Battery Usage Time Information A battery is an expendable supply, so when using it over a long time, the capacity/battery life is shortened. If the battery life is reduced to under half of its initial time, we recommend purchasing a new battery. For long periods of not using the battery, keep the battery after discharging it. This extends the battery life time. Battery Warning  You will hear an alarm when the remaining battery charge reaches below 10%. In this case, connect the AC adapter or turn off the computer and install a fully charged battery.  If the battery residual amount is 3~5%, the computer automatically shuts down after saving the data. The battery residual amount may vary depending on the computer model. 179
