Macbook heat up issue

Hi,
I have a Macbook (Early 2008), I've been using it for a while with no problems at all. I'm running Lion (10.7.5) and everything was going smooth until this recent issue started to annoy me so bad, that I can hardly use it now.
Previously, whenever I'd watch an online video, the temperature would go up to 80° Celsius. If it were a long video, the temperature would hit 86° Celsius and the laptop would go to sleep mode. That was fine, it made sense to me that it needed cooling and since its an old machine, can't expect more from it, anyways it would wake up and resume activity as I pressed any button on the keyboard. On average use (web browsing, running apps and etc), the temperature remained between 60° to 65° Celsius. Since last night, the laptop constantly heats up even if left idle. The temperature is fluctuating between 73° to 80° Celsius. I tried playing a YouTube video and the temperature went up to 90° Celsius, the laptop went to sleep mode, but the fans kept spinning at full speed endlessly. I pressed spacebar but it didn't wake up, tried other buttons and the power button too, but doesn't work at all. Normally when in sleep mode, the sleep mode indicator light would be pulsing, but now I see its just lit, no pulse. I had to put unplug the power cable and even remove the battery to shut it off and then start it again. Same thing happens over and over again.
When I restart the laptop, a dialog box appears saying "You computer restarted because of a problem." and displays some crash report.
Can anybody help me fix this issue?

Thanks for the quick response Mike! I hope this is the info you've asked.

Fixing the macbook heat issue

Hi,
There is a fairly simple solution, to at least reduce the risk of damaging your macbook by letting it run at high temps. I bought my 2.0GHz macbook over the weekend, it was idling around 70 - 75 C. Thats a little high in my book.
I put the macbook on the vantec lap2cool laptop cooler that I have for my AMD64 HP laptop. Within about 30 minutes of running, the macbook was running between 42 C (idle) and 60 C (being taxed). Now the vantec is pretty cool, but its a little bulky for the little macbook.
I picked up a targus cooler for about $24 at the local walmart, its keeping it idle around 48 C, and under normal conditions (text mate, iTunes, Firefox, Thunderbird) its running around 54 C. The targus cooler is pretty quiet, slim, but a little cheap. They sell some high-powered solutions on newegg.com with better CFM and higher RPMs.
Now I'm sure a lot of typical mac users are going to have a fit about using a laptop cooler that makes the macbook a little bulker, but its way better than the damage your going to do to the macbook by running it hot on a daily basis!!

Intel processors (at least recent ones) are well known for having heat related issues. AMD processors offer better price/performance with reduced energy consumption and output. My HP zv5000z which is AMD64 based, has two large fans on the base, and kicks off a fair amount of heat exhaust. That however is heat thats NOT in my system. If I use it for games, then I'd be crazy not to have it hooked up to the Vantec Lap2Cool.
Apple in my opinion are taking a bit of a gamble. They've had to trade-off heat issues, performance with keeping the system quiet. To me, kicking the fans in on the macbook is a last ditch attempt to keep the system from keeling over, hence the loud noise (high RPM fans). What Apple is likely gambling over is that most users will run the machines in a "cool place" and the average user won't tax the system. Your business, designer, etc types aren't going to be playing games on it. They are gambling that the system will hold up to the level of heat abuse until the warranty runs out, or you purchase AppleCare. Either way, I assume they don't lose money.
In terms of melting, I seriously doubt you'll see physical melting of the system. What you are more likely to see is heat related damage to electric components (either the processors themselves) or surrounding components, resulting in system failure (or odd issues like display problems, random crashes etc). Lets just say its in the best interest of the health of your system to keep it cool.
The fact that Apple has corrected this on the MacBook Pros with firmware / hardware changes, would suggest there is some teething issues with the move over to Intel, and perhaps a shift in the type of customers buying the macbook.
With the market being so competitive, do you really think Apple is going to say -- "Hey these Macbooks look nice, but they overheat, you need to get Apple Care because they'll fail sooner than expected, and you should buy a laptop cooler to extend the life of the product". This adds what $300.00 to the price of the laptop, thats already slightly higher than lightweight options from vendors such as Dell, HP etc. When you go to the Apple Store and the person working there insists that you should buy Apple Care because the system is going to fail sooner rather than later, that tells you something right there.
Now if a laptop cooler keeps the system running between 43 C and 60 C instead of 60 C and 90 C, then aside from your own comfort with the thing on your lap, keeping the system cool is a good idea. Unless you like to return things to the Apple store?

Macbook Pro 15" Mid 2012 - Heating up issue

I bought Macbook pro 15" mid 2012 (non-retina) one year ago. I have Mountain lion installed. I recently facing that my laptop heating up so much nearly 90 degree Celcius when I'm using iPhone, Lightroom, Photoshop applications. It seems normal like 45-55 degree celcius when I'm browsing, word, excel and other applications. I use this on table (hard surface) but still when running those applications I feel the laptop so hot. Is there any problem on those applications or problem on Mountain Lion?
There is a problem in battery I'm facing. At the beginning stage I got nearly 5.5 hrs of battery life just with browsing or with some word documents. Now I'm getting hardly 3 hrs max with the same browsing or with some word documents. I use 4 points of brightness and not so much applications running but why the battery giving so low power? I wonder will the heat damaged my battery in the recent months (3-4 months I'm facing this heating up issue).
Please all answers are welcome.

Thanks for your information about the heating issue. I'm bit relaxed now. :-)
This is the information you asked for. Do let me know is there any problem on the battery:

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

HT1338 When the MacBook heats up the touch pad is erratic

When the MacBook heats up the touch pad is erratic

Take it in to an Apple Authorized Service center (Apple Store) and have it checked out. There are problems where the battery swells up and puts pressure on the bottom of the trackpad causing erratic issues like that.

IPhone 5S heating up issues

New apple iPhone 5S heating up issues in a day. Please give a solution or why it is happening ?

I was having the same problem and also loosing battery life - it suddenly happened. I went online and saw where someone said to get rid of all the unused apps still sitting there, deleted all the old posts and yea! suddenly the problem has been fixed. Hadn't deleted the unused apps in quite sometime, so obviously draining everything.

Can't install windondows 8.1 on my macbook pro - format issue

Can't install windondows 8.1 on my macbook pro - format issue
Running latest version of Mavericks.
Followed the exact bootcamp proceduce.
Have official window 8.1 version on cd.
All goes well until I have to format the 65Gb partition. Disk=0 and partition=4
Can't get over it. Altough I formatted it via a hint found on the internet with "dislpart" in NTFS. Wich also went weel and give the labelname "BOOTCAMP". But still no luck.
I have two questions:
1/ How to start my mac again in normal mavericks mode?
2/ How can I overcome the windows installation issue?
Tried already a lot of hints found on the internet.

First, make a time machine backup. You will need to erase ands reformat your hard drive. I had the same issue. The issue is that you can't install Windows using bootcamp without having the hard drive formatted as Mac OS Extended (Journaled). Do this from disk utility or recovery mode (hold down command and r at startup). Then you have to restore the backup to the hard drive. Then make a usb installer drive with bootcamp and then partition and install. Here's a tip: after you install bootcamp and are in the Windows desktop, go into the installer drive and then go into the bootcamp or support folder, then find a installer that contains the Apple bootcamp drivers. Also, you will need to convert the disk to an iso file. TO MAKE THE USB DRIVE FROM A DISC, USE THIS LINK

Macbook pro shutdown issue

Macbook pro shutdown issue when I push the power button it immediately goes into sleep mode

Hello Marrio22,
Thank you for the question. With OS X Mavericks, the power button has new functionality:
OS X Mavericks updates the power button behavior on Mac computers.
Using the Power Button to Sleep & Wake
Tap the power button in Mavericks to put your Mac to sleep or to wake it up:
Tap the power button once to put your Mac to sleep.
Tap the power button again to wake your Mac.
Press the power button for less than a half a second to sleep or wake your Mac. This duration is similar to pressing the Space bar or Return key to wake your Mac. The power button works this way across all Macs using OS X Mavericks, including both notebook and desktop computers.
Accessing the Shut Down Dialog
Press and hold the power button for 1.5 seconds, to bring up additional options:
Forcing the Mac to Turn Off
Hold down the power button for 5 seconds to force the computer to turn off. Important: You may lose unsaved documents if you force the computer to turn off this way. Use this method of turning off your Mac only if it has become unresponsive for an extended period of time. Normally you should shut down the computer by selecting Shut Down from the Apple menu, or from the shut down dialog pictured above.

Bootcamp VS VirtualBox - Heat up issues

Hi,
I have installed VirtualBox in order to run a specific MMORPG game.
Unfortunately, I realized it makes my macbook air [latest model with 4GB RAM and Mountain Lion OS by the way] heat up, and so I am afraid to do so again.
[I read on forums that I shouldn't be worried when the macbook gets hot because the fans keep the components cooled all the time, and yet, I dont really feel like doing it much or even at all].
My question is, will my macbook heat up the same way if I launch the same game via bootcamp? [because only 1 OS will be running and consume less resources or something..?]
Thanks.

You need to use MacBook Pro FanControl softare Lubbo. check their forum and if something does not work - and Apple has never offered or stepped up to the plate to offer a Windows utility in 5 yrs.
I always over-ride the fan speed - OS X default is too low and does not do an adequate job. Doesn't hurt, and then I can use multiple profiles and take preventive action to boost the fans. It is easier to increase air flow and keep it from getting hot, than it is to get hot and then try to expell the heat.
Automatic is not ever best. People almost always if they can make changes to graphic card fan speed when they game.
I suggest you just gaming forums and ask or look in Lubbo forum, someone in other thread said he just needed to change Mac ID to get it working, you know the 12,1 or whatever "name" Apple uses for a specific Mac model.

More Heat/Fan Issues with Tiger--Help

I have followed the heat & fan issues for sometime. However, I finally decided it was time to move from 10.3.9 to 10.4.3.
I upgraded yesterday, first using the upgrade option to move from 10.3.9 to 10.4.0 and then installed the 10.4.3 combo upgrade. I've repaired permissions and rebuilt the disk directory using Disk Warrior. There were no directory errors and only a couple of trivial permissions changes.
However, my Powerbook's fans are running constantly and my CPU heat is always pegged at about 135 degrees F, which is as hot as it ever gets. This happens within about 40 minutes of starting the Powerbook up cold and it stays that way for as long as I'm using it, regardless if there are any apps being used.
Activity Monitor indicates that the launchd process is using from 18% to 20% of my CPU, even with nothing else running. I've disabled all Spotlight indexing and I've turned Dashboard off. It appears that it's the lanchd process that is accounting for the extra heat and fan use. It simply won't drop below the 18% to 20% of CPU. There is no other process that is using any significant amount of my CPU when nothing else is running.
My processor is set at Automatic, the same as when I was using 10.3.9.
I was using Silk, Application Switching Menu (ASM) and Macaroni, but I've uninstalled them. No change.
I've reset the Power Manager (including deleting the com.Apple.PowerManagement.xml file) and reset NVRAM. Again, no change.
Finally, when I boot back into 10.3.9 (on my backup hard drive), the fan activity and heat return to what I consider normal--much lower than with 10.4.3. Specifically, the heat and fan activity is directly related to CPU use. If I'm not doing anything, the heat drops and all the fans go off.
There is one other curious effect of 10.4.3 vs. 10.3.9. When I'm running Firefox (latest version), all Firefox user-interface stuff (menu selections, opening many tabs in succession, etc.) are MUCH more sluggish than when using 10.3.9. Frankly, I was expecting the opposite.
I would really like some help with this. I've read all the troubleshooing info on MacFixit and Macintouch related to heat and fan issues associated with Tiger.
12 1.5Ghz Powerbook Mac OS X (10.3.9)

I'm the originator of this thread and I appear to have an answer.
I tried an "Archive and Install" of Tiger, on top of my existing 10.4.3 install that was giving me the trouble I described above. I had the time today and figured "what the heck[ll]".
I then installed each additional piece (10.4.3 combo update, airport updates, quicktime updates, java updates, etc), stopping after each one to check CPU temperatures and CPU use in Activity Monitor.
I'm now back to a full 10.4.3 install, with all current recommended Apple software and I don't have the heat/CPU use problems I previously had. There is no significant use of the CPU by the launchd process.
I also re-enabled Spotlight indexing and that doesn't cause a problem either.
Also, my entire system is *MUCH* quicker and responsive. I wish I knew what piece in my previous system install was causing the problem, but hopefully my experience can help someone else. When in doubt, do an "Achive and Install" rather than an update to the previous system installation.
By the way, with heavy Spotlight indexing going on and mild web browsing, my CPU temp is just 112 to 115 degrees F. Previously, with no Spotlight indexing and with NO apps running, my CPU temp was maxed at 135 degrees with fans on full. And if you're reading this thread, you know what max fans sound like on a 12" PB.

User Tip: How to deal with MacBook Pro and MacBook heat?
Per your user manual:
Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings.
From MacBook Pro: Care, Use, and Safety Information
For prolonged use, place your MacBook Pro on a flat, stable surface. Do not place your MacBook Pro on your lap or other body surface for extended periods of time. Prolonged body contact can cause discomfort and potentially a burn.
Call Apple Care if you have it or your computer is still under warranty. Take FULL advantage of your warranty. Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired.

Aluminium MacBook heats up very fast

Why does the left side of the MacBook heats up so fast? And it can be really really hot at times.
Does any other MacBook user encounter such problems too? Is there a solution to this?

Me too!
I have only had my mac for 3 months and already when using safari for a while it starts heating up a lot. When i then check the activity monitor it says that CPU is 100 % and then I have to close safari down and restart it. first then it gets silent. but this should not be the case with a new mac, is something wrong?
Yes, if Safari alone is indicating 100% CPU then something is wrong. Of course, this assumes that you don't have several windows or tabs open within Safari each of which is displaying some type of animation or video. If you do have multiple windows or tabs open in Safari try closing those which you are no longer using. However, even one animation or video can take quite a lot of processing power so don't be surprised if your MacBook gets a little warm or "hot" while it is displaying same. This is also true (or even more so) when playing video games.
In any case, the definition of "hot" or "too hot" depends entirely on your experience. I know that my previous PowerBook G4 ran much hotter than my Aluminum MacBook. A few parts of the PowerBook G4 could get so hot that it would actually burn your skin (if you were unwise enough to remain in contact with the case after the pain began). In that sense, my Aluminum MacBook never gets "too hot" and in my experience it is actually a "cool" or slightly warm running notebook computer.

MacBook Heat Issues

Today I received my MacBook (1.83 GHz).
I have had it sitting on a flat stable surface, as Apple tell you to, for the last 5 hours.
The hinge is hot to touch which is fair enough.
However the left hand side where all the sockets are is also hot to touch.
It feels like warm air coming up between the keys on the keyboard.
Sitting typing this at my iMac I can feel the heat on my arm from the MacBook sitting beside me just as if I was sitting beside a fire.
I think it would not be possible to use it for a whole day in the same way as all my other computers.
I tried turning the Energy Saver settings down from performance as they suggest. This has made a slight improvement but I would expect to be able actually type at the keyboard in Normal setting instead of having to go to reduced power.
Before anyone asks, yes I did check the vent for the plastic.
Is this the same kind of experience others are having with the MacBook?
I'm going to give it a full test of sitting on my desk powered up all day tomorrow and then see about sending it back.
MacBook 1.83 GHz Mac OS X (10.4.6)

I agree the MacBook get very very hot underneath in the upper left quadrant. It's not too hot to touch but I would venture to say that if this MacBook were to be on the bare skin of a child it will hurt them or cause them to shed/thro/drop the MacBook to the floor in a hurry at the very least.
I've been running Front Row to view shared iTune's purchased TV Videos on my LR TV set for several hours. My iTunes server is my PowerMac G5. The base of the MacBook is very very hot during this playback and is certainly not comfortable residing on my lap.
It's debatable whether Apple will do anything about this (if they even can) until someone clearly hurts themselves and it becomes public knowledge.
This is a shame as the overall MacBook is a wonderful product IMO. However, this is one flaw that cannot be ignored.
