Hey TPU, My dad has a Sony Vaio laptop. He was surfing the net when all of a sudden his laptop just died. Being home, it is now my responsibility to do some magic and fix everything. I confirmed the charger is working. There is current on the tip that goes into the laptop so it is conducting power. I disconnected the battery and tried running it on Mains directly, but no luck. I'm thinking even if the HDD or RAM or something failed, the LED that indicates the battery is charging should still be showing something. There is absolutely no sign of life in the laptop at all. Any suggestions on what I should check and eliminate to zero in on the problem?
