            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 ThinkStation P720 BIOS Request
            by HammyCheesy
            Hello all,

            I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."

            When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).

            Type: 30BB
            Model Number: S03600
            S/N: MJ07N68C

            Things I have tried:

            1. Reseated all components, pulled everything except for 2 RAM modules (1 per CPU)
            2. Attempted to boot with just a single CPU...

            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...

            by jbonavita
            Hi, my laptop wont boot at all
            With original bios no POST, only LED lights
            With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again

            A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
            B- If updated from 500LN version 203 to 300, the battery stops being recognized

            Things I tried

            1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

            Lenovo Yoga Slim 7 14APU8 Bios Request
            by beogeek
            I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

            Attached is the bios dump in the state I received it...
