A friend asked me to look at her laptop. It shuts down within 5
seconds of power up. I tried using a different power supply (which I
had used last time she had asked me to look at it, and previously
diagnosed a faulty power pack). This time, the known working power pack
had the same symptoms i.e. the machine shuts down within 5 seconds of
I suspect the battery, since the lights come on briefly. Is the battery
necessary for mains powered usage? Would a dead battery cause the
laptop to shutdown even when powered from the mains?
Any other information or pointers gratefully received.
