Troubleshooting Batteries
How do I know when the battery is charged?
To determine the remaining battery charge, see Displaying battery information.
When is the computer using AC power?
When the computer is directly connected to the AC adapter, it uses AC power, even if a battery is installed.
When should I recharge the battery?

When the battery level falls below 10 percent.
 When both the battery and power indicators blink.
 When you have not used the battery for a considerable amount of time.
Can my computer enter Hibernate mode while using battery power?
For some software programs and some peripheral devices, your computer may not enter Hibernate mode when the battery
life is low. To avoid loss of data when using battery power, you should save your data frequently and manually activate a
power management mode, such as Standby or Hibernate.
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.
