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.
What should I do if my battery pack rapidly wears out?
Using your computer with the active wireless functionalities consumes more battery power.
If you do not intend to use the Bluetooth functionality while both Wireless LAN and Bluetooth functionalities are active,
follow these steps to disconnect your Bluetooth device.
1 Double-click on the taskbar to display the Wireless Device Switch window.
2 Cancel the Enable Bluetooth Device option.
3 Click OK.
If you do not use both Wireless LAN and Bluetooth functionalities, turn off the WIRELESS switch.
