MBA 11" won't go into standby mode

hello!

i've discovered macbook airs have amazing feature saves lots of battery when in sleep mode.

i've noticed mine doesn't perform should.

charged battery 100% , closed lid. next morning battery had dropped 88%.

standby feature tells that, when in sleep mode, after 1 hour, macbook air go standby mode , battery last 30 days.

i've run command "pmset -g" , here's following:

active profiles:
battery power -1*
ac power -1
in use:
standbydelay 0
standby 0
halfdim 1
panicrestart 157680000
hibernatefile /var/vm/sleepimage
disksleep 5
sleep 10
hibernatemode 3
ttyskeepawake 1
displaysleep 5
acwake 0
lidwake 1

see "standby" 0. shouldn't number?

please, tip great!

thanks!

 

what re looking called hibernate mode think

apple hibernation has 3 modes. default, on laptops suspends system , make copy of ram disk safe hibernate.
can change mac’s hibernate behavior using pmset; here’s reference it:
http://developer.apple.com/documentation/darwin/reference/manpages/man1/pmset.1.html
“sudo pmset -a hibernatemode 0″ = suspend ram (default on desktops)
“sudo pmset -a hibernatemode 1″ = suspend disk only
“sudo pmset -a hibernatemode 3″ = suspend disk + ram (default on laptops)
see current hibernatemode: “pmset -g | grep hibernate mode”.


machine hibernate mode 3 should be.
