Using the power meter and power settings
The power meter is located on the Windows desktop. The power meter allows you to quickly access
power settings and view the remaining battery charge.
●
To reveal the percentage of remaining battery charge and the current power plan, on the
Windows desktop, point over the power meter icon.
●
To use Power Options, click the power meter icon and select an item from the list. From the
Start screen, you can also type power, select Settings, and then select Power Options.
Different power meter icons indicate whether the computer is running on battery or external power.
The icon also reveals a message if the battery has reached a low or critical battery level.
Running on battery power
When a charged battery is in the tablet and the tablet is not plugged into external power, the tablet
runs on battery power. If the tablet has a charged battery installed and the AC adapter is
disconnected from the tablet, the tablet automatically switches to battery power and the display
brightness decreases to conserve battery life. The battery in the tablet slowly discharges when the
tablet is off and unplugged from external power. When the tablet is attached to the keyboard base,
the system is powered by the keyboard base's battery until the battery reaches a critical level in the
keyboard base. At that time, the system switches to the tablet's battery.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the tablet, and other factors.
NOTE:
There is a secondary battery in the keyboard base. When the tablet is attached to the
keyboard base, the system is powered by the keyboard base's battery.
