Sleep and Wake problems under Lion

I called Apple for help and this is what worked for me. I have a Macbook Pro and am running Lion.

Shut down the computer. With the power adapter plugged in, hold down these keys together for 4 seconds: Shift, Control, Option, and Power. You will not see anything happen- the screen will still be black. Now power up. Go into System Preferences, Energy Saver, and put the Computer Sleep and Display Sleep settings on 1 min. Wait a minute and let it fall asleep. Try waking it up to see if it is ok now. If it’s all good, set it factory default or whatever you want and hopefully all continues to be well. Good luck!

I was exactly having your problem. This did it for me:

The similar problem (wake up after sleep/; iMac i5, Lion) was caused by the empty USB cable plugged for charging my smartphone. Unplug the USB cable and problem was dissapear.

Turns out my issue can be worked around by leaving the Plantronics USB receiver unplugged. Without that in my Cinema Display it wakes up perfectly. Was never a problem with Snow Leopard but Lion clearly doesn't like it.

The only method I've discovered to have decent network connect is the following:

system prefs/network pane reorder that ethernet is top most and wifi assuming you have airport is second. Also turn airport on and point it at your network and connect.

Once you wake from sleep you'll get connected everytime but it will take about 15 seconds longer than using Snow Leopard.

I've also noticed a strange new sleep/wake behaviour.

Specs:

MacPro 3,1 (2008)

Apple HD5770 graphics

2 x Dell 24" Ultrasharp monitors - one on DVI and one on MDP with Apple adapter

OSX Lion (fully updated)

Recently I've noticed that my Mac doesn't stay asleep. I can put it to sleep with the button on the front of the case, but shortly after going to sleep, the Mac wakes up.

Reading the syslog I noticed that it was a USB event waking it up and traced it to my Ultrasharp monitor that I was using as a USB card reader. What happens now is that when the Mac goes to sleep, the monitors turn off (power down). This causes the USB reader to power down and shows up as a USB event causing the Mac to wake up again.

This is very different to a couple of weeks ago, where my monitors didn't power off when the Mac went to sleep. Was there an update to the graphics driver or power control software that would cause my monitors to power-down instead of just entering sleep mode? any way to revert back to the old way of just putting my screens to sleep?

very strange.

I am having the exact same issue that you are describing. I have not been able to figure out a solution at all.

Have you ever solved this mystery?

Your description is perfect, I was trying to put it into words to write something, but I cannot improve upon your very accurate descritpion.

My MacBook Pro is ony a few months old, and I have had several such mysteries. Not real happy about about it all.

One other issue I frequently have is really slow internet Web page loading. Makes me furious. My iPad works briskly on the same pages, but the MacBook gets really stupid sometimes.

Buyers remorse has set in, but I still prefer Macs, though two MacBooks have been killed by third party products so far. One was killed by Simpletech memory modules, and another by an external Seagate USB hard drive. Neither company would assume any responsibility. Needless to say, I will never purchase products from either of these companies again.

Sewer Sleuth

Slightly different for me with Lion 10.7.2

When I come back to my sleeping iMac and move the mouse, the screen appears exactly as it was when I left it, but as I start to move the mouse about, I'm kind of rubbing out (like a pencil eraser) the screen with 1cm squares and underneath is the normal grey login screen. I have to rub out enough so that I can see my username, then click on it to get back in.

It's not right.

That is exactly what is happening on my iMac 2.8 GHz core 2 duo with 10.7.3.

I am having very similar sleep problems and have a few very clunky workarounds and observations. Observations: closing the clamshell on my MBPro will often fail to put the computer to sleep. The LED stays solid and does not throb, the fan spins and the CPU stays active. It will get hot if this happens for a while. This is probably only happening with the power cord plugged in

I have exactly that issue. After some reading up on it I have fixed it by removing unused printers from CUPS, and that helped for a short while. Now the problem came back, I removed all remaining printers from CUPS, and it seems fine again now.

Not sure if printing would still work though, I don't really understand the CUPS thing, and I shouldn't have to. Hacking workarounds for an annoying issue.

I have a similar problem with my 2008 MBP, unless I put it to sleep manually (via OS) it will routinely die (screen black but computer still humming slightly) when I wake it up. It's normally ok for about 3 seconds after having woken up, but because it's intermittent I can't work out if it's only when I move the mouse. I sometimes get the feeling that it happens when I click on an application in the dock.

The computer is left with the screen black but still slightly humming. The only way to get out of this state is to hold down the power button and do a hard reboot. Sometimes it won't even boot up again (starts spinning but no LED on front and no startup chime) and I have to disconnect the power cable and/or battery.

ANOTHER FIX FOR THE FAIL TO WAKE FROM SLEEP/BLACK SCREEN ON STARTUP PROBLEM

I too had the same problem with my MacBook Pro (July 2009) running 10.7.3 - lapsing to a non responsive black screen after waking from sleep and then after startup even when using safe boot/recovery boot/and alternate disk boot modes- all failing to solve the problem.

What worked was purely a software fix by deleting corrupted caches.

Using the TARGET DISK METHOD after restarting in target disk mode (conect to second mac via a firewire cable and restart holding down the "T" key) on a second mac I went to the following location

<System/Library/Caches/com.apple.kext.caches/Startup> and deletied all the caches that had been active recently which were

<kernelcache>,

<IOKitPersonalities_x86_64.ioplist.gz>, and

<KextPropertyValues_OSBundleHelper_x86_64.plist.gz>.

I then ejected the MacBook Pro from target disk mode and restarted. MacBook Pro now performing flawlessly.

I suspect there was a kernel panic involved. The MacBook Pro will want to reindex after this process. I would also reset the PRAM and repair disk permissions with Apple's Disk Utility (already loaded on all Macs).

Well in the end I took it to the Apple store and got the Logic Board replaced... Works fine now except for a new WiFi issue...

my first iMac (27" late 2012) exhibited problem with the fan going on full blast upon connecting to power, quiet when the machine was booted, and on full blast again when the machine was off. called apple, and got a replacement.

I am now on my third replacement iMac, the last two are exhibiting identical issue with sleep: the machines will go to sleep and will not wake up, and in addition the power button is disabled, i.e. pressing the power button will not restart the machine.

I am guessing that the SMC crashed, as the only course of recovery is to reset the SMC by removing power, pressing the power button for a while, and attempting to restart (does not work all the time, so I sometimes have to repeat the SMC reset procedure).

after doing some research on the net, I found how to view the hibernate mode, and saw that my machine was set to hibernate mode 5, which is NOT an approved setting, see below.

I used the system pref -> energy saver and clicked restore defaults which restored the hibernatemode to 0.

HOWVER, upon plugging in a powered USB hub, the hibernate mode was automagically reset to 5.

once at hibernate mode 5, putting the machine to sleep manually exhibited the same symptoms, i.e. not wake from sleep and disabled power button.

this was done with an apple care tech on the phone, and he recommended replacing the iMac once again, and sending me a fourth replacement!

overnight I played some more with this

I reset the hibernate mode but this time to 3 and I tried a different USB hub.

hibernate mode stayed at 3 after plugging in the USB hub.

I then created a small shell script to monitor and display the hibernate mode:

function showhibernate() {

while true

do echo -n `date` " ";pmset -g|grep hibernatemode;sleep 10

done

}

and executed it overnight

this evening after I came home from work, I noticed that the hibernate mode somehow was switched from 3 to 7!?

unfortunately, I did not have the echo `date` on the first version, so I do not know when it was switched from 3 to 7.

however, the machine did wake up from sleep... (so it seems that 7 is not as bad as 5?)

I am guessing that some powered USB hubs cause unexpected changes to the hibernatemode, which in turn cause the SMC to crash, disabling the power button.

why plugging in some powered USB hubs but not others will cause the hibernatemode to switch to 5?

why hibernate mode would automagically switch from 3 to 7?

neither 5 nor 7 are documented in the man page, and the only recommended modes are 0 3 and 25:

We do not recommend modifying hibernation settings. Any changes you make are not supported. If you choose to do so anyway, we recommend using one of these three settings. For your sake and mine, please don't use anything other 0, 3, or 25.

For now I cancled the shipment of the fourth replacement, as this seems to be an issue affecting all new iMacs (and a specific USB powered hub), so that a new machine will not resolve the issue...
