"...bios Setups Administrator password.Why don't you know it?"Well that's the problem I am haveing at the present.With an HP DV4000.I don't no it eather.But only because.The person whom I perchused,this mechine from.Didn't no it eather."
If that person does not know a system access password - you must enter it to use the laptop at all - or a hard drive access password - you must enter it to access the hard drive - then the laptop IS PROBABLY STOLEN !
You don't forget a password you have to use every time you use the computer unless you have serious mental problems !
"I don't beleave it 2 B stollen.If I find it 2 be.I will gladly return it.2 its rightful owener."
Good luck, but whoever it was may be long gone, or will not take it back.
There are illegitimate ways of removing laptop access passwords, but the rules of this web site forbid us from telling you about those.
Removing passwords on modern laptops is difficult or impossible, unless you are the original owner and can prove it, or unless you are willing to spend money to have an expert remove the passwords, or you are willing to spend money to replace the mboard, and the hard drive if the hard drive is passworded.
If it's ONLY a password to access the bios Setup , if your problem is you can't boot the computer with a device because of the way the Boot Order or similar settings are set in the bios, on most brand name computers, there is a prompt that appears on the screen while booting "Press xxx to select boot device." or similar - you just press the stated key while that text is on the screen and select a device to boot from.
There are probably hundreds of Topics on this web site alone where someone wants to remove a bios set password from a laptop.
