I have limited space after installing osx 10.5.8. I have also finally gotten sleep to work but the sleepimage keeps taking up 1gb out of my precious hd space. Is there any way to automatically erase the sleepimage after restart from sleep?

Also, are there things to delete from the os that is safe to delete. Thanks a bunch. This forum has been a tremendous help.

Look for threads about disabling hibernation. They'll have the steps.

i have read many of the threads... and did find out about the use of the terminal to delete the sleepimage by using "sudo rm sleepimage" in terminal.

but i have to do this each time i use sleep... when i awake from sleep the sleepimage is recreated, which means i have to manually delete the sleepimage again. i just want to know how to set it up to where the sleepimage is delete automatically upon awake.
thanks.

The reason it keeps getting recreated is because you didn't do the part from those threads on setting the sleepstate. You want sleep only instead of what Windows calls hybrid sleep, which makes a memory image but then chooses to sleep instead but then has the memory image as a fallback in case the battery dies.

oh, i mistakenly put this in the regular dell mini 9 discussion... sorry. thanx for moving.

thanks for the help. i am working with OSX 10.5.8 and have hibernate turned off and set to only use sleep. I may have done something wrong where a sleepimage keeps getting recreated every time it goes into sleep mode... my setting are incorrect.

i'll have to fiddle around with the settings but i fear messing up the sleep mode as i finally have it working correctly without getting a black screen on awake. everything works well besides the sleepimage getting recreated.

go into terminal and type: sudo pmset -a hibernatemode 0

this will disable hibernation all together. after the command is executed, delete the sleepimage and reboot.

ideally, i'd like to be able to keep hibernate as an option where if it stays in sleep mode too long, hibernate will kick in to prevent complete battery drain. in this situation, the sleepimage will be created. is there a way to have the sleepimage be deleted when the computer comes out of hibernate mode? ... say using an automatic script or something.

please bear with me, i'm pretty noobish with this stuff.. thanks

What you're looking for is what's typically deep sleep in the Mac world and hybrid sleep in Windows and is the default way Macs behave. Trouble is that unless you really work at it (and some luck seems to be involved also since it works for some and doesn't for others) and you make hibernate work enabling deep sleep wouldn't accomplish anything. Otherwise the hibernate file created is junk and won't work. Problem is even if you got it working, then could automagically delete the sleepimage upon waking, you'd still be using up that 1G of SSD space each time you slept.

Which means you wouldn't be accomplishing what you say is important in your first post in this thread and not used up that 1G of SSD space.

So just set the hibernate mode as above, delete the imaage file and use just sleep and never sleep so long the battery dies

Or live with loosing the 1G of SSD space and make real hibernate work. Once you've got that you can then choose to hybrid sleep or just sleep.
