Abstract: Systems and methods are provided for grouping remote desktop sessions on servers in remote desktop environments according to predicted user logoff times so that sessions with similar predicted logoff times can be placed together on the servers, allowing for more efficient utilization of servers. A user can request a virtual desktop session. Once the request is received, a predicted logoff time for the session can be determined and the session can be placed on one of available host servers based on the predicted logoff time. Different logoff time ranges can be assigned to different servers and sessions can be grouped on the servers according to predicted logoff time.

Abstract: In an example, a computing device may include a battery, a controller to monitor an operation of the battery, and a basic input/output system (BIOS). The BIOS may initiate a boot process to load an operating system of the computing device.
