Friends. I beg you to help me in this situation.
Lenovo X240 with a video problem. Native Intel drivers are not installed,
after installation, a black screen. It works with the standard Microsoft driver.
Understanding that there are problems with the video core,
I ordered a motherboard from Lenovo X250.
The laptop turns on, starts up, there is no image on the internal display.
The image is output to the external monitor.
I ordered another motherboard from Lenovo X250.
The laptop turns on, starts up, there is no image on the internal display.

For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

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 -
Hello everyone,
I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.
The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.
Here's what I've tried so far:- When the internal display is disconnected, the laptop works perfectly fine via HDMI.
- The laptop shows an image on the internal display for a few seconds before it shuts down.
- I tried swapping the LCD panel with a known good one.
- I tried swapping the LCD cable

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

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...
