Since upgrading to Lion a few days ago, my iMac (2010) won't wake up with magic keypad swipe, button press, spacebar or any other key. Works fine and wakes fine when used periodically during the day, but is locked tight upon first use in the AM. The only thing that works is a hard power off and reboot. Any thoughts? Thanks!
iMac, Mac OS X (10.7)
I have the same issue.
Since installing Lion my iMac won't wake from sleep after an overnight sleep. I can get it to wake by pressing the power button, but then my wireless keyboard, magic mouse and trackpad are unresponsive.
Only a hard power off and reboot will make them work again.
Bluetooth keyboard?
Are you sure that in System Preferences/ Bluetooth/ Advanced the Bluetooth is set to wake up the computer?
For me, yes and yes. Bluetooth devices are allowed to wake up the computer.
Also, during the day there is no problem when waking up the computer when used periodically. The issue only occurs during an overnight sleep.
Perhaps Spotlight is cannibalizing the computer? Uncheck larger db's, like mail, images, music etc. to see if this helps.
Also: I had the same problem once in 10.6.6 and here it was solved by setting the "hibernatemode" to zero (then no sleepimg is made).
In Terminal:
sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage
The last line deletes the sleepimage which has the same size as your Ram memory.
I already checked my hibernate mode in terminal by doing:
Pmset -g | grep hibernatemode
It was already on hibernatemode 0. So that can't be it.
I now excluded larger db's from spotlight and see if it will have any effect.
I'll report back.
Thanks in advance.
Exactly my issue. I thought it was fixed by a router firmware upgrade when things worked OK, but the same thing happened later this AM. Had to do the cold boot to get things working again.
Yes, my bluetooth devices are all set to wake up the computer and they USUALLY do..just not always -- like mostly overnight. Only has been a problem since Lion update. And....only on my iMAC. My Air is working fine after the upgrade.
Just wanted to add to this thread that I am as well having the same issues as you with a 2010 iMac i7. No problems during the day but following overnight sleep, cannot re wake using any input device, thus needing a reset, which generates an error report on startup for submission to Apple.
I have tried and checked all of the above advice, to no avail. Are there any other known solutions or routes to explore?
Same issue here. iMac 27" 3GHz Core 2 Duo, wireless keyboard, magic trackpad and magic mouse.
I did a recovery installation of Lion to be sure that no Snow Leopard components are installed anymore but the problem still exists. Wake up from standby during day time no issue but it does not work after a longer period of time in standby. Only a hard power off/on helps.
With Snow Leopard it worked perfectly.
OK, kev. You probably already did the SMC reset.
Do you have a Wacom tablet connected? What is there in your Account/Login list?
Yes, exactly the same with me. The iMac worked previously before, but not after Lion. Its been a little consistent. Mostly an overnight problem but also lost connection during the day after a couple hours away a couple times. I also upgraded a Mac Air at the same time -- not a hint of any problems. Hopefully Apple will do something to fix this.
Yep, I did the SMC reset.
No, I have no Wacom Tablet or anything else connected. I even disconnected all of my USB-connections like my printer and external hard drives.
Do you mean what my login items are? The programs and stuff which startup every time I log in? I need to check it when I get home.
Just wanted to add to this. I posted somewhere else also. I am having the same problem as everyone else here. iMac 2009 sometimes won't wake from sleep since lion upgrade. Worked PERFECT in snow leopard. Only thing I wanted to add is, check out if you loose Internet connection. After the third time this happened, I started poking around (I have limited knowledge on a mac as a former PC tech 😝) but I noticed that my Internet connection was no longer working. I am using a wired connection (wifi is off) I have an IP address, but I am unable to ping anything. I also noticed that in the Bluetooth settings, the mac detects my Bluetooth magic mouse and keyboard, but they just don't respond. I had to plug in a USB mouse. can someone tell me the command to run in terminal to check if Bluetooth is running? I'm wondering if I can kill and restart the process maybe that would work??
A reboot of the machine seems to fix the issue as all is working. But it's very random. My imac went to sleep last night, wake fine this morning. Then later this afternoon after I came home, the issue happened again. Very weird.
I used to touch the Trackpad to wake the computer up but now i have to click it. At least it works.
Update....my iMac went to sleep today when I went to work. I was able to wake it from sleep with my mouse and keyboard, internet etc.....all is working fine. Go figure.
