Charging the battery
With repeated discharges and recharges, the battery’s
capacity gradually decreases. A frequently used older
battery does not power the device for as long as a new
battery, even when fully charged.
TECHNICAL NOTE: The device drains the battery faster
at low temperatures. Check your remaining charge
frequently if you are working in temperatures below 50
degrees Fahrenheit.
The device calculates the remaining battery charge
based on your current rate of power use and other
factors such as the age of the battery.
What to do when the battery runs low
When the battery run low you can:
❖ Plug the device into an external power source and
recharge the battery via the Micro USB port, using the
USB Power cable and USB/AC adaptor. See
“Connecting to a power source” on page 36
❖ Save your work and turn off the device
If you do not manage to do either of these things before the
battery completely runs out of power, the device
automatically enters a power-saving state and turns itself off
so that when you turn on the power again after connecting
the USB/AC adaptor, you can continue where you left off.
Setting battery notifications
You can set two notifications. Each notification can be set to
alert you when a specified percentage of remaining battery
power has been reached. You can also set the device to
enter Sleep mode or to completely shut down when the
notification goes off.
To change the default notification settings:
1 While on the desktop, touch the
Battery ( ) icon in the
notification area.
