by bloodhoundHi!
I´ve got an Acer C27-1655 AiO computer for repair on my bench.
Mainboard: AX1T_MAIN_PCB
The liquid was mainly in the area of MQ1, the voltage regulator for +VDDQ_MEM (pictures attached).
Symptoms:
When power is connected and power switch is pressed, I get 5V at L1, 3.3V at L2 and 1.8V at LPM5. I also get V1.05A_BYPASS at R442 for PCH.
I also measure 2V on +V1.8U_2.5U_MEM but +VDDQ_VTT and +VDDQ_MEM stay at 0V. +V1.8U_2.5U_MEM is also drawn to 0V if RAM memory is installed.
LPM1, LPM2 and LPM3 stay at 0V.

by av4xGood 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: 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

by mon2Hi. 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....09-01-2021, 09:31 AM - Loading...
