Problems going to sleep, waking up, restarting, etc

I just bought a refurbished Macbook...and we are already developing an intense love/hate relationship because of it's eratic sleep behaviors. So this morning I tested it by trying various methods of sleeping/waking/restarting.
Here are my morning Macbook activities:
1: Macbook is sleeping, I open it...it appears to be functioning...then 5 minutes later, I get the "you need to restart your computer" box (the one with all the different languages)
2: Restart--Freezes on blue screen with rotating wheel
3: Turn off/on using power button
3: Put to sleep using Option/Command/Eject; wake using power IT WORKS!!!
4: Put to sleep by closing lid; open to wake and it seems to work! I try to shut down using the Apple menu...and I get the spinning beachball...
5: Turn off/on using power button
6: Reset PRAM
7: Put to sleep using Option/Command/Eject; wake using power
IT WORKS!!!
8: Put to sleep by closing lid; open to wake...seems to work but the spinning wheel appears on the desktop and I have no mouse...so I have to restart it AGAIN
9: Put to sleep using Option/Command/Eject; open to wake;
IT WORKS!!!
10: Put to sleep using Option/Command/Eject; wake using power...seems to work but when I open my airport menu, it freezes and the menu becomes unaccessible and will not disappear...restart AGAIN
11: Put to sleep by closing lid; open to wake...so far, so good...
This basically covers every issue my Macbook has had in the last week, except for the three or four times it just won't start and sits on a black screen, going through some script indefinitely...yeah...that one didn't repeat today.
Yes, my software is up-to-date...
Yes, I reset my PRAM...
Yes, I reset the SMC...
Any suggestions would be much appreciated!

Hi -
I'd try booting to your Install DVD while holding 'D' ...this will launch the Apple Hardware Test.
If things are fine here, then start to that DVD again but this time hold down 'C'. When you finally have a 'top menu' bar across the screen, use it and launch Disc Utility and then verify and repair both permissions and the disc itself.
On restart, reset your SMC once again...

Problems going to sleep

Ever since the 10.4.6 upgrade my Mac is having sleep problems. It refuses to sleep when told to by system preferences like it used to. I can put it into sleep mode manually and it wakes up fine. I tried resetting something or another, as recommended by Apple, by holding down the power button as I plugged in the power lead but to no avail.
I have no other users on the system and can only only really put it down to 10.4.6 update. My machine is a G5 1gig Ram 2.0ghz 17 inch.
Any ideas.

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.6 Combo update. Others reading, download the combo update that applies to you!
Cheers!

Problems going to sleep after 10.5 upgrade and new memory

Looking around the forums I notice lots of problems with sleeping computers and Leopard. Here's my story.
After upgrading my eMac with new memory (now at 1 GB) and Leopard, I have problems getting it to go to sleep after logging out. What happens is at the logout/login screen I click the sleep button, it goes gray for seven or eight seconds or so, then goes active again and the computer stays awake. I have to click-and-wait three times before the computer will sleep. It is a consistent bug in that I always have to click three times.
I figure this is more likely a Leopard problem than a memory problem. I bought the RAM off eBay but they are name-brand chips and haven't given me any problem.
Any thoughts?

Andy,
I would pull out to the new RAM upgrade and see if your sleep issue is hardware related. If your Mac still doesn't sleep correctly, I would try reloading OS X from your retail discs, then upgrade to 10.5.2 making sure you use the Combo Updater instead of Software Update.

K8N Neo 2 Platinum Problem!When rising to 210fsb restarting,etc...

I have a big problem which makes me angry...Actually there exist some problems,but I only write two of them...Firstly,when i try to overclock as rising fsb to only 210, system restarts and resarts again and again;only when I return to default value,system works.It is just a one example to show us that mobo does not work well.Secondly,about the temperature,there is a problem.System sometimes opens with 37degree,sometimes with 43 degree;sometimes rises to 55 and 62,sometimes stops at 47-48.These are not only from idle temperature but also load.Which makes me angry,temperature is 55 degree at idle;and sometimes at load it is 49 etc..I tried my CPU and fan,ram modules etc.,on MSI Neo 4 SLI mobo,and there didnot happen any problem,involving these two.So,I think they are not normal,what should I do?
My system:AMD 64 939 3200+ CPU,MSI K8N Neo2 Platinum,MSI NX6800 VGA,2*512 ddr400 Hynix d43 ram,80GB Seagate SATA etc...

I did it;that is to say i know that i have to lower HT and i did.In detail,ram timings were 3-4-4-6 and 1T.I disabled D.O.T,Spread spectrum,Agrassive timings,high performance mode was manuel etc..So everything was suitable for o\c.Also I disabled Sata1-2,and connected to Sata 3 port.AGP frequency was 67,cool and quiet was disabled.HT was 4,I adjusted CPU ratio to *10 and I rised CPU frequency only to 210.So,everything was as which had to be,but system restarting again and again,works only if i return to 200 fsb...I am sure that the problem is arisng from mobo,because I tested my configuration on different systems.For example,I tried my CPU and ram modules on MSI K8N Neo 4 SLI mobo and there did not happen any problem,I was able to rich 2500mhz with HT4,250fsb*10.Temperature was accurate also.What can I do?If
I cannot o\c my system it is unsense to have this configuration and this mobo.I think,if i bring my mobo to service of MSI,they will say it is not our problem,as you know they don't accept o\c problems.I also think that they have to explain something to me as their D.O.T. technology supposed to work at %11 o\c.Please,someone say something to me and give me an advice.

Apple macbook pro 15" 2 months old won't start after going to sleep. have to restart whole computer

Firefox freezes up when my iMac goes to sleep, & I must restart it everytime. Is there a solution?

it just locks up. I'll leave then come back to a webpage and Firefox will be frozen. I have a new iMac, but it was the same way on my old iMac. Seems like there is an issue on how the browser interfaces with my apple computer. any solutions, so I don't have to switch to Safari?

That's your answer then. Return the keyboard, get your $$$ back & purchase another keyboard that is compatible w/your currently installed OS.
Always read the system requirements prior to making any purchases pertaining to a Mac & your currently installed OS.

My MAC mini looses the wi-fi connection to a Belkin N wireless router when it goes to sleep or shut down. I have to re select the network when restarting or waking the computer up. I think this just started with Lion. My iPod and iPad have no trouble.

Thank you BGreg. That is what I have been doing, and then it works just fine. I think it was doing the same thing in the previous version of Lion. I may be incorrect about that. I upgraded to 10.7.3 a few weeks ago, and then last week I reloaded the combo update, hoping it would help. Not so. Thank you for letting me know it is a common problem. I have tried permissions in Disk Utilities, and in Macaroni, both at least 4 times, plus numerous restarts. Nothing Improves. It still can not find the internet when it wakes up or gets up.

Since upgrading to Yosemite my computer closes down instead of going to sleep. When I restart I get a message saying your computer shut down because of a problem. Has anyone a similar problem? What is solution?

Since upgrading to Yosemite my computer (iMac late 2012 model) closes down instead of going to sleep. When I restart I get a message saying "your computer shut down because of a problem". Does anyone have similar problem? What is the solution?

Sorry, I was acting like it was an email. See below:

My new Mac Air continues to disconnect from WiFi after going to sleep. When waking it up I have to manually re-connect. How do I keep it connected?

My new Mac Air continues to disconnect from WiFi after going to sleep. When waking it up I have to manually re-connect. How do I keep it connected?

I had this problem too and solved it by doing a clean install. After that it was gone.
This is a drastic method since it takes quite some time to reinstall lion and all your software.
Thoughts I had why it started working after a clean install are the following:
It looked like the airport wasn't able to reconnect fast enough before the connection timed out. So what could have prevented my mac from being able to connect fast enough?
Apps that consume processor cycles. I love what I would call 'System Enhancers', little apps that enhance my workflow (Moom, Alfred, Dropbox, Default Folder etc). I'm not saying that these are the problem, they might be programmed processor friendly, but check if you have apps that consume processor cylcles. It might prevent airport from being able to reconnect quickly enough before it times out.
Mobile Config profiles. Another thought I had was that I had a mobile config 802.1X profile installed for the company were I worked. It used TTLS to connect to the corporate network. This profile might have gotten in the way.
And a sidenote...
Routers with hardware acceleration might also be a problem. My router is a Wireless Gigabit Router 300N WL-351 and has hardware acceleration. As soon as I activate that my wifi connection keeps dropping. It is as if a Macbook Air can't handle that amount of optimisation.
That's it, hope it helps those who are still having the problem.
Best, Jan

Now every time my computer goes into sleep it won't wake up.
The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
This only happened after reinstalling. Only Apple OS was on the imac and so it must be an issue with the software I believe.....
Anyone know how to cure this problem please?
Thanks

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.

HT3964 My MacBook Pro i5 Dual Core has a hardtime waking up when the computer is put to sleep and only when it goes to sleep and has been asleep for a while. The indicator light flashes on and off for a while and then freezes. I've done an SMC reset once.

Does any one have the same problem with their MacBook Pro i5 Intel Dual Core? If the computer goes to sleep (not the screen) and is asleep for a while, when I try to wake it up it doesn't respond. I have to power it downn and restart it and sometimes it takes two or three attempts. Otherwise it works fine. I upgraded the memory to 8 GB. That is the only alteration doen to it. I've performed one SMC restart and now it wakes up but it takes a while and a gray screen shows up. When I insert a DVD it won't start automatically I have to start the application in order to see it. Any suggestions?

My macbook pro goes to sleep by it does not wake up. I have to restart it. I had recently to change the board in the attached Thunderbolt display.

my macbook pro goes to sleep by it does not wake up afterwards. I have to restart it. I had recently to change the board in the attached Thunderbolt display, because I noticed that the same problem arose when the display was attached.
Now with the new board, it can't be the display's fault. I hope it is not macbook pro's main board fault. Maybe hasthe notebook board been damaged by the faulty display?
To bring my MacBook Pro to service will slow down my work. This is why I am posting this message, in the hope to be able to run a diagnostic test myself.
Thanks a lot, in advance.

Hello Aminetti,
It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
Reset NVRAM/PRAM
Test with external devices disconnected
Try Safe Mode
Try another user account
Thank you for using Apple Support Communities.
All the best,

PB 12" OSX keeps going to sleep - power problem?

My 12" 867MHz Powerbook has developed a fault that results in the screen going very dim and the PB going to sleep, even before it's displayed anything on screen.
Everything sounds good - I get a startup chime and the usual disk noises and sometimes I can very faintly see the desktop. I can wake it very briefly by pressiing the power button, but it nods straight off again.
Stranger still, it tends to work perfectly for a short while if it's been left off for a long time (like days or weeks). When the problem first developed I was able to remedy it by removing the (perfectly good) battery and running it straight off the adapter, but that doesn't work either now, and a new battery didn't help.
Anyone come across this before? I have a nasty feeling it'll be expensive!
I'm not actually sure which OS it's running as I can't see, but it is X.

There may be a number of things to try to establish the fault.
1. Go to the utilities, console and open this up press the logs button and take a look at the system logs, it should give you some idea of whats happening i.e power management recieved an emergency overtemp signal going to sleep...
or something like that.
2. run the Apple hardware diagnostics to see if it finds any faults with any of the hardware. This should be on a cd that came with the machine.
3. if its a thermal problem then do a search on google for temperature monitor OS X. Set the preferences to update every second. Get it running and take a look at the history if one of the sensors is acting wildly then it can be a bad sensor. (trackpad sensors seem to be a favorite to go wild)
4. Also do a seach for smartutility and have a look at what this says. If it says your hard drive is failing then get it replaced.
I had similar issues with a 1.67mhz powerbook, every diagnostic and test I ran found nothing yet it would sleep sometimes every few minutes. Even after reinstalling the sytem, resetting the pmu etc. All the disk utilities I ran told me the hard drive was fine, except smart utility. I cloned my sytem onto a replacement drive replaced the drive and its been fine ever since.
If it's a temp sensor then if you search around there are ways to disable them by removing bits of software. Or you can take it apart and physically remove them, but I woulnd't recommend it. Other wise you may need to take it to a store to be fixed.
Good luck

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Turn off Bluetooth and test.
8. Reinstall OS X.
