The macbook entered wet and with sulfate in this area: It has been cleaned, I replace the components and now there is no chime: green - orange led, cpu heats up and there is usb activity. PPBUS_G3H = 12.57V PPDCIN_G3H_ISOL = 20.30V PPDCIN_G3H = 20.30V PP3V42_G3H = 3.43V PPVRTC_G3H = 3.33V...

Hi! I have this PCB without traces of humidity but it does't turn on: - PP5V_SUS: 0V (not short) Greetings and thanks.

Hello! The Macbook comes wet in several areas and after analyzing the power-up sequence, it has the following voltages (I'm omitting some that are present): PP1V8_SLPS2R 0-1.8 VARIES PP1V8_AWAKE - 0-1.8 VARIES PP3V3_AWAKE - 0-3.3 VARIES PMU_PVDDMAIN_EN - 0V PP3V_G3H_RTC - 0-3V VARIES P5VG3S_EN...

Hi! I have a problem with an 820-2330 that doesn't turn on: it has these voltages. PPBUS_G3H = 12.66 PP3V42_G3H = 3.41 PP5V_S3 = 0V PP3V3_S5 = 3.3 Thanks.

The customer tried to change the battery and after that, it stays at the logo. I have tried to boot from an external hard drive/pendrive and they never fully load. Any suggestion?

Hi, The PCB had short on C4910 (PP3V3_G3H_T), I replaced with a C of equal value but it still won't turn on. Following the thread https://boards.rossmanngroup.com/threads/820-01041-stuck-at-5v.55802/, I put the voltages: PPBUS_G3H: 12.31V "U7800 SYM 1 of 4: PP3V3_G3H_SOCPMU = 0.6V...

Hi! There was spill in the U7100 and U7501 area, so I replaced the two ICs and some components around them. Now the macbook can start and work (fans spin very fast), but it does not charge and puts "repair" in the battery state. The charger led blinks green twice, stays steady for 1 second and...

Good afternoon mates. The board is already manipulated (traces of flux) and there're no traces of liquid: - PPBUS_G3H: 12.53 V - PPBUS_HS_CPU: 12.53 V - PPBUS_HS_GPU: 12.53 V - PP3V3_G3H: 3.0 V - PP5V_S5: 4.99 - PP3V3_S5: 3.3 V - PP3V3_SUS: 0V - PP1V8_SUS: 0V - PPVCC_S0_CPU: 0V - PPVCC_S0_CPU...

Hello everybody. The macbook had liquid damage around U7000, it was changed for a donor but, there are problems in power on. When I try to turn it on, it marks me as having no battery and after 15-20 minutes of letting it charge, it turns on with + 50% battery. The failure is random since...

Good afternoon. I got an 820-3476 that did not turn on: ppbus gave 0.60V. I reballing SMC and it turned on but it had a graphics error: the system detects 15mb on the graphics card and 42 "on the screen. I have tried 3 SMC's from donor boards and none works: it only gets started with smc...

Good afternoon, guys. The MacBook had gotten wet, the damaged components have already been replaced (including CD3217), it manages to go up to 20V - 1.30A but it resets to 0A. Reviewing the Power sequencing diagram, the voltages reach the part of H9M LOAD SECURE ROM, SMC BATTERY TRAP: the last...
