1.2 Resetting the Computer

If the computer you are servicing has an unknown password, follow these steps to set a new password. These steps also clear CMOS:

1. Enter an incorrect password and press

enter.

2. Repeat step 1 two more times.

After the third entry of the incorrect password, the computer responds with a “System Disabled” message and provides an override password.

3. On another computer running Windows XP, download the unlock6.exe utility from the HP Channel Services Network (CSN) Web site at

http://www.hp.com/partners/csn. Copy the

unlock6.exe utility into the root directory (C:\ drive).

4. Access MS-DOS by clicking Start > All Programs > Accessories > Command Prompt.

5. Enter

unlock6 xxxxx 0, where “xxxxx” is the password

generated by the computer in step 2.

The computer responds with another system-generated password.

6. Enter the password generated in step 5 on the disabled computer to enter the system BIOS. In the BIOS, navigate to the Security tab and Administrator Password. Enter the password generated in step 5 as the current password. Enter a new password to change it.

7. The password has been reset and all CMOS settings have been cleared.
