MBP won't wake, is REALLY HOT, fans going full blast

This morning I made sure when I closed the lid on my MacBook Pro, that it went to sleep (pulsing sleep light). I found that this doesn't always happen right away, unlike the old Powerbooks. I then put it into my laptop bag, confident that it was fully hibernating.
When I arrived at work and pulled the MBP out of the bag, the sleep light was solid white, the laptop was really hot on all sides, and the fans were running hard. I opened the lid and there was no display, although I knew it wasn't sleeping because I could hit "caps lock" and it would toggle on/off. Apparently it had awaked while in my bag for some reason. The only way I could regain control was to hold down the power button and start from a "cold" boot. When I logged back in I could not find anything odd in /var/log/system.log during the time before the reboot.
My Energy Saver settings for "battery" mode are set to "Better Battery Life" so theoretically nothing should be able to externally wake the MBP. Bluetooth is Off. I have no idea then what caused it to wake up and flip out. This is the second time this has happened and I've been wary of its sleep behavior. Is there an updated SMC firmware for the 17" model yet?
This is really worrying because I could have left it in my bag for a lot longer and who knows, maybe it would have caught fire!

It happened again. I did a hard shutdown to keep it from really geting hot. After the boot, I checked the system.log. At the time which I suspect the interrupted sleep occured I saw this, which seemed to repeat a few times:

Can't wake up my iMac in the morning and fans going full blast

Several times in the morning, after leaving my iMac on all night, I've found the machine asleep and the fans going full blast !?!
This in a cool 68 degrees room.
I then had to turn the iMac off manually and restart. I had a failed power supply replaced in April and am covered under the Apple care program (thank goodness !!!).
Could this be the logic board overheating now ?
Thanks for your help- Jim Vaughn

Hello Jm - it could well be another thermal problem, take a look at your Console logs and see if anything jumps out at you.
Since you do have Apple care (wise man) I suggest you call them and have them deal with the problem.

G5 won't wake up from sleep & fans go to high speed ???

G5 won't wake up from sleep & fans will go to high speed within a few minutes of it going to sleep. Whether I put it to sleep or it goes to sleep on it's own per my preferences in energy saver. I have to manually shut it down by holding the power button in. I ran the system hardware dvd and results were good. I have repaired permissions, reset the PRAM.
Any ideas?

Fans blowing full blast during sleep

My MacBook Pro (15", 1.83GHz) will turn its fan on +full blast+ whenever it sleeps. This happens immediately, and regardless of whether the lid is closed or not. The computer goes to sleep fine from the Apple menu, and the indicator light pulses (i.e., I think it is really asleep). I've let it go all night long, and the fan never seems to stop. I can get good temperature readings from all the sensors, and the RPMs on both fans look reasonable while the computer is awake. They also modulate in a normal range during use. I haven't had any other trouble with it.
Originally, this computer was salvaged. It wouldn't turn on or charge. I replaced the left I/O board (containing the DC board), and it works fine now. I can't think of what would be causing this, but I'm open to consider that I didn't plug something in correctly as I was reassembling the laptop. I also don't know what caused the original failure of the left I/O board... so I'm not ruling out weird water damage or something.
Any ideas are appreciated. Thanks.

Hi Bill. It is worth bearing in mind that the "default" on most Macs if the OS thermal control routines can't be accessed, or if data from a sensor is not available, for example, is to send the fans up to maximum revs.
Usually when people experience the "full fans during sleep" situation it is because the system is actually "crashing" when sleep is attempted. In such situations , of course, the computer fails to actually "wake up" when asked to and has to be force shutdown! I gather this isn't the case with yours? It wakes up normally and the fans return to normal speed when it wakes?
If the OS isn't loaded (or isn't getting the right readings) , of course, the fans go into hyperdrive anyway (hence the flat out activity when running the Apple Hardware test and the like)
It sounds almost as if the computer is losing effective "Operating System control" and going into "hyperfan" mode accordingly when sleep is activated, but not actually crashing, and then recovering control on waking.
I presume you have tried things like wiping the drive and re-installing the OS from scratch and a PRAM reset as well as the SMC reset already mentioned?
Cheers
Rod

My MacBook Air 13' (2013) will occasionally start the fan at full blast, not connect to any wifi or detect any wifi, and will remove the battery icon from my menu bad as well as tell me there is no battery connected. How do I fix this?

My MacBook Air 13' (2013) will occasionally start the fan at full blast, not connect to any wifi or detect any wifi, and will remove the battery icon from my menu bad as well as tell me there is no battery connected. How do I fix this? I have restarted my computer multiple times, **** it down, and ran a diagnostic test to tell me nothing is wrong and my computer is not running any applications. There is no reason for the fan to be on full blast! when I try to set the option to show my battery icon in the menu bar, it will automatically uncheck. How do I fix all of this?

Have you tried SMC and PRAM resets?

GeForce 8800 GT Fan running full blast

Hey there folks,
I have a Mac Pro (early 2008, MacPro 3,1) with the OEM Nvidia GeForce 8800 GT graphics card.
Last night when I got home from work I booted up the machine and the fan on the 8800 came on full blast, it has always done this for 3-4 seconds on boot and would then spin down again. The thing is this time it never spun down, it kept going full blast and has ever since. The card is not under heavy load and is cool to the touch. The fan keeps going full speed so long as the machine is on, regardless of activity. Only when it goes to sleep or is shut down does the fan stop.
I've tried resetting the PRAM, resetting the SMC, and even ran Apple Hardware Test and it returned no errors. I have iStat Menus installed but I don't believe it is capable of showing feedback on the card. I haven't been able to find much online about this issue and there are apparently no Mac versions of Nvidia's control and monitoring software for their cards.
I took it into the local Apple store today and the Genius Bar almost immediately told me its a flat-out replacement issue. The machine is out of coverage so ordering a new copy of the same card is expensive ($380). I've looked into other, newer cards like the ATI 5770 or 5870 through Other World Computing and they seem like good options.
Has anyone else come across this problem or know of a workable solution?

I replaced the card. At first I took it to the Apple Store but the person there said its basically just a somewhat common hardware failure on the card. Not much to do but repair or replace it.
Rather than spend the time and money to have them diagnose it further just to tell me the same thing I replaced it outright with a card from Other World Computing; the ATI Radeon HD 5770. IT was a good alternative for my machine which, due to it's hardware configuration, has only a few to pick from as viable replacements. It's been working fine so far, no complaints. Just be aware it is a BEAST of a card and puts out a lot of heat.

HT3964 I followed the steps here, but I still cannot get my iMac to stop runnin the fan at full blast. What now?

I followed the steps here to reset the SMC, but I still cannot get my iMac to stop runnin the fan at full blast. What now?

Ensure you are using the SMC reset for an Intel iMac. Sometimes it take several tries back to back for the SMC reset to work. I've included a link to the correct instructions for an Intel iMac (just in case) , click https://discussions.apple.com/docs/DOC-3603.
If you still have issues then run Apple Hardware Test in Extended Mode at least 3x, it's also possible you may have a damaged fan or fan sensor.

Powermac G5 Dual 2.0 thermal calibration issue - Fans on full blast!

Hello, I need to do thermal calibration on powermac G5 dual 2.0. Does anyone know where to get ASD dual 2.5.8 discs? I'm afraid to run the computer with fans on full blast. Any help would be greatly appreciated!

Hi, ASD has never been available to the public, but even if somebody had any clues or other suggestions, you & Apple are the only ones that can see your eMail in your profile.

Random Overheating/Fans Running Full Blast

Hi there,
Ever since I received my Early 2008 Mac Pro a couple of months ago, it would randomly begin blowing the fans at full blast and continue to do so no matter which OS I boot to, Mac OS X, Windows, or even Linux discs. iStat Pro reads that my Northbridge is running at 249º F, which is completely ridiculous, since all of the internal components to the machine are running very cool. This Northbridge sensor is appearing to throw the fans into overdrive. It sounds like I'm working next to a vacuum cleaner. It's very loud and irritating to work next to.
Unfortunately for me, I don't live near an Apple store, or have the means to get to one. Apple also will not let me send in my machine. About a month ago I had the chance to drop my machine off at an Apple store, but the geniuses were very confused about the problem. 2 Weeks later I received a phone call explaining that my problem was fixed. They never explained to me how the problem was fixed. I had a friend drive out to the Apple store and pick up my machine for me, but when I turned it back on, it still ran full blast. Nothing was different.
I came back from work one day and to my surprise the machine was completely silent. It has been randomly going from full blast fan speed to normal fan speed ever since, fixing itself every few days. I have 0% CPU usage at all times, yet the machine thinks it's overheating.
So now I ask you, Apple Discussions Board members, what can I do to resolve this annoyance? I have:
Reset PRAM
Reinstalled Mac OS X
Unplugged the computer for days on end
Swapped Hard Drives
Taken RAM out
Tried SMCFanControl
Taken out that little CR2032 battery on the mainboard
And no luck. Help is appreciated!

Yesterday I popped in my disc and did an Apple Hardware Test. It passed with flying colors after hanging up and appearing frozen for 10 minutes. Found that little button behind riser A and pushed it for 5 seconds, rebooted a few times, unfortunately it did not work.
Also where is the Apple Hardware Monitor? Are you sure you don't mean Activity monitor? I couldn't find where the temperature/fan readings are in Activity Monitor.
The fans turned off, however, today when my computer woke up from sleep mode. They were off for about ten minutes when all of a sudden the fans kicked on full blast. This was strange because the computer would usually gradually increase over a 15 second period... not immediately. So now it's still stuck here, making noise :\

MBP won't wake up

My MBP goes to sleep after setting for a few minutes and it won't wake up after that. Although, if I manually put the computer into sleep it will wake up. Of course I'm waking it back up only a couple of minutes afterwards. Basically I end up shutting it down and turning it back on to get going again. Any ideas? Thanks in advance to any and all suggestions.

Here's something you can try. No guarantee:
In particular, some users are finding success with a workaround we've suggested for various wake-from-seep and related issues -- deletion of the following files:
Home/Library/Preferences/com.apple.systemuiserver.plist
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
This workaround may need to be repeated from time to time as these files can become corrupt with some frequency.
Also, check the console log using the Console application in the Utilities folder. Look for entries right around the time when you are trying to wake up the computer. See if there are any entries that may provide a clue to the problem.

MBP won't wake up from sleep

My Macbook Pro won't wake from sleep. Does not matter how it goes to sleep. Screen stays black after going to sleep. I have to resort to depressing the power button for a long minute to get it to shut down then push power again to reboot.
Started when Mobile me came in, but don't think that is the cause.

Try resetting the SMC. Here's the instructions

Sleep - won't wake up, and now randomly goes off to sleep

Since the recent security update, my 1.67 G4 Powerbook has been experiencing problems with sleep. Sometimes it won't wake from sleep, forcing me to hard reboot or pull all power out, and now it's randomly falling into sleep when it shouldn't.
The issue is progressive - it will sleep, then I wake it, then it goes down again 2-3 minutes later, wake, then seconds, wake, then deep somnambulistic slumber.
I read in Macintouch that there was a fix recently for Intel MacBooks and sleep, but some of us in the PPC world are feeling it's effect.
I've reset the pram several times, and on one occasion the fan spun up very loudly on boot, then quieted down after 5 seconds. Might be nothing.
Another factor is the battery - pull the battery and the system behaves better. I wonder if there's a lowered thermal limit that, when the battery is charging, causes the system to shut to sleep...?
Anyone else having this problem? I'm ready to slip back to 10.4.9 to see if that makes it more stable -- this happens several time a day now.

For other who may be watching this...
The laptop did keep shutting down into sleep, but - following from a tip from another site - I began trying three things: One or all seem to have resolved the issue:
* Repair permissions - often and always. Something does get munged and I'd be interested to see if anyone else has the same files affected:

* I stopped zapping the PRAM when it went to sleep or wouldn't stay awake on boot - I just booted from DVD instead and, lo and behold, the thermal errors didn't occur under the DVD. Fixed permissions and a reboot it often worked fine for hours.
* Running it alternatively from either battery or from mains. Initially under the battery, it would sleep at 70-60%, then - after a few days of being shut down instead of slept - it began running down to 0. I'd have to plug the unit in and charge it whilst off, but now -- after a week of this - everythings back to normal.
Ultimately, I'm sure this software. Something is up - and slowly, if you're patient, you can bring your system back without buying a new case or motherboard.

G5 won't start, fan going full-on

Hi All -
I came into the office yesterday to discover that my G5's fan was going full-on, with a blank screen. I couldn't get it to wake up, so I shut it off, then restarted it. The machine powers up fairly silently (no start up tone), but I get nothing on the screen. The fan comes on eventually, and gets louder and louder.
I tried doing a PRAM reset, but nothing happens.
Any ideas?
I haven't tried the power supply check yet, but will unless someone has a better idea.
Thanks!

I am having an identical problem with my 2.5DP G5. Since upgrading to 10.5.3 the mac wouldn't boot. Just black screen as above. I reset by taking out power plug for some time and then replacing and managed to boot into my external cloned (Superduper) drive (thank god I have one). The mac still would not boot from my internal start up drive. I erase zeroed that drive and copied back to it from my cloned drive. The mac still would not boot from it. So I guessed that I basically had a drive failure and bought a new internal 500Gb drive. I have re-copied the system and all my data onto that drive via the Superduper program so system is blessed.
Tried to boot holding the alt key down - saw the drives and my new drive was highlighted but screen froze at that state - so had to shut down using the power button.
Now the mac will not start at all.
I hear one chime (trying to reset PRAM will not work - only one chime) and that's it - nothing - just a blank black screen. Fans spinning like mad, but no start up noises - no drive activity.
Taking out the power lead trick has also ceased to work.
I am desperate! Anyone got any ideas?
Thanks

Hard Drive failed- new one installed - won't boot - fans going full

I have a mac mini one of the earlier intels. I came home and the fans were going full on, I turned it off and treid to restart.. and got the empty folder. So I guessed it was the hard drive. Took it out and tested it on my enclosure - with disk utility - buggered.
So I installed another hard drive after I had installed the OS. As soon as I connected the powere cord the fans still going full on.
I still get the missing folder symbol.
I tried booting off a usb connected hard drive and it starts up.
Any ideas?
I am guessing the hard drive has caused some other issue, can I do an internal reset?
Also, when I boot off the external hard drive and open disk utlity - I can see the other internel hard drive??
But it wont boot from it?
Appreciate any ideas... I have run out!!
Thanks in advance
Ross

AHA, just fan issue?
Tukaine
Sep 23, 2012 10:59 PM
Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
Instead of HDDFan Control, get the free SSDFan Control

Sleeping G5 often makes fans run full blast and machine unresponsive

the only thing new lately is that I installed Leopard 10.5.3 on my dual 2.0 GHz G5 tower.
I usually sleep my machine all the time
now it's a crapshoot whenever I sleep it whether or not it will go to sleep normally, or freeze in a state of screenless unresponsiveness with the fans running on full blast with no way to stop except a hard shut down or power kill
other than this the machine is literally working just fine. Never interferes with my work.
I don't know if this is 10.5.3 related or not, but I do wonder.
I started up from an applecare disc and did a full diagnostic and everything checked out
I guess I'll have to test Tiger sometime again but that'll be a pain because I'm already addicted to Leopard
I just hope this old faithful tower isn't going dead on me. and I wish there was some official word if this was just a 10.5 thingy

I believe I have solved this problem for now.
I opened up my G5 and used compressed air to blow out all the months of dust buildup in the machine.
I re-seated every single removable component inside (RAM, PCI cards, graphics card, etc)
I also pushed the PMU reset button once and then put the machine back together.
I proceeded to sleep it and wake it up about 5 times in a row, and it didn't exhibit the blowing fans problem and the light was "snoring" as it normally should in sleep mode.
A few days later, the machine hung up after being put to sleep AGAIN with the fans kicking up and the light on my cinema display staying one dim level without the "snoring."
This time I disconnected my Belkin USB hub and I have not seen the problem resurface since.
The interesting thing is that cleaning out the machine and resetting the PMU sure seemed to help.
So maybe it was a combination of things that were the culprits.
I also wonder if I can ever use this perfectly good and only 1 year old Belkin USB 2.0 hub ever again.
My father uses the same model on 10.5.4 as well on his MacPro without any problems. I am on a G5.
I wonder if there's a firmware on the Belkin USB hub that could be in need of upgrading or if I simply cannot use this hub w/ this computer anymore.
(luckily I don't need it urgently right now)
I will report back if the problem happens again, but for now, since the computer has been sleeping totally fine for days now since removing the USB hub, I am marking this question as answered and hope that this info can help other people.
If anyone has anything to add to this thread or knows about the specifics I've discussed above, please feel free to respond more.
Thank you
