My sister has a G55 which has stopped functioning. It is out of warranty so HP aren't interested, beyond selling her a new one, as she discoverd after spending half an hour on the 'phone to them. Power is reaching the machine, the mains indicator light glows, but there is no other sign of life. My feeling is that an internal fuse may have blown. Does anyone know if the PSU is fused? Were I closer I'd open it to have a look, but a 4 hour drive isn't an option at the moment.
