MBP: Fans turning up to 6000rpm during loading battery

Hi there,
I have a Macbook Pro 3,1 and I have the following problem:
If I'm loading my battery, the fans of my MBP are turning up to 6000rpm. It is very loud!
When I bought my MBP, I had never such problems with loading the battery.
What's wrong with my Macbook Pro?
Thank you!

I have the exact same problem as you, my MacBook Pro's fans spin up to 6000rpm when plugged in and then calm down about an hour after in unplug it... this is very annoying since I am in class.
When at 6000rpm, my cpu is at 65C, and when my fans are not running as fast (+/- 2000rpm) the cpu temp is at 78C!
I don't think that this is very normal and I have read that it could be good to run a Extended Hardware Analysis, using your Disc 1 installation that came with your mpb.
This procedure is tricky because I did it last night and it reported a sensor malfunction on my mother board, and this was when I did the shorter version of the test, this morning I did the extended version and no problems were reported... I'm very confused!
I have read that quite a few people have similar problems and they all seemed to have brought their mbp's in to be serviced, I might do the same, and so should you.
Good luck!
Mathieu

Late 2009 MBP fans turning at 5600 rpm all the time, bluetooth unavailable and wont turn off

Hello,
I have a late 2009 MBP, about a week ago the fans started turning at around 5600 rpm constantly, they are very noisy. The bluetooth has also stopped working, the icon's drop down menu says that it's not available. In addition, the computer won't turn off, it restarts immediately after shutdown. I have reset the PRAM and SMC but with no luck, this has been annoying me greatly. Any help would be greatly appreciated.
Thank You

You've already done the two things that I would suggest (resetting the SMC being at the top of the list). Your fans may be failing - I had the same problem with one of my fans and it had to be replaced.
The problem is with your other situations - I would really suggest backing up your data and making a clean install of Lion to see if that rectifies your Bluetooth, shutdown, etc., problems (as the SMC reset didn't). If that fails then it's time to visit the Apple Store and have them run diagnostics. Just curious, though... does Bluetooth show up under your System Profile as being connected via the USB hub under Bluetooth USB Host Controller?
Call back,
Clinton

Mbp fans are coninously at 6000rpm.

hi
after encountering some HD faillures, i installed OS X 10.5 from scratch.
after that my fans spin continously at full speed, have done a smc & pram reset severall times, but that didn't work out well.
now i'm monitoring the temperature and my fans with smc fancontrol, while throttling the fans through terminal.
do you guys(or gals) know of any solution, i have searched the net but i didn't found any answers(other than the terminal thingy..).

Hi Baby Boomer,
Here is the information you mentioned in your reply.
Next thing is trying the firmware update thing.. hope it works
After i started this thread, i went to a franchise apple retailer. We don't have an apple store in holland(not that i know of..)
At the store they didn't know what to do, and suggested to call apple. Doing that tomorrow..
What they did mentioned was that it could be a logicboard problem instead(but isn't that what the firmware update is for?)
Guess i go back after the weekend to ask for those tests, which tests do exactly mean? (if calling apple don't bring a solution)

MBP randomly turns off while plugged in & on battery

my MBP now randomly shuts down, at any time, regardless of the state the computer is in (at least 5 times a day) i often then have trouble actually getting it to boot, as it will shut off 7-10 times before it actually gets to the password area

many more can be found on google.
the battery was replaced under the recall.
any ideas??
Thanks,
David

I've had the same problem quite a while but finally found out today something useful. When I installed the iStat Pro widget, I started to wonder why the left fan showed 0 rpm. Then I also realized, that I haven't heard the bit noisy fan in a long time.
The solution was easy. I opened the cover and using pressurized air cleaned all the dust off the fans and made sure the connectors were good. Now my MBP has been running 10 hours without any problems though yesterday only it shut down several times.
So if your warranty is expired, just do the same before letting anyone sell you a new logic board or anything.

Powermac G5 light go's on will not boot up,fan turns on

My powermac G5 DUAL 2.3GHZ PROCESSOR will not boot up light turns on then fan turns on. I replaced the battery cr2032 and it still does not work. Please help solve my problem. Thank you again in advance. The apple support communities is the best.
Carlos from NJ EMAIL--- [email protected]

Do you get a boot tone (chime) when you power up?
If it does, try a safe boot by powering with the shift key held down.
If it doesn't, you have a fundamental problem to deal with. Are any LEDs on the logic board illuminated after you power up?
If so, this might help: http://support.apple.com/kb/HT2652

MBP Fans speed up during minor operations

Hi everyone,
Something has happened to my MBP over the last few weeks. It always has been the case that whenever I have my MBP do a heavy operation (compressing HD video, for example) the fan kicks up to 6000rpm, as it should when all the computer's available resources are going to a heavy operation like that.
But now, I can just be browsing through a couple of different Firefox windows or have a few programs like Word or Excel open and the fan will kick up to 6000rpm again. And it won't quit unless I do something about it. I'll either have to close it up for a little while, or take it to the basement in my office where it's about as cool as a fridge. When I take it downstairs and set it on a cool surface, within about two minutes the fans have dropped back to 2000rpm.
Here are my readouts I get from when I have the MBP on my desk and it's up at 6000rpm versus after I've had it downstairs for a few minutes:
Before:
CPU: User 16% System 4% Nice: 0% Idle: 80%
Memory: Wired: 215MB Active: 538MB Inactive: 1.01GB Free: 1.25GB
Temps: HD Macintosh: 108F CPU A: 133F Enclosure Base: 99F GPU: 124F GPU Heatsink: 130F Heatsink A: 124F Heatsink B: 113F Mem Bank A1: 140F
Right Fan: 6001rpm
Left Fan: 5994rpm
After:
CPU: User 8% System 5% Nice: 0% Idle: 87%
Memory: Wired: 215MB Active: 539MB Inactive: 1.02GB Free: 1.25GB
Temps: HD Macintosh: 108F CPU A: 131F Enclosure Base: 97F GPU: 117F GPU Heatsink: 121F Heatsink A: 119F Heatsink B: 101F Mem Bank A1: 133F
Right Fan: 1994rpm
Left Fan: 2003rpm
And just now as I was writing this post, the numbers went back up to where they were before I brought down to the cool room. Any ideas?

That is always a problem--you need your Mac so you can't ship it off for repair because you can't do without it.
I think that Apple has some sort of a program where you pay an annual fee, and as one of the benefits, you can get a loaner if your Mac has to go off for repair. This may be something to consider.
Be sure and at least get a case number to document all the problems that are covered by your warranty, and be sure and send it off before the warranty expires. I still think the genius bar could run the AHT to see if you have a sensor problem or not. If you do, it is something that needs to be fixed at some point.
Good luck!

Ambient MBP fan sound.

Background: Have an old iBook G4 12”, the first G4 iBook. Had 4 (count them) MBP 15” machines, ended up getting a refund on the 4th instead of a return. Looking to try my MBP luck again after reading about the new motherboard in week 25+ machines. Typing on a POS Dell at the moment.
What I am interested in is the idol fan noise. On my iBook, I can't hear a thing. When the machine is on you just can't hear anything, it’s excellent. Under intense load you hear the fan turn on, and once it's done it's thing the fan turns itself off.
Each of my MBP's had the whine and other problems, so they were returned for those reasons. But every one had the fan on all the time; I could hear the fan constantly. It came on louder under load, but dropped back to its still ‘audible-not-iBook-silent’ state. Comparing the MBP no load fan sound to this Dell fan is laughable, I can’t complain. The MBP sound isn’t terribly loud… but it is there.
Is this how it's meant to be? If it is I can live with it, it doesn’t drive me insane like the whine and it's a much faster machine... but I just thought I’d check up
Cheers.
iBook G4 12 800Mhz... looking at my 5th MBP :/ Mac OS X (10.4.7)

I have one of the first MBP. Originally the fan was essentially silent most of the time. After one of the patches, I notice the left fan just a little, a very quite sound that I have to listen for to hear. On a few occasions I purposely taxed the machine and noticed that the fans are variable speed, slowing ramping up as the heat grew. They quieted right back down when appropriate. Compared to other brands that I have owned, the Apple is the quietest notebook I've had. I have no whine, either. There is mild case warping. My first battery died after 2 months. Other than that, the machine is fine. Apple support has been awesome.

T61 CPU/GPU 90°C during load, 70°C during idle, normal?

Hi!
I have a Thinkpad T61 with the following specs:
Intel Core 2 Duo T7300 @ 2.0 Ghz
2 GB RAM (2 x 1GB) DDR2 667Mhz
nVidia Quadro NVS 140M 128 MB
120 GB 5400 RPM HDD, Windows XP Pro.
It's about 6 months old, and recently I installed a temperature monitoring program on it and noticed quite high temps on both CPU and GPU. About 90 degrees Celsius during load and about 70 degrees during idle. I've opened up the computer (palmrest + keyboard only) and use compressed air to try to blow out dust from the cooling assembly. But there was hardly any dust at all. And the temps are still the same.
Is this normal? Anybody else have these kind of temps?
Thanks in advance

Solved!
Go to Solution.

I got my thinkpad back today. They changed the fan for me. Now, the results.
The CPU now idles around 50 and during load about 60°C, I'm happy.
But the GPU is still the same, about 70°C idling, reaching around 80°C during load.
Is this still normal? Although I just mentioned the CPU overheating to Lenovo Support, I thought the cooling system covered both...
I might just buy a cooling pad.

MBP fans & tilting

So tonight I wanted to see how much it takes to get the MBP fans running, as I've never, ever noticed them before. I wrote a Python script that uses 100% CPU, and ran it twice (once for each core). I started at 51C, and it quickly jumped up to 75C within 60 seconds of running the scripts. It got to 79C, and then I felt (but not heard) the fans come on. The only indication I had that they were running was the vibration they made. The temperature hovered around 73C.
But this is the interesting part. I lifted my MBP up so I could bring it closer to my ears. and all of a sudden I couldn't feel the fans anymore, and the temperature immediately spiked back up to 79C. When I leveled it out, the fans came back, and the temperature went down. If they turned off because the back vent was suddenly more open, why did the temperature spike? I can't think of anything.
Can anyone else confirm this, or am I just losing my mind?

They're treating you as such because to Apple it IS
well within specs. Some guy complained about his
computer going all the way 90 (almost boiling) and
apple said same crap and ur complaining w/ 79, thats
all.
Yeah, heat is bad and Apple's paste-happy techs could
be partly to blame but, it is still "within specs".
I wonder how wide those specs are...
I was ready to buy a new Macbook Pro but after reading about all these heat issues and an undeclocked GPU and whining sounds I've been having second thoughts. I did find this spec sheet http://www.intel.com/design/intarch/coreduo/coreduo_spec.htm on the Intel website which does state that the core duo will run from 0-100c.
That being said I still think that temperatures approaching 90c is still too close to the wrong end of the specification. Surely the hotter it runs it must affect performance/lifespan. Does anyone know if the new Macbook Pros (released with the Macbooks) have addressed these heat issues and if they are still underclocking the GPU? (and 0-100c, I'd like to see one running at 0c, maybe in a blizzard whilst trekking the arctic circle)

HP Envy M6, Fan Turn off after 2 seconds, No Display, Blank Screen with Light

Hi,
I have HP Envy M6 15" Laptop with Intel Core i5,
Few days ago, I get a problem with my laptop, below are the symptome when I push my laptop power button:
1) Screen backlight on but no display on screen
2) Fan turns on for 2 seconds, and then turn off
3) Power light stay on as long as I again push the power button again
4) Wifi light turn "Orange"
5) Harddrive, and DVD drive shows sign of power-on for the whole period, even I can eject the DVD tray...
But get no display on screen, even when I connect with external screen, and fan stays off.
Can i get any help from experts out there?
Thanks
Sohaib

@SohaibAfzal
Have you tried connecting an external monitor to your notebook, to see if there is a display?
Since your computer does not automatically shut down again until you press power again, it is possibly the display itself that is the problem.

MBP Suddenly Turns Itself Off With No Warning/OS 10.5.8

Recently my Early 2008 2.4 GhZ MBP running OS 10.5.8 has been shutting itself off without warning. Previously it would provide a warning when the battery hit 20% and then it would go to sleep at some point.
The Finder Menu Bar battery indicator shows around 23% or one hour of power remaining. Coconut Battery shows:
Original Capacity: 5600 mAh
Remaining: 3473 mAh
Load-Cycles: 90
Age: 23 months
This is a problem because data has been lost when this occurs. Any ideas about what may be happening? I still have around a year left on an extended AppleCare warranty...

The new battery hasn't been used long enough for me to tell; I only installed it last night.
My wife is the primary user of the affected MBP and she often uses it until it goes to sleep due to low power, so I anticipate having an answer in a week or two...
Can the fact that my wife often ran down the old battery to such a low level have contributed to the development of this problem? What I find curious is that previously the MBP would simply go to sleep when the battery power got too low. And that quite a few MBP users are suddenly complaining about their Macs turning-off by themselves even when using new batteries...

When turning on my imac, it loads to a blue screen with a turning wheel and never gets passed that. I have tried booting to safe mode and it still doens't work.

When turning on my imac, it loads to a blue screen with a spinning wheel. It never gets passed that screen. I have tried power up to safe mode and it still doesn't work. I have music files saved on the computer and I don't want to lose any of my files. Can someone help me?

Zap the PRAM and Reset the SMC, and see if that fixes it. BTW. detailed computer and OS info goes a long way to solving problems.

Error during loading of transaction data: An RFC call-up triggered the ...

Dear Sirs,
during loading of master data from a 4.6C SAP system to BI 7.0 SP9 I get the following error during processing (data packet).
<i>"An RFC call-up triggered the exception (ID: RSAR NO: 503) "</i>
The strange thing with this error is that it emerged today, after successfully loading master data and a subset of transaction data yesterday from same source system.
Has anyone else come across this error, and can tell us where we should look for a possible solution? (or a better error explaination).
The RFC connections works fine when testing in SM59, and was functioning yesterday. No relevant dumps in either system.

Hi folks,
I am also interested in this error.
Thanks.

HT4623 How to turn-off tap display during passcode entry

I recently bought Iphone 4s. I like the phone as such but one thing that I want to change is tap display while entering the passcode on lock screen. I don't want to see which keys I am entering as this can put my phone on risk as anyone close to me can see what keys I had pressed to unlock the phone.
Please help to let me know "How to turn-off tap display during passcode entry" on locked screen.
Thanks for the answers and suggestion.

This cannot be done. You should simply hide the display from others' view.
iPhone 5S allows you to use your fingerprint instead of the passcode.
