To keep your device always up to date, it is extremly important to regularly connect the device to the internet.

You can change this setting. To do this, enter the settings and choose "Update and Security" -> "Windows Update" -> "Advanced Options" and select the desired installation method for updates.


Why does the PRIMEBOOK C13 battery never show a fully charged battery?  

Within a smaller number of our devices, a faulty software is responsible that only a battery level of 85 to 90 percent can be displayed on the affected devices after an extended charging cycle.

However, this is only a display error and not a hardware effect. We can fully confirm after an extensive testing that the batteries of the affected devices can be 100 percent charged - even if the display may indicate a different number.

We are currently working on a software solution to fix the display error for your PRIMEBOOK C13 in the near future.

Why is my PRIMEBOOK C13 charging slowly?  

If you have connected the PRIMEBOOK C13 for charging and set your device at high exposure at the same time (eg movie playback at 100 % display brightness while surfing, chatting or playing), the battery is charging very slow due to the stress. We recommend you therefore to load the device in the off state.

Why is no sound coming from my PRIMEBOOK C13?  

You may have headphones connected to your PRIMEBOOK C13. If headphones are connected the loudspeaker of the device is automatically turned off. Disconnect the headphones from the device to re-enable the speakers. If there is still no sound, check if the sound of the device is turned on and if the volume is set high enough.

Why can't I turn on my PRIMEBOOK C13?  

Perhaps the charge of the battery isn't enough to turn the PRIMEBOOK C13 on. Connect the charger to the device to recharge the batttery.
