Sleep and Wake problems under Lion

Have a similiar problem.

Sleeping mac being woken by Apple TV.

Can access everthing perfectly but as VFMnet finds, the fans are on constant. I assumed it was the fans in the MacPro but having read this post I'm now of the opionion that it's something to do with the change apple made to Wake On Lan Access and graphics cards. Deep in the Apple documentation with this feature is that it now uses less power by not waking the displays. It seems this functionality is causing the fan(s) to stay on.

Tried all resets to no avail, so either 10.7.1 will fix (due soon I hear) or a firmware upgrade is required for the Graphics Cards.

2.66 Quad Core MacPro with ATI Radeon 4870.

My problem is slightly different but still with 'sleep'.

Clean install of Lion on a 2008 Mac Pro 2.8GHz Quad-core (12Gb RAM, NVIDIA GeForce 8800GT 512Mb plus NVIDIA GeForce GT 120 - I have 3 monitors). If I attempt to put the computer to sleep manually from the Finder menu, the system reboots and shows me a message saying it has just recovered from an error (i let it send the report to Apple). If the computer goes to sleep because of the energy saving settings then I can't wake it with the (Apple) keyboard or mouse, and the first time this happened all the fans were stuck on full speed.

I'm hoping a fix comes along soon for this.

I don't wish to further dilute the original post, but I'm also having some general issues around sleep with my system since I upgraded to Lion (though, perhaps somewhat different from what's been reported).

The main problems are that sometimes the mouse and keyboard freeze after telling my desktop Mac to go to sleep. Unplugging and replugging them doesn't help, and even attaching a different mouse to another port doesn't work. I can, however, take control via screen sharing from my laptop and control the desktop just fine. However, I have to restart it to regain mouse and keyboard control (logging out and back in doesn't help).

Second, it seems to crash when I put it to sleep at times. At night, I'll put it into sleep mode, and when I get back to it in the morning it's off, and has to be powered on and booted up (not simply awakened from sleep).

Frustrating...and definitely new since Lion.

this - unfortunately - sounds very familiar to me (Mid 2009 13" MBP):

after having been in sleep modus usb (and firewire) devices are not working any longer: e.g. keybord, but also FW disk for time machine... Also had sometimes glitches with LAN after waking up from Sleep. Mouse (bluetooth) always working.

What helped for both, USB keyboard and FW disk is: shut down device (USB Hub, FW Disk) and repower them after some seconds... odd

Defenitly new since Lion and not related to 32/64bit as I was (manually) running Snow Leopard in 64bit mode for months without problem.

I'm not really in the right forum here, but my experience seems to confirm these issues are from Lion.

I've had similar problems -- when I wake my iMac (2.4 GHz Core 2 Duo) via the iOS Remote app or via ATV2, no data will appear. The iMac wakes up, the screen is dark, but nothing works! I walk into the other room and push a button the iMac -- everything magically works, songs and albums show instantly.

I've tried restarting everything -- no luck.

Incredibly disappointing -- Apple had just finally worked out most of the bugs in the Remote app, AppleTV, and wake from sleep issues in Snow Leopard.

I have a similar issue in which the hard drives will spin down even though my computer (MacPro 1,1) is not asleep. My startup drive is an SSD, and the other four drive bays have HDDs. I have unchecked the "Put hard drive(s) to sleep when possible" in the Energy Saver preference pane. (On a side note, it's strange that this feature isn't grayed out; how does an SSD go to sleep? This is also the case with my MacBook Air.)

I wouldn't mind this behavior except that I've been experiencing kernel panic-lever issues when the computer needs to access something on the sleeping hard drive (an iTunes song, for example). I have NEVER been able to successfully wake up a sleeping hard drive in Lion. The spinning beach ball starts with the foreground app then slow starts freezing every other open app. I can Cmd+Tab to other apps, but even then the Finder eventually dies. A hard reboot is the only option.

Snow Leopard never experienced these issues. However, SL obeyed the "Put hard drive(s) to sleep when possible" setting, which seems to be the start of my problems in Lion. Like many others, I should have waited for the x.1 patch.

SSD can't, and "sudden motion sensor" can also get in the way - on your laptop.

It may be that yours and my 5 yr old 1,1 with the EFI32 will not adjust perfectly and while an OS can patch ROM code and bugs, can patch microcode, even drivers, there is only so much.

Only thing I can suggest, and don't overdue, is zap PRAM from a cold start to give the power management a nudge, do a single SMC Reset.

Last but never least: try Lion on its own if you upgraded over SL and see if it behaves.

You may have done all of that already, but in case you have not...

I find I'm having exactly the same problems, especially that I used to rely on the automatic sleep when I put the lid down; if I still have the charger connected, the mac won't go to sleep at all, so instead I have to take the charger out when closing the lid.... It's very frustrating with the high-pitched noise present all the time as well, not only does it continue to spin when I close the lid but it's now quite noticable even when I'm using the computer (which was definitely not the case with Snow Leopard)... Any suggestions for a fix?

MB Pro is not Mac Pro - check their forum pls

and/or Lion...

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, though I'm not certain. There are two "classes" of failure. This is the first. The other is the long wake-up: the power button will not wake the computer, nor will spacebar/return/escape hit repeatedly, until it decides its ready. But there is another more puzzling failure: clamshell closed, CUP running, I lift the screen and the login window flashes long enough for me to type my first characters, then the screen goes dark. I close the clamshell and the CPU goes back on, the LED shines brightly, the screen goes dark (no glowing apple on top). I lift and repeat.

I solved this issue by noticing that the screen would light up as I was closing the clamshell. So now I close the screen to about 1 inch from full closure, and then pull it back up to see not the login window, but my desktop ready for work. It seems like display, CPU, and power management are all out of sync.

I have a similar problem since upgrading to Lion a week or two back.

I attempt to sleep the display. It goes black for 2 to 3 seconds. Sometimes 8 secs. Then turns back on again.

If I sleep the computer, it spontaneously wakes.

I thought it might be the camera noticing me move - or breathing - but I don't think so. I turned of Facetime, for example.

iMac 2.8 GHZ Intel Core i5, OSX 10.7.1

Activity monitor shows 'mdworker' operating at around 50 % CPU, on one core. That might because I am uploading a large file to Vimeo from iMovie. 4 hours to go, and I need to sleep the display, and put myself to sleep!

I'm also using an early 2008 Mac Pro and my issues are with waking rather than sleeping: as others have described, if I hit a key to wake the system up, the CPU comes awake, but the monitor stays off, and after five seconds or so the CPU goes back to sleep. If I hit a key a second time a few seconds after the first time, the system wakes up. Issue isn't related to any settings for screen saver or energy saver that I can establish.

An update.

I installed the latest Lion OS, 10.7.2. The issues still remain. ie: 'sleep' does not work permanently.

I will go and shut down my iPad and the AppleTV and see if that makes a difference to the result when I issue a SLEEP command.

I have: iMac mid 2010 2.8GHz intel Core i5, 16 Gb memory

I've had the identical problem -- black screen while waking and then computer will go right back to sleep (machine is 2 x 2.66 GHz Intel Xeon running 10.7.2). I've discovered if you click and move the mouse while the Mac Pro is waking, it works to wake the screen.

Mac Pro (mid-2010) 2.8 Quad Core Xeon. Lion 10.7.2

Samsung P2770 SynchMaster Monitor and have Lion set to prompt for password upon wake-up.. Machine went into screensaver (definitions scrolling across) and moving the magic mouse or hitting any keyboard button wouldn't bring it back to a password prompt for me to enter. Had to shut it down manually. Very odd. First time it happened too..
