(10:06) I would proceed like this: 1.- Verify that there is no very low reading or short circuit on the terminals of the ceramic capacitors connected directly to pins 2, 22, 23 and 29 of the TPS51220A IC. 2.- Verify that resistors R112, R725, R392 connected to pins 26, 3 and 31 of the IC are not open (infinite reading). 3.- What reading in Ohms and then in the diode test function do you get on pin 12 of the IC? Now yes, without hesitation I would replace the IC with a new one and repeat the measurements in the previous three steps. Thank you very much for your time and sharing. All the best.
Nice review. Interesting to see how the circuits are different from HP laptops that I mostly deal with.

THANKS FOR REPAIR SHARING BROTHER
Excellent

I plan to appropriate your "congregation of dirt" expression. That's a keeper.
i have broken 2 working laptops as a newbie here.
