This arrived with no power. When plugged in you get the low battery symbol but nothing else. No liquid damage. PPBUS_G3H is 12.80V. PPDCIN_G3H is not shorted.
Read on another post battery is not required for this board. When battery is disconnected the board only goes up to 0.20amps and drops...
Does it seem fixable?? Sounds like hopeless project since CPU and GPU can’t be replaced on these. Is there any chance it could be their power ICs or something else in the circuit??
R7061/62 reading anywhere from 1.6-2ohm
C7020 21.5 ohm red probe C7020 black probe ground ohm modes
R7060 and traces to U7000 are fine. When the board first boots with battery and charger connected (after both have been disconnected) it appears to be charging fine, however once charger is...
This issue just randomly started for the customer. They claim it happens while they are using YouTube or even conferencing. Board is clean with no burn spots or liquid damage.
See attached picture for crash details. Any ideas what could cause this?
This arrived with no liquid damage. Issue is when charger is plugged in it will act as though its being plugged in and out every few seconds. PPBUS_G3H voltage with charger and battery 11.15V. 11.50v with battery alone.
12.65v with charger alone but only low battery symbol appears on the...
This arrived for liquid damage repair on 10/2020 and just recently came back for no power. PPBUS_G3H is shorted. Resistance to ground 0.06. Checked all big coils but none of them have the same resistance to ground. Injected 1v into PPBUS_G3H drawing .900amps but nothing is getting warm.
Since...
Can you advise on what to check or try next?
Have a good board besides this one and all components are present. The only diode measurement that is off is PP3V3_G3H_RTC good board is around .350 but only 0.085 on this board but cannot be a short since 3.3V is still present
