Thats right. With or without safe sleep enabled (as described and instructioned here) it takes a good 30 seconds for my MacBook to go to sleep. This is not right. I have tried:

a) Turning off safe sleep. It takes the same 30 seconds to go to sleep.
b) Running AppleJack.
c) Re-installing the 10.4.8 COMBO updater

There must be a way to fix this as it is really pissing me off. Please help me.

This is a Black MacBook CD 2GHz 2GB RAM 80GB HDD (with ~10GB Free)

Please please please help

Jeff

You could always deactivate Safe Sleep. Open Terminal, and type in:

sudo pmset -a hibernatemode 0

With no need to Restart.

or - for fuller Undo, type in:

sudo nvram "use-nvramrc?"=false

and enter Password, and then Restart.

[Safe Sleep is only worth employing if the battery is depleted, or the battery's drained but you want to unplug the MacBook to move it to another location. It doesn't seem like a good replacement for Regular Sleep, which is both fast and energy efficient].

cheers,

ClockWork, I dont mean to be rude, but can you read?!

I did say in my original post that I have tried:

"a) Turning off safe sleep. It takes the same 30 seconds to go to sleep.
b) Running AppleJack.
c) Re-installing the 10.4.8 COMBO updater"

Yes - I did read that. It's just that you didn't mention how you turned off Safe Sleep, nor if you performed a Clean Install of Mac OS 10.4.8 - (you mention that you reinstalled the combo update).

Have you tried the second command in the Terminal ?

cw

my powerbook takes about twenty second to sleep when plugged into an external display...

man I wish it took me 30 seconds to go to sleep

I actually did give a link to the osxhints article, tho it could have been my explaination as i was tired and i explained it wrong.

Anyways, everything aside, yes i did try the second command with no luck whatsoever. (and yes i did the first to)

Jeff

So essentially, it sounds like it's ignoring the command. Try opening Terminal again and typing this:

pmset -g | grep hibernatemode

then hit your return key - and the next line should come up with:

hibernatemode 0 - or perhaps: hibernatemode 3 - which instantly tells you if it activated or not - as: hibernatemode 0 must be Safe Sleep "off".

Using this command, do you see hibernatemode 0 ?

Okay - here's a really odd little thought and there's no way to insure it will work.

If the Tiger System takes 30 seconds to write the content of the RAM to the VM image, what would happen if there was no RAM Modules inside to do so ?

If you keyed in:

sudo pmset -a hibernatemode 0
sudo nvram "use-nvramrc?"=false

into the Terminal again, and then Shut Down the book instead of Restarting it, could it write RAM content to VM if there was no RAM there?

In other words, run the Command again, Shut Down completely, pull the AC Power Cord and the battery, and then remove the RAM Modules.

Plug back into power minus the battery, restart into nothing, and then force it to Shutdown again. Pull out the AC Power Cord.

Then reinstall the RAM Modules, the battery, and the AC Power Plug, and start her up again.

On full start up, delete /private var vm sleepimage

You might want to try completely shutting the Book down again, and removing Power, Battery, RAM Modules, Starting up into nothing, Shutting down, reinstalling RAM, Battery, Power etc - and then Start her up again.

Then test the speed of Safe Sleep.

Hi CW. I have checked what the sleep I am in and these are my results:

I am yet to to try that =false command and shutdown the computer and follow the procedure you said as I need to send an email first. I'll let you know how I go.

Thanks

Jeff.

And I tried the other stuff you suggested and it too does not work CW. Any more suggestions anyone?!!!

Well - it was a shot in the dark.

Following off from hibernatemode, there is a Dashboard Widget called: Deep Sleep - free I believe, which might be worth having a play around with instead of mucking around in the Terminal and coming to no conclusions.

To reclaim the drive space used up by the copy of your system’s RAM, it's back into Terminal, to type:

cd /var/vm - hit return key, then:
sudo rm sleepimage - and hit the return key, plus providing your password when asked, and Restart.

Then have a play around with the Deep Sleep Dashboard Widget.

If nothing else works, then I suppose your Macbook is behaving the way it's supposed to after Safe Sleep was activated.

See here:


As the guy babbles away about the cool Safe Sleep fuction on his Macbook, I'm counting 24 seconds for his Macbook to Sleep, so if this is the norm - then I suppose... this is the norm, and perhaps only a Clean Install of Tiger will truly wipe out Safe Sleep, in your particular case.

cw

I have (and have had) safe sleed disabled for a week or two now, and I sleep the computer multiple times a day. There is no 'sleepimage' there because safe sleep is disabled! So I have no idea what the feck is going on! This is really starting to piss me off >_<

Open Terminal and type in:

pmset -g

and hit return key - then copy / paste here, what it comes back with.

Also, if you continue to end all your posts with: this is really beginning to shit / piss me off, I'll quit trying to help you out, as you're starting to sound like a whinging petulant child.

PMU Reset:

1. Turn the Macbook Off.
2. Disconnect the AC Adapter and remove the Macbook's battery.
3. Press and hold down the power button for 5 seconds and then release the button.
4. Reconnect the battery and AC Adapter.
5. Press the Power button to restart the computer.

When putting the Macbook to Sleep, how are you doing it?

Thats the terminal output.

Also. thats the first time i eneded my post with "this is pissing me off", probably because it is pissing me off.

Anyway, I will try the PMU reset right now. I'll let you know how it goes.

Jeff

I have tried a PMU Reset. Nothing. Also, I put my macbook to sleep in a variety of ways. Closing the lid, Selecting Sleep from the Apple Menu, Pressing the sleep button on the login window when there is no user logges in. All achieve the same results.
