BIOS Power On Authentication Failed

HP Recommended
ProBook 450 G5
Microsoft Windows 10 (64-bit)

Hi Team,

I have ProBook 450 G5 with serial number [Private information removed].  My 11 year old boy he set Power On Authentication password for this laptop and he can't recall what actually is the password. Tried several times, but nothing works. It only shows select user as BIOS Administrator or POST Power-On Password.

Can anyone help me out with this?
