• 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

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.

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.
