Hi, got 820-01041 board that doesnt boot. Its pulling 5v 0amps from all ports. Diode mode to ground on F7001 gave me 0.09. Removed F7001/F7002. Resistance to ground on system side is 24.4 ohms. On visual inspection i get nothing.

Hi, got an 820-00165 that did not turn on and had liquid damage in the U1930 area, components replaced and now it boots but fan goes full throttle after Apple logo loading bar is more than 70% and into the OS. Chant be changed with any fan control software. All temperature sensors are below 40...

I have a 820-00165 board. When connecting the charger it has green light and the fans spins. The LCD stays black. Keyboard doesnt light and neither does the caps lock key light. CPU gets warm. SCM reset works but PRAM reset doesnt. It also doesnt give image with everything disconnected but the...

Supposedly keyboard and trackpad stopped working after LCD replacement, but angle sensor works good and its oem. PP3V3_S2SW_IPD_F is shorted. I am unsure as to how much voltage to inject since its first time working with this model.

820-00840 with no signs of damage. PPBUS_G3H is 13v. board is missing PP3V3_S0 and PP5V_S0. PM_EN_S0_SW is 0v. R7889 and R7827 have correct values. PMIC_PGH is missing

820-3437 fan spins for a long time but no boot When its spinning but no boot PPVCC_S0_CPU is 1.8v Sometimes after a while it will boot into OS and work all right then shuts down a few minutes in. No boot with SMC bypass. ALL_SYS_PWRGD and AVREF_SMC are 3.3v

820-00840 with 13v on ppbus. PP5V_S5 starts at 0.4v and then drops to 0v (no pulsing). PP3V3_G3H = 3.4v PP3V3_S4 = 1.1v L7670 is pulsing and L7030 is stable 0.9v

820-02773 that boot loops to half loading OS, sometimes not even that. With battery disconnected the loops are seconds long. Tried disconnecting everything. No change. Tried booting in safe mode, it also shuts down on loading boot options. Wont go into DFU mode.

Hi, got 820-02773 with tons of liquid damage, it was turning on after cleaning but not anymore. PPDCIN_USBC_AON = 20v PPBUS_AON = 12v PP3V8_AON = 3.8v PP5V_AON = 5v PPVDD_AWAKE_PCPU = pulsing between 0.5 and 0.7v

U6360 is heating a lot. AUD_3V3_S0 = 3.3v L83_LDO_EN = 2.8v PP1V8_AUDIO = 1.2v PP1V8_AUDIO resistance to ground is 7.7 ohms with U6360 connected and 11 ohms disconnected. I replaced C6361 just in case. Replaced U6360 2 times but still getting hot.

820-00850 no signs of damage, touchbar's touch function just stopped working (display works fine). Tried 2 known working touchbars, no change. PP1V8_DFR is 1.8v. J5100 diode mode (dont have good board to compare but they seem good): TP_DFR_TOUCH_PANEL_DETECT = 0l DFR_TOUCH_LID_OPEN_L = 0l...

820-01041 with no signs of damage. i get 5v on 3 ports and 20v on the XA port. There are no shorts to ground on any of the LDO lines on the CD3215 chips. When on the XA port: PPBUS_G3H = 12.24v but still no boot.

Hi, got an 820-01521 with no audio on speakers, no signs of damage. The audio Jack works but not the internal speakers. Speakers show on OS and volume bar also shows. Tired know working i/o board and flex cable, tried known working speakers. I get 1.8v on AUD_PWR_EN. I also get PP1V8_G3S...

No fan spin no light. PP18V5_DCIN_FUSE is 1.8v and ADAPTER_SENSE is 0v. Tried a different DC in board and no change. Charger is OEM and its working. F6905 has continuity. CHGR_UGATE is 0v. CHGR_LGATE is 0v R6929 is 2k ohms. Diode mode to ground: SMC_BC_ACOK = 0.427 PPBUS_G3H is 0v and...

Hi, got a 820-3115 board that does not boot. Got green light but no fan spin. PPBUS_G3H = 12.5v PP3V42_G3H = 3.4v no PP5V_S5 and PP3V3_S5. Replaced U7200 no change. PPBUS_S5_HS_OTHER_ISNS is 12.5v 5V3V3_REG_EN is 3.3v

820-4924 that shuts down after 30secs -2min. No kernel panic error. In safe mode, SMC bypass it takes way longer to shut down. I tried another motherboard on its chasis and it didnt shut down, so external components are ruled out Voltages after shutdown = PPBUS_G3H = 12.21v PP3V42_G3H =...

It boots with the battery screw but not with the flex cable. Fan spins for a few seconds and screen flashes backlight, then shuts down. Tried several working batteries, no change. Also tried a different data cable. J6950 is not shorted. SCL/SDA lines are 0.369 diode mode to ground. Resistance...

Hi, ive got a 820-3476-A that takes charge normally the first time you connect the charger, but if disconnected and connected again, the light wont turn on and it wont take charge. Taking charge: PPBUS_G3H = 12.54v PP3V42_G3H = 3.4v PP18V5_DCIN_FUSE = 16.25 Not taking charge: PPBUS_G3H =...

Hi, got a 820-3462 that is not taking charge from the battery or charging the battery correctly. If the laptop is shutdown it charges the battery very slow, about 10% per several hours, and even if the battery is charged it will shutdown if charger is disconnected. Tried known working...

PPBUS_G3H is 0.5v, diode mode to ground is 0.113. removed F7140, PPBUS_G3H is 0v. Removed L7130 still no PPBUS_G3H PP3V42_G3H diode mode is 0.256 U7100 basic voltages (F1740 and L7130 removed) 1 = 0v 2 = 16.5v 3 = 4v 9 = 0v 12= 0v 13 = 0v 14 = 0v 15 = 0v 17 = 0v 19 = 5.5v 20 =...
