    EDIT: What bios programmer are you using.
    When I install this bios in my notebook it asks me for a password to be able to enter the bios, they will know what it is, thank you ..

    Hello guys, hope your all fine!

    Need some help, i have one Lenovo ThinkPad T450s
    Board Model:
    AIMT1 NM-A301 REV 1.0

    Well, machine seems to power on, but only gives me a full black screen no backlight, no caps no num lock on internal or external keyboard.

    LID Switch seems ok, 3.3V and when i put magnet on him drops to 0V so it's fine.

    I talked with some people and all they say me BIOS Issue, i have original dump attached for anyone who could open it search for any error and fix the dump for me please.

    Thanks for all any questions please be free to post.

    Lenovo T450s BIOS Signature

    First thread. Anyway, I've modded my bios to replace the date/time menu with the advanced menu but now the T450s has 2x5 beeps at every cold and warm boot. I'm told this is because the signature needs to be modified. Is this possible on this laptop or not? I'm on the latest bios version 1.37

    I've been pointed in this direction reading all of this post:

    https://www.insanelymac.com/forum/to...eps-on-lenovo/

    But of course my BIOS is different and the steps need to be modified which I'm having trouble with. Anyone know what I'm after?

    I'm a bit reserved paying someone to do it because who knows what edits they'll make to the bios without my knowledge.

    Thanks

    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...
    The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

    Should I buy a Lenovo Thinkpad E495 with bios password?
    by RMDUiFT
    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.

    I have a few questions:

    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...

    Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
    by Wahaz
    Hello,

    I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
    So I thought it was a Bios problem.
    I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
