Troubleshooting
Possible causes
You have entered an incorrect
PIN code three consecutive
times.
The battery or battery charger is
damaged.
The ambient temperature is
below 0°C or higher than 40°C.
Poor contact between the
battery and charger.
The battery has no charge.
The duration of standby time
is affected by your service
provider's system configuration.
The same tablet used with
different service providers'
systems does not have the
same duration of standby time
(LTE/HSPA+ only).
If you are not able to connect
to the network, the tablet
continues to send out signals
as it attempts to locate a
base station. Doing this
consumes battery charge and
consequently shortens standby
time.
Your tablet is in airplane mode
with no wireless connectivity.
The network signal strength is
not strong enough.
Possible solutions
Contact your service
provider to get the PUK
code.
Contact the sales
corporation.
Adjust the battery
charging environment
to avoid extreme
temperatures.
Check all connectors
to ensure that all
connections have been
properly made.
Charge the tablet.
If you are located in an
area where the network
signal is weak, move
your location to the area
where the network signal
is strong or temporarily
turn off your tablet if
needed.
Change your location to
one where the network is
accessible, or temporary
turn off your tablet or set
it to airplane mode.
Slide the status panel
down and then disable
AIRPLANE MODE.
Try moving to a different
location for better signal
reception.
