    Macbook A1708 with water damage and problems after removing U2800

    Hi all,

    i got a A1708 with water damage. I cleaned everything and the board started normal. But the next day i got 20v but no booting. Thermal cam showed over 160c (never had a chip getting this burning hot before) in U2800 and some shorts on the caps around it. After removal shortages were gone and i installed a donor U2800 which worked before.
    Sadly now the device stays at 5v, 0,4a and 1,9w and i don't find the problem.USB ports worked fine before.

      Lenovo IdeaPad 3 15IAU7 that suffered water damage
      by Joel Ohana
      Hi,

      I have a Lenovo IdeaPad 3 15IAU7 that suffered water damage. It doesn't turn on (white power light flashes when on button pressed), and the amber light flashes when plugged in.

      Symptoms:
      • Short detected – sparks appear when touching the charging port connection with board with a metal (even a multimeter probe).
      • Visible damage – after cleaning corrosion, I found 4 possibly burnt memory chips near PC3165, labeled UD5, UD6, UD7, and UD8.

      What are my next steps to diagnose and possibly repair it without replacing the entire board? Any guidance would be greatly...

      MacBook Pro M4 16" A3403 on the table with water damage
      by TimSinger
      Hi guys,
      I have a MacBook Pro M4 16" A3403 on the table with water damage. I allready found the problem within a bad cap. As far as my researh went, I couldn't find the schematics and boardview for this MacBook model. They seem not to be released now. So my question is if anybody has a working A3403 on the table and could tell me, which specification this capasator has?
      I attached a photo of the missing cap. It's on the bottom side of the logicbard.

      I am very thankful for your replys.
      Thanks in advanced and best regards from Hamburg Germany...

      by Andreasbest
      Hello!
      Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
      I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
      Is this normal?
      Thanks in advance!
