!
The shape of the plug varies depending on the AC adapter.
10
Using your VAIO computer
✍
Use your computer only with the supplied AC adapter.
✍
To disconnect your computer completely from mains voltage, unplug the AC adapter.
✍
Make sure that the socket outlet is easily accessible.
✍
If you do not use the AC adapter for a long period of time, put your computer into Hibernate mode. This power saving mode saves you the time of shutting down in the normal way.

Using the battery pack

The battery pack supplied with your computer is not fully charged at the time of purchase.

Attaching the battery pack

To attach the battery pack, proceed as follows:
1 Slide the LOCK lever (1) on the top of your computer in the reverse direction of the arrow.
