Leopard will not sleep?

Holy crap! You're right! I did a little experiment. I hooked up both of my external hard drives and set them to never sleep. I set my Leopard sleep timer to 1 min.

After 1 min, the screen went black and the solid LED light came on.
After about 3 mins, I heard both external hard drives power off.
After about 5 mins, the LED started blinking and my iMac was asleep.

Holy crap! I guess sleep does work as it's supposed to!

Thanks for the tip.

Yes mine was replaced due to the sleeping issue. My macbook would wake while the top was closed over and over. I took it to Apple five times before they replaced it. They replaced it b/c the OS itself started crashing as well. This machine, a leopard does seem to take much longer to sleep. And they changed the keys, including removing the apple sign from the command key. How sad!:(
 
Try the following...

This is one of the first bugs that haunted leopard when it came out, both the lack of sleep on its own or having trouble awaking, these are my hints all benign:
In system prefs, in energy saver, uncheck the "put to sleep hard discs when ever possible"
reset the PMU, take out the battery or disconnect your computer and press the power button for about ten seconds, then reconnect and start-up.
The following apps are known to cause the system to awake: Ape, application enhancer, techtool pro, or several haxies apps, like keyboard apps and several widgets.
You need to look at the Console logs and see what Daemons are active or restarting, I had a message reoccurring: "...respawn will restart in ten seconds" the apple forums have the solution for this but I forgot, but its a Terminal command that kills it.
Time Machine or Spotlight may wake the computer if you have not elected to exclude the system files, in other words you need to exclude your system files from the backing up or the search from spotlight,
USB and bluetooth connections are ok
in terminal type: sudo kill mdnsresponder (process ID)
If you have Cocktail, delete all caches and log files.
If I think of anything else I will post it.
 
also this...

there is a Terminal command where you force bind:
update_prebinding -force -root /
this gets rid of the restarting process, then allows the computer to sleep.
somebody also mentioned "deselect:awake for system administrator..." thats good.
 
Possible cause of sleep problem w/leopard

We had a similar issue with an iMac G5. We upgraded to Leopard and immediately had sleep issues. The system would wake on it's own after a few minutes without fail. After exhausting all possibilities we determined the Logitech wireless mouse was the culprit. I haven't tested the system with an Apple wireless mouse yet, but the Logitech was definitely the cause of the problem with this system. We attached a wired Apple mouse & keyboard and have had no problems since.

I can confirm this as well. Actually, the Logitech Control Center update fixed my issues. This one was apparently updated for Leopard compatibility, and as soon as I installed it and restarted, my sleep issues went away.

However, if I remove my external drives from the Spotlight privacy pane, the problem returns. It's a fragile balancing act, I guess.
 
Similar problem

MP with leo 10.5.2 sometime sleeps perfectly - and sometimes doesn't...
I can't figure out any specific 'scenario' when this occurs...
if I tell it to sleep it does with not problem,
and ever since the 1.1.3 EFI update I had no more 'wake-from-sleep' problems...

just this annoying thing.

I should probably reveal, however, that for some reason I am not able to reset PRAM - I press the necessary combination and nothing happens. I though EFI would fix this but it didn't and I have a feeling this is somehow connected to the sleep issue.

I saw many 'I have the same problem' responses on this thread, but who's smart enough to give us the solution?

good luck
 
Try replacing your wireless keyboard & mouse with your wired ones temporarily. If the system sleeps normally you need to try updating the software or drivers for these devices.
I solved the sleep problem on my G5 iMac in this way. I had a Kensington wireless mouse that was causing the problem.
