Sleep and to hot to touch problem

I'm reading all these problems about the MBP getting to hot to touch while sleeping (not).
I haven't seen anybody put all there specs down. I think it is a graphics card driver problem but can't be sure because not everyone has said if they're using "Better battery life" or "Higher Performance".
We never have this problem with our two new MBP's unless we are using "Higher Performance" If we remember to change to "Better battery life" our MBP's never get too hot to touch. However, the few times we've forgotten to switch and left them on "Higher Performance" they've gotten too hot to touch while sleeping. I say sleeping but not really, as they never really go to sleep in this mode.
One of our MBP's is a 2.8 the other is a 2.53.

sounds like you have a hardware problem I would take it into a apple store

My 24"intel Imac Keeps going to sleep -it is hot to touch in the top left corner of the case -is something about to fail .

My IMac works for 30 mins without a glitch then starts putting itself to sleep every five minutes after that - it is getting hot in the top left hand corner - my guess is that something is on its way out - anyone had a similar issue before .

Why my mac book air warms up more and more often, more and more hot

Why my mac book air warms up more and more often,and more and more hot

I have this problem too when I use heavy applications like big intense games. When you use this, a lot of memory and CPU space is taken up. This causes the fan to spaz out. The fan tries to cool it off, which in turn makes an awkward loud noise. If it makes noise/and/or gets loud, go to "Activity Moniter" and see if anything is taking up a large amount of CPU %. If anything is 30%-70%, that a lot. Earlier, I transfered 2,400 pictures from my iPod to my Air, and it went crazy. Within like 3 minutes of it transferring, it got hot. I looked at the CPU %, and it was anywhere from 80%-somehow like 230%. Anything like games or apps or a lot of internet browsers can warm it up. One other huge thing that can cause this is airflow. If you operate it on like a pillow or something soft and/or somewhere with low airflow/circulation, your computer will get hot. So, either use it in your lap or on something like a table, and try not to overwork the computer. If neither of these things help, bring it in to the Apple store. I hope this helped! Good luck!

10.5.2 wake/sleep and closed-lid problems

As of 10.5.2 my MBP no longer works correctly in closed lid mode using a hardware
setup that previously worked flawlessly. After plugging in power and video, plugging
in the USB keyboard seems to wake the system, but no video. I then must open the
lid, unplug the USB and video and try to get the system to respond. I often must cycle
the power to reset the system--very disturbing to do that.
Also as of 10.5.2, I have had to power-cycle the machine when it has refused to wake
in open-lid mode and this weekend I the entire machine froze (no mouse movement,
no expose, etc) in the middle of work using a graphics-intensive program and I had
to reboot by cycling the power.
A friend also reported similar issue in which the system would not respond after the
screensaver became active.
Are others seeing problems like these? I am beginning to suspect that the post-10.5.2
graphics update has problems.

I just wiped my HD and reinstalled everything besides the Graphics Update. I can now close the lid of my MBP and use my external monitor alone. The Graphics Update had made that impossible.
Further, I am in the habit of putting my MCP to sleep and putting it in a backpack in the morning, meeting friends for breakfast, and re-awakening it at the office. When I did get to my office, I found (as another user had on another thread) that the MBP, even closed, had woken itself up and was hot as heck. I am uncertain that sleep will work properly under 10.5.2, but I know that the display wackiness of the Graphics Update was driving me nuts. I will not install it until Apple fixes it.
I looked around for awhile for a way to uninstall the Graphics Update, but could not find it...I suspect it exists somewhere.
The 10.5.2 Combo update (343MB download) DOES NOT include the Graphics Update, and at this time, I seem quite ok with everything else updated.

MacBook not going to sleep and getting very hot

I just purchased a MacBook and have been using it for a few days. I have noticed that it does not appear to go to sleep correctly and gets very hot in the process. I finished working on my MB about 45 minutes ago. At the time it was connected to the mains and I disconnected to catch my next train. I shut the lid and after a few minutes the sleep indicator light at the front dimmed once then stayed on permanently. I could not hear the drive spinning (though the drive is quiet on this machine and there was a lot of background noise) and assumed all was OK. Anyhow, I have just taken the MB out of its case some 45 minutes later and it felt extremely hot (almost too hot to touch, I would guess around 50ºC). The sleep indicator light on the front was solid white. I opened the lid and the machine woke up. Something not right here....Also power remaining was down to 72% so something has been using up a lot of energy and heating up the aluminium!
Tony
ps. Whilst writing this email the MB has cooled down considerably but still warm.
ps2. Probably not related, but I have firmware password protection enabled
null

I did see some of the other posts, but nothing about the MB getting so hot.
I tried sleep from the menu and this seems to work (though I have rebooted the machine since the above report).
What worries me is the potential fire risk/damage to the MB, the case was extremely hot.

Unable to connect to canon MG5350 printer wirelessly and also noticed running very hot to touch and a little slow at times. Can anyone advise?

I have been having trouble connecting to my wireless printer and removed printer from system preferences thinking I could reinstall easily enough, however my computer does not recognise/identify my printer when I try to add a new printer.
I then noticed that my Mac was running really hot to touch and is sometimes slow, is this a serious problem, i no long have technical support or service cover. Any recommendation as to what type of places I should go to get it serviced? Apple only?

For resetting or setting up your printing system, go to > OS X Mavericks: Reset the printing system

Sleep and volume buttons broken, but there's another problem.

The sleep and volume buttons on my Ipod touch stopped working recently, and on top of that, my speaker randomly cuts out.
If I squeese the top and bottom of my Ipod hard enough, I can get the sleep button to work for about 3 seconds.
The volume buttons have not responded to anything.
My speaker started cutting out on the first day I got it, but I thought it was because I had set it up wrong. Squeesing the corner where the speaker is located will make it work again, but only for a short amount of time.
I plan on taking my Ipod to an Apple store to have it serviced, but there is one problem.
I accidently cracked my Ipod's screen. The buttons stopped working MONTHS after it happened, and the speaker was already broken.
My Ipod is still under Apple's 1 year warenty, so would they fix the buttons for free under the warenty even if the screen was cracked?
I don't care about the screen getting fixed, I just want the buttons to work again.

I know the screen will not be covered, and I don't need it to be fixed.
What I want to know is will they fix the buttons?
I don't think the buttons would have broken because of the screen because the buttons broke 4 months after the screen broke.
And the speaker was broken right out of the box.

Battery Life is short and when i do charge the power supply gets to hot to touch?

Hi! I'm not sure whats Wrong with my MacBook Pro 15" - Mid 2010, i7, 4gb RAM, 512mb Graphics.
When i charge my MB it has a really short life (50 - 60 min) without using high demanding programs. I've had a look in system information and i found this; Full Charge Capacity (mAh): 4858
im not sure what it should be but does it sound like a healthy battery?
My second question, the power supply is hot to touch is this a contributing factor? I took it in to apple and they suggested to buy a new charger, so £65 later and i still have the overheating of the power supply and the short battery life problems, HELP!

That is not a good sign. Check the connection on the MBP to see if there is any foreign matter or discoloration evident.
Open System Information>Power and post this from your MBP:
(make certain that the charger is attached)
Also run an Apple Hardware Test. You may use the appropriate original install disk for this which has the AHT instructions printed on it.

IPod Touch had white screen and was hot

Yesterday my iPod Touch had a white screen and was hot. I tried holding the power button and home button and it didn't work. What happened was the iPod was off. I turned it on and saw it had 30% battery and then turned off wifi. I had it on a table, and came back 10 minutes and saw it was black and wouldn't turn on. I then tried to charge it and the screen became white and was really hot in the back especially. I think it was white for like an hour. I held the iPod in front of the AC to cool it down..... ..... It cooled it down and then the iPod went black ever since today. I can't seem to do anything to it...:/ My computer & iTunes do not recognize the device.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. Because of the hotness I suspect a hardware problem

I used the wrong password for my belkin wifi. Now that I know the correct password I can not get pass the unable to connect or join message. I have turned off all the options such as wifi and join and also put my touch to sleep.. but nothing seems to work

I used the wrong password to join my new belkin wifi. Now that I have the correct password, I can not get the to the join screen with the space to type in the password. I continue to get the unable to join message. I have put the touch to sleep and I have turned on and off the wifi and join options on the Network screen page. Does anyone know how to get pass this block of the wrong password to a new page that will allow me to type in the correct password. I see there is a option that asks if I want to reset the network settings.. is that what I should do? and what does it erase when I do that? Thanks for any input anyone has.

Yes. Reset network settings. Head to Settings -> General -> Reset and tap Reset Network Settings.

Mid 2010 Macbook Pro sleep and external display problem

I recently upgraded to the new 2010 15 inch core i7 Macbook Pro. The problem i have is that it will not detect an external display (23inch Cinema) after waking from sleep. This happens after using the display to extend the desktop and also when using the Macbook in closed mode.
I've managed to get it to detect the display only after either restarting the Macbook completely or by going into energy saver and switching to dedicated graphics then going back to detect display.
It seems that when on integrated graphics it doesn't register that an external display is connected. If i leave a program open and running that causes the dedicated graphics to kick in then it works ok. If i close all programs, shut the macbook pros lid, computer sleeps and external display shuts off. If i click the mouse to wake with lid closed, apple logo lights, machine starts up few seconds later macbook returns to sleep. If i open the screen the machine wakes as normal but the external monitor doesn't.
Any help is much appreciated as its starting to frustrate me now...
Many thanks
oh and im running OSX 10.6.3

I thought it was intermittent to begin with until i started looking into it. By leaving programs open, like aperture, before i put the machine to sleep it appears to wake the external monitor up without a problem. If i shut all programs or leave basic things open like safari and mail which don't require the dedicated graphics, then upon wake it wont register an external screen is connected.
Manually detecting displays in settings doesn't work.
Disconnecting and reconnecting mini display port doesn't work.
Turning off power to cinema display and powering back up doesn't work.
To get the display going again its either 1) turn off macbook pro and re-boot or 2) re-start the machine then the display is automatically recognised. Or 3) launch a programme that kicks in dedicated graphics then manually go in and detect displays again..... like magic the display then springs to life.
No ideas anyone??

iMac Sleep Problem Waking - Screen Black & Pixelization
Have a new BTO 27" iMac I received a couple of weeks ago. Of course it is running Lion 10.7....
I am having a screen problem "waking" my iMac. (I also have this problem randomly on my MB Air - mid 2011 model)
After the iMac is in true sleep mode
(I have it set to enter a password after sleep mode)
Screen is blank/off
I "wiggle" my mouse or trackpad
Screen is still blank (sometimes it may display my screen saver, but the screensaver is frozen)
If I start moving the mouse or trackpad, it starts "un painting" the black screen. You can see whatever is supposed to be on the screen, such as the logon "button".
It is really wierd. Like a black "overlay" is painted on the resume from sleep screen. As I move my mouse or trackpad, it is basically erasing the black, to show what is underneath. Each movement of the mouse, erases a small black square.
I usually move my mouse around the middle of the screen to uncover the logon button. Press the logon button. The screen magically reappears as normal. I enter my password and system logs back on normally.
It only seems to be when the iMac is in really deep sleep mode. If the screen is just blank for an hour or so. I move the mouse/trackpad, and the logon screen is immediately displayed normally.
Any thoughts or recommendations?
Thanks to all in advance.
Greg

Still experimenting.
If certain programs are running (ie Firefox), then I don't have a problem coming out of deep sleep. It gives me a message when I reenter my password, that Firefox prevented the system from logging off.
Does that additional information help? It is a really annoying problem. And since I have it on my MBA, I am concerned it is more widespread. Does anyone else have this issue?

Black Screen and "Erasure" with Mouse.
I am having this same problem. I am using the Mac OS X Lion 10.7.2, not using a screen saver, and it happens sporadically upon trying to wake my iMac from sleep mode. The screen is black, and as you move the mouse over the screen, it "erases" the black, like the opposite of a blackboard, to reveal the login name and picture underneath. After that everything works fine. There is no pattern to this that I can discern (e.g. - happens every fifth time, only happens when a program isn't running etc.). It appears random, but is uber annoying, and behaves like a virus. I have Norton Antivirus, and it updates daily, and upon scanning states no virus is found. I also do system scan with MacKeeper, and it scans, says system is excellent. Something is definitely going on, I just wish I knew what it was. If anyone has any knowledge of this, any solution or insight would be greatly appreciated! Thanks!

That's because there are no Mac OS X viruses. You should uninstall Norton. You don't need 3rd party antivirus apps to protect your Mac from malware. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.

You don't need MacKeeper, either. You really don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space. It will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space.
Mac OS X does a good job of taking care of itself, without the need for 3rd party software.
Your problem, and the OP's is a graphics problem, likely having to do with the screensaver, not a malware problem.

Norton Antivirus, and what does it mean?
I suppose one reason I developed a concern that there was more here than meets the proverbial eye, so to speak was a message that I have received through Norton on multiple occasions. The last message of similar stated messages reads as follows (Norton Antivirus 2.2.1 (5) ): "Vulnerability blocked, December 13th, 2011, 8:57 P.M. When I click on "View Recent Activities", a window is opened that is titled "Activity Log." There, four columns are listed, titled from left to right "Date", "Event Type", "Result", and "Details." Under the December 13th episode, It lists "Portscan" under Event type, "Result" gives an IP Address (192.168.x.xxx), and "Incoming" under details.
I am admittedly a neophyte in the Mac world, having switched over from Windows 7 to Mac recently, but am intent on educating myself to the not-so-subtle differences. The above information that Norton displayed would lead one to believe that their antivirus software is protecting my iMac, and that its subsequent removal would have perhaps disastrous results ( i.e. - my iMac would be susceptible to said "Vulnerability", whatever it is, and that "Incoming would NOT be blocked). I had a conversation with Norton because previously, every time the stated "Vulnerability" attempted access, I was interrupted by a pop-up screen informing me of this. The Norton representative was able to turn off the pop-up screen notification, but stated that it would continue to log episodes of the "Vulnerability" when it attempted to portscan and access. So am I to understand that uninstalling Norton would leave my computer no less vulnerable to this vulnerability? It is confusing to me.
Furthermore, I suppose I did wonder if this vulnerability threat had anything to do with the issue of the black screen erasure with the mouse. I will attempt to post a picture of the screen as it was being erased with the mouse, and perhaps a short movie as well. As previously stated, I do not have a screen saver enabled. Thank you for your input, any information is helpful to me! _

Ditto & FYI Workaround
UncHeel...
Thanks for posting the picture. It is same as my iMac problem. On my iMac, it happens 100% of the time. On my MBA, it happens randomly like yours.
I began to notice if certain programs were running, when it went into screen saver and sleep mode, this didn't happen. And when I woke it up, I got a message that said "could not be logged off due to Firefox or Sketchbook Pro, etc. So that got me to thinking. So....
Over the weekend, I disabled "logoff after xx minutes of activity" in system preferences. That seems to fix the issue. I still have it set to require a password after the screen saver/sleep mode kicks it. But I disabled the logoff toggle.
Still not sure what this is an issue, but seems to be a work around. I just want to make sure my iMac is still going into sleep with these new settings. Including the monitor sleep.
Any thoughts based on this new information?
Thanks again

You have to remember that many antivirus apps consider cookies to be a "vulnerability" or "threat", when they're not. The only malware in the wild that can affect Mac OS X requires the user to actively install it. As long as a user is reasonably careful about where they get software, there is no need for 3rd party antivirus apps to protect Mac OS X from malware. Just make sure your firewall is enabled (System Preferences > Security > Firewall), and disable Java in your browser (Safari > Preferences > Security > Enable Java (uncheck))

You can let it sleep without logging off. That way, your apps/documents are still open when you wake it up, rather than having to relaunch apps and reopen documents. Recovery from sleep is much faster than from logging off.

I have had the same problem on my mid-2010 iMac since upgrading to Lion and it's been driving me nuts. The relation to automatic Logoff makes sense to me now that I look at my settings. The logoff was occurring after sleep and it's the only thing I haven't tried yet. I had previously thought it was related to Sleep but it never occurs if I force it to sleep. It only occurs after the system was left unattended and went through it's normal steps of screensaver then sleep. I'll try disabling the automatic Logoff and see if it fixes the problem for me too.

I can only declare partial success with unpicking "logoff after xx". It solved the pixelated screen issue but now the computer is not sleeping. I guess I'll have to uncheck file sharing now.

Still having the same issue here as well.
Have any of you tried a clean install of OSX?
Before I try a full reinstall I did an install on a external drive with no aps, just the bare install and I could not replicate the issue.
I continue to question if this is a graphics card firmware issue or and OS issue.
A reinstall (overlay) of the OS did not resolve the issue.
I have screen shots as follows:
1) Paint pixels on screen

Having the same issue
I have four MacBooks and a MacBook Air. I am seeing this issue on two MacBooks both running Lion 10.7.3. One is a newer i5 MacBook the other is an early 2010. The only common denominator I can think of is they are both set up with Parental Controls and they are set to logoff after X amount of time. The other MacBooks don't have this "pixel painting to revel the login screen issue" I also don't see it on our iMacs or the MacMini. Only the two with the issue are set to auto logoff. So the above poster is most likely on to something. I will give it a try by turning off the auto logoff on the two MacBooks in question. If that solves the problem then I will assume its a bug that needs to be addressed.

wchp - Thank you for following up and posting the screenshots. They match exactly what I was experiencing (and what UNCHeelYeah reported previously). I can confirm that I experienced the issue even following a clean reinstall of Snow Leopard on my MacBook Air (13-inch, Mid 2011).

Good thinking! Thanks for taking the time to test with your machines. This will help provide further validation of what gswilder (OP) tried as well in reply #6. Interesting about Parental Controls, too.
Side note:
Since I recently joined the Apple Developers program, I did a clean install of SL on my MBA then upgraded via the App Store to Mountain Lion to "kick-the-tires" if you will. Interestingly, I've not yet experienced any issue related to waking from sleep with a black screen and pixilation, even while running all the same apps I had previously. I'll report here (and file a bug report with Apple) if I do see this issue pop-up in ML. I'll be reinstalling SL in a few weeks and will report back if/when the black screen and pixelation issue reappears. I'll be sure to note the applications left running at the time the computer went to sleep.

I have experienced the same issue with my brand new MBA Late 2011.
I recently found out that this only happens when DISPLAY is set to go to sleep minutes before the "Log out after X minutes of inactivity". I had "Display sleep" option set to 5 minutes and "Log out after 10 minutes of inactivity" and this causes the display to go to sleep first (screen goes black) and then, 5 minutes later, it logs out.
If "Display sleep" is off and "Log out after X minutes of inactivity" is on, the issue does not replicate. So Im thinking it has something to do with the screen being black at the moment it logs out. Can you try and replicate that?
Thanks

Just tested this premise and yes, you are correct.
IF: Screen saver ON after 5m AND require password immediately AND Sleep (Display) after 30m AND Logout after 60m I am able to reproduce the problem.
IF: Screen Saver ON after 5m AND require password immediately AND Sleep (Display) after 30m AND Logut after xx NOT enabled, problem goes away
IF: Screen Saver ON after 5m AND require password immediately AND Sleep (Display) OFF AND Logut after 60M enabled, problem goes away
So on my machine (iMac 27, 3.4/i7, 16GB/1333, Radeon 6970m/2048MB, OSX 10.7.3
It would appear that if I am running Monitor Sleep and it kicks in prior to LogOff then I am able to reproduce this artifact. Only Display sleep with immediate login OR Loguot should be used but not both.
The only other thing to test is is I leave display sleep on, and screen saver on but with NO immediate password and enable logoff if the problem goes away.
Testing for another day.
I have linked this entire thread to a Apple support ticket and will report back on Apples response

Thank you so much wchp, this is brilliant. I have had this annoying problem for a long time. I eventually rang Mac support, they did not know how to fix the problem as you have suggested so they instigated many hardware replacements which eventually left my iMac severely crippled. They eventually replaced it with the latest model. But I spent two months working with a disabled computer which really interfere with my work.
Your solution appears to have solved my problem, at least so far, but I am hopeful that it is a permanent fix. I hope that your suggestions are taken up by Apple support. This may solve many users problems and avoid Apple making expensive fixes that don't actually work.
I thought that the new iMac would not have the 'Wake up from sleep by painting in the login window' problem but it did, this really annoyed me. Anyway now the problem appears to be solved, it's not I will repost and keep working on it. Thanks again.

If they are iTunes purchased music then go to Settings>iTunes and App Store and turn off Show All.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync/delete all music and resync
To delete all music go to Settings>General>Usage>Storage>Music>Tap edit in upper right and then tap the minus sign by All Music
