Power problems on the Aviation Tablet come in two flavours: the tablet will not charge, or it does not switch on and off with the avionics master when it is in the docking station. The second one is a setting.
The tablet will not charge
- Use the charging cable and adapter that came with the tablet. Many third-party USB-C cables do not deliver enough current.
- Hold the power button down for a long press (20 seconds or more) to force a hard reset, then try charging again.
- If it still shows no charge, let the battery run completely flat: open iFly EFB and leave it running until the tablet shuts down. Then connect the charger and leave it for a few hours.
If none of that works, the charging circuit needs to be looked at on the bench. Email support@iFlyEFB.com with the tablet's serial number and what you tried.
Docked tablet does not follow the avionics switch
When the docking station is wired to ship's power through its round plug, the tablet can power on and off with the avionics master. That behaviour is controlled by the ACC setting on the tablet:
- Open the tablet's Settings app and scroll down to ACC Setting.
- Make sure it is enabled.
- Select the Shutdown option, then set a delay of 3 to 5 seconds. The delay stops the tablet from shutting down on a momentary voltage dip.
