[SOLVED] 820-2530 Short to GND PP3V42_G3H

[aurel476]

removed L6995 and short to gnd pin 2 (PP3V42_G3H)

Inject voltage with psu on pin 2 of L6995, 1V nothing heat

resistance to gnd pin 1 of Y2815 10,9 mohms and pin 3 9,9 mohms probably bad Mcp ?

Question is how much current was going in at 1V. You can inject up to 3V safely. At 1 Amp or more something must be getting hot.

Exactly thanks bad U7000 replaced board work but
PPBUS_G3H 12,30V no charge battery and no Led driver button (tried good know), battery and charger good know.
R6950 10K
SMC_LID_R 102K
17/18 and 27/28 of U7000 20ohms
Resistance to gnd pin 10/11 of U7000 3,8K

Diode mod of J6950 :
pin 4 0,543
pin 5 2,762
pin6 0,561
pin 7,8,9 OL

SMC is dead.
