By March 2026, general-purpose classrooms listed here will offer power and charging via USB-C. When you connect your laptop with this cable (pictured below and marked blue in classrooms), it will send video and audio to the display while receiving up to 60W of power.
What’s New
- One cable connection: USB-C carries video, audio, and power.
- Automatic charging: Up to 60W power delivery while connected.
- No workflow change: Use the USB-C source selection on the touch panel (marked blue).
Prerequisites
- Your laptop must have a USB-C port that supports DisplayPort Alt Mode and Power Delivery (PD). Many modern laptops, including Apple MacBooks, iPhones, iPads with USB-C, Dell XPS and Latitude series, Microsoft Surface series, and others, support USB-C charging. Some lower-end laptops and certain Android devices may not support charging.
- Not all USB-C ports are the same. While many laptops use USB-C for charging, some may only support data transfer and video output, not power delivery. This device provides up to 60 watts of charging power. If your laptop needs more than 60W for fast charging, it may charge slowly or maintain its battery level. Bring your AC adapter as a backup.
- If your device lacks USB-C, continue using the HDMI cable (charging will not occur over HDMI).
Confirm Charging (optional)
- Windows: The battery icon should show a charging symbol; hover to see “Charging.” Note: Your battery icon may look different.

- macOS: The battery menu should read Power Source: Power Adapter or similar. Note: Your battery icon may look different.

Troubleshooting
- Laptop isn’t charging
- Ensure you are connected with the USB-C cable (marked blue). Charging does not occur over HDMI.
- Some laptops need more than 60W for fast charging; the battery may charge slowly or stay the same.
- Unplug and replug the USB-C cable; wait 5–10 seconds for devices to recognize.
- If available, try another USB-C port on your device and ensure the lid is open/awake.
- If your battery continues to drain, connect your original AC power adapter.
- Mac shows image but isn't charging
- Check the battery menu; if it says “Using Battery,” try a different USB-C port or cable orientation.
- Verify the port supports Power Delivery (some older laptops and Macs/Chromebooks have mixed-capability ports).
Tips
- For a reliable connection, plug the USB-C cable in firmly and avoid using dongles between the room cable and your laptop.
- Bring your charger for all-day sessions if your laptop consumes a lot of power or has an old battery.
