820-00244 Pulls 1.5A without battery and U7210/L7210 becomes hot on CPUCore line

[it-solve]

Data Recovery Case
I have overheating mark on L7210 which seems to slightly desoldered itself under the heat.

PPVCORE_S0_CPU_PH2 -2.88 Ohm
PPBUS_G3H - 3.18 Ohm




Lifted up 7210/30 and short is gone on PPBUS_G3H. 20V 0.02A on charger
Still 2.88 Ohm on PPVCORE_S0_CPU

Did a blown U7210 fried CPU? Or is there anything else I can do?

Compare CPU core resistance to ground with known good board.
2.88 ohm seems to be very low.

U7210 is burnt for sure, so probably dead CPU...

 

[it-solve]

Seems like a blown CPU. Leaving here for reference

PPVCORE_S0_CPU - 13.7Ohm on a good board
