How much battery would leaving my laptop at "sleep" mode consume? is the consumption low enough so that it would be safe to leave the laptop sleeping at nights regularily and using it tommorow?
What's the recommended period of time for which I should not turn it off, but let it sleep. (for example, if I'll use the computer in a minute - turning it off instead of making it to sleep will definitely not save battery due to the overhead of turning your computer on and off).
