Sperry1988,
The system preferences can vary but worst I've seen was about 15 seconds. If it has been brought up before in the same sesion it will be about 3-4 seconds, which I would say is acceptable.
Regarding the safe sleep mode: Is there a way this can be turned off via terminal? I can see the logic behind it but for me I would rather have it off.
I haven't really got an outrageous number of programs on the laptop. Maybe 15? I have considered taking it to Apple but I am a little hesitant as I don't want to be the typical guy who complains his computer is slow.
Oh and no clicking from the drive
Thanks
The following is a list of things found in various post here on the sleep mode; I cannot give credit where it is due, as I don't remember where I got the info, but thanks to those who contributed!
Sleep settings
Files
All changes made through pmset are saved in a persistent preferences file (per-system, not per-user) at
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
Scheduled power on/off events are stored separately in
/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
pmset modifies the same file that System Preferences Energy Saver modifies.
hibernatemode = 0 (binary 0000) by default on supported desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory; the system will lose context on power loss. This is, historically, plain old sleep.
hibernatemode = 3 (binary 0011) by default on supported portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.
hibernatemode = 25 (binary 0001 1001) is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.
Open a Terminal shell (in the /Applications/Utilities folder)
pmset -g
will list all the current power settings/device settings.
1. set hibernate mode to 0
sudo pmset -a hibernatemode 0
hibernationmode 0 is normal sleep, data kept in ram, nothing written to disk
2. delete the unnecessary sleep file (since hibernate is disabled) to regain disk space equal to memory (saves the same amount of disk space as your RAM, eg. 8 GBs, valuable on an SSD),
You can use the Go to folder menu to delete the file, found in the /var/vm/ folder, and named sleepimage. Reboot and simply delete that file,. Or use this:
sudo rm /var/vm/sleepimage or sudo rm /private/var/vm/sleepimage
The sleep image file is actually in /Private/var/vm/ but /var/vm/ is a symbolic link to that location.
Optional: Create a blanked zero-byte file so the OS cannot rewrite the file:
sudo touch /private/var/vm/sleepimage
Make the file immutable:
sudo chflags uchg /private/var/vm/sleepimage
3. If pmset -g shows: autopoweroff**1,
disable this automatic hibernation mode (happens even if hibernation mode is set to 0 on the new Mac mini 2012 and iMac)
sudo pmset -a autopoweroff 0
4. set the safe sleep timer (standbydelay) to 20 hours, default is 4200
sudo pmset -a standbydelay 72000
5. sudo pmset -a standby 0
While researching this, I noticed that bit 3 of hibernatemode encourages the dynamic pager to page out inactive pages prior to hibernation. So this appears to be why I have swap used after sleeping (even though my hibernatemode is 0, so bit 3 is off). I disabled this new, possibly buggy behavior by switching off standby: sudo pmset -a standby 0
