Thanks, Hoaca388 and Shiyab for the files.
I tried Hoaca388's file and it worked. I have display.
However, I lost DMI info (S/N, Model #, UUID and Windows Key) as shown in the picture.
I tried using the Lenovo Uone tool to write the DMI info but I get an error "Locate protocol with LenovoEeprom, status [e]"
"Eeprom fail when reading or writing data."
Is there a way to fix the DMI tool error? I'd like to try that first if possible since I'd prefer not to desolder the BIOS chip again.
shiyab does your file retain the DMI information so I should go ahead and try that if I'm unable to write the DMI info with the tool?
Thanks, again for the help.

Thanks, qayyum786. I made a rookie mistake in my haste to flash the BIOS. I forgot the battery was still when I was placing heat tapes on resistors and capacitors around the BIOS chip to prepare for desoldering the BIOS chip. I ended up shorting the BIOS chip (it burned). I replaced it with the same part number from a donor board and flashed your bin file but now there's no power. The laptop doesn't turn on anymore. I tried with battery only, power adapter only, and battery with power adapter with the same results, no power. I guess I might have damaged other components besides the BIOS chip
This is the end of this repair for me.
Thanks, everyone for all the help.
Cheers!Comment

now you have everything you need at post #3...transfer DMI AND KEYWIN yourself...
the bios from post # 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...

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.... -
Hi everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI
