Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered... -
Laptop Question
Hello,
I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).
A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when... -
Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.
I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost... -

Hi guys,
Today I pulled 5 Lenovo T420 laptops out of a bin at the rubbish tip, and they're old school laptops and they're all locked with a supervisor password.
In the past I've unlocked similar Lenovo laptops, often I used the trick of shorting a few pins together on the chip on boot to get into the GUI and overwrite the config but it doesn't look like that is working with these laptops. I guess Lenovo fixed that trick? I have unlocked some other HP laptops by reading the chip, running a patch and re-writing back.
But I can't work out these T420...11-11-2023, 10:05 AM
