Overheating

Hi
My first macbook pro did not get really hot.
The one I have now (under a year old) gets extremly hot under - with same kind of use.
Why does this happen and how can I prevent it?

What is hot? 
First try a SMC reset:

If that does not resolve the issue, download from the Internet iStat pro and install it.  When you MBP gets hot, post an image of iStat pro such as this from mine:
Also open Activity Monitor and set it it show 'All Processes' and set '%CPU' to show values from high to low.  Ex:
With this information, we can determine if you do have a problem.

  • Is your computer overheating?

    My computer went down the other day, simply a black screen, no warning, no messages, just black. After a lot of messing around and diagnostics it turns out my computer was overheating.
    An overheating or border line overheating machine can result in lock ups, slow downs, and unexpected reboots. To find out if your CPU is too hot you'll need the "hardware monitor" that comes with your motherboard. There are also plenty of third party programs which you can run.
    The next question is "how hot is too hot?". Intel CPUs display one of two numbers... an absolute temperature ~or~ a thermal margin. The first is self explanatory but the second can seem confusing. The Margin indicates how many degrees remain before the CPU is critically hot. So the bigger the margin the safer you are.
    Remember that modern computers conserve energy when idling, so run you most intensive application for 30-60 minutes and keep and eye on your temperatures. Conventional wisdom indicates you want your mobo and CPU less than 60°C (140F). Any higher and damage to one or the other may result. Intel has specific details on each CPU including its thermal maximum on this page, click here. Most modern CPUs give you a thermal margin which removes the guess work.
    Tip... if your hard drives are too hot to keep your hand on for any period of time then you have excessive heat build up. Ensure hard drives have one drive bay gap between it and anything above it. Or use a case with hard drive cooling fans (see below).
    If your board and/or CPU are running too hot you should consider a well ventilated case. I am now using the Antec 900 (click here) which has four over sized fans plus the fan in your PSU making five total. The 120mm BIG BOY (their words not mine) is placed directly above the CPU keeping it super cool.
    Hopefully these tips will help those users experiencing weird hang ups and crashes.
    Tip... if your temperature is good but file access is slow and you get lots of blue screens then there may be a chance your hard drive is about to fail. Make sure to run a check disc or similar application. And always make frequent backups!

    >Gordon McKinney:To find out if your CPU is too hot you'll need the "hardware monitor" that comes with your motherboard.
    I use the Intel supplied monitor (in the Intel Desktop Utilities) on my DG965WH motherboard with a Q6600 CPU and 8GB RAM, but I've found a problem when using it in Vista Ultimate 64.
    Apparently the monitoring functions interrupt the mouse hardware (maybe all hardware for all I know) and cause random and temporary mouse pointer freezes that can last for a random amount of time--averaging around a second. The mouse pointer will catch up, but the interruptions really create havoc when using any mouse oriented program--particular LR2.1 and local corrections.
    My solution is to run the Intel Desktop Utilities when I wish to check the temperatures--only a couple of times a day as I've never found them to be within 20 degrees (C) of a danger point--and then immediately kill iptray.exe.
    Intel doesn't say IDU works in 64 bit OS versions, but I get the same readings with it in Vista 64 as I do in XP SP2. However, it doesn't have the mouse freeze problem in XP so I could leave it in a monitoring state.

  • K7N2 Delta Overheating

    I have the K7N2 Delta board (rest of system specs are in sig) and after about 45mins-1 hour of gaming, my system locks up and resets.  After lock up, if i go into bios, my sys temps usually read about 59-64 degrees celcuis.  I was having this problem with the stock fan/hs, so i bought the Volcano 12, figuring that would solve the problem.  Didn't, only gave me about 1hr-1 1/2 hours before lock up at lowest RPM setting (2100), and only about 10-15 mins longer at highest RPM setting (about 5600).  I have the same problem when I run 3d 2003 test, it goes through the first set of tests fine, but when I get to the first CPU test, my system locks.  
    My idle temps on the CPU are about 45-52 degrees celcius, case temp is in about 38 celcius.  I read in other posts that it could be due to TOO MUCH thermal goo on the chip, but how do I know how much is too much?
    Aside from overheating, what else might it be?
    If I leave my system idle, it can go for days with no hint of a problem.  It's only when I start gaming (America's Army, UT 2k4 demo, BF1942) that I get problems.
    Also, I ran memtest, RAM is fine.

    Wonkanoby:  Ya, I know I need new RAM, but I'm on an incredibly tight budget now, so it's gonna be a while till I can afford some (basically, I haven't had a job in 8mths).
    DeathStalker:  I tired what you said, opened up the side of my case, put a Vornado house fan on high speed facing my mobo, and the temps did drop quite a bit (with HS/fan @5600 RPM and idle CPU=41celcius, Sys=28celcius.  @2100RPM and idle CPU=44celcius, Sys=34celcius).  I decided to run the 3dMark2003 this way, with HS/fan @5600 RPMs, and I got through the first CPU test, but then they system crashed again.
    So it seems that the extra cooling helped, but still wasn't enough.
    Any suggestions on how to cool my system with out putting a house fan in there?  I already have 3 80mm fans (1 front bottom intake.  1 top exhaust, 1 rear exhaust).  I have room for 2 more 80mm fans (1 front bottom intake, 1 rear exhaust), but I don't think that would help cool the CPU all that much, would it?  I thought the TT Volcano 12 would help with cooling a lot, but it has only provided marginal imporvements.
    Also, could it be that I am overstressing my RAM, and that is why I'm having these problems?
    Open to any suggestions.

  • Satellite A505-S6973 overheating and fan works often

    I hate doing this but I seem to have encountered another problem which i have been searching and reading with the hopes of correcting myself. I presently own a Satellite series laptop with an Intel Cor 2 Duo T6500 2.1Ghz processor.
    I 've been monitoring my system for performance issues andi've noticed that for sometime (unsure when) the temperature on my system has risen significantly. I'm seeing from my PC Health Monitor that my processors temperature is running at 59% and fan speed is at 78% yet when I place my hand near the cooling fins at the side of my laptop I can barely feel any breeze but a co-worker of mine has a vostro and the fan feels like it's running on NOs.
    If there is anything that can be done I'd greatly appreciate this, i'm afraid of loosing my system due to something simple that cause overheating.
    N.B. I noticed that at one time different users posted threads stating that after updating there BIOS they experienced overheating problems. If this is the cause of anywhere near it please help.

    Are you sure that your notebook is overheating?
    In my opinion you cant compare this with other notebook models because every notebook has its own cooling modules and fans and there are not standard parts as on desktop computers. Furthermore its also important which form factor your notebook has. Larger and bigger notebooks have a better cooling assembly as smaller ones.
    Anyway, in my opinion you could try cleaning your notebook using compressed air spray. This should always be done from time to time to blow out the dust from the cooling ventilators. Therefore its not necessary to disassemble the notebook.

  • White Macbook (2008) overheating and shutting down

    Hello,
    I have a white macbook from about 2008 (it is not unibody, it's the one you can remove the battery). My case has cracked all around and little pieces of the plastic have flaked away (as seen on all other 1 year+ macs of this generation). I figure this helps the heat escape rather than make the problem worse but I still plan to get the case fixed on with applecare.
    My problem is that sometimes when running only iTunes and safari my CPU heats up to 90 degrees celcius (194 F) and my computer simply shuts off. I don't have the clear plastic covering vents and I just use my mac on my desk, not on a pillow or anything like that. When my computer heats up like that, the fan is rotating at about 6200+ RPM according to SMC fancontrol. Right now my computer is propped up using a large eraser to create a space for air to circulated along the bottom of the case.
    What can I do to keep my Macbook from overheating? I don't want to damage my computer. I don't really do much video or real intense stuff, mainly just music.
    Any help is appreciated.

    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 (>=70,) 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.

  • Satellite P300D-10V is overheating

    Hi everyone
    I am using Toshiba p300 d-10v laptop till one year. After one month I've bought this notebook, I had some problems with it. For those problems I'vee sent my laptop to the service twice in three months.
    First problem was it is overheating and closes the system. Second problem was about the ATI Graphic card. For those two problems the service person told that they did not see any problem and they sent it back. I am not going to sent it to this service in Turkey again.
    I want some suggestions to find a solution for me.
    As I heard from internet about this problem there are many users in Turkey having the same problem at that model of notebook. I can only use %70 percent of processor so if it goes up than it shuts the system, why I should use less than %70 percent of the capacity. If I knew this I would buy another model notebook. There was no any information about this model of notebook when I bought this model.
    Cheers
    Tolga

    Hi mate
    I dont understand how you can use only 70% of the CPU performance.
    Usually the CPU supports the AMD PowerNow Technology which allows you to use the CPU in Automatic mode.
    In Automatic mode, the speed and voltage are controlled dynamically and automatically. It depends on the application how fast the CPU would run.
    In Automatic mode, the needs of the application environment dictate the amount of performance required and power used.
    This mode of operation ensures that only the required amount of power is dissipated.
    Simply said if the application doesnt need the full CPU performance then the CPU will not run always with 100% and will not create high heat dissipation.
    But the notebook could overheat if you would use non-Toshiba graphic drivers.
    The drivers which are not certified by Toshiba dont support the overheating protection and the usage of such drivers could lead to a overheating. Therefore you should use always the Toshiba drivers because such drivers are designed especially for the notebooks graphic cards. Drivers from ATI page are created only for desktop PCs.
    Finally its strongly recommended to use the notebook on the table and to ensure that there is enough free space around the notebook to ensure a good air circulation.
    Especially in countries or regions (i.e Turkey, Africa ) where the temperature is higher its really important that the notebook would be cooled properly.

  • CPU Overheating problem on Windows 8.1 Pro (installed with BootCamp)

    There is a really important overheating problem on windows 8.1 (installed with bootcamp) even i do nothing Cpu is 50-60-70 Celcius degrees. This is really annoying problem. Most of users necessarily need windows OS for using third part programs that doesnt exist on OS X platform. I think this problem is important and has to be fixed as soon as possible.

  • Mid 2012 macbook pro glitching, freezing, overheating

    Starting a few weeks ago, I noticed a change in my mid 2012 macbook pro. My laptop was losing charge EXTREMELY quickly, I would charge the laptop to 100%, and just an hour later (after not using it, but the lid closed and it was sleeping) it would be up to 60% charge, then when not in sleep and on, it would lose energy extremely quickly. I always make sure that unecessary background apps are not running--so that was not the problem. This problem went away after a week, but it was the first signal that something was wrong with my laptop.
    Next, the laptop was having problems with waking up from sleep, I did an SMC reset and this problem was fixed.
    After that, the laptop started glitching (static and banded lines on the bottom of the screen) and making this clicking noise when I was streaming video fullscreen on Netflix. I thought at first, that this was a problem with Silverlight, and reinstalled the silverlight plugin (several times). Then I noticed that the computer would glitch when I was streaming full screen on Netflix and picked up the laptop (moved it from a flat surface). This signaled to me that the problem was perhaps not software, but a hardware issue. I verified the disk and did a permissions report and neither were curative.
    Further support that the problems are with hardware rather than hardware came to me when my computer presented itself with a fourth issue: the laptop, when being lifted or moved from a static surface, would sometimes freeze entirely and make the same clicking noise. This problem was not during fullscreen streaming, but had spread to when I was simply using more than one app at the same time (e.g. having Chrome and Word open together). When this happenend, the only solution would be to power down the computer and restart.
    Finally, while sleeping with the lid closed in my backpack, I hear a whirring noise--I pick up the laptop and it was hot to the touch, overheating with the fans running on high speed.
    I have no clue what is going on. I have taken the computer to my university's mac shop and they have suggested it is a logic board issue and I should give the computer in. I have scoured the forum for an answer of what is happening and am determined to find one. So I pose the problem to you--any help would be appreciated. Thank you.

  • Mid 2010 Macbook pro "overheating"

    First off let me just say I know there are many threads about this already - but all of them have the same kind of answer "the Macbook Pro is not overheating unless it turns off, keep it well ventialted and on a flat surface" etc, etc. I'm not complaining about my macbook "overheating" per se, but rather it is getting hotter a lot faster than it used to. I had a number of problems recently with my macbook and got it sent away to an authorized apple support centre where they replaced the cable that connects the logic board and hardrive (I'm sorry I don't know the technical term for this or even if this is exactly what they did. I know they replaced some faulty part that connected something with the logic board). And all the problems relating to that ceased - however about two weeks later and my macbook started heating up a lot quicker. The fans come on after about 5 minutes of casual use (internet browsing or word processing), and after about 15 inutes of doing something like watching a movie the fans are roaring away and the back bottom of the macbook is nearly too hot to touch. I've remedied this a little bit by only using the laptop at my desk and sometimes propping it up to give more air flow to the bottom but I never used to have to do this. Previously, I would have to be doing something pretty hefty for the macbook to start the fans even at the lowest speed. I was wondering if anyone knew of how to fix this? Whilst it's not a huge problem it is an annoyance and I don't know if it's a coincidence or not regarding the fact this started only a week or so after it got fixed. Any ideas??

    complexcraziness,
    try this next: log in as your administrative user, and create a new standard user — say, “Test”. When you’re done for the day, shut down your MacBook Pro. In the morning, boot up and log in as the Test user, without doing anything. Does it still rise to 71°C within a few minutes of doing nothing as the Test user?
    Did you leave the MagSafe adapter attached overnight? If so, then another approach to take would be to change the Battery values in the Energy Saver pane of System Preferences so that the Battery and Power Adapter settings are identical. Shut down tonight, but detach the MagSafe adapter after shutting down. In the morning, boot up and log in as the same user as this morning, but don’t plug in the MagSafe adapter — just run on battery power. Does the same rapid rise in temperature occur when running only from the battery?

  • IPhone 4 battery draining quickly // Overheating

    Hi!
    So I got my iPhone 4 late August, and everything's been going fine up until last week.
    I have the ios that is right before ios7 (I think 6.1.5), I didn't install as I've heard bad reviews.
    I woke up at 9am today. By 11:30am, it was down to 20%. It gets very hot within 20 minutes of it being turned on.
    I have my wifi off, 3G is always on, brightness is at about 25-30%, I never use mail / calenders.
    It's really only started since I've been leaving Clash of Clans open so I don't get attack, but it happens to all apps now aswell.
    I've tried turning off / on, restoring, anything that's been suggested but my battery still drains too quickly!
    Here's how my day goes:
    I go to school at 8am. I use it on the train, and class starts at 9am. I use it for taking notes as my laptop is broken. By lunchtime (12:30pm), it's already all used up and I have to charge it, which I don't like doing as it can get stolen. By the time I get home, I have to recharge it, and when I go to bed I leave it charging for the night.
    Would somebody be able to assist me? Thanks!

    My Iphone 4s is overheating and draining the battery what do I do. I have done a hard reset and also reset to orignal settngs and it is still overheating and draining it's battery

  • Lenovo G560 CPU FAN stop then overheating

    Hello i have lenovo G560 after i turn it on a few seconds fan working then definitiveli stops and cpu go overheating and notebook go stutdown.  I try to change CPU fan but issue is there still. Sorry for my poor english. Can anybody tell my what i want to do?

    hi deadbiker,
    Overheating problems are commonly caused by evaporated or dried out thermal paste or dirty cooling fan. Since you replaced the fan, I recommend you remove the heatsink and re-apply a thermal compound on the CPU and GPU (if applicable). See page 41 on the Hardware Maintenance Manual on how to remove the heatsink.
    If the fan still stops and the unit overheats and shuts down, the CPU might be throttling or might be faulty already. I recommend you send the unit for service (either a local repair shop or thru lenovo since they have diagnostic tools to check the unit out). Support phone list here.
    Hope this helps.
    Cheers

  • Power cord plug in overheated, black smoke and extremely hot...

    My daughter has had the Macbook for less than a year. She says it has always sparked when plugging in/out but tonight
    black smoke started coming out of the box where the prongs are. I am extremely upset...this could have caused a fire.
    I understand we can probably get a new one as it's under warranty, my concern is still the fact that it overheated in the
    first place.
    We do not have an Apple store in our small town and she needs a replacement asap. Should I just call the support
    helpline? I'd like to think they'd take this seriously...
    Here's a photo..the prong where it's burned was extremely hot, the other prong cool. ://

    Except that it is normal under many circumstances.
    Any capacitive load on a circuit will tend to resist changes in voltage, with the result that plugging in a capacitive load will often cause a small spark to form.  Similarly, an inductive load will tend to resist changes in current, which is why unplugging a running electric motor will also often cause a small spark to form.  The transformer in a power adaptor, when connected at the other end, is a capacitive load.
    The trick, of course, is being able to differentiate between these effects and sparks caused by short-circuits in the socket or plug, which can be extremely dangerous fire hazards.  Certainly if there are other indicators of a short-circuit, like heat being generated, then it must be checked out.  In fact, if there's any uncertainty, it should probably be checked out.
    However, explaining that there can be sparks in a perfectly functioning socket is not the same as telling people that sparking can, or should, be ignored.  If anything, it's telling them not to ignore it, but to investigate it.

  • DVI to ADC Adapter Overheating

    My DVI to ADC Adapter overheats when I plug in a 22" Apple Cinema Display M8058. I've used this adapter with my powerbook and after about 30 minutes or so it is hot enough to cook an egg on the apple and it shuts down and the display goes dead. The same happens with my G5. Once it's cool it fires up. It works ok on a smaller ADC display without shutdown. I can't find anywhere where overheating is an issue and wonder if this adapter is a fire hazzard or I got one that's gone bad ? Anyone else have this problem?
    G5   Mac OS X (10.4.5)  

    Yes , that's true , my Adapter is overheating too , but I have Drop-Outs at the resolution 1600x1024 ono my Cinema Display 22". I think it's a case of warranty.

  • My experiences & solutions to new overheating iMac

    I know there are many threads concerning these overheating problem with some new aluminum iMacs but it's kind of hard to decide which one to post my experience to so I'm just posting a new thread. This is not a question because I think I fixed the problem with mine. I just wanted to share this with people in hopes that it might correct your problem as well instead having to take it back to the store.
    Well, I bought a new 20" 2.4 aluminum iMac on August 24th. I connected my previous iMac to it and started migrating my user account & files to it. During this process is when the new iMac completely shut off on me! I thought it was just a glitch or something. So I turned it back on and it started the migration again. Everything went well this time. But since then it has turned off on me at least 3-4 times. When I was backing up files to an external drive. And a few times while working in Photoshop and Aperture it would start freezing up & the graphics would become distorted and blocks all over the screen. And from my days of overclocking PCs I knew this was a heat related problem more than likely with the video card.
    So I installed a program called smcfancontrol and was able to up the speed of the fans. This corrected the problem and I didn't get lock ups or freezes after that. But I knew you shouldn't have to do this so I was looking for a solution so I wouldn't have to take the iMac back to the local Apple Store. Because that would be a pain having to backup files and start over again.
    I reset the fans back to normal speed and quit the smcfancontrol program. I installed iStat Menus so I could monitor the fans & temp. It would seem that when the GPU would reach 150 deg F then it would start having problems. Well, I reset the SMC, PRAM, and NVRAM to see if this would solve the problem. Because what it seemed like what was happening was that the part of the system that controls the fans & temp was not responding correctly when it got hot.
    Since I did the reset to those areas of the system I have not had any shut downs or freezes. I ran the system through a number of tests. I worked in Photoshop & Aperture at the same time doing a number of different processes while playing music in iTunes. I did the Hardware Test a couple of times. Xbench. And I also ran an pretty intensive test called CPUTest where it got the whole computer pretty hot through repetition. The fan for the CPU was speeding up over the normal 1200 rpm like it should and it never shut off or gave any more errors.
    So I'm crossing my fingers now that the issue with my new iMac was resolved with resetting the SMC, PRAM, and NVRAM. And it saves me a trip back to the Apple Store!
    I hope this information is helpful to someone.

    Well, I've been wrestling with my iMac for the past week in trying to solve my freeze & shutdown problem so I wouldn't have to take it back to the Apple Store and also if I did then I would like to know what the problem is first so I can tell them if it is definitely a hardware problem. The freezes & shutdowns would happen at random times and I don't think it is a overheating problem now because of this. It did seem like it would happen more often when I would work in Aperture & Photoshop. I would get through editing 3 or 4 photos and it would lock up completing. Then I would have to do a hard reset.
    Anyway, yesterday morning I reinstalled the OS via Archive & Install. It seemed to be running better. So I started working on some projects but again after doing some work for about an hour, it froze on me. I took a break because I was fed up with it at the time and came back to it later.
    I decided to reset the SMC and PRAM again since I had not done that after the OS reinstall. Then I removed all extra cables except the extra display, keyboard, mouse, & speakers. I skimmed through 2000 photos in Aperture and I monitored the temp & fan speeds. The whole computer got pretty hot especially the CPU and video card (GPU). The CPU fan sped up to 1500rpm at one point like it should. And after getting through all those photos, it did not freeze or shut down on me at all. Woohoo!
    And this morning I noticed that the computer went to sleep like it was supposed to. It never did that before. So I'm thinking maybe the OS reinstall and the second time of resetting the SMC & PRAM might have solved my problem. I'm crossing my fingers! I will be gradually plugging in my extra devices to make sure one of those is not the problem.
    Anyway, I hope sharing my experiences have helped. I definitely know the AppleCare & "Genius" Bar hasn't been much help to me. Seems like all they know how to do is turn it on! I hate having the feeling that I know more than the people who are supposed to be qualified to be in that position. And as for AppleCare I got some guy from another country who had bad English and was obviously reading through a step by step handbook and wasn't listening to what I was saying very much.
    Side note: It's obvious that Apple moved the power supply from below the screen to the upper left corner of the iMac. That's the reason it is warmer in that area. I wouldn't be concerned about that. These power supplies have always run that warm in the flat iMacs. Easier to feel on these new models though because they are thinner.

  • Macbook Pro overheating Apps "Quit Unexpectedly"

    PROBLEMS WITH MY UNIBODY MACBOOK PRO
    GPU/CPU Problems? Logic Board bad? I'm not sure what the issue is. Please Help!
    Hi, I have an:
    ·   Early 2009
    ·   17 inch
    ·   Unibody Macbook Pro (UMBP) (5,2)
    ·   Intel Core2Duo 2.66GHz
    ·   Nvidia GeForce 9600 GT 512MB graphics (kept on Performance mode – not power saver – because it usually sits on my desk plugged into AC wall-wart 85watt mag-safe power like an iMac), (Nvidia GeForce 9400M onboard too)
    ·   I have an external 27” monitor connected and mirrored - with the internal screen off (brightness is all the way down – thus running cooler)
    ·   (Note: all the problems existed before any/all my upgrades – including the external monitor.)
    ·   I have upgraded to 8Gb’s of 1066 DDR2 RAM
    ·   500Gb Seagate Hybrid HDD
    ·   The UMBP is Running the latest OS 10.8.4 (with automatic updates) – and it had the list of problems (below) with OS Leopard, and Snow Leopard too!
    1)  It will not play *Netflix streaming*, or  youtube or any other internet video without stuttering, stopping, and hesitating in video and audio!! I have CHARTER Cable Internet which runs between 20-50Mb’s :-) This is NOT slow internet.
    And with my Windows 7 (64bit Intel QuadCore) Desktop PC using the exact same wifi internet connection there’s *No stuttering*, no stopping, no hesitation in video OR audio! It’s an older Gateway desktop with a tiny USB wifi dongle. And the desktop runs *on-board* Graphics – no graphics card in the machine...at least not until I upgrade the power supply – then I can install one. ;-)
    2)  System Information crashes - “Quits Unexpectedly”. SOooooo frustrating! I can’t even get the current specs so you guys know what we’re dealing with. So I looked them up in a file I have kept since I did all my research online to buy this UMBP. So, I copied all the data that was just now sent to Apple (not that anything will be done with it – they don’t care – my Mac is out of warranty). This app crashing has happened *numerous* times in the past couple years and I just didn’t know what to do about all these problems (the list continues below) because it’s been out of warranty since before I bought it used on eBay.
    3)  I canNOT get Adobe Reader to run on my UMBP - it crashes within seconds! I finally uninstalled it and re-downloaded it and then reinstalled it – still same problem. So, I waited a few months and then re-downloaded it and re-installed it again – still same issue. And I know that Reader had been updated more than once in that time.
    I think that the following is unrelated but I figure I should put in all the information I can. The battery never says 100% (it’s always between 97-99% full. When I first got the UMBP it kept telling me to get a new battery (for $250!) And the seller sent the UMBP with a 65 watt (not 85 watt) mag-safe power supply…which I didn’t even realize until months later (hey, this was my first and still is my only Mac, so ya gotta give me some grace here. I hate(d) Microslave *so much* after living with WinVista for 2 years that I HAD to get a Mac..and I don’t ever want to go back! ;-) The only reason I even have a Windows box is because a friend of mine (who was borrowing my then spare beat up old car for like 3 months) gave me one when he got it as partial payment for a job he did on a small business network (yeah, he’s even more geek than me!)
    At first I was thinking that it was the NVidia GPUs, but now I’m beginning to think that all three: the CPU and both GPUs are in need of re-soldering to the Logic Board. It seems that I’m not the only one online that agrees that the system cooling fans are subpar in UMBP’s (lots of complaints about burned fingers, etc.)  – so, I run a small 6 inch fan (on high) across the top of the keyboard 24/7 so that it won’t completely fry! (Well, at night when I put my UMBP to sleep I usually turn off the fan…but anyway.) It doesn’t wake up at night to do any background downloads or Time Machine (USB ext drive) work – it would most likely wake me up if it did (I’m a very light sleeper). The fan does a good job at keeping the surface (aluminum) “warm” (as opposed to HOT) so that IF I were to use the built-in keyboard I wouldn’t burn my fingers (like I used to – until I bought an external Bluetooth Apple keyboard – those keyboards are so nice!).
    So, yeah, I could send it to someone on eBay (along with $200) who will reflow or reball the chips to the Logic Board, but that seems to be a band aid on a situation that is quite likely to happen again…right?
    As I see it: Apple didn’t put enough cooling into the system – the fans are too slow/small – and thus I have a serious problem with the Logic Board.
    And I was just on eBay looking at Logic Boards and they cost at least as much as most of the UMBP’s like mine. So that would be way too expensive – I might as well just buy another UMBP like mine – but that’s not going to happen.
    The closest Apple store is 2.5 hours drive away from where I live. And the closest authorized apple repair shop is 1.5 hours away and it’s not likely that they will run system tests for free…and the Best Buy here in town is not authorized to work on Macs – they didn’t show up in the search results at locate.apple.com/service/….
    So, what can/should I do??
    I didn’t write all this just to “vent” – I really need this fixed!
    ONE SMALL ADDITION:
    IF ANYONE suggests that I do the following:
    > System Preferences > Energy Saver > Graphics: Better battery life
    (Previously it was set to "Higher performance")
    Then I will…do something (hmmm it’s the internet, what can I do??)…for their IDIOCY!!!
    Doing that *is doing this*: Paying $3,000 for a Macbook (NOT Pro!!)
    I mean think about it for one second: the specs on the Macbook is the cheaper/slower Graphics Chip (GPU) and buying a Macbook costs THOUSANDS OF DOLLARS LESS than a MBP! Right?
    IF Apple suggested doing that then that is just Apple’s lame-a$$ way of trying to get away from the fact that they underpowered/under-designed the cooling system (fans et al).
    That’s the same answer I got from HP when my notebook overheated to the point of dying!!! HELLO?!?!?
    Get it? ALL these notebook manufacturers’ designers and engineers are all using the same data/designs! Yet, I’m paying TWICE THE PRICE for an Apple product (expecting a cool running notebook) vs. a custom-built HP 17” notebook PC that I bought brand new a few years ago (with Vista – ARGH!)! One which would run simultaneous DUAL EXTERNAL monitors at 1080p! That GPU kicked butt! AND it had DUAL SATA2 INTERNAL Hard Disk Drives (with the internal DVD burner)! And this was made in 2009 people!
    I thought Apple cared more! Especially at this price!
    Maybe you DON’T “get what you pay for” anymore…?
