Replacing The System Battery - Dell OptiPlex GXi Reference And Installation Manual

11. If necessary, change the microprocessor speed
jumper setting (see Figure 5-7 to locate system
board jumpers).
The microprocessor speed jumper should be set for
the installed microprocessor's rated internal speed.
For example, for a 166-megahertz (MHz) Intel Pen-
tium processor, a jumper plug should be installed on
the pins labeled "166." (See "Jumpers" in Chapter 5
for more information.)
12. Replace the computer cover; reconnect your com-
puter and peripherals to their power sources, and
turn them on.
As the system boots, it detects the presence of the
new microprocessor and automatically changes the
system configuration information in the System
Setup program.
13. Enter the System Setup program, and confirm
that the
MICROPROCESSOR
identifies the installed microprocessor.
See Chapter 2, "Using the System Setup Program."
14. Run the Dell diagnostics to verify that the new
microprocessor is operating correctly.
See your Diagnostics and Troubleshooting Guide for
information on running the diskette-based diagnostics
and troubleshooting any problems that may occur.

eplacing the System Battery
A 3.0-V CR2032 coin-cell battery installed on the system
board maintains system configuration, date, and time
information in a special section of memory.
The operating life of the battery can extend up to ten
years. The battery may need replacing if an incorrect time
or date is displayed during the boot routine along with a
message such as:
Time-of-day not set — please run SETUP
program
or
Invalid configuration information —
please run SETUP program
or

category correctly
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether the battery needs replacing, reenter
the time and date through the System Setup program (not
through the MS-DOS time and date commands) and exit
the program properly to save the information. (See
Chapter 2, "Using the System Setup Program," for
instructions.) Turn off and disconnect your system from
alternating current (AC) power for a few hours; then
reconnect and turn on your system. Enter the System
Setup program. If the date and time are not correct in the
System Setup program, replace your battery.
You can operate your system without a battery; however,
without a battery, the system configuration information
maintained by the battery is erased if the system is turned
off or AC power is lost. In this case, you must enter the
System Setup program and reset the configuration
options.
WARNING: There is a danger of the new battery
exploding if it is incorrectly installed. Replace the
battery only with the same or equivalent type rec-
ommended by the manufacturer. Discard used
batteries according
instructions.
Use the following procedure to replace the system battery
with another CR2032 coin-cell battery:
1. If you have not already done so, make a copy of
your system configuration information in the Sys-
tem Setup program.
If the settings are lost while you are replacing the
battery, refer to your written or printed copy of the
system configuration information to restore the cor-
rect settings. See Chapter 2, "Using the System
Setup Program," for instructions.
2. Remove the computer cover according to the
instructions in "Removing the Computer Cover"
in Chapter 5.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.
