              Fujitsu U7511 liquid damage, wont turn on anymore, does not respond to charger in any way.
              by av4x
              Good morning, everyone!
              I've gotten my hands on a few laptops with various defects because I want to get more involved in repairing electronics.

              First up is a Fujitsu Lifebook U7511.
              It won't turn on anymore and doesn't respond in any way when you plug in a power adapter.

              Model: Fujitsu Lifebook U7511
              CPU: Intel Core i5-1135G7
              GPU: Intel Iris Xe Graphics
              RAM: 16GB DDR4 - 3,200 MHz
              PCB manufacturer: ASKPCB?
              PCB serial numbers: CP801602, CP7984241-Z4, E239218, CP809978-01

              MacBook Pro A2442 (Board No. 820-02443-05) – Liquid Damage Repair Assistance
              by rounin
              Device Information
              • Model: MacBook Pro 14” M1 Pro (A2442)
              • Logic board number: 820-02443-05

              Original Issue
              The device suffered liquid damage, causing a short circuit on the logic board.
              Near the audio jack area, the CR852 capacitor pad was severely burned, creating a clear short-circuit path. The board could not power on properly.

              Work Performed
              Removed the short circuit by drilling through the board (bypassing the short path) in the CR852 area.

              Current Status
              • When powered on, the screen shows support.apple.com/mac/restore....

              A1466 Macbook Air (Liquid damage repair)
              by mon2
              Hi. Recently serviced a damaged A1466 Macbook Air. Thought to post the issues and resolution for each.

              Macbook AIR Model A1466 Diagnostic 09-01-2021

              Issue: Liquid damaged (beer spill) Macbook AIR will not power up.


              Problems & Resolutions

              1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....

              MacBook Pro 13inch 2017mid (A1706 820-00923-A) - liquid damage - USBC and Display short circuit
              by rilley
              Hello everyone,
              I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.

              I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A

              My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.

              And the resistor L4004 is literally burned.

              From what I see from the schematics, it does not affect any other rails, only the connection to the display...

              MacBook A1989 overheating after liquid damage
              by Jenzo
              Hey everyone,

              Had a MacBook pro 13" 2018 (A1989) come in for liquid damage. The only liquid damage was all around UB400. It was most likely soda, so there wasn't that much corrosion. I reflowed the UB400 and the QB chips with some flux, and replaced the caps/resistors that were in bad shape. Seemed to be working fine at first, but the next day when testing it again, the laptop charges and boots fine, the CPU would overheat, and U7210 would get to 70 degrees Celsius as well. I'm testing with only screen and battery connected at this point.

              I can't figure out how...
