I suspect the answer could as simple as a simple timer - upon no activities for some time T1, save the screen and power down into low power mode. I am aware that Motorola Rokr E2 handphone, which will go into screensaver mode after some period of inactivites on its keys, Motorola gladly release their source code (which is linux kernel based). https://opensource.motorola.com/sf/projects/rokre2 or may be it could be the screensaver application (java based?) doing this? I really don't know :-). On Mon, Oct 6, 2008 at 12:07 PM, <ashok.shanmugam@xxxxxxxxx> wrote: > Hi all > > I have completed implementing power management callbacks of s2ram for a ppc > board.
