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 Figure1-6).
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
