Problem
Possible causes
Possible solution
Poor contact between the device and
charger.
Check all connectors to ensure that all
connections have been properly made.
Shortened standby
time
The standby time is related to your
service provider system configuration.
The same device used with different
service providers’ systems will not
provide exactly the same length of
standby time.
If you are located in an area where
signaling is weak, temporarily power
off the device.
The battery is depleted. In high
temperature environments, battery life
will be shortened.
Use a new battery.
If you are not able to connect to the
network, the device will continue to send
out signals as it attempts to locate a
base station. Doing so consumes
battery power and will consequently
shorten standby time.
Change your location to one where the
network is accessible, or temporarily
turn off your device.
Cannot turn your
device on
Battery power has been depleted.
Recharge the tablet’s battery.
