    820-01700-A Short PP1V8_SSD0 and PP2V5_NAND_SSD

    WHAT TO SAY, IN THE ALLEGED CASE THAT IT WORKS. ALSO TRY TO RESTORE THE MAC WITH THE TWO MEMORIES REPLACED AND I GOT THIS ERROR. NOTE: THE MAC LOOKS GOOD. CHARGE WELL, IT HAS GOOD CONSUMPTION BUT GIVES THIS ERROR

    820-01700-A Short PP1V8_SSD0 and PP2V5_NAND_SSD

    after removing U9300 and U9100 the short disappeared. My question is: can these nands be replaced? In case they can be replaced, what should be done after welding the new nands? thanks to all.

    0 V always on LCD_HPD_CONN and DP_INT_HPD unfortunately I don't have a good LCD. Anything else I can do? I would not like to think that the PCH is damaged

    I have a 820-4924-A board, it turns on normally, but no display. It displays image to an external monitor, but its own LCD remains black like it has not been plugged in the board. L8300 5V appear in the first few seconds w/ or w/o LCD connected. PPVOUT_S0_LCDBKLT 0V always. Just 5.1 V pin...

    820-00840-A does not work trackpad and keyboard after customer tried to change battery.

    I already put the trackpad cable in and checked all the pins and they look super good and clean. the FPC also looks excellent. This machine did not suffer from water damage. L / F8400 are good. Something that might seem interesting is that when the machine is on, the power button works to put it...

    820-00840-A does not work trackpad and keyboard after customer tried to change battery.

    The customer brings an 820-00840-A because he tried to change the battery and then the machine did not turn on. Just align the battery in its correct place and the machine started and charged correctly. Once the mac was turned on I discovered that the trackpad and the keyboard did not work only...

    All SPI Bus Series Termination resistors and traces are good. I don't have another 820-00165 that I know of that works well. I extracted the bios and saved the original .bin. Can I do a Clear ME or something similar?

    OK, HERE WE GO. Only 2 pulses when I connect the charger. Approx 5s between each pulse and then held at 23-24 mA. VCORE and PLT_RESET_L is pulsing at the same time. Q8150 and U1950 look super clean. 3v3_S5 / SUS are stable. Something that I forgot to tell before. the trace between U3510 / 5...
