Power Management Requirements
Most of the power management is behind the scene and should be invisible to the student.
The Power Management Table details what sections of the laptop are powered in different states. A more detailed description of the implementation is available at Hardware Power Domains.
Screen off
*PW1 After X minutes of inactivity through keyboard, mouse, directional, or gamepad keys, the screen will turn completely off (black), unless a running activity has asked to inhibit this timeout.
- PW2 In this mode, the mesh network is working properly and can forward packets.
- PW3 The screen will turn back on at the press of any key on the keyboard, mouse, directional or gamepad keys. The back light will come back on to the level it was before the screen was turned off. The key press will not be acted upon.
Suspend/Resume Button
The purpose of the 'suspend/resume' button on the laptop is to allow a child to leave the laptop open with the antenna up (and potentially having set up a good RF relay); and go into suspend with only the wireless on. The 'suspend' that happens is the same as that when the lid is closed, but that changes the RF characteristics quite a bit.
- PW4 Pushing the 'Suspend/Resume' button (previously the power button), will put the laptop into suspend mode, which includes Screen off.
- PW4.1 In suspend mode, the laptop will continue to forward mesh networking packets if it is in the path between other mesh points (laptops, school servers).
- PW4.2 Pushing the 'Suspend/Resume' button when the laptop is suspended will return it to powered on state with the same activities running as before it suspended.
- PW4.3 Pressing any key on the keyboard, the mouse, directional keys or gamepad keys will also return the laptop to its full operational state. The button will not be acted upon.
- PW5 When the battery gets to its defined shut down level, whether in suspend mode or full operational mode, it will shut down gracefully, without data destruction.
- PW6 The student must be able to execute a full power down of the laptop from the Sugar home view.
Lid Closed
Whenever a student closes the lid, the laptop should go into suspend mode to save battery power. Wireless is still operational.
- PW7 When the lid is closed on the laptop, it will have the same affect as pushing the suspend/resume button (see Suspend/Resume Button).
- PW8 When the lid is opened, the laptop will resume (or, it may be necessary for the student to press a key or the suspend/resume button)
Ebook mode
Behind the scenes, reading should consume the least amount of power after 'suspend'. The student shouldn't notice anything when in ebook mode.
- PW9 A student can download a pdf file, and click on it. It will format and open for reading on the screen in low power mode. The screen brightness button can be used to reduce the power consumption even more.
- PW10 The student can convert the laptop to tablet mode and use the directional keys for scrolling through the text.
- PW11 If the student presses the rotate button, the screen will rotate 90 degrees. (This is in any mode, not just ebook mode !)
- PW12 In ebook mode, the screen may be turned off (see Screen Off) if there is no input activity for a fixed time period.
