Abstract
Technologies for hybrid sleep power management include a computing device with a processor supporting a low-power idle state. In a pre-boot firmware environment, the computing device reserves a memory block for firmware use and copies platform wake code to a secure memory location, such as system management RAM (SMRAM). At runtime, an operating system may execute with the processor in protected mode. In response to a request to enter a sleep or suspend state, the computing device generates a system management interrupt (SMI). In an SMI handler, the computing device copies the wake code from SMRAM to the reserved memory block. The computing device resumes from the SMI handler to the wake code with the processor in real mode. The wake code enters the low-power idle state and then jumps to a wake vector of the operating system after receiving a wake event. Other embodiments are described and claimed.
