a customer brought her laptop to me tonight, her son had plugged in to many appliances into a surge protector and has managed to damage the laptop. am not sure if hes fused the laptop or just screwed the power supply. is there any quick way to determine what he has done? the laptop does not power on with or without the external power supply plugged in. she doesnt think it had any charge stored in the battery at time on surge?

Any ideas

thanks
Leo

Try pulling the battery out and see if it fires up on the power supply.

tried that still doesnt fire up

 

I would use a voltmeter to measure the output of the PSU.. Most laptops run at around 15-20V DC, it will be written on the label.

The chances are, the laptops fine and the fault lies with the external PSU.

 

dumb question lol but how would you use a voltmetre to test a external psu?
