[SOLVED]820-2936 won't go to sleep

[mooserov]

Tried other Battery indicator light in a different case. R6961 is there and has continuity. I get 3.4v on pin 5 of J6955 whether it's open or closed. Does that mean the other battery indicator light board is bad as well?

Just short R6961 to GND and see if board goes to sleep. Most probable issue would be a damaged J6955 or trace.

if I short to ground it does not go to sleep. resistance from pin 5 of j6955 to pin 1 of R5071 is 103 ohms, so the trace to the SMC is good.

How does that proof the trace to the SMC is good? Diode mode on pin 2 of R6961 would be the proper measurement to verify that.

well, trace from pin 5 throug r6961 to pin 1 of r5071 was good.
reflowed the SMC and now it sleeps. My thinking was the ball for smc lid was cracked. Thanks for the help Duke.
