PP3V3_S5 3.3v PP3V3_S4 0.1v PP3V3_S4_FET_R is missing on U8000... u8000 Bad? Edit: Reflowed u8000 now i got 1.1v on PP3V3_S4

F7140 is 3.6v when only on charger CHGR_ACIN was 3.6v only on charger , once battery plugged in power on and jumps to 3.9 and i think it should be 4.8 calculated by the resistance on 7110 and 7111. I fixed the trace for CHGR_PHASE from C7125 powering on now and charging atm hope will be good...

ok so... found some more damaged around SMC made the connections to make sure all good and replaced Q7130. When laptop plugged in shows green light and orange no power on, but soon as i plug in the battery powers on right away and if i unplug the battery turns off and light stays on.

Update: C7125 was damaged i replaced it and on contact 2 of it the line was broken CHGR_PHASE so i rewired and now powering on only on battery :p

PM_PWRBTN_L reacts when SMC_ONOFF_L pressed

I've soldered 100k on top of r1302 PCH_INTVRMEN is 3.3v now and PP5V_S5 is 5v

Just noticed PP5V_S5 is 4v

1V05_SUS is present :confused: PCH_INTVRMEN 2.2 PCH_INTRUDER_L 3.3

S5_PWRGD - R8141 contact 2 3.42v PM_DSW_PWRGD 3.42 PCH_DSWVRMEN 3.2 PPVRTC_G3H - 3.3 PCH_SRTCRST_L 3.3 RTC_RESET_L - 3.3

No nothing... :confused:

PP3V3_SUS present, PM_PWRBTN_L yes reacts when trying to power on the power pads

no luck ... any idea ?

No pulses. Can you please let me know how to start in SMC bypass? Thank you

All measurement without KB connected but also tried with all connected same result.

After replacing all damaged parts powered on showed picture and after few minutes got stuck and didn't power on again. Tried another I/O board just green light and after 5sec orange... r8141 replaced and rewire the PPBUS_G3H J6100 Removed was with corrosion c7090 & 7091 replaced c7797 replaced...

HI Guys. i have this Air board got it with corrosion on it, replaced all of the parts damaged and rewired the damaged contact on r8141(which i replaced and it shows good measurement 100k) PP3V42_G3H side. The light goes green then orange and the voltage on PPBUS_G3H is 8.6v which i was thinking...

Fount it :) C3280 was shorted replaced it all good powering on now testing :) Thanks so much 2informaticos :cool:

Short on PP3V3_S5 side no voltage on L7560. Looking for any other corrosion liquid damage but everything seems clean

Short on C7870 and all around that line... U7501 Pin 12 - 3.4v Pin 13 - 2v Pin 21 -3.4v Pin 22 - 3.29v Pin 23 - 12.59v Pin 29 - 5.04v

Good Morning :) Measuring without keyboard attached PPBUS_G3H R7005 pin1 16.44v pin2 16.57v F7140 12.59v PP3V3_SUS no voltage PP3V3_S5 no voltage PP5V_S5 5v
