Behaviour – Equipment faults
If you find that you are unable to start up your device, please check whether the EFUSE has been tripped. If it has, the LED will be lit up red. When the EFUSE has been tripped, you will need to wait for at least one minute before reactivating the EFUSE. To check again, switch your device off and briefly press the reset button to reactivate the EFUSE. The LED on the EFUSE must now light up green.
Now switch your device on. If the EFUSE is tripped (red LED), your device is causing an unusually high current flow, which indicates there is a fault in your device. You should have further tests carried out in this case and have the device checked by a specialist dealer. The fast and safe power interruption provided by EFUSE should have helped prevent any further damage being caused to your device.
