MacBook Pro :: Overheating Before Booting

Oct 20, 2010

What could possibly make a macbook pro overheat before it is even booted? I have bootcamp installed so I can run solidworks and a few misc programs in XP. The machine always runs a bit toasty for my liking under windows so I use smc fan control to crank the fan and then reboot into XP pro. This works great as long as I dont need to sleep the computer and re-open later. In this situation the fans dont resume the higher speed I specified and I get temps in the 70-80C range.Thats not really the problem though. Today I started the machine (from a complete shutdown) and held option to bring up the bootcamp chooser. Meanwhile I was distracted with something at work so the computer sat like this for 15 minutes. No OS had booted, just the gray chooser screen. When I came back the fans were running full blast! The overheat protection had come on. I quickly booted into snowleopard and the temps were in the high 80-low 90's. After a minute it was back to normal 50's but I'm puzzled. All software is up to date.Nothing was even running?!? How is this possible? Nothing should have been straining the system.

MacBook :: Overheating And Slowing Down - How To Make Fast And Prevent Overheating

Oct 1, 2009

I have a new macbook, see stats below.

Up till last week everything was fine, I could run 'Second Life', photoshop, email, a browser, download stuff, play Itunes AND watch a movie all at once without any trouble.

But recently the computer has gone a bit weird.

It started getting very hot, much slower and turning itself off.

MacBook Pro :: Overheating - How To Cool Down

Jan 5, 2008

I have a 2.0 macbook with 2g ram 80gb harddrive with 29gb free. My problem is that my macbook runs idle at around 130-140 degrees fahrenheit. When I go to Youtube it goes up to around 160 degrees and when I go to Google Books and open up a page my macbook reaches around 180 degrees I also do a lot of audio production and temperatures reach a steady 165-180 if I have a fair bit of processing going on.

What the hell is going on? I need to use google books for school and don't think it is safe to use my MB at such high temps. Also with all of the audio work I do I imagine that the lifespan of this computer will not last very long.

MacBook :: Seems Like Overheating When Nothing Is Running?

Jun 7, 2010

Since then, I feel like my Macbook is overheating when even it isn't using heavy apps.

Right now, using just Safari and the Mail on, CPU and Heat Sink A is nearly 60.

Can it be from the new components ? I upgraded the Memory and the Hard drive.

MacBook Pro :: Significant Overheating And No DVD?

Aug 17, 2010

My MacBook Pro gets hot. Right now I have Safari, Dreamweaver, Photoshop, and text edit open but I'm not doing anything strenuous on any of them. My CPU temperature is 124 F. My fans are running at 4000rpm, but only because I'm using smcFanControl. When I use firefox it gets even hotter.

I bought my laptop in 2008. It's 2.4 GHz Intel Core 2 Duo with 2 GB 667 MHz SDRAM.My question is: this isn't normal, right? Is there anything I can do (other than getting it professionally looked at) to fix it?Also, on a probably unrelated note, the DVD player no longer burns or plays DVDs. Aside from buying a new one, is there anything I can do to fix it?

MacBook Pro :: Overheating For No Reason?

Dec 6, 2014

Since i've installed Yosemite, I noticed that my fans are always running  on high level (6000rpm) for no reason. As soon as I open it the cpu starts overheating (between 195 and 205 degrees) even if there's no apps using significant energy. I already tried to reset the SMC or the PRAM with no results.

MacBook Pro (13-inch Late 2011), OS X Yosemite (10.10)

OS X :: Black Macbook Overheating / Shutting Down

Sep 7, 2010

over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do?

MacBook Air :: Overheating - One Core Shutting Down?

Jul 28, 2008

I'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?

MacBook Air :: Rev B Overheating When Playing Games

Dec 22, 2008

this rev B i got is much better than the rev A i used to owned. the youtube and movie lagging is gone. but it's still not powerful enough for a game. i played eschalon book:1 which is not quite heavy and demanding like the new games out there. let alone playing half life 2. it's overheating and locking down the cpu to 800mhz just like my old air. see the screenshot. after playing for 20 minutes, it's becoming very laggy and unplayable. i guess this thin mba is not ok unless playing simple games like gamehouse's card and board games.

MacBook :: Overheating With Safari - Is It Normal

Jan 12, 2009

Lately my year old macbook has been getting very hot when I watch videos on Safari. If I pause the video it cools down fairly quickly but this never used to happen. I looked at the CPU usage using Activity Monitor while this was happening and Safari was consistently around 100. Also, when I am on the dashboard CPU usage of inoRT jumps to over 150%. This does not seem normal.

MacBook Pro :: Dim Screen With Overheating When Lid Closed?

Jul 11, 2009

I'm very new to Macs (4 days) and hope to get involved in video editing on a professional basis. I have matched my 13" macbook pro to a 23 inch widescreen monitor and wanted to inquire as the best way to keep the macbook pro ON, but also save on space. I have heard of 'Insomnia' which disables the sleep function on the mac and wanted to check if, by dimming my screen down to off (the minimum brightness the screen will go) and turning on 'insomnia' will that be enough to prevent the screen/unit from overheating?

OS X :: MacBook Pro With Snow Leopard - Overheating

Oct 3, 2009

It only happens when I am streaming movies but the other thing is my computer also seems slower now too. If I stream a movie for more than 10 min my computer gets real hot and disconnects me from the internet and I have to restart my computer in order for me to reconnect. I also called a mac specialist in my area, the apple store, and best buy and all of them said they haven't heard anyone complain about this? I just wanted to start another thread on a different forum to get the word out. [URL]. This is a major problem that needs attention.

MacBook Pro :: MBP 15" 2.8GHz Overheating?

Feb 28, 2010

I just took home a MBP from the local Apple Store.

Is it normal for the palm rest area, mainly the portion under the control/option/command button to turn warm? I have used many MBPs at my office, and they seem to be very cool.

It is a TAD uncomfortable to rest my wrist on it, unsure if it is common problem or if it is acceptable.

Currently just surfing, and emailing. Using 9400M.

MacBook Pro :: Its Overheating At Power Plug

May 4, 2012

I'm getting overheating at the point where power enters the computer (the little cylindrical device that plugs into the magnetized power port.) The transformer feels fine, as does the cable, but that cylindrical plug gets way two hot to touch. Other answers relating to this subject indicate that charging an almost exhausted battery while also using the computer will cause overheating in the transformer, but the transformer feels fine. It's that little cylindrical plug that collects an amazing and worrisome amount of heat.

MacBook :: Overheating And Loud Fan On 13"?

May 17, 2012

I've had my Macbook Since early 2008. But only in the last 8 Months my fan has become increasingly Noisy and Hot. I upgraded to Snow Leopard last year (I'm on Mac OS X 10.6.8 ) and it seems it became alot noisier after this. I originally only had 2gb Ram, but upgraded this week to 4gb ram thinking that would help. I've also gone and purchased an external hard drive and moved all my movies, photos, music etc onto this in an attempt to not only back up my files but hopefully alleviate some of my space on the mac. I've tried the Resetting SMC and also followed another apple step by step guide (??) and in my activitiy monitor nothing is even over 10% and i've been regularly checking for the last hour. I'm aware the fan is always running, but the noise is ridiculous. I've done so much research on this and i'm at a complete loss, I know there is only one fan in this version of macbook and it's definitely running as I hear it all the time.

MacBook, Mac OS X (10.6.8)
