Optimizing battery use of VAIO computers containing PowerPanel software

The Power Options Properties window appears.

2Click the Power Schemes tab, and select Automatic Profile Selection from the Power schemes list.

3Click OK.

For more information about using the PowerPanel software, refer to the Using PowerPanel utility section of your VAIO® notebook User Guide. To access the User Guide, click Start on the Windows taskbar, click Help and Support, and click VAIO User Guide.

Using the battery

Depending upon your VAIO® notebook computer model, your computer can use one or two batteries to provide power when AC power is not available. Spare batteries are available for purchase separately. The battery supplied with your computer is not fully charged at the time of purchase.

For safety reasons, some VAIO® notebook computer models include utility software that verifies that the battery in use is a genuine Sony battery. If a third-party battery is detected, the following pop-up message appears:

This battery cannot be used with your computer. Please use only genuine Sony batteries compatible with this computer. Click ‘OK’ to put your computer into Hibernate mode. When your computer hibernates, remove the battery, and insert a genuine Sony battery.

If you encounter this message and you are using a third-party battery, follow the on-screen instruction to replace the third-party battery with a genuine Sony battery. In some situations, this message may appear when you are using a genuine Sony battery if the battery is not firmly connected to the computer. Try removing and reinserting the battery.
