads the windows boot logo and after about 30 seconds it automatically turns off. What might be the problem ?

well looks like DEAD battery. Do you have any way of checking it ?
second part of problem is weak power brick, moment something want more wattage, things go south.
open BIOS and try to stay there. GPU will not power up, should not turn off at all.

If it is the dead battery, the laptop should turn on with the power plug connected in, irrespective of the battery. But, it starts only when it is powered on.

Tried with different battery and different adapters. Result is same. :(
