by ekozeko333

Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).

After that, the NX20P5090 power switch was visibly burned and was replaced

Help Disabling Flash Protection Range Registers on Lenovo P360 Tiny BIOS

by abhorsen

Hey guys,

Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.

Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit...

Lenovo x1 nano gen 1 -- bricked -- where to flash the bios/fw

by Nicola Bianchi

Hello!

A few days ago I bricked my Lenovo x1 nano gen 1 while updating the bios/fw from linux.
No the machine power up, but it stuck in a recovery state and I can not do much.

Lenovo X1 Nano Gen 1
Type: 20UN - X021US
S/N: R9 - 10W2D9

I would like to flash a new BIOS/FW on the chip using a CH341a programmer but ... I actually don't know which "chip" on the motherboard to target 🤦‍♂️
So here I am to ask for help.

I opened the laptop and I found a chip that may be the target, on it I've:

Hello everyone.

My issue isn't massive, but I'd like to get this solved since I'm trying to fix a friend's laptop.

A botched BIOS update by Lenovo bricked this laptop, so I used my BIOS programmer to reflash the BIOS on it and saved it from an early demise. All is good now, but the BIOS reports the S/N, MTM and UUID...
