Serial: PF3A60HW
Model name: Legion 5 Pro-16ACH6H
Main Board: NM-D562 Rev:3
Winbond: 74M12JWS1Q, 25Q16JWN1Q

When I opened the PC I saw that there are two chips that say Winbond, do I have to install the BIOS on both? Or is there a thread that explains how to flash a Legion 5 Pro-16ACH6H?

Will the ch341a programmer work for my PC? I have read in other threads that they use it for the normal Lenovo Legion 5, but I don't know if it will work for the pro...

Hi, I've been reading the forum and I know that before I ask my question I need to give all the necessary information, so before I ask my full question could you tell me how I can find the following data:

Serial: PF39977K
Model name: Legion 5 15ACH6H
Main Board: NM-D562 Rev:3
BIOS: 74M12JWS1Q (W25Q128FW), (UB3, 16MB)
BIOS : W25Q16DW (UG10, 2MB)

This is an example of what I saw, it's not from my PC, but I would like to know how I can find that data on my PC​
