LattePanda 3 Bios Locked

Recently, I've purchased LattePanda 3 on ebay and now found out that bios is password protected. 

When trying to boot board: 

1. Panda boot logo appear;

2. Blue text field with password appear;

Tried to remove CMOS battery in order to reset bios, but I assume it should not work on 3rd model.

Please let me know if there are solution to this.
