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 °C 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 22 on page 42 shows the location of the battery.
CAUTION
You will have the risk of explosion if the battery is replaced incorrectly.
Batteries should be recycled if possible. Disposal of used batteries must be in
accordance with local environmental regulations.
To replace the battery, follow these steps:
1.
Observe the precautions in "Before You Begin" (see page 18).
2.
Turn off all peripheral devices connected to the computer. Disconnect the computer’s power
cord from the AC power source (wall outlet or power adapter).
3.
Remove the computer cover.
4.
Locate the battery on the board (see Figure 22).
5.
Disconnect the battery wires from the connector (Figure 22, A) and remove the battery (Figure
22, B) from the back of the I/O stack
6.
To install the new battery, remove the paper backing (Figure 22, C) from the battery adhesive
pad, attach the battery to the I/O stack, and connect the wires (Figure 22, E) to the server board.
7.
Replace the computer cover.
