HP system disabled A [4DDA5510] Enter Administrator password / Power on Password

[entro]

Please help

I had my working HP admin / power on password, i wanted to remove it, i logged in to my bios, went to admin password which was set to (SET), i clicked , this came up,

ENTER CURRENT PASSWORD: [ I entered my current password ]
ENTER NEW PASSWORD: [ I just typed Enter to left it blank ]
RE-ENTER NEW PASSWORD: [ I just re-typed Enter to left it blank ]

 I entered my working password and pressed enter and enter again on new password, then next to admin password, it changed to (CLEAR),

i reset and went to log in assuming that i wouldnt come up or worst i would have to press enter twice but i am shut out. i get error message 

A [4DDA5510]

i have tried everything - Please save me.
