Sony VAIO Tap 21 Multitouch Mobile Desktop Review
Before bringing this article to a close, we'd like to cover a few final data points--namely, power consumption and noise. Throughout all of our benchmarking and testing, we monitored acoustics and tracked how much power our test system was consuming using a power meter. Our goal was to give you an idea of how much power each configuration used while idling and also while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not of an individual component.

The Sony VAIO Tap 2 sips power. The full system--including the screen no less--consumed only 51 watts under load. At idle, the system consumed only 21 watts. And if you let the machine idle to the point where the screen shuts down, that number drops all the way down to only 7 watts.
With power consumption so low, it should come as no surprise that the Sony VAIO Tap 21 is virtually silent. There is a fan in the system that can be heard in a quiet room when it spins up, but this machine is as quiet as an actively-cooled rig can get.
