FAQ -

  • Q IC card can not be opened
    A
    1. Check if the IC card holder is deformed or broken, and if there is any solder joint
    2. Check if the modules UART1_TX and UART1_RX are well connected to Q9 and Q10.
    3. Check if the 5V power supply of the AU9560-GCS control IC is normal.
    (1) Check the U28 boost IC circuit if there is no 5V output
    (2) If there is a 5V output, it may be an AU9560-GCS control IC problem. Check whether the internal LDO output
    of the AU9560-GCS control IC is 1.8V and 3.3V. Check the related circuit of the AU9560-GCS control IC
    connection.
    4. The above check has no abnormality and replace the AU9560-GCS control IC to confirm
  • Q Battery is not charging
    A
    1. Confirm the battery is bad, check whether the appearance of the battery is deformed or damaged,
    and whether the battery holder and the battery are in poor contact.
    2. Check if the DC head or Micro USB port of the charging connector is deformed or broken, and if
    there is any solder joint
    3. Use a multimeter to measure whether the battery voltage is above 4.2V. If it does not reach 4.2V, put
    the battery into the normal machine, charge it with OK power for 1 to 2 hours, and then measure whether
    the battery voltage has increased.
    (1) If the battery cannot be charged properly, the battery may be a problem.
    (2) If the battery is charging normally, the motherboard may be faulty.
    4. Put the OK battery into the problem machine, use the OK power supply to charge the machine, and
    observe the 5V power input current.
    (1) If the charging current device does not display charging, re-burn the firmware and confirm
    (2) If there is no charging current, check whether the DC head or Micro USB port is deformed or
    broken, whether there is solder joint welding, and whether the battery holder and the battery holder are in

    good contact. Check if the DC IN pin of the module is broken or soldered or shorted, and the pin bypass
    capacitor is shorted.
    5. The above checks are invalid.
    (1) If the DC head is not charged, check if there are any solder joints or short circuits at the legs of
    modules 141 and 142. Check if D14 is short-circuited or damaged.
    (2) If the Micro USB port is not charged, check if U26, B5, and D1 are abnormal, and replace U26
    without any abnormality.
