Can my computer enter Hibernate mode while running on battery power?
Your computer can enter Hibernate mode while running on 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
for information on
how you can manually activate Hibernate mode.
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 such a 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.
