Looking for ThinkPad E15 Gen 4 AMD motherboard schematic type 21ED
I have a broken e15 gen 4 AMD I want to fix or have someone fix. Doesn't power on properly just has a power light and fan spins. MOSFET PQ17 is burned out and I want to know what spec it is but I would like to have a schematic to look at or for the shop I may send it to to look at.

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
Hi Guys,
I need a motherboard schematic for file for a AORUS 15P XC please. The EXACT motherboard is ga-rx5lxc rev2.0. It currently has a black screen issue and doesn't display to external display but boots into windows and can also display externally when running ubuntu. If anyone has a motherboard schematic file and boardview for this laptop it would be greatly appreciated. Thanks in advance!05-01-2025, 01:45 PM -
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.
The motherboard starts, the fan spins but no display. It turns off by itself. I restart it and it does start but stays on...08-12-2024, 02:01 PM
