Click here to return to the 'Deep Sleep - Put new laptops into hibernation mode' hint

Deepin OS is ranked 21st while macOS is ranked 24th. Future islands wave like home rar. The most important reason people chose Deepin OS is: The desktop interface and apps feature an intuitive and elegant design. Moving around, sharing and searching, etc. Has become simply a joyful experience. The macosxhints Rating: Score: 10 out of 10 Developer: Matthieu Beaumel Price: Free (Open Source) This is the Pick of the Week for the week of October 9th We've run a few hints here about Apple's Safe Sleep mode, available on all portable Macs since the fall of 2005 (and certain older machines, as explained in this hint).

I'd give this utility a 9.5 as it stands because of the way the administrative password requirement is handled.
Mac OS typically presents both a username and password field when requesting administrative privileges. This behavior allows someone to run with standard user privileges day-to-day but also provide administrative privileges when necessary.
Speaking more generally, I'm concerned that a lot of Mac developers (I'm looking at you Google) are unintentionally walking us backward into the current Microsoft Windows situation where the Run As feature doesn't always quite work as it should.

Starting from version 0.8 (released yesterday), the widget works on non-administrator accounts.
Thanks for your feedback.

if i am not wrong, everytime you close the lid of macbook, it enter safe sleep mode. so if you need to swap battery, just close the lid, wait until the sleep light started to pulse, and you are safe to take out the battery, without any help from 3rd party software.

Yes, true. Bad example I blame on 2am writing time :). Hence, mostly useful for just those times you want it in hibernate mode without yanking the battery.

With the machine in sleep mode, and the battery removed, what's keeping the machine from being powerless?

A small back-up battery, maybe in the form of a condensator.
To clarify, with Powerbooks (back at least to the Pismo) and MacBooks Pro (MacBook Pros ?) when you put them to sleep, you have maybe one minute to change the battery. The maschine will not lose power, it will not go into deep sleep. When you open it up again, it just wakes from sleep normally.

The Wallstreet, and if i recall correctly the Pismo too, have dual battery bays (the CD drive bay is also a battery bay). Even so, it is true that the PRAM battery can power main RAM for short periods of time, if all main batteries are removed.

No, when you close the MacBook lid it goes into normal sleep. The MacBook manual says to shut down before swapping batteries.
If you're running and the battery gets very low, it goes into deep sleep. I don't know if it can switch from normal sleep directly to deep sleep, but I suspect not. (I've put mine to normal sleep, then had the battery run out. In that situation, it has to reboot from scratch.)

This isn't true. I just did it myself to prove it. Steps taken, with a never-tweaked MacBook:

1. Run some apps.
2. Close the lid.
3. Wait for sleep light to start blinking (it's solid while RAM is written to disk).
4. Remove power cord.
5. Turn machine over, remove battery.
6. Wait a few minutes, hours, days, whatever.
7. Put battery back in, plug power in.
8. Open lid and touch power button.

When you do this, you'll see that the machine doesn't boot from a power-off condition. Instead you see your grayed-out-screen and an odd progress indicator as the machine reads RAM from disk. After slightly longer than usual wake-from-sleep, you're right back where you were before the sleep/hibernate trick.
-rob.

I agree--the 'safe sleep' is present by default, and noticeable on my MacBook. If you put it to sleep there is a 30-60 second delay between when the screen turns off and when the HD spins down--during this you will notice the sleep LED comes on solid white but doesn't blink. I presume this is when the RAM gets written to disk.
One problem I've had, though--I've caused a kernel panic on several occasions by triggering the sudden motion sensor while it's writing RAM to disk. It's a little tricky--I close the lid, think it's asleep, drop it onto a pillow on the floor, and 8 hours later it's blazing hot and with the KP screen o' death visible on the non-backlit LCD. Anyone else ever done that?

Hmm. Ordinarily I skip steps 5-7, and I never have a progress bar when I open the lid. This and the info in the MacBook manual were my sources for my comment.
Perhaps things work this way. When you close the lid, it writes the RAM image but goes into normal sleep. On a critical batter condition, it goes to deep sleep. On wake, if we were in normal sleep, we just start running again. But if we were in deep sleep, we restore the RAM image.

How did you get a 1.67Ghz 12' PowerBook? Apple certainly never made one.

sorry. 1.5GHz

Damn, I thought you may have overclocked it or something.. :-)

PowerBooks have an internal battery which will maintain power for about five minutes, allowing batteries to be hot-swapped.

Or maybe not.. wherever I read that seems to have disappeared. Don't try this at home! :)

Rockys revolution mac os. https://caesars-money-pw-real-nerdslots-win-slots.peatix.com. have the backup battery. All except the 12' do. That's why you cannot replace a battery in a 12' without powering down, but you can in any other powerbook.

I upgraded from an old 12' Powerbook G4 to a new MacBook Pro.. I really notice how much longer the MBP takes to sleep when I close the lid. My old powerbook would sleep in under 3 seconds.. the MBP takes at least 20 seconds!
I really don't like this new feature on the MacBook Pro, and I don't want it to write its memory to disk each time I close the lid. I rarely, if ever, leave the computer in sleep mode and let the battery drain.. I use my computer all day, everyday.
How do I turn off the deep sleep feature? I want it to sleep faster than 20+ seconds! I wish it would work more like my old powerbook did. [shrug]
thanks,
Kelly

Greetings.
If you want to disable the default 'fall back to hibernation if ever the battery was to run out of power' behaviour (and therefore make your computer enter sleep quickly), please do the following.
Open up a terminal, and type the following command:
sudo pmset -a hibernatemode 0
You will need to enter an administrator password.

Woe be ye who clicks on this widget more than once!
Sometimes, you know how Dashboard widgets take a moment or two to swap into RAM? Well, I clicked the 'Deep Sleep' widget a few times, assuming that it was 'coming up'. Well, it registered all of those clicks, and did a deep sleep for each one.
So my Mac went to deep sleep. Then I woke it up. It then immediately went into deep sleep again. And again. And again. Once for each click I did.
But that's not all! Remember, the way the 'Deep Sleep' widget works is to check what the 'normal' sleep mode is, remember that, set 'deep sleep' mode, sleep, then restore the remembered 'normal' mode once the Mac wakes back up again. Well, since the widget was being invoked several times in rapid succession, it didn't have time to restore the default setting of 3 (safe sleep) and the subsequent invocations remembered 1 (deep sleep). So I got stuck in 'deep sleep' mode every time I did a normal sleep.
A quick trip to the command line and pmset was able to get me back happy again.
But yeeesh! That'll teach me to be impatient with my widgets!
