yes..before that, transfer the DMI information from your bios to the virgin one..
the bios from post # 3 is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

you have everything you need at post #3...

Hello,
I recently tried updating the BIOS on my Lenovo IdeaPad Flex 5 and after about 15 - 20 minutes of waiting and a few restarts, the screen was completely black. I tried a bunch of different recovery methods but none seemed to work. I managed to get a BIOS dump using the tools I had on hand, but after looking into what I had to do in order to keep device data like UUID, SN, MAC address etc. I was a little intimidated and feared I might mess up and irreversibly damage my board. Was hoping someone much more knowledgeable with these things could create a usable BIOS as I'm way out of my depth here.
Device Specs:
Model: Lenovo IdeaPad Flex 5 14ARE05
CPU: AMD Ryzen 5 4500U
SN: R91281DR
Board ID: LNVNB161216
P/N: 5B20S44391
I have both the BIOS dump from the board and the extracted CAP file from the latest Lenovo BIOS update version EECN44WW. I believe the original BIOS version on my machine was EECN33WW but I'm not 100% sure. Was hoping someone could rebuild/merge the NVRAM, PSP/SMU firmware, and Board-specific data with the BIOS in the CAP file. If anything else is needed don't hesitate to let me know. Thanks in advance for any help.

It says in the post I linked...
Win32diskimager: https://sourceforge.net/projects/win32diskimager/
You need a blank/empty USB drive, otherwise it will delete all data on it
The file by AHSAN TARIQ is meant to be flashed with a programmer directly to the BIOS chip
If you want the update.exe from Lenovo, earliest version available is EECN42WW https://download.lenovo.com/consumer...s/eecn42ww.exeLeave a comment:

If you have a BIOS backup before you flashed new BIOS, the DMI can be copied from original (corrupt) BIOS to a new BIOS, here are the offsets, use hex editor
Lenovo Flex 5-14ARE05 Laptop (ideapad) - Type 81X2
DMI B21000-B213FF
Win key B10000-B100BF
Otherwise if you don't have a backup of the corrupt BIOS try Golden Key USB to fill S/N, MTM, etc.

my laptop is lenovo flex 5 14ITL05
recently my power supply for this laptop developed a fault.
which caused a short in my usb c port -- verified with a new charger.
rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32... -

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....
