Using your VAIO computer
✍
When the battery is running out of power, both the battery and power indicators blink.
✍
Keep the battery pack attached to 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 attach 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.
✍
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. If the battery wears out when your computer enters Standby mode, you will
lose any unsaved data. Going back to the previous work state is impossible. To avoid loss of data, you should save your data
frequently.
✍
When the computer is directly connected to AC power and has a battery pack attached, it uses power from the AC outlet.
