If Something Goes Wrong
Power and the batteries
Power and the batteries
Your device receives its power through the USB/AC adaptor
and USB/power cable 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 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.
The device does not power on.
Let the battery discharge completely, then try charging it
again.
Check the power options. For more information, see
“Optimizing battery life” on page 28
. 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.
If the device still does not power on, contact your service
provider immediately.
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.
