Hi,
I have this machine with me in the lab, which had liquid damage.
When visually inspecting the Logic Board, I detected residue under the U9200.
I removed the IC, and when checking the diode values of each pad, I verified that PP2V5_NAND_SSD0 was shorted. The resistance to ground was about 1.8ohm.
I injected tension in the rail and with the thermal camera, I saw that the Nand U9200 was heating up more in some areas. I removed the Nand and the short circuit disappeared.
My doubts are:
Can I replace just one Nand, or do I have to replace them all?
Does Nand have to be from a Logic Board with the same characteristics/same model?
Can i just replace the Nand and format the machine? Or do I always need to reprogram the T2 chip?
Best regards.
