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 cordially
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. https://www.badcaps.net/filedata/fetch?id=3254155bios_backup.zip
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.

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.
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.

I'm new to flashing anything for Lenovo. What do you mean when you clean/clear the ME? How is that process done?
