    Lenovo Z13 - 21D2000MUS -- BIOS Debug

    Hey all
    Does anyone know the key combo to unlock / show the debug BIOS on the Lenovo Z13. This model is the AMD chipset.

    I didn't post the BIOS as I hope there is a way to show the debug menu without a modded BIOS.

    Thanks!

      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....

      Acer Aspire 5920G - Requesting Modded BIOS (9600M GT) from .WPH for CH341A Flasher
      by EbrahimSiami
      Hello everyone,
      I need help with my Acer Aspire 5920G laptop. Its original GeForce 8600M GT graphics card failed, so I replaced it with an Nvidia GeForce 9600M GT MXM card.

      **Problem:** The laptop powers on, but there is no display (black screen) on either the internal LCD or external monitor. This indicates a BIOS compatibility issue with the new graphics card.

      **What I have tried so far:**
      1. I have my **original stock BIOS dump (1MB .BIN file)** from my laptop, which works and allows the laptop to power on normally (but no display with 9600M...

      Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
      by grimacelord
      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...

      Lenovo T480s, what's up with this Bios, modded boot logo, reflashed now bricked
      by q2v5
      Lenovo T480s
      Model 20L8-S3TE00
      Board ET481-U10
      Chip MX25L12873F

      Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.

      2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.

      The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...

      Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
      by jendkkd jeje
      So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

      I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
