Measuring the Remaining Battery Charge

the battery icon in the system tray of the Taskbar to con rm the

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.
When not using the battery for a long time, store the battery after
charging it to 30-40% of its capacity. This extends the battery life
time.
Extending the Battery Usage Time
Decreasing the LCD Brightness
Press the + keys on the keyboard to decrease the LCD
brightness to extend the battery usage time.
Using the power management program
This program helps you use the battery more e ciently
and supports the power mode optimized for the operating
environment.
