Thanks, you guys are always very helpful. I will take your advice and keep an eye on things. I appreciate the input... ;)

Oh oh, it is better but sometimes it still doesn't wake up. Wish Apple solved the problem because this is really annoying! :(

Apple can't fix your problem if you don't bring it to their attention. You may have a sleep sensor problem. Take your laptop to an Apple service shop for some testing, or call AppleCare support.

hansfeil, what devices do you have connected to this computer? Please list everything, even things like USB hubs which might appear to be insignificant. In reality, anything that is plugged into the laptop might be important.

What devices have you installed drivers not included with OS X onto this computer for, whether or not they are currently plugged into it? Things like USB network devices, for example, or external sound cards, or any device driver that you installed since getting this computer might be important.

Can you show us your logs? You can easily view them yourself using the Console app, found in /Applications/Utilities. The system.log would be a good place to start, so please attach it to this thread as a .txt text file.

I have attaeched the powermanagement log if that helps.
But I followed http://tancredi.co.uk/2007/12/9/solv...om-sleep-issue and since yesterday I have no sleep-wakeup issue anymore. Could be just lucky.....

MacBook won't wake up after sleeping???
 

To all those having trouble waking MacBook up. I was you until yesterday. Finally found the answer, & mine works perfectly again. Hope this will help you:

Pull up Finder:
-Devices/Mac HD/Library/Preferences/System Config

Do you have a file called comapple.AutoWake.plist?
-If you do, this isn't your problem.
-If you don't:
-Pull up System Preferences/Energy Saver
-Make sure you are on Sleep tab, not Options
-Click on Schedule (bottom right corner)
-Check box for "Start up or wake"
-Click OK
-Now click on Schedule again, & uncheck
"Start up or wake" box
-Again, go back to the Finder path, & see if
the comapple.AutoWake.plist is shown.

If this was your problem, it should fix it; at least it certainly did mine. Don't ask me what happened to the original plist, can't tell you. If it doesn't fix it, sorry...!

This made it better for me for a while but the problem returned!!

hansfeil, could we see your system.log from when this happens? The powermanagement log you attached is difficult to parse, and I am having trouble getting anything useful from it.

Also, as mentioned in my previous post to this thread, you need to tell us about what you have connected to the computer.

Trevor

My system log
 

Trevor, here is my system log. A bit delayed but I don't get emails when a new post appears in this forum. Don't know why.

I hope this helps. System had several wake up problems on Oct.8

Regards, Hans

Dear Trevor,

Closed the lid of the computer at 00:44 and opened it at 08:10. Screen remains dark, "sleep light" went off and for the rest nothing except that I hear the HD.

Pushed the power switch for a few seconds, computer went OFF and pushed again to switch the computer ON.

I have attached the small log file. Do you find a clue?

Best regards,

Hans

hansfeil, I've asked twice for information about the peripherals attached to your computer. Will you please answer that question?

I note in the log from post #29, you have the following:
Hewlett Packard makes very good printer hardware, but their OS X drivers leave quite a bit to be desired. I would recommend completely removing the drivers that you installed for your HP, and seeing if that fixes your sleep issue.

Trevor

Hmmmm. This second log file is making me very suspicious about VMWare. I know that it's difficult, but could you experiment with removing VMWare from your system to see if that solves your sleep problem?

Trevor

Ok, I have uninstalled VMWare Fusion and restarted the computer, just in case. Let's see if it is getting better. One wake-up-from-sleep is not enough because sometimes it goes well for say half a day.

Hans

Occasionally I have connected an USB harddrive for Timemachine. But the problem doesn't seem to be correlated to the HD. The HP printer is a wireless printer connected via airport. HP software sucks anyway but I need a driver to print. Not?

I suggest, like trevor advised, that you remove the HP supplied drivers. Then, run the Install Additional Software installer from your OS X install DVD to install the HP drivers supplied by Apple. These drivers should work just as good, but avoid the additional background garage that HP tends to install. Afterward, be sure to remove your HP printer from the Printer/Fax preferences and add it again.

On 9/26, I sent a msg to check the AutoWake.plist in SysConfig. I'm sorry to say, that fix only kept my MacBook Pro going for a couple of days. HOWEVER...

I called Apple, expecting to have to pay a charge (no support agreement in force). The tech had me try a couple of things, & then confirmed the problem was due to an issue for which they are extending the warranty (three years). Mine is in under warranty repair now, & no charge for the phone call.

Turns out the NVidia graphics card, placed in certain models, is causing this issue. Apple is giving 3 options:
-Take yours to an authorized repair center, no charge,
-Send to Apple for repair (they sent me the shipping box
and authorization),
-Or, if you have had yours repaired & were charged for
it, they are issuing refunds.

Here's a link to the Apple Support page, explaining the issue:

http://support.apple.com/kb/TS2377?viewlocale=en_US

I have already received a Mail response from Apple's Repair Center. Mine is fixed, no charge, & on the way back. I hope this might help some of you having the same issues!

24hr with VMWare-Fusion uninstalled and no problems anymore. Keep my fingers crossed.

Hans

I read quickly through these post but
for info
I had steemouse (to control usb mice and keyboard)
and it did prevent a wake from sleep on my iMac; I had to force restart

since I Uninstalled steermouse, it is OK, I went back to Logitech Control Center(LCC) 3.0

That was too easy. After a while the problem returned. Two days ago I have removed HP IO and HP Trap Monitor from /library/startupitems. No clue what they do but I can still print and since the problem didn't occur anymore. Again, fingers crossed....

Hans

I believe that those two processes are related to scanning over the network.
