If Something Goes Wrong
Power and the battery
Power and the battery
The device’s battery may not be accessible by the user.
Your device receives its power through the Micro USB/AC
adaptor or from the system battery. Power problems are
interrelated. For example, a faulty Micro USB/AC adaptor will
neither power the device nor recharge the battery.
Here are some typical problems and how to solve them:
The USB Power cable to the Micro USB/AC
adaptor work correctly, but the battery will not
charge.
The tablet’s 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 has completely discharged, it will not begin
charging immediately. Leave the Micro USB/AC adaptor
connected, wait 20 minutes and see if the battery is
charging.
The battery appears not to power the device for as
long as it usually does.
If you frequently repeat shallow charge and discharge, the
battery meter may become inaccurate. Let the battery
discharge completely, then try charging it again.
Check the power options via your Power Plans (see
). Have you added a device that takes its
power from the battery? 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.
