Notes on Using the Battery Pack
Before using the battery pack, read the following precautions for correct use.
About the battery pack
The supplied battery pack is designed specifically for your VAIO computer.
For your safety, only use the supplied battery pack or an optional battery pack
that is specified by Sony.
For safety reasons, battery charging may be suspended at higher or lower
temperatures.
The battery pack is not fully charged at the time of delivery.
While the battery pack is in use or being charged, heat builds up in the battery
pack. This is normal and is not cause for concern.
Do not use your VAIO computer without installing the battery pack as it may
cause the computer to malfunction.
About battery discharge
After battery charge, the battery pack will gradually discharge over time even
while not in use. If it is left unused for an extended period of time, the battery
power may be depleted. It is recommended that you recharge the battery pack
before use.
About battery life
Battery life varies depending on usage and settings.
About battery deterioration and replacement
The battery pack is consumable. The capacity gradually declines through
repeated cycles of recharging and discharging. As a result, the battery life
becomes short even if it is fully charged and eventually the battery pack
reaches the end of its life.
If the battery pack quickly runs out of power after being fully charged or it has
reached the end of its life, replace it with a new one.
When the battery pack is running out of power
If the battery pack runs out and your VAIO computer is not plugged in, power will
be cut off and any data you are working on will be lost.
While your VAIO computer is running on battery power, save data frequently.
