Turning On the Computer

To turn on the computer, open the computer display and press the power button
(see Figure 1-2).
NOTE: Do not dock the computer until it has been turned on and shut down at least
once.

Replacing the Battery

NOTICE: To avoid data loss, do not remove the battery while the computer
is turned on unless the computer is connected to an electrical outlet.
To replace a battery in the battery bay, perform the following steps (see Figure 1-3).
NOTES: If necessary, print these instructions for reference before proceeding.
Dell recommends that you turn the computer off before replacing the battery.
If you want to replace the battery while the computer is running, you must first
connect the computer to an electrical outlet or enter suspend (or standby) mode or
suspend-to-disk (S2D) mode. You cannot replace the battery while the computer is
running on battery power.
1. If the computer is docked, undock it. (See the documentation that came with
your docking device.)
NOTICE: If you choose to replace the battery with the computer in suspend
(or standby) mode, you have up to 2 minutes to complete the battery
replacement.
2. Preserve your data in one of the following ways:
•
Close all files and shut down the system.
•
Save all open files and then connect the computer to an electrical outlet or
put it into suspend (or standby) mode by pressing <Fn><Esc> (or you can
press <Scroll Lock><Esc> on an external keyboard if the External Hot Key
option is enabled in the system setup program).
3. Remove the battery from the battery bay.
Close the computer display and turn the computer over. Slide the battery bay
latch to the unlock position (see Figure 1-3), causing the battery to pop up slightly
on one side. While keeping the latch in the unlock position, pivot the battery up
and out of the bay. Release the latch.
