The laptop/PC serial number must be posted with all bios requests. Anyway,you can try and unlock it yourself using the Lenovo Autopatcher ,you`ll find it if you read the bios guides

Hello everyone,
I have a T470 type 20HE that does not start: only the green led of the "on/off" button flashes 3 times when you plug the charger and that's all, even the fan does not turn.
Do you think it comes from the BIOS and, if so, is it possible to fix it?
Thank you for your help and cordiallyComment

Lenovo t470 20jn-sv2vnoe PF1Q63B0
Hello, I was flashing the bios but now the machine does not come, the battery indicator turns orange when charge is plugged in. As soon as it plugged by charger or battery the power button and escape blinks once then fade out Sometime it blinks 3 timess . With the back case off i can see the fan spins a little then top, but once i press the button it spins a little then stop and repeat for a while until stops. I have attached the bios dump. I had read the chip next to the cmos battery (25q80jvsiq) then i realize that it wasn't the bios. as the bios is next the memory slot. By doing that could i have corrupted u15 25q80jvsiq, could that be the reason why it wont post? i saw a post saying don't touch the 25q80jvsiq but it was little too late. I jumped the gun. Is 25q80jvsiq considered the EC? The bios chip on the board is win bond 25Q128JVSQ - 1911 any help would be appreciated.

Hello!
I have a T470 type 20HE-S7DW00, SN: PF-11NE29
Please, I need this BIOS too!
I did not find in the forum, a suitable and functional BIOS for this 20HE model.
I haven't made a BIOS backup yet, until I see if I find something that works.Comment

Thank you very much, hoaca388, for the answer and support!
I don't know if your 20JV model is compatible with 20HE. I compared the two files a little bit and they have a lot of differences in the lines of code. But I will still try your file in the next few days and I will come back with an feedback.Comment

Hello! hoaca388 when I want to load the file in XGecuPro, it gives me an error that the file is not good or missing.Comment

After a few hours of work and attempts, I succeeded to bring the laptop back to life, with the original bios fixed.
I read the dump after starting the laptop, to backup it this new generated and repaired file, and for to be able to post it here for other users, too.Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder...
