Related service information If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered. Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted. Power-on password: A power-on password (POP) protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be booted. Hard-disk password: There are two hard-disk passwords (HDPs): v User HDP-for the user v Master HDP-for the system administrator, who can use it to get access to the hard disk even if the user has changed the user HDP Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires two HDPs; the system administrator enters both in the same operation. The system administrator then provides the user HDP to the system user. Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be used for access to the hard disk drive. If no master HDP is available, Lenovo does not provide any services to reset either the user or the master HDP, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee. Supervisor password: A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration. Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee. How to remove the power-on password To remove a POP that you have forgotten, do the following: (A) If no SVP has been set: 1. Turn off the computer. 2. Remove the battery pack. For how to remove the battery pack, see "1010 Battery pack" on page 57. 3. Remove the backup battery. For how to remove the backup battery, see "1100 Backup battery" on page 73. 4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed. 5. Reinstall the backup battery and the battery pack. (B) If an SVP has been set and is known by the servicer: 22 MT 2529, 2530, 2531, and 2532
