Charging the battery pack
To charge the battery pack, proceed as follows:
1 Connect the AC adapter to the computer.
2 Insert the battery pack.
The computer automatically charges the battery (1) (the battery indicator (2) light flashes in a double
blink pattern as the battery charges). When the battery is 85% full, the battery indicator light turns off.
This process takes two hours when the system is off/on. To charge the battery completely, continue
charging for an additional hour.
✍ When the battery is running out of power, both the battery and power indicators blink.
Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the
computer.
If the battery level falls below 10%, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully
charged battery.
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.
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.
