n 25 N

Keep the battery pack in your computer while it is directly connected to AC power. The battery pack continues to charge while you are using the computer. When the battery pack is running out of power and both the charge and power indicator lights blink, you should either connect the AC adapter to recharge the battery pack or shut down your computer and install a fully charged battery pack. Your computer is supplied with a lithium ion battery pack and can be recharged any time. Charging a partially discharged battery pack does not affect the life of battery. You can extend the life of your battery pack if you enable the battery care function of the Battery Charge Functions with the VAIO Control Center. While some software applications or peripheral devices are in use, your computer may not enter Hibernate mode even when the remaining battery life becomes short. To avoid loss of data while the computer is running on the battery, you should save your data frequently and manually activate a power management mode, such as Sleep or Hibernate. If the battery pack runs out of power while the computer is in Sleep mode, you will lose all unsaved data. Going back to the previous work state is impossible. To avoid loss of data, you should save your data frequently.

Precautions > Using the Battery Pack

n 110 N

Battery life is shorter in a cold environment. This is due to decreased battery efficiency at low temperatures. Charge battery packs at temperatures between 50F to 86F (10C to 30C). Lower temperatures require longer charging time. Do not charge the battery pack in any way other than as described in this user guide or as designated by Sony in writing. 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. You do not need to discharge the battery pack before recharging. If the battery pack quickly runs out of power after being fully charged, it may be reaching the end of its life and should be replaced.
