As soon as you power up your system, repeatedly tap F8 until another screen pops up. Select safe mode or safe mode with networking.
Choose guest once booted.
click start and then control panel.
Then user accounts .
Then add or remove user accounts
Then create new account.
Once account set up, set as administrator.
Reboot your system and start as normal.
Choose the user you created and log in with that.
You can then delete the other administrator account you mentioned.

Hope this helps and please rate thanks

How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

    Sorry to say it, but both of the other solutions will NOT work. The screen you have is the main Admin BIOS password screen. You cannot Remove the CMOS battery in a Dell D620 to clear it, it doesn't work. It is stored in the Eeprom chip.
    Your master password for that Service Tag = hbphehtl

    Please note that it needs to entered as it shows ALL in lower case HBPHEHTL
    Then, Type in the password on password request, hold CTRL and press the Enter key, this will clear all bios passwords.

Pls i want to unkock my dell latitude d620 Administrator password


you forgot to tell us what password.
Is it a bios password or windows password?


For Windows Password, As far as I know , there are two main methods to solve the windows password problem as follows:

1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel - User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

2th Method:
Windows password Recovery software:
for example: Any Windows Password Reset 7 . It is easy and convenient to use.
http://www.windowspasswordreset.net



For Bios Password, also two methods.

1st method . Open you computer box and Discharge to the Board manually

2st method . use BIOS/CMOS Password Recovery Tool

Hope it help to you.

I have a Dell Latitude C800 and i cant get past the power-on BIOS password. Can you please help?


You can get the master password for your Dell by calling Dell Technical Support at (800)624-9896.
Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Latitude.
If you were not the original owner of the Latitude, Dell will transfer registration of the used Latitude from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.
To transfer the registration of a used Dell Latitude, fill out the Transfer of Ownership form on Dell's web site.
