Abstract
Techniques described are capable of receiving an indication that an operating system of a computing device has entered a hibernated state and, in response, booting the computing device from a trusted environment that is unalterable by the hibernated operating system. A component stored on or accessible by the trusted environment may then perform an operation on the computing device. This operation may include scanning the device, performing a memory test on the device, or updating firmware on the device. In some instances, the computing device enters the hibernated state due to a predetermined length of user inactivity on the computing device. As such, the described techniques may perform an operation on the computing device without user interaction causing the operation.
