I bought an Asus UX535LI with liquid damage and I would like to have schematic.
Not received the laptop yet.
Thank you.

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... -
Hi!
I have an Asus ROG with some liquid.
I already replaced most of the damaged components.
But there are some resistors that have OL resistance but i don't have the exact value to replace them.
In boardview it carries a signal called VRAM_DGPU_TON.
First is 2.2 Ohm 5% (R67218)
Second is 499K Ohm 1% (R67217)
also R6016 Measures 210k instead of the 130k in boardview.
It's part of AC_SHORT_DETECTION circuit.
Should I replace that?
I have 1 ohm, 3.3 ohm, 100k, 470K resistors.
Is it OK to use those... -
Hi,
I have got a water damage Asus Zenbook UX3404 (exact model no. UX3404VC-PURE5) where one of its component got burned, picture attached. MARKING ON COMPONENT is ONLY 5k6 !!
Wondering does anyone know what is that component, it is located near the GPU. I have found out the same component near the LVDS cable on and that is how conclude that the suspected burned component

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....09-01-2021, 09:31 AM -
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...
