Be sure to look for the ENERGY STAR when shopping for slates and tablets
Current Specification Effective Date: November 18, 2018
The ENERGY STAR certified computer product criteria require that computers operate efficiently in multiple modes of operation (such as Off, Sleep, and Idle), utilize efficient power management features, and utilize energy efficient power supplies.
The ENERGY STAR performance specification covers desktops, integrated desktops, notebooks, slate/tablets, portable all-in-ones, thin clients, and workstations, tailoring the criteria to each product type. It provides a base allowance per product type, which limits the amount of energy the product can consume and then adds allowances for features that increase energy demand. In addition, the specification sets requirements for power management. These are set so that the display will go to sleep within 15 minutes of user inactivity and the system will go to sleep within 30 minutes of user activity.
