    MacBook Pro 15" Mid 2010

    Hi,

    I have motherboard that is doing my head in, it just randomly stopped working and when reading the pins the voltage is going 16.5 to 0 back and forth so I must have a short to ground somewhere.

    The 3.3v rail is fine
    5.5 unknown as does not power on.

    I cant get a solid 12v to power on the mobo, I found a few chips getting warm so removed them both for testing but still going 16.5 0.

    Any ideas?

    anyone got the schem?

      maybe, but you have to give the motherboard number. Something like 820-xxxx which is etched onto the motherboard, sometimes well hidden and barely visible.

          MacBook Pro 2018 with Activation Lock
          by envym
          Hi everyone!

          I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

          I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...

          MacBook Pro 15" 2010 820-2850 intermittent charging
          by protocold
          I would like to get some help on a 820-2850 logic board with intermittent charging problem. Sometimes the battery will charge all the way and sometimes magsafe would be cycling between green and orange.

          I have already tried replacing dc-in board, swapping good battery, swapping genuine 85w chargers. None of that helps..

          when it is not intermittent:
          PPVBAT_G3H_CHGR_R is 12.07v

          when it is intermittent:
          When the light is green, PPVBAT_G3H_CHGR_R is 12.99v
          when the light is orange, PPVBAT_G3H_CHGR_R is 11.62v

          data line on the battery...

          General question about MacBook power rails for repair.
          by SarcasticOP
          I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
          • PPBUS_G3H (12.6V-12.8V)
            • This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
          • PP3V42_G3H (3.42V)
            • This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
          • PPVRTC_G3H (3.3V)
            • This
