Power and the batteries
Your device receives its power through the included USB
power cable (connected to a power source) or from the
system battery. Power problems are interrelated. For
example, a faulty USB/AC adaptor or USB/power cable will
neither power the device nor recharge the batteries.
Here are some typical problems and how to solve them:
The optional compatible USB/AC adaptor and
USB/power cable work correctly, but the battery
will not charge.
The battery does not charge while the device is consuming
full power. Try turning off the device.
The battery may be too hot or too cold to charge properly. If
you think this is the probable cause, let the battery reach
room temperature and try again.
Let the battery discharge completely, then try charging it
again.
Check the power options. For more information, see
“Optimizing battery life” on page 29
. Is your software using
the internal storage drive more? Is the display power set to
turn off automatically? Was the battery fully charged to begin
with? All these conditions affect how long the charge lasts.
After a period of time, the battery will lose its ability to
perform at maximum capacity and will need to be replaced.
This is normal for all batteries.
