Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the commandit should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.Code:
"innoextract 7wcn38ww.exe"
The trouble I'm having is that I'm not getting the newly... -
Hi everyone,
Iām looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575

Hi,
first of all my apologies for my English (I don't speak it very well, I am French).
I am trying to troubleshoot a lenovo ideapad 5 15alc05 ryzen 7 that boots but remains in black screen.
I would like to know if anyone knows how to extract the .bin of bios from the exe published on the lenovo site. I have found several information on the internet but they don't work in my case. I think it's because it's an amd.
I found some dump on the internet but I don't really trust it. I would like to make a clean bis from the official Lenovo file...
