Abstract
Procedures for resumption from a low activity condition are discussed. In implementations, a persistent state file, or a portion thereof, is secured via an encryption algorithm, with the decryption key secured via the operating system (OS) login user credentials. Once a user is authenticated via the OS login, the persistent state file may be decrypted and inserted in the OS boot path with resumption occurring through the persistent state file.
