    Lenovo G50-80 (80L0) USB bios recovery

    Hello!

    Laptop is old Lenovo G50-80. It wont boot, cpufan works, there are no picture in the screen or TV with HDMI-cable.
    Maybe bios is corrupted?
    I have tried many operation to flash bios. If I press and hold long time Fn+R, the USB-stick blinks.

    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,...

    Summary of BIOS Whitelist Removal Problem


    Problem:
    I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
    Initial Findings:

    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....

    Lenovo Legion Y540 – Need help repairing BIOS after bad downgrade
    by gestalt.exe
    Hi everyone,

    My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
    Laptop stopped booting entirely.

    I used a CH341A programmer to dump the corrupted 16MB BIOS.
    i then attempted the following:
    1. Downloaded stock BIOS BHCN39WW from Lenovo
    2. Trimmed it to 16MB
    3. Extracted the BIOS region from the corrupted dump
    4. Extracted the BIOS region from the stock 39WW
    5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
    6. Injected back my LDGB / DMI

    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...
