Re: YOGA CYG50 NM-A901 Bios Request
I don't think the problem is the bios if you sometimes have lines on the screen... check the first time... use an external monitor and if you have an image on the external monitor, the problem is the display, LVDS cable, video chipset, check the LVDS cable plugs, if the cable makes good contact with the plugs..Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

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... -
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... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello everyone,
I need a BIOS for the Thinkpad L13 Yoga Gen 4.
S/N: PW05KQH7
Type Number: 21FR-0005GE
A recent BIOS update from Lenovo has bricked the laptop.
Currently there is no charging light.
According to Lenovo's website, the BIOS version R26ET41W/EC R26HT28W (r26uj08w) has been withdrawn due to issues with the system failing to power on after the BIOS/EC update. -
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....
