Description
Mechanical Off - All devices in the system are turned off completely. No electrical current is running
through the system. Except for the real-time clock, power consumption is zero. The machine can
be worked on without damaging the hardware or endangering service personnel.
Soft Off - The computer consumes a minimal amount of power. No user mode or system mode
code is run. It is not safe to disassemble the machine in this state.
The computer consumes a small amount of power, user mode threads are not being executed,
and the system "appears" to be off (from the end user's perspective, the display is off, and so on).
It is not safe to disassemble the machine in this state.
Working - The system dispatches user mode (application) threads and they execute. In this state,
peripheral devices are having their power state changed dynamically. The user can select, through
some UI, various performance/power characteristics of the system to have the software optimize
for performance or battery life. The system responds to external events in real time. It is not safe
to disassemble the machine in this state.
Mechanical Off - All devices in the system are turned off completely. No electrical current is running
through the system. Except for the real-time clock, power consumption is zero. The machine can
be worked on without damaging the hardware or endangering service personnel.
