Airs do go into standby mode more readily than other macs.
Assuming its not just the extra time to exit standby mode (and isn't really sleeping anymore), have you checked the startup disk preference as the article above recommends?
You may have to look in the console log for sleep / standby messages in case your mac is entering standby / hibernate earlier than the expected one hour. The pmset
command can show you the details of your Air's power management settings. Here's what a Mid 2011 Air looks like with mostly default settings:
mac:~ me$ pmset -g
Active Profiles:
Battery Power -1
AC Power -1*
Currently in use:
standbydelay 4200
standby 1
womp 1
halfdim 1
panicrestart 157680000
hibernatefile /var/vm/sleepimage
networkoversleep 0
disksleep 10
sleep 10
hibernatemode 3

displaysleep 10
acwake 0
lidwake 1
You can also use pmset
to change either the number of seconds before standby kicks in, which is standbydelay
; or turn standby off completely by setting standby
to 0
. Use the command man pmset
for details.
