Thank you, no need to reply. After I wrote, I saw the link to extract the BIOS and copy the DMI. I successfully completed the steps and the laptop came to life. Have a nice day! ...

Hello! I would like to ask for help because I am completely stuck with this machine. The battery on the machine ran out during the update and since then only the power button LED has been blinking. I have tried several BIOSes from the site. With the factory e8cn36ww.bin, the Lenovo logo came up once, but never again. I would like help in creating a clean BIOS. I have attached the original BIOS dump. Thank you for your help!​
Machine type: Lenovo Ideapad 3 15ADA05 (81W1)
Serial number: PF29E61X...
