Macbook Pro 16 inch 2019 no power. Data urgently needed to be recovered, no backups were made.
Short on PPBUS_G3H and blown tantalum capacitor.
Even though I was soldering wires in that area - I completely missed the laminate discoloration near the capacitor.
I did not look for the reasons why it failed, data needed to be recovered asap. Having a fully working (with warranty)motherboard was not a priority.
Normally tantalum capacitors can fail due to various factors, including overvoltage, overcurrent, overheating, and manufacturing defects.
It is highly recommended to check for overvoltage or overcurrent, and check the whole power circuit.
