Configuring the System Board
The system board contains two configuration jumpers that provide three
modes of operation: Normal mode, Clear Password mode, and BIOS
Recovery mode.
Normal mode allows normal access to the BIOS Setup Utility. The Central
Processing Unit (CPU) input clock is forced to remain at 66 MHz (fast
mode), and the Basic Input/Output System (BIOS) uses the User CMOS
settings (as opposed to the System CMOS settings). The CMOS and
NVRAM settings are only cleared if the checksum test returns false.
Access to specific setup fields is controlled by a supervisor password or
user password.
Clear Password mode removes the password that is stored in CMOS.
BIOS Recovery mode sets the CPU input clock to 66 MHz (fast mode) and
attempts to perform a blind BIOS update.
1 Remove the side panel (see “Removing the Left Side Panel” on
page 22).
2 Remove the bottom panel (see “Removing the Bottom Panel” on
page 23).
✍
The configuration jumpers should never need changing unless otherwise directed by a
technical support or service technician.

Replacing the Lithium Battery
You may need to replace the lithium battery if your computer consistently
loses the date or time settings after turning it off. The lithium battery has
a typical life of three years, after which the battery may be too weak to
power the CMOS memory.
1 Reboot your computer by selecting Shut Down... from the Start
menu, and then selecting Restart the computer.
2 If the error message “Error: Check date and time settings”appears
during the reboot sequence, press F3, then press F2 during the reboot
process to access the BIOS Setup Utility. Otherwise it is not necessary
to replace the battery at this time, and you can skip all remaining
steps.
3 Compare all the BIOS options to their default settings (see “BIOS
Setup Options” on page 73). Make a list of all the BIOS options that
are different from their default values. You will refer to this list when
you restore the BIOS settings later.
4 Press ESC, then select Exit from the main menu using the right arrow
key. The Exit Discarding Changes is automatically selected (it is the
first item in the list).
5 Press Enter, type N when prompted to save, then press Enter to exit
the BIOS Setup Utility.
6 Turn off the computer and unplug the power cord.
7 Remove the left side panel (see “Removing the Left Side Panel” on
page 22).
8 Remove the bottom panel (see “Removing the Bottom Panel” on
page 23).
! When you remove the lithium battery, all values stored in the CMOS memory
(BIOS setup values and Plug and Play values) may be lost. Although the
computer can hold the charge for a short time while replacing the battery, it
is safer to assume that the settings will be lost. When the values are lost, the
BIOS values revert to their factory-default settings (see “Accessing the BIOS
Setup Utility” on page 16).
Do not handle damaged or leaking batteries.
The lithium battery may explode if mistreated. Do not disassemble it or
dispose of it in fire.
VAIO MicroTower System Reference

About User and Supervisor Passwords
The system allows you to specify up to two passwords (a User password
and a Supervisor password) in the BIOS Setup Utility. The User password
is required; the Supervisor password is optional.
Access to the BIOS Setup Utility depends on which passwords were
previously set, as indicated next.
If you set these passwords... ...the following passwords are required:
User password only User password is required at bootup.
Supervisor password only No password is required at bootup.
Supervisor password is required by most
setup options.
Both passwords User password is required at bootup.
Supervisor password is required by most
setup options.
Miscellaneous Technical Information
91
Beep Code Error Messages
During a normal bootup, a single short beep signifies that the system is
OK. Other beep patterns signify errors. The number of beeps indicates the
specific error that occurred.
The Sony Online Support technical representative will need to know how
many beeps your system produces if there is an error, so be sure to count
the number of beeps before calling for support.
