Is anyone else finding that their mini falls asleep and won't wake up? I am tired of hard booting this little thing and wondering if there is a fix. Tried the "sudo" technique in Terminal; however, it still happens. Any help is appreciated.

Thanks

Do you have USB Legacy support disabled in the BIOS?

I've got the same problem (now fixed - see update below). USB Legacy is off. I installed 10.5.7 Combo, restarted in safe mode, repaired permissions, then reinstalled DellEFI 1.1 and AboutThisMac.pkg without issue, and everything seemed fine upon restart. However, the machine is only waking up very rarely after it goes to sleep.

I reran the entire procedure and reinstalled the 10.5.7 combo and DellEFI (and decided to leave AboutThisMac.pkg until after solving this). No change.

I notice that when I put the machine to sleep (whether by closing the lid or by selecting "sleep" from the Apple menu) the LED on the Mini 9 is no longer pulsating/breathing the way it used to. Indeed, it seems that the machine is remaining active, and hanging before it actually gets to sleep - it still gets hot. Yet it still won't wake.

I'll try the latest DellEFI beta now.

What's the "sudo technique" by the way?

-- Update:

Installing DellEFI 1.2b5 appears to have fixed everything, as well as giving me the somewhat prettier (and I think faster, though that could be illusory) new Chameleon launcher.

As part of the process, I removed the custom dsdt file, rebooted and built a new one. I think I had done this with 1.1 too, but I'm not certain now I think about it, so you might want to try this with 1.1 first. Meklort commented yesterday that he thought rebuilding the dsdt would not be necessary, however.

I'm having the same problem since installing 10.5.7. Im currently using DellEFI 1.1. Can you simply run the DellEFI 1.2a5 with the preset settings and be good to go? Are there any known downsides to 1.2a5 at this point?

Here's what worked for me: Disabling 'Hibernate' mode in DellEFI. I'm still using the 1.1 final and always 'verbose boot'...

I noticed that no matter what settings I have the /var/vm/sleepimage used for hibernation always comes up corrupt. It's a fact of life that some early Powerbooks didn't support hibernation and this seems to be the case with Mini9s. So switch it off.

- Use DellEFI, run Custom and do it from there, or,

- Use the 'SmartSleep' prefPane -- search for the current version on MacUpdate.com

...to disable Hibernation... once I did that I could just sleep/wake by any means I'd use in any other laptop (clamshell close/open, keystroke, menu item, etc).

Hibernation used to be dicey even with the APPL laptops, that's why SmartSleep was made and why some users (me included) prefer to disable it entirely.

I believe DellEFI turns hibernation off by default - if you've got it on, I think it's because you turned it on yourself. It even clearly says "Enable Hibernate (not recommended)" by the normally-unchecked option.

This is a known limitation of our hackintoshes - Hibernate (and Safe Sleep) doesn't work at this time, hence the default of disabling it.

The nature of Smart Sleep is that it saves memory in both RAM and on the hard disk, so that if there's still battery life left, you can wake up instantly using the RAM, and if not, you can wake with minimal delays by reloading from disk when there's power again. This has the downside that it always takes up an amount of disk space approximately equal to the amount of RAM you have. Since the latter option does not work on the Mini 9, it's disabled, and you're left with the former option - but if your battery runs flat, your machine will have to do a full reboot next startup.

Again, this is unnecessary, just use DellEFI's options.

I've never known any real Mac on which this doesn't work reliably - certainly nothing in the post-Intel switch days, and I'm an Apple-certified Mac support guy (not for Apple, but where I work). An occasional failure can happen, as with anything, but it's rare. Even my old early-2004 Powerbook can use Safe Sleep without any problem, though it required a hack to enable it - Apple only started widely enabling Safe Sleep in early 2005. Hibernation on really old Macs (around 1999-2001) was usually fine, though you're right, it wasn't 100%.

I'm curious... why do you use verbose boot normally? There are valid reasons, I'm not disputing that, but for most users it's only useful for testing and diagnostic purposes... and can be enabled on a per-boot basis with the -v switch at the boot prompt if needed.

Just got mine working - Vostro A90, 10.5.7, 1.2a5, disabled Legacy USB in BIOS - that fixed it - sleeps and wake in all the usual ways... so far...
