Lenovo ThinkPad L15 BIOS Request

[Jonh “Jonathan” JP]

Hello, I have a Lenovo ThinkPad L15 Gen 3
type 21C7-001FMX s/n - pw-032x94

I need some help, what do I need to reprogramming this type of bios with? Correct me if I am wrong, but I have the CH341A but it does not support it.

thank you in advance!

I just realized that it is possible to do it with CH341A, reading with MX25U25635F. Thanks to the comments above

Hello,

I am revisiting one of my first laptops I began working on and broke the bios chip (rookie mistake...). I unfortunately was never able to get any data off of the chip since it broke on removal. I have since gotten a replacement. Would anyone be able to provide a clean bios for this laptop? I am also a bit confused in regards to the bios chip. It is a GigaDevice 25R256DYIG. I can't locate it on any of the programmers I use. Info below. Thank you for any help!

Model: 20X4SBDN00
Serial # PF3WEDZR
Board: HL4A0/HL5A0 NM-D271 Rev: 3.0

I have tried using online bins, but every one I use is ineffective. PC wont turn on at all, just blinks 3 times when plugged in. Due to not finding the chip in the programmers, I used CH341A Programmer and it came up as a W25Q256FV. I have been trying to use that but no luck. Any help please is appreciated!

Issue has been resolved! I was able to find the chip using NeoProgrammer. I also used a old clean bin that I had from a previous L15 and the laptop booted into self heal and is working!

Hello, unfortunately, the BIOS is asking me for the password again.
The chip was also erased before I could write anything to it.
After flashing the new file, the BIOS repaired itself, rebooted, and had a password again.
I really thank you for your help.

Hello my friends, when I plug in the charger of my Lenovo Thinkpad Thinkpad L15 GEN2, the notebook starts up directly. There is music during startup but I cannot get an image. Can you edit my BIOS? Thank you.

Hello, I have a laptop whose BIOS update failed. It has an MX25L25673GZ41-10G BIOS chip. It's an MSI Katana GF66 12UD. I accidentally deleted the BIOS file from the chip and didn't make a backup. How can I revive it?
The laptop only blinks the power LED, but nothing else happens; there's no image and the fans don't spin. I tried flashing the original file from the MSI website using the CH341A, but that didn't work either.
