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:
1 If the weight saver or the floppy disk drive is in the multi-purpose bay (1), remove it (see (page 40)).
2 Insert the battery pack (2) into the multi-purpose bay.
The battery 2 indicator light turns on.
3 Attach the weight saver (3) to the computer to stabilize the battery pack.
4 Slide the eject lever on the bottom of the weight saver towards 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.
