asiri -- thank you for the clear explanation. power management is a tradeoff between saving power, and keeping the laptop useful for the user (otherwise we would simply turn it off altogether to save power ;-).
we try to acheive this goal is to save power by putting the laptop into suspend when the user isn't obviously using the laptop -- i.e., when the laptop is idle. (this is not something that can be determined exactly, of course.) in the case of audio and video, we assume that the user would like to hear, or see, the music or movie they have selected, so when we detect these activities, we try and inhibit idle suspend. so if there is buggy behavior, it's if the laptop _does_ suspend while playing audio or video. paul asiri wrote: > Hi James > > Thanks for both of you James & Paul , for your reply's. > > I will explain my understanding on the OLPC power management functionality. > Please correct me if I am wrong. > > 1.
