Clearing or Changing Hard Disk Drive Passwords

This section describes how to clear or change User and Master hard disk drive passwords. The procedures for clearing the passwords are as follows:

•User Hard Disk Drive Passwords:

If a valid User hard disk drive password has been entered and the user wishes to change or delete the password, the user must first enter the existing User hard disk drive password in BIOS Setup for security confirmation.

To delete an existing User hard disk drive password, the user can enter a blank password for the new password.

•Master Hard Disk Drive Passwords:

If a valid Master hard disk drive password has been entered and the user wishes to change or delete the password, the user must first enter the existing Master hard disk drive password in BIOS Setup for security confirmation.

To delete an existing Master hard disk drive password, the user can enter a blank password for the new password.

Replacing the Battery

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.

When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 28 on page 66 shows the location of the battery.

CAUTION

Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where possible. Disposal of used batteries must be in accordance with local environmental regulations.

PRECAUTION

Risque d'explosion si la pile usagée est remplacée par une pile de type incorrect. Les piles usagées doivent être recyclées dans la mesure du possible. La mise au rebut des piles usagées doit respecter les réglementations locales en vigueur en matière de protection de l'environnement.

FORHOLDSREGEL

Eksplosionsfare, hvis batteriet erstattes med et batteri af en forkert type. Batterier bør om muligt genbruges. Bortskaffelse af brugte batterier bør foregå i overensstemmelse med gældende miljølovgivning.
