Macbook Pro hibernation

Someone asked a while back about changing batteries on a MacBook Pro in sleep mode and whether it hibernated and preserved the sleep state when you removed the battery without having the power cord plugged in.

The answer is that it does. When you power it on with the changed battery in place it boots quickly to where you were prior to sleep but it loads the memory state from disk. The screen is drawn in grey during this process.

Which is also why it's longer in entering sleep mode, compared to older machines (where this was instant).

When you close the screen, the "sleep light" switches instantly, but if you look closer, it stays constantly at max. light for many seconds (while the machine actually doesn't sleep at all, writing your Gigabyte of memory state on disk) and only after this the fan tuns off and the "vanishing light" appears.

OK, often times the fan is not on anyway at the beginning, but this was only to comfort those poor ones that don't own a MBP ;-)

Yay! Proper hibernation, the useful way.

Are the settings for hibernation visible in the energy saver control?

Poot. And from HervÈ's post, it sounds like hibernate _replaces_ sleep mode - is that right?

Does Patrick Stein's Hibernate (http://www.jinx.de/weblog/weblog.html) give you a choice of sleep/hibernate, like it does for my G4 PB12"?

The way hibernate works is that it sleeps as normal (barring the write-to-memory pause as it dozes off) but if the battery drains completely - and the machine shuts off - then when it next gets power it will turn on and 'boot' from the saved state.

So the only difference is a longer pause before sleeping and 'automatic' hibernation if you run out of battery completely. Seems like the most user-friendly way of managing it.

Comprendez. Very useful in that case.

Doesn't help if you want to switch out the battery before the machine decides to move into hibernation, though. Or if you know you're going to be away from power for a couple of days and want to switch to hibernate intentionally.

Don't know. I'm happy with the behavior at present. If I don't replace the battery when in sleep mode then it starts up instantaneously when opening the lid. If I've replaced the battery it reloads saved state from disk.

Seems fair to me.

All this means is it'll take some n extra seconds to startup again. Need to change the battery. Close lid. Make sure sleep light is blinking. Change battery. Open lid. Back to where you left off.

Oh - does this mean that I've misunderstood?

Are you saying that the 'Boko always save state to disk anyway, then sleeps, then hibernate if necessary? So any power interruption just results in un-hibernation instead of a cold boot.

The way hibernate works is that it sleeps as normal (barring the write-to-memory pause as it dozes off)

But does it wake up as fast as the G4 PowerBook, ie nearly instantly?

I think that's far more important than an extra few seconds to get to sleep.

Following up but having unplugged the G4s keyboard out of the macbook, the keyboard now works again.

I would hope it doesn't write the whole gigabyte. Much of it will be read-only data (program code, shared libraries) and quite likely other parts of it will already have up-to-date copies in swap space.

I think the control must be simpler than that, something like if it's put to sleep on battery, it'll hibernate - else on mains it'll just sleep, otherwise how the heck does it know that the battery is going to be removed so as to hibernate rather than just sleep?

I think it's a case of the former. If there's no battery reserve, it'll hibernate (even on mains) whereas if there is, it'll just sleep whilst on mains. If on battery only, it'll hibernate regardless in case of removal.

No it will continue saving, then wake up.

It does, I put my MacBook to sleep yesterday evening with 2hrs battery left, it hibernated, I removed the battery as soon as it entered the usual pulsing sleep, replaced battery a few mins later, and it awoke from the hibernated state on the HD.

Maybe I wasn't clear. What I would want is sometimes for it to save the state and then sleep, and sometimes for it to save the state and then turn off immediately, so as not to run the battery down. You can presumably achieve the effect of the latter by putting it to sleep and then removing and replacing the battery.

What might be useful - in order to avoid the battery-removal hack - would be for the power-button menu to include an option to hibernate immediately.

This should have no effect on the current behaviour, so now you have three scenarios:

1. No hibernation:
User closes lid (or whatever) to sleep the machine. It saves its state in preparation for hibernation (just in case). User wakes it up before battery runs out.

2. Automatic hibernation:
User closes lid (or whatever) to sleep the machine. It saves its state in preparation for hibernation (just in case). Battery runs out. When user re-supplies power, it boots from its saved state.

3. Manual hibernation:
User elects to hibernate manually (power, then H key?). It saves its state and then turns off. When user re-supplies power, it boots from its saved state.

That seems to be the best of both worlds to me.

I appear to be stuck in the middle. My iBook is (presumably) not new enough to work with the first suggestion, but is not old enough to work with the second.

Oh well. To be honest, I am not that fussed unless there is a third party solution that works as seamlessly as the Apple one. I'm happy to wait until I can afford a new machine ;)

It's only shite on Windows because Windows is rubbish at cold-starting devices that the OS thinks are still warm, IYSWIM. OS failure, not a hardware problem as such.

Hibernation works perfectly on my PB12", in an unsupported fashion.

Only time the batteries ran out on me was when it went away for such a long time it should have been shutdown anyway. My TiBook comfortably sleeps for over a week.

Contrast that to the complete inability of any Windows computer to recover from hibernation with any degree of reliability.... I'd rather use sleep, unless Apple have got a working version. I recall they pulled hibernation from 10.4 as it didn't work...

Blimey. After a little experimenting today, this is _exactly_ how my PB12" has been behaving ever since I used Patrick Stein's Hibernate.

That (for those of us with 'Bokos that support it) offers normal (sleep only), Intel-like (saves state then sleeps, then hibernates), and hibernate-only.

I'd set it to sleep+hibernate, and it's been working just as Ian and Herve describe for the last six months - without me even being aware of it! D'oh.

Well, it depends on how charged the battery was when you put it to sleep. I left mine for just over a day, and had no end of trouble getting it to restore the time afterwards (the usual ntp wouldn't do it, because it was "too wrong").

Fortunately, I've never really used Windows.

Umm.. do what? It is a rare thing that a windows machine fails to recover from hibernation in my experience.
I would classify it as completely reliable.

The MB & MBPs still sleep, they just save the state to HD for hibernation in case of a total power loss [1], that also 'just works'. It wasn't until Ians post I'd even twigged the MacBook was also hibernating.

This year's Dell unhibernates pretty reliably, once I'd got rid of the Dell power-saving control panel. XP.

The tiny Fujitsu that I have here (1999) unhibernates very well under Win2000, but not XP. Except if you want to use a network after waking up, in which case you're SOL. Works better under Win98, but kept trashing its C: drive.

The four Thinkpads I've had over the last few years have slept+woken okay (except one of them), but none have unhibernated with better than 25% reliability. 2000 and XP.

Powerbook: It Just Works, even the unofficial hibernate. It _really_ helps when the OS and all hardware is designed+implemented by one vendor.

Same here. I think sleep (standby) relies on hardware support while hibernate doesn't, which may be something to do with it. Other than changing hardware while it's in hibernation I can't think of a time Windows Hibernate hasn't worked for me.

The only time it's screwed up for me was if I've removed a piece of hardware, though my uncle's laptop won't sleep very well - but that could be another issue.

I've never had one Windows computer (4 Compaqs, all stock, no weird PCI cards) that could recover from Hibernation reliably. They would all freeze when trying to load the hibernation file, then you'd have to do a "last known good" or "Safe boot" to get them running. And loose the hibernation data. Also seen the same thing on numerous other PCs.

Sleep however, works perfectly. I've left my PC sleeping for days at a time, wakes within a few secs, just works.

It is amazing how mileage varies for these things. I have never had one computer (including compaqs, dells, HPs and all maner of others) that couldn't wake from hibernation properly.
However sleep is a hit and miss thing, and i have never had a pc that woke from sleep in a few seconds, it has always been 10s of seconds.

Actually I think the mesh here on my left will wake reasonably quickly (maybe even under 10 seconds). The HP table will if it has recently gone to sleep, but if not you are talking at least 20-30 seconds until you are up and running (in fact hibernate is faster). The dell is pretty slow at sleep too.
The older dell will wake quite quickly but that gets reghosted on a weekly basis.

There is a problem hibernating on machines that have over 2Gb ram though (or is it 1Gb..)

My homebuilt Shuttle PC sleeps fine but doesn't wake up to key presses. I have to waggle the mouse to waken it, probably because I use a USB keyboard.

Duh!!!

It used to be slow on most of my windows pc's - until I realised that the swapfile has to be bigger than the installed ram. If it isn't, it'll write the memory to disk and take much longer to sleep than usual (usually about 2 minutes in most cases).

I -think- I saw that on my MacBook Pro once. Certainly remember switching on two finger-clicking after being confused it wasn't one, and thinking I'd done it before. Can't be -absolutely- sure though.

Anyone else getting this after removing a battery in hibernation mode?

Not sure what triggered it, but I doubt it was this (in my case at least). The only time I've removed the battery was to swap it for the new one Apple sent in the recent recall, and the two finger-click problem occurred before that.

Cheers,
Ian

Yes, I found it happened when I tested it with my MBP at lunchtime - I wondered why the heck it had screwed up.

Bug report time.

Umm.. do what? It is a rare thing that a windows machine fails to recover from hibernation in my experience.
I would classify it as completely reliable.

I have enough issues waking up my W2K laptop from sleeping. There's no way I'm going to risk hibernation.

Sleep I have had trouble with. Hibernation has been pretty problem free.

Same here. I think sleep (standby) relies on hardware support while hibernate doesn't, which may be something to do with it. Other than changing hardware while it's in hibernation I can't think of a time Windows Hibernate hasn't worked for me.

indeed nasty pc hibinates fine, it sleeps mostly okay as well gets it knickers in a twist over the wireless network but well it's windows....
