[Q&A] [HELP WANTED] Mi Notebook Air 13.3 (A03) BIOS Password Reset

2020-11-11 01:20:09

Hello,

I got in late 2016 a USED 1st gen Mi Notebook Air 13.3" with the i5-6200U CPU and 8GB RAM. Everything ran OK with exception a faulty CPU fan.

Right now I'm facing an issue with BIOS. It seems that either the previous owner or Xiaomi has set a BIOS password and I can't enter BIOS for something I need to change.

I need to reset the password. Is there a way to do such a thing?

What I've tried so far with no success:

  • remove the battery for a few minutes
  • try to power-on without battery on AC power
  • left overnight without battery
  • hold the power-button while attaching either AC power or battery


Please help, I don't want to throw away a good working laptop.

I managed to successfully reset bios password on my mi Air 13.3. what worked for me it's shorting pins 5 and 6 of bios chip. I had to repeat this few times and sometimes the laptop turned on without showing anything on screen, but it worked after a while and password was gone. Information based on this article:
