Device Not Powering On

CoreBAR doesn't respond when connected to power.

🔌

CoreBAR Won't Turn On

Solved

Your CoreBAR shows no signs of life when connected to the power adapter. No screen, no lights, no response.

Solution

Check the power adapter: Make sure it's securely connected to both CoreBAR and the wall outlet
Try a different outlet: The outlet may not be providing power
Check the adapter assembly: Ensure the plug head is properly locked (rotate toward "LOCK" until you hear a click)
Wait 20 seconds: CoreBAR's boot animation takes about 20 seconds to appear
Try a different USB-C power source: A 5V/2A USB adapter or a high-power USB port on your PC

Tip: If you're using a multi-module setup, you may need the DC 12V power supply for stable power delivery.

Screen Stays Black

CoreBAR powers on but the screen remains black.

🖥️

Screen Stays Black After Boot

Solved

CoreBAR appears to be powered on (you can feel heat or see indicator lights), but the screen remains black or unresponsive.

Solution

Wait longer: First boot can take up to 60 seconds
Check brightness: Try swiping down from the top of the screen and adjusting brightness
Restart CoreBAR: Unplug power, wait 10 seconds, and plug back in
Check for firmware corruption: If still black after restart, contact support

Note: If the screen is black but you can feel haptic feedback on touch, the screen may be in a low-power state. Swipe up from the bottom edge to wake it.

Modules Not Powering

Modules attached to CoreBAR aren't receiving power.

🧩

Modules Not Receiving Power

Solved

Modules attached via QuantumLink™ are not powering on or responding. No lights, no display, no haptic feedback.

Solution

Check the magnetic connection: Modules should snap firmly into place
Reattach the module: Detach and reattach it to ensure a clean connection
Check for debris: Clean the pogo pins on both CoreBAR and the module
Check power budget: If you have more than 3 modules attached, use the DC 12V power adapter
Restart CoreBAR: Unplug power, wait 10 seconds, and plug back in

Tip: The maximum power draw increases with each module. For heavy setups, the DC 12V adapter provides stable power delivery.

Power Adapter Issues

Problems with the power adapter itself.

🔋

Power Adapter Not Working

Solved

The power adapter doesn't seem to be supplying power to CoreBAR.

Solution

Check the adapter assembly: Make sure the plug head is fully locked (rotate toward "LOCK" until click)
Inspect the cable: Look for any visible damage to the adapter or cable
Try a different adapter: Use a 5V/2A USB power adapter or a high-power USB port
Check the port: Inspect CoreBAR's DC 12V port for debris or damage
Use the PC-LINK port: You can power CoreBAR via the USB-C PC-LINK port as an alternative

Note: If you're using a USB-C power source, ensure it supports 5V/2A or higher. Not all USB ports provide enough power.
