Using the second battery pack

You can purchase a second rechargeable battery pack. With two battery packs, you can extend the time you use your computer with battery power. When using two battery packs, the battery pack you insert first, charges first. The battery pack you insert second, charges when the first battery pack is 85 percent full. You can monitor which battery pack is charging by observing the battery indicator lights.

Inserting the second battery pack

To insert a second battery pack, proceed as follows:

1If the weight saver or the optical disc drive is in the multi-purpose bay (1), remove it.

2Insert the battery pack (2) into the multi-purpose bay. The battery 2 indicator light turns on.

3Attach the weight saver (3) to the computer to stabilize the battery pack.

4Slide the eject lever on the bottom of the weight saver toward the front of the computer to lock it.

If you attach two battery packs, you can remove one of them without shutting down the computer. When removing one battery pack, make sure that the other battery pack indicator is on. If the indicator of the battery pack you are going to remove is on, right-click the battery icon in the system tray and click the Switch Battery option.
