    Asus FX505GT, voltage reading after minor liquid damage

    TLDR:


    Are these voltage readings normal? What should I do next?

    Long story:

    I have an Asus FX505GT laptop that received a small amount of liquid.
    Since then, installing the Intel GPU drivers causes a black screen, then an infinite Windows loading until I uninstall the driver using safe mode.

    The laptop still works when using the default Microsoft display driver, but the video memory shows as unknown in hwinfo.

    Installing the GTX 1650 max-q drivers works, but there does not seem to be any acceleration.

    I don't see any physical signs of the liquid damage on the board, but I do know where it might have been. This is why I checked the voltage in that area.

    Thanks!

      A2141 minor liquid damage, U3100 TOP port dead. Periodically boots to 20V ~1A on other USBC ports
      by abajor
      Just wondering if anybody has seen this issue. I'm assuming that all of the CD3217's are semi functional for the chips to request 20V from the PSU.

      This unit had some soda spattered up into the side vent. I ultrasonic cleaned the board, now getting this weird sometimes requesting 20V behavior, then it goes back to 5.2V ~ 25mA The U3200 jack cycles.
      I'm hoping this is just an issue with some components between the TOP Jack and U3100 and not U3100 itself.

      Not seeing anything unusual on thermals just some of the power supply inductors getting warm when it's requesting...

      16IAH7H minor liquid damage around GPU buck. boardiew and schematic included.
      by GGEZ
      Hi. I have a lenovo 16IAH7H (NM-E231) with a small amount of water spilled on the RT8816CGQWGPU buck converter. When powering on, keyboard lights up, fans will spin slowly. CPU and GPU are getting hot. No image. Not via HDMI either.

      Part number is PU4001. The liquid spillage looked minor so I cleaned it up with some alcohol and cleaned ups some crusty joints with solder and flux.

      BoardView and schematic is provided. The buck converter diagram is on PAGE 107.


      I'm inquiring about any troubleshooting tips like probe points to measure and such. I can...

      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...
