100 If Something Goes Wrong

Power and the batteries

Power and the batteries
Your device receives its power through the USB/AC adaptor and
power/docking connector cord or from the system battery. Power
problems are interrelated. For example, a faulty USB/AC adaptor or
power/docking connector cord will neither power the device nor
recharge the batteries.
Here are some typical problems and how to solve them:

The USB/AC adaptor and power/docking connector cord

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.
If the battery light does not glow after a few minutes, the battery
may have reached the end of its useful life.

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 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.
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.
For more information on maintaining battery power, see “Charging
the battery” on page27.
Display problems

The screen does not look correct.
