Lenovo M800Z bios request
Hi, I tried every bios I could find on the internet, including the official one, but none of them works. Can anyone help me with that?

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.... -
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... -
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
Some issues
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... -
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... -
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,...10-11-2024, 03:12 PM
