    I have 3 AlldoCube X tablets now for 4 months.

    One of them now won’t boot aftrer a normal power-hold turnoff device.

    Power button won’t start and there is no led and black screen.

    I’ve tried to hold power  button for 1 minute to force shutdown and after charging for 2 hours to boot.

    Also Boot+volume up .      Boot+Volume down

    No cables or usb attached booting.

    I’ve used the other adapters and cables from the other tablets as well.

     

    Nothing no life Signs, no led, no screen.

     

    How to proceed?

    You can try connecting to your computer via USB to see if a new device will pop up in the Windows System Device Manager.
    In addition, if you have a device that can monitor the output current of the charger, check the output current and voltage of the charger.

    I have a usb multifuntion tester, it shows about 5V and 0.05-0.58A as the battery is fully charged.

    Connecting to a laptop with Windows 10 shows the same VA info, but Windows doesn’t see the USB device. (also without the tester).

    Also not on different ports, different cables, different pc. Power button still no success.

    Even forcing Windows to search for devices in the controll panel gives no result.

     

    regards,

    Harald.

    Is this a product failure, a case of garantee?

    How to proceed?

    “Connecting to a laptop with Windows 10 shows the same VA info”——what’s this va info means?
