laptop power problem by davidjones24

I have a compaq laptop the power input was accidently reversed - and + reversed does this mean the laptop is kaput or can it be repaired ??. No power light on nothing.

Did it blow a fuse somewhere? :confused: It's worth having a look.. :)

With luck you will merely have popped an internal power supply fuse.

It will be near the power input circuitry when you open the laptop case :)

Cogito ergo sum... maybe?

Take the battery out from the laptop and check the fuse in the plug end of the charger, connect the charger with the battery taken out from the laptop and power on.

............ it might work. :D
