Common troubleshooting
Q.: When the device will not start up what are the basic detection steps?
Answer:
1. If the device can start up via adaptor powering, it means the battery power is low.
2. Ensure the indicator of the power adaptor lights and the adaptor works normally.
Q. : What to do if water accidentally runs into the device?
Answer:
1. It is strictly forbidden to boot the device which may result in more serious damage to the tablet
computer.
2. Wipe dry the device surface, and then take it to a professional service center for repairing
immediately.
Q.: How to restore the default settings?
Answer: Open the " Settings " > " backup and reset " > " restore the default settings " > reset the
computer. Save your data before restoring default settings.
Q.: How to prolong the use time of the battery?
Answer:
1. Adjust LCD screen brightness to a proper value.
2. Adjust to appropriate volume.
3. Adjust to proper screen timeout time.
Q.: Although having a normal network connection, Internet is still slow, what to do?
Answer: It is recommended to clear your browser cache, for specific operations please refer to the "
browser " part.
Q.: The device hangs, what to do?
Answer: Hold the power button to shut down the device.
Common corrective maintenance
Bug 1) Starting up fails, screen doesn’t show the self-testing picture.
1. Press the power button and check whether the indicator light lights up red. If not, then check if the
power adaptor is connected. Start up after charging it for 10 minites (caused by low battery).
2. Check whether power socket of mainboard is plugged alright.
3. Check whether the adapter is 5V2A, otherwise check if there is short circuit or leakage.
4. Check whether the mainboard has a scorching smell caused by integrated heating or line short
circuit.
Bug 2) When pressing the power button the power indicator and voltage are all normal, there may
be two situations:
1. Firmware or software bug: programme the firmware again.
2. Hardware bug: first check by hand whether the mainboard is heated, the connecting line is well

connected, try to find out which part is malfunctioning by replacing by turns the mainboard and the
LCD and launching the device.
Bug 3) Starting up crash at the stage of starting up picture.
Malfunction can indicate problems of two aspects:
1. Firmware of software: caused by a loss of the document package or too much software installed,
the suggestion is to reinstall the firmware.
2. Hardware malfunction: a) check whether the voltage is too low, the adaptor is well connected,
usually caused by low battery or a failure of the battery. b) Motherboard’s damaged, replace the
motherboard.
Bug 4) The battery can’t be charged after starting up . Possible reason:
1. Check whether the battery lines are in good condition and the battery doesn’t have a leakage.
2. Check whether the power supply VCC+3.5v~4.2V of battery is functioning.
Bug 5) USB, HDM, SD cards don’t function.
1. The three connections lead to motherboard directly, so first check if there are any bad contacts or
broken connection.
2. Check if the external device is compatible with the original device.
3. Due to the frequent inserting and pullting out, the solder between the connector and the
motherboard might not be in good condition, re-solder it or renew the connector.
Bug 6) The camera doesn’t work.
1. Check if the camera is activated or there is dust in the lens.
2. Check the hardware, check whether sensor is connected well to the motherboard, replace the
sensor to see if it’s broken, otherwise it is the motherboard bug.
Bug 7) WIFI does not work.
1. Check whether WIFI can be started, please refer to the instruction to get details.
2. Check the hardware, whether the WIFI board and antenna are well connected, check voltage of
WIFI board, crystal oscillator.
