Using your notebook
24
The battery pack supplied with your computer is a lithium ion battery and can be recharged any time. Charging a partially discharged battery does
not affect battery life.
The battery indicator light is on while you use the battery pack as a power source. When the battery life is nearly depleted, both the battery and power
indicators start flashing.
For some software applications and some peripheral devices, your computer may not enter
Hibernate
mode even when battery life is low. To avoid
loss of data when using battery power, you should save your data frequently and manually activate a power management mode, such as
Standby
or
Hibernate
.
When the computer is directly connected to AC power and has a battery pack inserted in the battery bay, it uses power from the AC outlet.
Removing the battery pack
To remove the battery pack, proceed as follows:
1
Turn off the computer.
2
Open the cover of the battery bay.
3
Pull out the battery pack.
4
Close the cover of the battery bay.
✍
You may lose data if you remove the battery pack while the computer is on
and not connected to the AC adapter or if you remove the battery while the
computer is in
Standby
mode.
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.
