Ok, so I'm in some old habits at the moment. I'm sat at the kitchen table on my MBA, typing away. I've noticed when I get up, I'm careful not to disturb the table which doesn't make sense given MacBook is somewhat lacking in moving parts, namely the platter! Now, I'm going to put the MacBook away for about 90 minutes but this time, instead of shutting it down........ I'm just going to close the lid......

I'm currently at 52% batter. What effect would you expect the 90 minutes sleep to have on the battery?

Signing off......

You can close the lid to sleep your MBA anytime. You can also move your MBA anytime. As long as you're not dropping it or bumping it hard enough to dent it, you can't hurt it. Turn it upside down, sideways, etc., use it in the car or on a train or plane. It won't have any effect.

As far as battery, expect to use about 1% battery for every hour of sleep. If it goes into standby mode (MacBook Air (Late 2010) and later: About standby mode) (hibernation) (typically after an hour of sleep), it should last around 30 days on a full battery charge. This should answer most, if not all, of your battery questions:

Also, you may have better success in attracting responses to your thread, and you'll make your thread easier to find for those searching for the same answers, if you follow this tip (http://forums.macrumors.com/showpost.php?p=11815146&postcount=2).

I'm not even sure I really followed the OP's post either. It tends to wander in multiple directions (like what does the MBA not having moving parts have to do with how much battery power will be lost putting your laptop in sleep mode?) and uses random punctuation.

Having opened the lid, I see one percentage point gone. The start up was pretty much instant.

I've been doing that for years with laptops. What exactly was the experiment?

I haven't turned off my mac in years, except when boarding planes. Instant sleep/wake is one of the awesome features of the MBP/MBAs.

LOL, dude...I think you need to put yourself in sleep mode for a little bit. What are you trying to test? Moving around a laptop or battery life in sleep mode?

Guys - chill, the dude's just shell-shocked from how super cool awesome his new MacBook is. More power to ya: super stupefied MacBook Air man!

Also, I have begun to notice how GGJstudios consistently provides the most well-linked replies in an almost painful-to-watch patient manner. Dude's a robot!

I actually have a longer game in mind. I've been looking on various Mac related forums for common issues. My next test (probably overnight tomorrow) is to leave the MacBook Air in standby overnight, check it in the morning and confirm (or not) that it goes into hibernation.

Mine wakes up as instantaneously whether after 15 min or 8 hours, and after 8 hours, I see battery at about 96-97%. So, is it actually going into deep sleep? Instant awake but not much battery drain.

Thank you. Your experience seems to differ a little from some accounts I've read here and elsewhere. I'll report back as to what mine is.

67% remaining at 8PM last night when I closed the lid and 65% today so i) Apple's claims of 30 days sound reasonable and ii) I don't have a possibly common fault I've seen reported here and elsewhere.

After opening the lid today, it took about two seconds for the mouse pointer to appear, after which the login/password appeared (about 3-4 seconds in total from opening the lid). This seems consistent with what I've read from other posters here.

Man my laptop wakes up instantaneously about 10% of the time. Otherwise I wait between 4-12 seconds for it to wake. And sometimes I literally close the lid, forget I needed to send an email and reopen and have to wait 10 seconds...:mad:
