Troubleshoot Surface Hub power issues

If you encounter an issue powering on your Surface Hub 2S or Surface Hub 3, review the troubleshooting steps outlined on this page.

  1. First, remove all connections to the Surface Hub except for Ethernet and power.
  2. Ensure Surface Hub has a direct connection to a dedicated power outlet.
  3. Do you have an APC Charge Mobile Battery connected to Surface Hub? If yes, disconnect the battery and try again. If the power-on issue only occurs when using the APC battery, please contact APC support for further assistance.
  4. Test with another power cord (see Label 2 in Figure 1 below) and a different power outlet.
  5. Initiate a hardware reset on Surface Hub: Hold and press the power button (see Label 11 in Figure 1 below) for at least 20 seconds.
  6. If you’re still unable to power on the device, try reseating the compute cartridge.
