Frequently asked questions
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 at all. If you are using a program that prevents the system from entering
Hibernate mode, save your data frequently. See
Using power saving modes for information on how you can manually
activate Hibernate mode.
When should I replace the battery?
If, after fully charging the battery, the battery power is still low, the battery may be reaching the end of its life and should
be replaced.
Why is the battery warm?
While the battery is in use or being discharged, the battery heats up. This is normal and is not cause for concern.
