Using Battery Power
You can use one or two battery packs as a source of power. The second
battery pack inserts into the multipurpose bay on the right side of the
computer. (See “Using Power Saving Modes” on page 36.) Additional
battery packs are available as a separate option.
The battery pack that comes with your computer is not fully charged at
the time of purchase. Follow the steps below to insert and charge the
battery pack.
To insert the battery pack
1
Open the cover of the battery bay.
2
Insert the battery pack into the battery bay on the left side of the
computer.
3

✍
When attaching your computer to the port replicator, do not attempt to insert or remove the
battery pack. Lifting and turning the computer with a port replicator attached could cause a
temporary loss of power.
