Hi, I have an A2337 (820-02016) which is draining the battery while it is sleep mode. (Like 20-30% during the night) Note: - Battery has 100% health, so basically new.

Hi, after a CD3217 replacement the MacBook Pro M1 (A2338 / 820-02020) no longer boots into the OS and it shows the "restore" screen. I have noticed that PPBUS_AON is 11.98V instead of 12.3V, any idea where I should start? Note: - Device restore via AC2 doesnt work ... Error 4014. - PP5V_S2 =...

Hi, Im facing keyboard and trackpad issues (no function) on an A2337 (820-02016 / MacBook Air M1). I have already tried the following: Replaced the flex cable (between logic board and trackpad) Tried another top case (same issue) Replaced UT330 and UT355 IPD_SPI_EN_CON = 0.596 IPD_SPI_EN =...

Hi, I have here an A1989 (820-00850) with a water damage on J8500 between PIN 1 , 3 and 43. Note: EDP_INT_AUX_N is shorted to ground - so I guess the onboard GPU got fried by the backlight circuit (PPVOUT_S0_LCDBKLT), right? I was able to restore the device via AC2 - no issue. But im not...

Hi, I have here an A1990 - Touchbar doesnt work. (no signs of life) Note: J5100 was corroded - cleaned it and removed the corrosion. (Flexcable was fine) J5100 power lines: - PP1V8_SLPS2RSW_DFR: 1.8V - PP5V_G3S_DFR_FILT: 5.1V J5110 power lines: - PP1V8_SLPS2RSW_DFR: 1.8V - PP3V3_G3HSW_DFR...

Hi, i have here a „820-01041-07“ with PPBUS_G3H on 12.23V. When I connect it to the charger (just the logicboard / without battery) I’m getting 19.6V / 0.00-0.05A (it’s power cycling). Already tried a DFU restore via AC2, sadly it ends with an error. (T2 is getting warm during DFU restore)...

Hi, I have a MacBook Pro M1 which doesn't recognize the battery (0% - Cross Icon). PPVBAT_AON (with charger and battery connected) = 11.96V PPVBAT_AON (without charger and battery connected) = 1.4V PPVBAT_AON_CHRG_REG = 11.96V PPDCIN_AON_CHRG_R = 20V I assume the board is fine because both...

Hi, MacBook Air (M1) got water damaged in area of the CD3217 (USBC0) ... device is able to boot. - 20V boost is working fine which means that the CD3217 is fine - Issue: Unable to power USB device on USBC0 port // USBC1 port is working fine. What should I check first? Is there something wrong...

Hi, I have here an A1989 where the left USB-C ports are not recogizing any peripherals - charging is working - right side no issues. Could it be that the THB IC is damaged or corroded? (Should I reflow the IC?) Note: The MacBook was water damaged in that area, (U3200 was bad)

Hi, every had such a strange behaviour on an A1989?

Hi, PPBUS_G3H is looping between 12.25 and 12.57V on an A1989 (820-00850). Also the output of the USB-C ports are weird. - 19.4V - 0.00-0.04A I assume the CD3215s are fine because I get 20V, right? What should I check next?

Hi, I have here an A1989 with no image/no backlight. Water damage: -> water_damage.png Note: - External display shows image - so the internal GPU is working fine. - " EDP_INT_AUX_N " = 0.007 (diode mode) / 3.4ohms to ground - Is the CPU bad? - Heat shield on LCD getting warm (IMG_0615.jpg) -...

Hi, I have here an A2159 (820-01598) which was water damaged. (I took pictures before cleaning - please check the attachments) After removing/replacing the broken stuff (caps, 94AGTJIELC180) and cleaning the corrotion the device booted fine .... it also worked for 2 whole days. But after...

Hi, Video: I can successfully restore the BridgeOS (T2) via DFU mode but still no image on the screen, the S0 power rails are (kinda) present. I don’t think that’s a backlight issue because I have checked it with a flashlight still can’t see anything on the screen. - PP5V_S0_BKLT_D = 5V -...
