Thank you so much, I didn't have much hope but that password worked. I can finally access the BIOS.
I updated the BIOS a while ago and it was locked with a password I didn't set, and now I can finally access it.
How do you know that was the password?

I am working on a lenovo nm-a311 motherboard. It came with a short on the CPU_GFX_VIN line, repair change a capacitor and a mosfet. I have the problem that I prede with the battery but it does not activate the screen, then I put the charger and the screen is activated and it turns on normally. But it does not charge while it is on, only when it is turned off. When it goes into sleep mode and it is battery-only it does not reactivate, I must put the charger and then it reactivates. I have reviewed the lines to the EC with the PU301. But I have doubt with the line + 3VALW. Any ideas. thks.
