How to disable Hard drive password


Did you clear your BIOS to rid yourself of the bios password first? Just making sure you are really looking for the hdd password (which you set while setting the BIOS password I assume) There are some tools out there to help you remove/rest the hdd password but lets be sure that's what you need to do first. Be warned, the tools don't always work and unless you remember the password you might be looking at complete data loss and a new hard drive.

How do I delete or reset a new system password, and a HDD password so that I can set a administrator password on a optiplex 390 i5 window 7.?


If you do not have the current passwords, it's going to be a bit of a problem. The BIOS password mostly. Contact Dell Support: http://www.dell.com/us/business/p/optiplex-390/pd Perhaps they will give you a one-time BIOS password. If it's a login password, you could try a Full Factory Recovery. If someone put the passwords in , I would ask them, that's the easiest way.

My dell desktop asking for a password


If you want to create a new Basic Input/Output System (BIOS) password on a Dell Optiplex 745, reset the password. Resetting the password also applies if you want to remove an existing BIOS password. BIOS passwords are used to add an additional level of security to your machine. Without the correct BIOS password, your Dell Optiplex 745 will not complete the boot process. The password can be reset whether you know your current password or not.

Turn off your Dell Optiplex 745. Start the computer. Press "F2" the moment the Dell logo appears on the screen. You will only have two to three seconds to press the key. Enter your BIOS password. Navigate to the "Exit" screen. Select the "BIOS Password" setting. Enter your BIOS password and a new password if desired. Do not enter anything in the "New Password" box if you want to remove the BIOS password completely. Press "Enter" to save your password settings. Reset Forgotten Passwords Turn off your Dell Optiplex 745 and remove the power cord from the computer. Disconnect any external hardware and cables. Slide the release latch located on the back of your Optiplex 745. Lift the cover as you slide the latch. Hold the cover firmly and pivot it back on the hinges. Remove the cover from the hinges. Find the "PSWD" jumper on the motherboard. This is a two-pin jumper and should be clearly labeled. Use a flashlight and magnifying glass if you have trouble locating it. Remove the jumper from the motherboard. Replace the cover and slide it into place until the latch snaps into place. Reconnect the power cable and restart your computer. Shut down the computer after it has completely restarted. Disconnect all cables and remove the cover again. Replace the PSWD jumper. Replace the cover. Reconnect all cables and restart your computer.

Bios default password


The BIOS default password is just blank, and it is not asked.

When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.

To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
