liquid damage , not charging or powering on
-
Might have some liquid damage (from > 1 year ago, was completely fine until a month ago) - unable to notice anything wrong easily on the motherboard (Core i7, GPU MX250, UX481FLY). I have cleaned parts of the motherboard with some oxidation with solder and flux - did not help.
Laptop does turn on sometimes and is fully functional. However, while it is fully functional - (1) If rebooted, most of the times it enters a restart loop with blank screen (2) Sometimes, it crashes by itself and enters restart loop - with no relation to CPU/GPU load, heat, etc.
I found that If I remove the...07-06-2025, 12:31 AM -
Hi Guys,
I need a motherboard schematic for file for a AORUS 15P XC please. The EXACT motherboard is ga-rx5lxc rev2.0.

Hello everyone,
OK, so here is my issue.
This Lenovo B470 motherboard I am troubleshooting died and I identified it is the discrete Nvidia graphics chip that has lost it's ways!
So I removed it and now I am trying to change this motherboard to use UMA graphics, but I am having an issue interpreting the attached diagram. I have a 10K resistor in at the R2013 position and another one at the R2012. R2010 and R2011 are empty.

I have a Dell Latitude 5590 with motherboard LA-F411P Rev 1.0 that has liquid damage and doesn't turn on anymore when only the charger is plugged in. However, it does turn on when powering it from a battery. I couldn't find schematics for this exact board, but LA-F401P seems to be similar (that post says LA-F411P, but the attached schematics are actually for LA-F401P): https://www.badcaps.net/forum/troubl...oardview-neede... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
