U7000 mode diode to ground I have continuity pin 17, 18 and 23,

L7690 pin1 3,26v mode ground any short´s at PP3V3_G3H, PP5V_G3S, etc.. The Apple configurator detects the board in lock mode (locking logo) but cannot put it in DFU mode.

hello I need help with this board, no antecedent damages, only sometimes green light no fan spin neither turn on with smc bypass mode some values: ppbus is 1.0v pp3v42 is 3.3v

omg! sorry values only with charger (without battery): PP3V3_G3H - 2,96v PP5V_G3S - 5v PPVIN_G3H_P5VG3S - 12,5v PPVIN_G3H_P3V3G3H - 12,5v PPBUS_G3H - 12,5v PPBUS_HS_CPU - 12,5v

Hello, I need help with this board. It worked correctly but my brother forgot the charger. I tried to connect it to a hotel USB port to charge it and it didn't turn on again. I have checked it under a microscope but I don't see any burned or damaged components with the naked eye. With another...

i fix fuse and now I have short in C7372

3V3_S5= 0,52v 3V3_SUS= 0v remember I don't have continuity in F7140 thanks friend !

U7100 Pin1 = 0v Pin2 = 16v Pin3 = 4,3 Pin9 = 0v Pin12 = 3,3v Pin13 = 3,3v Pin14 = 3,3v Pin15 = 0v Pin17 = 8,5v Pin19 = 5v Pin20 = 5v Pin27 = 16v

flip board and I check again 0v but I have broken F7140

yes with battery I have tried several times, cables etc in case I was wrong in the process and I have not achieved DFU. Voltages: P1V8G3S_DSCHG_EN = 0v P1V8G3S_DSCHG_EN_ = 3,1v (sometimes 3,1 change 2,2 , 3,1 2,2 and after a few minutes stable at 3.1 P1V8G3S_EN= 0v P1V8G3S_SS = 0v P3V3G3S_EN=...

hi, i have again new board dead. no water damage Led green, change to orange, but no fan spin. too I check IC U7501, U7100 I can't see corrosion some voltages: PPDCIN_G3H 16.5 V PP3V42_G3H 3.4 V PPBUS_G3H 0 V PP3V3_S5 3,3 V PP5V_S4RS3 0 V PP3V3_SUS 0 V PP1V2_S3 0 V PP1V8_S3 0V PP1V05_S0 0V...

Good friends, here again, I have this equipment that suddenly turned off and did not turn on again. It has no liquid damage. Doesn't recognize in DFU mode And the input voltage attached photo any ideas? thank so much

Hello, when I have checked the U7501 I have been able to observe corrosion on pin 23, I do not understand how it could have formed without liquid damage. I have cleaned it and it works perfect. thanks a million friend It is the second board with this problem, the previous one was on pin 15...

Check R7100 I don't have value only continuity and R7110 = 480ohms

omg sorry I have only short in L7310/20 but I have my laptop that works perfect and I have the same continuity to ground im check all Lxxxx SMC_PM_G2_EN 3,40v PP3V3_S5_AVREF_SMC 3,26v

PPDCIN_G3H 16.5 V PP3V42_G3H 3.4 V PPBUS_G3H 8.6 V PP3V3_S5 3,30 V PP5V_S4RS3 0 V PP3V3_SUS 0 V PP1V2_S3 0 V PP1V8_S3 0V PP1V05_S0 0V PPVCC_S0_CPU 0V ALL_SYS_PWRGD 0 V U7100 Pin 1 0v Pin 2 16,50v Pin 3 0v Pin 9 0v Pin 12 0v Pin 13 0v Pin 14 0v Pin 15 0v Pin 17 0v Pin 19 5v Pin 20 5v Pin 27 16v...

yes all right, I check again

Hello, it seems like a week of problems with macbook air. Equipment without liquid damage, no history any problems, never repair. Green led and then orange. With the logic board disassembly, the same but the fan does not move. CPU DEAD? some voltages: PPDCIN_G3H 16.5 V PP3V42_G3H 3.4 V...

ok friend yes I have continuity in all points 3,4 with U8750 and J9002 and points 1,2 with R8980/1
