Hello!

I've just discovered that macbook airs have this amazing feature that saves lots of battery when in sleep mode.

However I've noticed that mine doesn't perform as it should.

I charged the battery to 100% and closed the lid. Next morning the battery had dropped to 88%.

The standby feature tells that, when in sleep mode, after one hour, macbook air will go into standby mode and then its battery will last 30 days.

I've run the command "pmset -g" and here's the following:

Active Profiles:
Battery Power -1*
AC Power -1
Currently 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

I see that the "standby" is 0. Shouldn't it be another number?

Please, any tip is great!

Thanks!

what you re looking for is called hibernate mode I think

Apple hibernation has three modes. By default, on laptops it suspends the system and make a copy of RAM to disk for a completely safe hibernate.
You can change the Mac’s hibernate behavior using pmset; here’s the reference for it:
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/pmset.1.html
“sudo pmset -a hibernatemode 0″ = suspend to RAM only (default on desktops)
“sudo pmset -a hibernatemode 1″ = suspend to disk only
“sudo pmset -a hibernatemode 3″ = suspend to disk + RAM (default on laptops)
To see your current hibernatemode: “pmset -g | grep hibernate mode”.


your machine is hibernate mode 3 which is as it should be.

I think it should be a "1". Would definitely call Apple or speak with a genius though unless you want to try fixing it yourself. I'd back your computer up too, you never know.

Hmmm so how come the battery still decreases like a regular macbook pro in sleep mode?

I don't see how it would last 30 days with this battery drop rate.

What am I doing wrong or what is it missing?

have you changed the hibernation mode?

Yes, using those hibernate commands all that's changed is the hibernation, but the standby is still 0.

I really think it shouldn't be 0, if you think logically, 0 mean not enabled.

But the mba is brand new, I've never messed up with it. And I really think this standby thing should be the default option.

i just spent a few minutes searching online for combinations of pmset-g, power, sleep, and standby/delay and I can find nothing that even mentions standby. I can find mention of sleep delay, which is time until sleep in minutes, I believe.

from man page. http://www.manpagez.com/man/1/pmset/


hibernatemode takes a bitfield argument defining SafeSleep behavior. Passing 0 disables SafeSleep altogether, forcing the computer into a regular sleep.

standby causes kernel power management to automatically hibernate a machine after it has slept for a specified time period. This saves power while asleep. This setting defaults to ON for supported hardware. The setting standby will be visible in pmset -g if the feature is supported on this machine.

standbydelay specifies the delay, in seconds, before writing the hibernation image to disk and powering off memory for Standby.

If you need to set in sleep mode and turn on the standby mode

Code:
sudo pmset -a standby 1
You can change the time you want your laptop to wait before going into hibernate mode
Code:
sudo pmset -a standbydelay number of seconds

sudo pmset -a standby 1

Ah that explains it all.

However, as the very article states, the default setting is ON. How come my mba isnt set to default?

Is there another way of enabling standby other than the terminal codes?

I really want to figure that out. What would be the regular user, little kid-old people way for turning that on?

Not sure why it isn't set to default.

Mine is set to 1 and my delay is 4200.

That happened to me once (it wouldn't go into deep sleep). Try restarting it and see if that helps. A reboot did the trick. If that doesn't work, try resetting the SMC.

http://support.apple.com/kb/ht3964

I think what is happening is that something is causing your Mac to think that something is plugged into the USB port and is active. That can prevent your Mac from going into deep sleep mode. Do you have anything plugged in? If so, unplug it and try again.

Ideally, the Mac should drop into deep sleep mode after 70 minutes. Over a typical night, it loses about 3% of the battery.

Nothing is connected, no.

The only thing that could be considered a little bit strange is a program called PARAGON NTFS, which enables mac to read ntfs partitions.

Could that be the cause?

I don't know. Perhaps it is causing the Mac to think something is installed. Maybe try deactivating it and see if it goes into deep sleep.

So there's no way the standby could be disabled by a regular change in system prefs, for example?

It has to be something I installed?

Damn even with the terminal command switching the standby from 0 to 1, no change at all.

I cant believe im gonna have to reinstal lion..

Could any of you guys who own a macbook air with the standby feature check out the pmset -g to find out the parameters?

Hello!

I've just discovered that macbook airs have this amazing feature that saves lots of battery when in sleep mode.

However I've noticed that mine doesn't perform as it should.

I charged the battery to 100% and closed the lid. Next morning the battery had dropped to 88%.

The standby feature tells that, when in sleep mode, after one hour, macbook air will go into standby mode and then its battery will last 30 days.

I've run the command "pmset -g" and here's the following:

Active Profiles:
Battery Power -1*
AC Power -1
Currently 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

I see that the "standby" is 0. Shouldn't it be another number?

Please, any tip is great!

Ive got same Problem

Thats my data on "pmset -g custom"

Id like to setup specially the Battery Power Management!

Battery Power:
lidwake 1
panicrestart 15
standbydelay 30
standby 0
ttyskeepawake 1
hibernatemode 25
hibernatefile /var/vm/sleepimage
displaysleep 5
sleep 5
acwake 0
halfdim 1
lessbright 1
disksleep 5
AC Power:
lidwake 1
panicrestart 15
standbydelay 4200
standby 2
ttyskeepawake 1
hibernatemode 25
hibernatefile /var/vm/sleepimage
womp 1
displaysleep 15
networkoversleep 0
sleep 0
acwake 0
halfdim 1
disksleep 10

I read that it should go to sleep and after an hour to hibernate! I Tried hibernate 25 & 3. Tried with standby 1 & 2.

Hoping to get help, u can't find anything on apple.com or on other sites!

Ive done lots of testing and in my case, it worked with the following:

Active Profiles:
Battery Power -1*
AC Power -1
Currently in use:
standbydelay 1800
standby 1
halfdim 1
panicrestart 157680000
hibernatefile /var/vm/sleepimage
disksleep 5
sleep 10
hibernatemode 3
ttyskeepawake 1
displaysleep 5
acwake 0
lidwake 1


That means after it goes to sleep mode, it will take 1800 secs or 30 min to go into standby mode.

I've been having issues with my MBA going to sleep when I close the lid (not always, but it happened maybe 6 times this past week). Normally, the unit goes quiet, but those 5-6 times, the fans kept on running, and the only way I was able to get it to go to sleep was to restart it first. Any ideas?


Decided to have a look see, and here is mine:


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 0 (imposed by 47)
hibernatemode 3
ttyskeepawake 1
displaysleep 8
acwake 0
lidwake 1

Can anyone explain the bolded "sleep" line to me?
