I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.

Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

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.

- Bios version : 2.50 (not 100% sure, that's what I remember)
- Upgrade screen, keyboard, trackpad, RAM and CPU
- Reboot and use the laptop for a bit : everything is working fine
- Shutdown (no power) and upgrade WIFI with unsupported chip (AX210)
- Boot up the device : bios warning, as expected
- Shutdown the device again (no power)
- Connect the 8-pin clip of a CH341a

Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....
Working...
