Blue screen- enter administrator password

[Jurinho]

Hello !

Here it comes: every time I turn on my laptop I get a blue bar asking: Enter Administrator Password or Power On Password. I've checked other forums with this issue and the system disabled message I get is [i 67869314].i removed the CMOS battery but i didn't solve the problem.I will be glad i can find a solution here.
