Samsung NX30 ユーザーズマニュアル

Using the battery
The battery has an expendable supply, so when you use it for a long time, the 
capacity/battery life is shortened. If the battery life is reduced to under half of 
the initial time, we recommend that you purchase a new battery to use.

Battery Warning
You will hear an alarm when the remaining battery charge is under 10%. 
Connect the power cable or turn off the computer and install a fully charged 
battery.
When the remaining battery charge is under 3%, the computer automatically 
saves current work and turns off. This may be different according to the 
settings in Control Panel > Performance and Maintenance > Power 
Options > Alarms tab.

Calibrating your battery once a month is one of the recommended methods of 
increasing your computer’s battery life. To calibrate the battery complete the following 
steps:

Calibration Notes:
You should start the battery calibration process with a fully charged battery, 
battery status LED is green. However, the power meter may not show 100%. 
Before you commence the battery calibration process you should fully charge, 
then fully discharge and finally fully recharge the battery again.

1. Disconnect the AC power adapter after turning off the system.
