        Summary of BIOS Whitelist Removal Problem


        Problem:

        Initial Findings:

        Lenovo Thinkpad X1 carbon 11th Gen BIOS problem
        by MaxonDomkrat
        Hi everyone.

        I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...

        Lenovo V310-15IKB Type 80T3 laptop, i7 7th cpu with dedicated Ati video
        sn LR09493E
        MB DAOLV6MB6F0 REV. F

        The laptop was working fine, the only problem was that when I turned it on, the screen was hard to turn on, it would wait for about 30-40 seconds before an image appeared on the screen.
        Initially, I updated from windows to Intel Management Engine 11.8 Firmware, restarted, everything was fine.
        Then I updated the bios, also from windows, to the last vs, vs 46. It restarted, those lines with bios update progress appeared, restarted and that's it, since then...

        Hello everyone,

        First, the data in brief:
        Manufacturer: Lenovo
        Model: ThinkPad L15 G3 21C3-0016GE
        motherboard: LG4 LT5 ADL RT UMA MB 8L - 448.0PZ26.0011

        So far I've been a silent reader, but now I need your help

        I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
        I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...

        Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
        by akwky
        Hi!
        Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

        Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...
