Conserving battery power
How long a fully charged battery lasts when you are using
the device depends on a number of factors, such as:
❖ How the device is configured
❖ How much you use the internal storage drive or other
optional devices
❖ Where you are working, since operating time decreases
at low temperatures
There are various ways in which you can conserve power
and extend the operating time of your battery:
❖ Enable Sleep, which saves power when you turn off the
device and turn it back on again
❖ Use the Windows
®
power-saving option plans
These power-saving options control the way in which the
device is configured. By using them, you can increase the
length of time you can use the device before you need to
recharge the battery.
Microsoft

Plans. Using one of these power plans lets you choose
between maximum power savings and peak system
performance. You may also set individual power-saving
options to suit your own needs.
