Should I be concerned that the installed battery pack is warm?
No, it is normal for the battery pack to be warm when it is powering your computer.

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 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 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.
