Drivelock HDD and power-on password

[Rosli]

I encounter 2 problems once I turn-on my Compaq Presario 2800:
1.Error message "Drivelock HDD By Password ", once I enter "D" as the password the next message appears, that's "Power-on Password". I got stuck, I do not have the password. What shall I do to get the notebook running? For your information the unit has not been used for more than one year

You can try in this way...
When the hard disk password is set the same as the power-on password:
Remove the password by following the procedure below. This operation removes both the hard disk password and the power on password.
You must remove your password at the password prompt that appears when you turn on the computer. To remove the password, at the prompt: Enter your current password, press the Spacebar and then press Enter.
When the hard disk password and the power-on password are different, or a power-on password has not been
set:
1. Turn off the computer and wait at least 5 seconds: then turn it on.
2. If you have set the power-on password, type it; then press Enter.
3. When the hard disk password prompt appears, type your current password, press the Spacebar, and then press Enter.

if don't work, you can Clearing CMOS...
will disable the password and allow the computer to boot.
TURN OFF PC and disconnect voltage.

Search on mother board manual where is the "clear cmos" and change jumper for few seconds. Then rechange jumper in initial point position. This restore Bios default
