This laptop has been dead for years and a friend brought it to me to see if I can fix it. He said it randomly died one day, the laptop doesn't charge, doesn't power up and is practically a expensive brick.
At first I noticed some weird colouring on the DC inboard as if it had sustained heat damage, but decided to keep searching. The motherboard has 0 visual defects and is practically pristine, I checked the SMC chip and other important components visually and saw nothing. After measuring components with a multimeter with the charger plugged in I noticed that the entire motherboard has no electricity running through it at all except on the 5 pin connector of the DC inboard which read 16 volts when the battery was connected and 14 when the battery wasn't connected.
Aside from that I got slightly shocked right above the battery connector while both the laptop and battery were plugged in but the multimeter still showed 0 voltage readings in that location.
I'd love to fix this laptop, any help is appreciated.
