Hi!
I need some help for the laptop specified in the title.
It's owned by a friend of mine. At first, it started displaying only a black screen and fan spinning. Then he tried doing an homemade reflow on the VGA BGA. After that, it could be turned on every time for a short second with no fans nor anything (LEDS only), then shutting down (just before shutting down you can hear a slight pop on the board, source unidentified). After three or 4 attempts, he said the laptop squealed for a moment the shut down forever. Now it shows no signs of life with the AC adapter connected, the B+ shows almost short to GND (2.6 Ohms).

How can I go on diagnosing the fault?
Thank you so much!!
