Hi,
I'm sorry to inform you that we do not support the Microsoft Surface Pixelsense Coffee Table Unit. However, I can provide you with general instructions for powering up a Microsoft Surface device. For Surface devices, you need to plug in the power cable into the back of the device and a power outlet, then press the power button on the device. If the device has external ports, they will be available once the device boots up. It's also recommended to follow any device-specific setup prompts and configurations. I hope this information helps.
