Hey Folks,

I have a 4th gen X1 yoga I'm trying to repair, current state:

- Laptop charges battery fine and or no obvious power circuit faults
- When power button is pressed, keyboard briefly lights up, power button lights up and stays on, brief fan spin
- No display or back light, does not respond to external display, and caps lock does not work (no response to keyboard presses)
- If device is left on the CPU fan will ramp up/down as the CPU warms up

To me it seems the device fails to POST, I have tried flashing a 20QF bios from the bios...

Hello.
I received a yoga 6th gen ( nm-d341 ) that is not charging, tried both charging and thuderbolt ports but no charge, i don't see any physical damage on them, in fact they look like new.
When i use charged battery works great, i updated to latest bios as i saw a warning from lenovo regarding urgent update to fix charge problems and also updated ME firmware, no luck.
What do you suggest?

Hi everyone, hope everyone's having a great day.

I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
Does this mean the BIOS is fine? making it a hardware issue?

I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...
