Can my computer enter Hibernate mode while using battery power?

Your computer can enter Hibernate mode while using battery power, but some software programs and peripheral devices
prevent the system from entering Hibernate mode. If you are using a program that prevents the system from entering
Hibernate mode, save your data frequently to avoid losing data. See Using Hibernate Mode
how you can manually activate Hibernate mode.

Why doesn't my computer enter Hibernate mode?

You may first need to enable Hibernate mode. Follow these steps:
1 Click Start and then Control Panel.
2 Click Performance and Maintenance.
3 Click Power Options.
The Power Options Properties window appears.
4 Select the Hibernate tab.
5 Click to check the box next to Enable hibernation.
Why doesn't the charge indicator light go out when it seems the computer and the AC
adapter have been connected for long enough?
When the temperature is below approximately 59°F (15°C), the battery pack (VGP-BPS15 or VGP-BPL15) is designed to
charge to approximately 80% capacity. In this case, the charge indicator light remains on while the computer is connected to
the AC adapter. However, this is normal and does not indicate a malfunction.
