Knowing what the cause of a problem is the hardest step in fixing anything. Here the GPU soldered itself and short-circuited due to a completely blocked air vent and bad apple design. Reflowing or reballing fixed this problem. How do I know? Research, guess and test.

The final test score for the onboard GPU is 1005, where the intel 4000 is 462, which it's about right.

Beside the GPU, this laptop has 3 more hard core problems:
-- The Samsung SSD 840 EVO was extremely slow, and it has been fixed by a firmware update.
-- The power button is dead. The button contact is made from the soft metal on the flex stripe, so it's designed to fail, and it has been fixed with a hard-wire button to the board;
-- The battery is not charging. Searched the internet and kept directed to these retards giving instructions to do a SMC reset. As if a simple software reset or a press a few key combo would solve the problem. It didn't. The cause of this problem is probably due to the prolong under-voltage that the battery package controller simply refuses to accept any new charge. The battery if still in a usable condition, needs to be manually charged up to above the under-voltage level before the charger controller would charge it. This smart charger IC is actually retard in that it doesn't even attempt to tickle charge a completely depleted battery. You can go buy a new battery or you can go fk yourself. The only way to fix this battery is to take it apart and charge each cell up above the under-voltage threshold voltage. This is a 10.95v battery pack, so it has 3 lithium-ion cells, each with a nominal voltage of 10.95/3=3.65v
