Macbook pro runs hot when asleep

i have a macbook pro 2.26 intel core 2 duo
when i shut the macbook it goes to sleep, then when i go back to it an hour later, it is too hot to even touch.
the only open programs were ical and address book.
any help?

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
These are symptoms of a computer that does not actually go to sleep but continues to run.

Macbook Pro running hot when using iPhoto

Hi Folks,
I hope someone can help me with this...
Last night I was working on some pictures in iPhoto and noticed that my MacBook Pro was getting extremely hot and the fan was working overtime.
I then quit iPhoto and the fan started slowing down until finally 10 minutes later the MacBook Pro cooled down.
I also noticed that the whole system was slow and safari would load pages anymore or very slow...
I called customer support and we have done the following:
- reset Safari
- deleted cookies and cleared history
- reset SMC
- reset PRAM
- reinstalled Mountain Lion
The installation of the OS fixed my computer but this morning when I continued to work on my pictures again it started doing the same thing.
I opened up Activity Monitor and saw that iPhoto uses >400% CPU and sometimes even more!
Now my whole system is very sluggish again and doesnt respond for minutes at the time...
What is the problem here?
Any help is appreciated.
Thanks.

MacBook Pro running hot when watching streaming video

... But not on all browsers!
Hi all,
It's me again. I hope I'll have more luck with this new topic than with the one I posted earlier about my MacBook Pro shutting down because it was (I think) overheating.
(see here: http://discussions.apple.com/thread.jspa?threadID=2221808&tstart=0 )
Anyway, I think we're along the same lines here: I visited YouTube and launched an NBA-related video on Opera (my default browser) and Firefox, and both caused instantly my Mac to overheat again (up to 90°C on Firefox), but when I tried the same trick with Safari, I noticed nary a rise in temperature!
My question is simple: how come...? Better integration and plug-ins? Better caching? Some other thing?

At a guess they are using different Plug-Ins to play the video.

Hello, I have a problem, my macbook pro runs slowly when unplugged but if I plugged it, it runs perfectly.

The battery needs to be replaced, or there is some other hardware problem.

Safari 6 makes macbook pro run hot.

Hello, this is my first post in this forum.
I've noticed that often Safari makes macbook pro run hot. The fans speed up even though I don't have that many applications open and only a few Safari tabs open.
The only way to slow down the fan is to quit safari and open it. Did anyone else also notice this?
Also I have noticed that Safari doesn't display texts (especially in facebook chat) properly.

Try trashing the Safari cache more often ...
From the Safari menu bar click Safari > Reset Safari
Select Clear History (also empties the cache)
Deselect the remaining boxes then click Reset.
Quit and relaunch Safari to test.
If that doesn't help, check Safari > Preferences > Extensions
If there are any installed, turn that OFF, quit and relaunch Safari to test again.
Emptying the cache and deleting history may also help the Facebook text issue.

Macbook pro runs hot

My early 2008 MacBook Pro runs very hot and can't tell if the fan is running.
Any suggestions?

User Tip: How to deal with MacBook Pro and MacBook heat?

15" MacBook Pro runs hot, fan is loud, and incredibly low battery life

My 15" MBP was bought in March or April (can't remember) from Singapore Apple Store. Here are the stats:
MacBook Pro 15-Inch, Late 2011
Memory 8 GB 12222 MHz DDR3
Software Mac OS X Lion 10.7.5 (11G63)
Also I'm using about 1/2 of the available 750 GB of storage.
Here's what's up:
1. The fans boot immediately after the computer is turned on and never stop, making everything much too loud...like a plane is taking off or something.
2. The computer is WAY too hot. Right now I'm running Astrill, Chrome, Activity Monitor, and System Utility, and when I put my hands on the thing it feels like my fingers are going to melt.
3. The battery life, even at a full charge, is about an hour overall, which ***** for so, so many reasons.
Here's what I've tried:
1. I took it to the Shanghai Genius Bar, but I think that the language barrier is impeding my ability to really say what's wrong. I backed up, and they wiped the hard drive, re-loaded the OS and put all my old stuff back on the computer. They also deleted SOMETHING from the Preferences part of the library, but I don't know what it was. Everything runs much faster now, but the fan, the heat, and the battery are still having their issues.
2. I've checked the "all processes" CPU usage. There's nothing unusual (as far as I can tell), so I'm at a serious loss as to say why the computer is running so hard. Even with all the processing running as you see below, the fan's still blasting and I've lost 50% battery life in the past 40 minutes.
3. I've tried the fix that requires deleting com.apple.desktop.plist and com.apple.desktop.plist.lockfile. It changed the way the desktop looked and absolutely nothing else.
PLEASE, PLEASE, PLEASE help me! I'm a graphic designer and often run the CS6 Suite. (Currently, however, I am NOT running any Adobe programs and I'm still experiencing the problems.) It's really important that I am able to run Photoshop, Illustrator, and InDesign at once, and it CAN, but with the heat problems I'm having without ANY of the graphics stuff running, it worries me.

Just took another look at iStat Menus (I've only had it for a couple of days - I used to use the old iStat Pro widget) and it seems as if you can make fan speed defaults and use them instead of relying on your MBPs sensors to take care of the fans... see...
Might want to use that 'medium' speed (there by default as I know I didn't add it) and keep an eye on your temps. If you start heating up to much, go back to the 'Default'.

My MacBook Pro gets hot when I'm not doing much and when I watch YouTube videos the video skips, scrolling doe as well.

I bought the new, and my first MacBook Pro 13" a little over a month ago for college and love it, but have started to realize a couple problems I can't seem to solve. The bottom of the MacBook becomes very very hot in a short amount of time, and I really don't think I'm doing much to cause it. Another issue is while I watch a Youtube video in HD, even if it's completely loaded, it skips every so often and is slow and also makes my computer very hot. When I try to scroll up and down to view a web site, it also sometimes skips. I really never thought this would happen to Apple computers and hope someone can help me fix these problems! Thank you very much in advanced!

The widget that works well on your Dashboard is called IStat Pro, It monitores all running statistics updated every 15 seconds. Your fan always runs at about 2000 RPM and will increase up to 6000 RPM after 140 degreesF and higher is reached. This widget will show you continuos measurements for you to see

My MacBook Pro runs HOT!

I have a first gen MacBook Pro. 2.16 GHz with 2 GB of RAM. I have noticed out of all the MacBook Pros I get at work, mine runs the hottest. I use SMC Fan Control to give me my temps. Mine with iTunes, Entourage, FireFox, and Adium running at default fan speed of 2000 RPM, my temps get to 163-167 F. I tested another non Core 2 Duo with the same specs as mine, and same programs. It not only ran cooler, but 20-30 degrees cooler at the default fan speed. A few of my co-workers who had early MBPs say that their temps normally averaged 100-120 F at the default speed, but they would bump it up to 3000-4000 to get it cooler. I had to run my fan at 6000 RPM to even get it to be nearly as cool as these other MacBook Pros at my work. I am definitely not to happy running the fan at 6000 RPM to get it even bearable on my lap. I know that the first gen MBPs run hot, but god 30 degrees hotter? What can I do about this?

They run hotter and work fine. Installing haxies that disable a CPU sounds totally daft and I certainly would not buy a dual core computer then use one core.
There are a number of cooling pads with fans that add additional cooling and protect the motherlode when using on your lap.

Macbook Pro shuts down when asleep overnight

Specs: Macbook Pro 9,1, 2.6 Ghz I7, 8GB Ram, running 10.8.2. No other problems that I'm aware of. This started a couple of weeks ago:
Behavior: When putting my Macbook Pro to sleep overnight, it shuts down several hours into the sleep process. A press of the return key restarts the computer. This behavior is not desired. I want the computer to sleep overnight, not shut down. The computer is not on a schedule to shut down or restart.
Other programs running: Dropbox, Google Drive, Fantastical, TotalFinder, Chrome
Overview of console system.log from this morning: Log begins at 12:36 am this morning while the computer is asleep. It wakes up at 4:36 am and these are the last processes before being booted at 10:41 am.

MacBook Pro running hot after upgrade

Hey everyone,
First off: Upgraded to Mountain Lion and I absolutely love it. I'm running on a December 2011 MacBook Pro Unibody 15", 8 Gigs ram, i7, SSD 256 drive (Apple). It had Lion installed when it came, obviously.
Now that I upgraded to Mountain Lion, it's running several degrees celcius hotter than before, after a couple of hours of using it. I figured I'd give it a few hours to do its search database thing etc...you know, let the system stuff in the background settle down, but it's still running very hot.
Is this something which eveyrone else has been experiencing? I've got two methods of checking the tempurature: iStat Nano on the Dashboard (which I don't use for anything else...) and smcFanControl which sits in my menu bar. Both give me the same tempurature and it's running literally about 5 to 7 degrees more (or sometimes even spiking at 15 degrees more for a few seconds) than before.
Just wondering if I'm the only one? Should I be patient and give it a day or so? Any tips?
Thanks,
Nat.

You're right that in the first few hours ML will be busy in the background running certain processes like indexing Spotlight and Time Machine.
You can see if these are still indexing by looking at the menu bar. Click on Spotlight - if you get a progress bar saying its indexing, just leave everthing alone till its finished. If you look at the TM icon, it should be slowly circling if TM is still indexing. Again, click on the icon and see what it says.
If these seem to have completed, check in Activity Monitor.app (Applications/Utilities/Activity Monitor.app) as to what is using up %CPU time. If you see kernel_task is running wild (+80%) , try a PRAM reset. To do so, folllow this procedure:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
‘command’ – ‘option’ – ‘P’ – ‘R’
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should and with the kernel_task process back to normal.

MacBook Pro running hot after Mt. Lion upgrade

MacBook Pro mid-2009 2.53 with 8GB RAM and 750GB 7200 rpm harddrive: CPU seems to be running much hotter (>70 degrees C) and fan is the normal 2000 rpm per iStat after upgrading to Mt. Lion 10.8.1 and 10.8.2. Bottom of laptop near center screen side is the hottest area. Any ideas why? Or how to cool it off again to the way it was before the upgrade from Lion?
Thanks.

Thanks for your links. My MacBook fan was running constantly from switch on and the underside was getting very hot. Using your first link, I followed the Activity Monitor instructions and found that Dashboard was using '117%'. As soon as I closed it down the fan instantly slowed and after only a few seconds switched off..
Thanks again..

15 inch Retina macbook pro running hot/overheating.. what to do?

Hello,
I just got my new retina macbook pro. FIrst impressing- the thing is awesome. However, In the process of putting all the stuff from my old PC onto this new machine, I was importing photos into iPhoto. I noticed the computer getting very hot after importing about 1000/5000 photos, so cancelled the import. I downloaded temperature guage from the app store, as well as iStat Pro. Below is a screenshot taken with both monitoring apps open while attempting the import. (these were the only three programs running at the time).
This is a little unsettling.. a 3800$ computer that 'overheats' while attemping to import photos...? Is this normal? I called apple and they said to bring it into a store and the tecs will have a look. I asked if i could simply return the computer (as it hasnt been 14 days yet), but i was told i would be charged a 10% (or roughly 380$) restocking fee...

I note that the CPU temperature shown by iStat pro and Temperature gauge vary significantly. What the former reports is satisfactory but not the latter. Both cannot be right. I have used iStat pro and Temperature Monitor and they are always very close to each others data. You might download same and see how it compares with the other two temperature monitors:
http://www.bresink.com/osx/TemperatureMonitor.html
For a little peace of mind a trip to the Apple store genius bar would be a good idea. At least it will tell you if the 'Temperature Guage application is accurate or not.
Ciao.

Anyone have macbook pro running hot?

I have a early 2009 Macbook Pro that appears to run extremely HOT, unless I unplug the power block.
Any one have this problem? Im thinking its the power block?

While it is charging and very hot do the following.
Open the Terminal app - it is in your Mac's Utilities folder and looks like this
Select the entire line that follows (triple-click to select it), select Edit > Copy, and then Paste it into the Terminal window:
pmset -g sysload;pmset -g batt
Drag your cursor from the point at which you pasted that command all the way to the end, and copy the text. Paste it in a reply.
