Installing a Battery

Your computer comes with a lithium-ion or nickel-metal hydride (NiMH) battery
installed in the battery bay. The battery provides power to your computer when AC
power is not available.
NOTICE: These batteries are designed to work with Dell Inspiron 3800
computers only. To avoid damaging the batteries or the computer, do not
use the batteries with other computers, and do not use a battery from
another computer.
NOTE: You can also install a second battery in the media bay. If the computer already
contains a battery in the battery bay and you are installing a second battery, see
"Installing a Second Battery," found later in this chapter.
To install a battery in the battery bay, perform the following steps:
1. Save and close any open files, exit any open application programs, and shut down
the computer.
2. If the computer is docked, undock it. For instructions, see your Advanced Port
Replicator User's Guide.
NOTICE: To avoid data loss, do not replace a battery while the computer is
turned on unless the computer is connected to an electrical outlet or a
second battery is installed.
3. If the media bay contains a battery, go to step 5. Otherwise, continue to step 4.
4. If the only battery in the computer is in the battery bay and that is the battery you
want to replace, connect the computer to an electrical outlet and then preserve
your data in one of the following ways:
•
Use standby mode.
Place the computer in standby mode by pressing <Fn><Esc> (or by press-
ing <Scroll Lock><Esc> on an external keyboard if the External Hot Key
option is enabled in the System Setup program). Then shut down the
computer.
•
Use save-to-disk suspend mode.
Place the computer in save-to-disk suspend mode by pressing <Fn><a>
(or <Fn><q> on a French keyboard).
When the green power indicator turns off, continue to step 5.
5. Remove the battery from the battery bay.
a. Close the computer display and turn the computer over (see Figure 2-4).
b. Slide the battery bay latch toward the unlock icon.
c. Hold the latch in this position with one hand while pulling the battery out of
the bay with your other hand (see Figure 2-5).
