I have seen this question answered before but can't find it in the archives. Almost immediately after starting to use the laptop the fan starts running and doesn't quit until you put it back to sleep or turn it off. Any ideas on why this is happening and is it harmful to the computer in the long run?
View 7 RepliesI have a late-2006 MacBook (2.0 GHz Core 2 Duo Merom) that has been serviced several times. It�s had the fan replaced twice: once in the summer of 2007 because it completely failed, and once in the summer of 2009 because it had been making clicking noises. The logic board was replaced last November because of some minor issues with the headphone jack, along with the LCD which had some gray dots starting to appear.
I�m not sure how long it�s been doing this, but the fan seems to be running way faster than would be normal. The fan never seems to run below 5000 RPM, and once the CPU warms up, it seems to run continuously at 6200 RPM (the maximum speed). smcFanControl (set to Default fan speed, the minimum) usually reads the temperature as being between 145 and 155 degrees Fahrenheit. I took the keyboard off yesterday to clean dust out of the fan, but it didn�t seem to do much. I�m pretty sure this isn�t a software issue, because the fan also seems to run a lot when the MacBook is booted into Windows 7, although I�m going to try booting it from the OS disc and an external hard drive just to be sure. I�ve tried resetting the SMC, and I�m pretty sure I tried resetting the PRAM a while ago. The only remaining thing I can think of is that when the repair tech replaced the logic board, he didn�t apply the thermal paste properly (the optical drive was replaced even though it was working when I sent my MacBook in, two hinge screws were overtightened, and the bezel was not installed properly).
Are there any other things that could be causing my MacBook to not cool properly? If booting from another copy of the OS doesn�t change the fan speeds, I�m thinking about taking the heatsink off this weekend and applying some Arctic Silver.
For no apparent reason, my iMac (27" mid 2010) has a very loud fan all of a sudden. PCU usage is not high.I already followed the instructions to reset my SMC... Nothing changed.I used compressed air to clean eveythingn I could... No change.

When I made the switch to the Mac world with a MacBook Pro, I needed to replace my old Microsoft Money for simple small business functions. I tried a number of Mac programs, and all were lacking. Fortora came close, but definitely no cigar. So I installed Windows 7 to permit me to run Quicken. Despite all the strong negative reviews, this program works well and is far ahead of all Mac financial software. Since I use Windows only for Quicken and for Audible Site, since iTunes does not play nice with my Sansa Clip.
I didn't want to divide up my 4 MB of RAM using virtualization software. So I use Boot Camp, and this solution works well for me. What was immediately obvious was that my Mac Book runs very hot when using Windows, where I do little more than use Quicken. So hot that I dare not set my machine on my lap. As soon as I reboot to the Mac OS, the machine cools down. My impression, although I have not really tested this, is that the battery also runs down faster on the Windows side.
MacBook Pro 2.16 Intel Core2Duo with 2 GB 667MHz SDRAM runs very quietly when being used. When left with lid closed overnight but still logged in, each AM the the fan is running loudly at high speed and the case is hot. As soon as I open it and it starts up, the fan quiets down and the case is cool in a few minutes. The temps range (when open and quiet) from 90-125 F for various components and the fan speeds are about 2000 RPM. Why should it run hot when closed and asleep.

Sometimes, when I have only Mail and Safari open and am just browsing emails, the fan starts to run full speed, and the internal temperature reaches 180. This often happens when the Mac is actually idle and only displaying the screen saver! The room I'm in is rarely over 75 when this occurs. I don't really have any intensive login services, just a GMail notifier and things like Suitcase and iTunes Manager.
View 8 Replies View RelatedMy ibook G4 turned itself off and when I tried to power it up the fan turns vigorously while the screen stays black. Thats it.
Prior to this I was doing some pretty heavy music importing and during that time the fan was going nuts (I then stopped importing)...also while it was charging it the past few nights the light on the connector would go out and it stopped charging while it was still plugged in. This was the first time it happened and it happened 2-3 times.
Like for most people my entire life is on that computer along with a very important document that I need to access ASAP. What could be the issue...not the logic board!
I have 4GB of RAM on my (aging) MacBook Pro and use a very useful app called Memory Clean to maximize the RAM from time to time.Â
Recently, my laptop has been getting slower and slower to the degree that even opening windows in Finder brings it an almost complete standstill. When I checked the RAM it had decreased to under 10MB.Â
What I've found is that I can run Memory Clean and the more I run it, the more is freed up and the quicker the laptop runs (up to 2GB+ being available). However, within minutes it is plummeting again and so I have to rerun Memory Clean. Suffice to say, the laptop as a whole seems to be struggling.Â
What can I do-and is this a hard drive failing issue or something else?

I am planning to purchase a macbook pro. I will be using it at home mostly but wanted the option of taking it out if I need to. The salesperson told me not to plug the laptop in more than two days at a time. He said it's better to use the battery even if it's at home.

This morning, when I got into work I restarted my Late-2010 MacBook Air (128 GB HD, 1.86 GHZ Core-2 Duo, OS X 10.7.3) while holding down the "option" button as I normally do to access bootcamp and load Windows 7 because I need to use Excel Macros during the work day. Â What was unusual, however, was that it immediately started beeping loudly when I held down the option button and continued to do so without ceasing. It beeped 3 times, stopped, beeped 3 times, stopped etc. Â
The fans started running pretty quickly and I held down the power button and it finally shut down. I restarted and held down the "option" key again, booted into Windows 7 fine, and have since rebooted into OS X as well without issue. It's the first time that I've heard this beeping except when I installed a firmware update a few weeks back. I've done a bit of research and it sounds like it's indicative of a RAM issue but want to see if anyone knows for sure. I think it's strange that it did it once but hasn't again despite numerous restarts and also strange that it happened immediately upon hitting the "option" key when the screen went dark, as I always do.Â

My macbook, version 10.5.8, started crashing today. There was an update for Adobe Flash Update that popped up earlier today (I think it wanted to install a debugger), I X'd it out because I was doing something else (bad mistake), and now Safari crashes continuously every time I log in. I've tried to download things to my laptop to fix the problem, but Safari crashes before the download can even get halfway through. I've even tried to find the flash update for earlier, but either I can't find it or Safari doesn't stay open long enough for the update to download. The strange thing is, this is only happening on one account on my laptop– the one where the Adobe Flash Update popped up on. The other account on my laptop has Safari working fine (but it's not the account I want to use). Â

Ever since I upgraded to Lion (and doubled my RAM) it seems like my 2009 Macbook's motor ( for lack of a better term)Â seems to run and run until I put it to sleep. Is it all coincidental? I make sure it is vented. Doesn't seem to make a difference. And of course my Apple Care just expired.

I have a Macbook Pro 13in. from I believe 2008. Last night I was watching Netflix, with no other applications open, and within 2 minutes my computer shut down. I thought it was due to the fact that my computer was believe 7% battery life, but because I had it plugged in, I tried to reboot. It turned on for a few seconds but then shut off again. I tried a few times more later through the evening, but nothing worked and the same thing happened. Throughout the night my Macbook would turn on by itself (with the start up noise) and then shut down by itself continuously. It would repeatedly do it 3-4 times, give it a break, then do it again. I have been able to log on twice fully to my personal log on page, but it shuts down after a few minutes. I have tried resetting the SMC, PRAM, etc, but nothing works. I'm hoping I just have a bad battery because I have used the same battery since I purchased the computer.
View 1 Replies View RelatedHi guys, I have a 2.26ghz Macbook and when i start it up the chime keeps repeating over and over again until i get sick of it and hold the power button to force shut it down, sometimes it will start up fine after that and boot right up and sometimes it keeps repeating again, then i just leave it for a few hours and try again and it will usually work. Also over the last day or so i've been getting a mixture of the repeating chime and the blank white screen with no apple logo and grey spiral. Other than this problem the computer is running flawlessly, does this sound like a hardware or software problem?
I've already tried reseting the PRAM and SMC, I've ran the hardware test which came up clean, checked the drive with disk utility and eventually reformatted the HDD and reinstalled Mac OSX but still no change. I'm not running any extraordinary software just google chrome, Skype etc. so that shouldn't have any thing to do with it.
When running a lot of different applications (OpenOffice, R64, Microsoft Office, iTunes, etc.) on my MacBook Pro (2.2 GHz Core i7, 8 GB RAM), Finder freezes continuously. Most of the time it'll restart quickly, or in the best cases, it will eventually start working again after a few minutes. This is extremely annoying as I use my computer for work and constantly have to wait in order to access files. I've tried deleting hidden files in directories among other things, but nothing seems to do wonder.

Since the day I got my MBP two months ago I have always had it hooked up to a small HP HD monitor via HDMI. The other day I tried hooking it up to my 32 inch HDTV and now I am experiencing a weird problem. The TV and the Mac recognize each other but the screen continues to flash/blink every second (almost like it is loosing conenction). I check the cords and everything is fine which I assumed because everything is fine when I'm connected to the HP monitor.

I have read of wireless router issues with MBPs. I have the 13in, 2.26, 2GB (upgraded to 4GB) MBP. When I first got my MBP, I was having to continuously disconnect and reconnect to my router. I assumed I was having the same problems as others on this board have noted. Soon after, however, my work laptop (PC) started having connection issues as well and I have to perform the same process on it. disconnect, reconnect via the laptop, and then everything will work fine for anywhere from 10 minutes to a few hours. (Note: on the MBP, things only work fine for 5 mins or so before I have to perform the action again). It seems as though the MBP is more sensitive to the router issues than my PC.
Nonetheless, I am planning to purchase a new wireless router, since mine clearly has issues and it seems to be getting progressively worse. My question: Is there a particular router that seems to work better with MacBook Pros than others? Any that you guys would specifically recommend? (I need it to still work fine with a PC, as well, because of my work laptop)
I have a users machine that the fans wont stop running at high speed Its a 2011 MBA 13" i5 128gb ssd I installed a few fan monitors and fan controllers, they all say the fan is at 0rpm. Apple is not my first language; but Im warming up?I have performed an SMC reset as well as the P&R? reset?  Both went through properly, the SMC i could see the power cord light change colors, and the other reset performed before the chime would make the chime, black screen, rebooted. Alot of what I read on this topic consists of the machines fans ramping up because they are being used, or if its a fluke the SMC will reset it. I havnt been able to find anything in regards to the computer reporting 0% and just running non stop.

Backstory: Sunday the updates window popped up so I let it run and reboot. Boot screen is stuck on the white screen with apple logo and spinning icon. None of the typical hotkeys were working like the Shift key to go to Safe Mode. I decided to resinstall Snow Leopard which went perfectly fine since I was able to boot off of the Install DVD. Everything seemed fine after the install and I had all of my previous programs and files.
It worked fine all day yesterday until I shut the lid to leave work. I got home, opened the lid and the spinning mouse icon was continuously spinning. I could move the mouse but couldn't click anything. I shut it down using the power button. Upon booting it up I did not hear the boot up sound but a white screen displayed and didn't do anything from there. I rebooted it again, inserted the Snow Leopard DVD to try and boot off of that and it won't even boot off of the DVD. None of the typical hotkeys work either, not even to eject the DVD. I do hear the DVD spinning up but it doesn't do anything; just a white screen.
I did reset the PRAM which forced it to reboot and I got the startup sound back but it still only shows a white screen. Any ideas? I forgot to purchase Apple Care last month before my 1 year warranty ran out so I'm 1.5 months out of that.
I might be using primarily Soundbooth and After Effects for some sweet projects for school, and for my future music recording career path (maybe Logic Studio Pro is better?) I got to use both a VERY LITTLE BIT on a PC. But how well do they work on the Unibody MBs? Either 2.0 or 2.4?
