Powerbook is too hot

The fan runs constantly on my powerbook G4, and it's always running very hot. Seems to have started shortly after a repair some months ago - logic board and case were replaced. Any suggestions? Sometimes I even think there's a burning smell.
Thanks.

Hi Tibrooklyn,
Please check whether your Powerbook is running in high performance mode constantly. Do this by going to the energy saver tab in system preferences. There you should set your performance level to automatic. This way your Powerbook will run cooler and will drain less battery power.
Otherwise, elevate your laptop to allow fresh air to help natural convection of hot air at the bottom of your Powerbook. Place a book at the back of the unit and let it sit at an angle. You could also invest in a griffin icurve or ilap, both of these assist in cooling the machine by raising it off the ground.
If however the problems remain, and if for example the fans turn on full right after powering on the machine in a cold state, I suggest you take the unit to your nearest AASP and have them check it out.
Good luck!

My PB runbs always too hot: it burn my lap. & battery runs only 1 hour.

Hi.
As the subject, my PB runs too hot.
I found sombody asked the same question and downloaded software to measure temprature.
Battery: 35 C
Power Supply Bottomside: 55.8
Processor Bottomside: 62.5
Processor/Controller Bottomside: 64
SmartDisk Fujitsu .... 48
Trackpad: 40
I'm not running any games. don't know why so hot.
And my battery last shorter than before: I was surprised it lasted only 1 hour or so last time I used without AC.
Anybody any suggestion?

Hi Shiho,
It sounds like your Powerbook is stuck in turbo mode Have a look at the energy saver tab in System Preferences. Make sure that the performance settings are set to automatic. This will make sure that your processor scales to your performance needs and isn't at 100% the entire time. Doing so would cause it to heat up significantly and as a result drain the battery much faster.
Additionally, make sure that there is sufficient air flow at the bottom of the powerbook. If necessary, prop the back up by placing a book under it, or have a look at purchasing a Grffin iCurve or iLap to elevate the laptop. The other temperatures you posted are normal and within spec, and the processor temps look normal for one which is under a bit of a load.
Good luck!

Powerbook G4 runs hot after OS X upgrade

I have a powerbookG4 that had 10.3.7. I upgraded today to 10.3.9 and upgraded iTunes from 4 to 6. (looking at the iPod video requirements) Now I'm noticing that it seems to run much hotter. I was on the internet, using AirPort (as usual) but the fan seemed to be running much faster and the bottom of the computer was almost too hot to touch. Plus, I also noticed in this form, that the computer automatically filled in the OS X form with 10.3.7, tho' I have verified in the 'about this apple' page that it now has 10.3.9.
Any suggetions? I wouldn't think running hot would be good for it, and if I want to use it on battery power, would use more power for the higher speed fan. (I did notice tho' that when I turned off AirPort for a few minutes and turned it back on that it's slowed the fan down some, and seems to be cooler, even after turning AirPort back on. Interesting.)

Welcome to Apple Discussions!
It sounds like you do may not be using the right discs. If you want to install Leopard, you will need the retail DVD--black with the purple aurora. If you want to install the original OS (Panther?), you need the exact install discs for the PowerBook. If you don't have these, you can call Apple with the serial number and get a replacement set for a fee.
Any other gray machine specific discs will simply not work. These are optimized for the computer they were shipped with.
The ?/Mac face just reflects the fact that the drive you erased is empty and there is no OS on it.
The idea of erasing and reinstalling the system software is basically a good idea. It just sounds like you are trying to use the wrong discs and will need to try to acquire the right ones.
Good luck!

Too hot to touch

My PowerBook often gets too hot to touch on the bottom. Is that because of a faulty battery? My batteries' serial numbers don't match those of the recall.

You might be interested in reading this thread:
http://discussions.apple.com/thread.jspa?threadID=602676&tstart=0
It's possible the heat is coming from something other than the battery. 3rd party RAM or defective RAM will commonly cause overheating problems. Try to figure out exactly where the heat is on the bottom and run the diagnostics suggested in the other thread.

OK, retracting my recommendation--this thing is too HOT!!!

IS anyone getting a refund for the heat issue?
I raved about this MacBook on here before but whoa did I speak too soon. This thing is so hot--wayyyyy hotter than my rev. A 12" powerbook. I mean forget using it when the power adapter is plugged in.
I don't just mean on your lap...I mean for prolonged typing, even when it's sitting on a desk.
I thought the main reason for the Intel switch was because the faster PowerPC chips were too hot in a laptop. But this Intel chip is scorching! Unbelievably hot!

your macbook is probably defective if it runs so hot that you cant even type on it! mine usually isnt too hot. i think idle its around 50s and when i start web surfing and doing other things it goes up to around 60s to 70s. normally, it gets warm on the back left side, but not so hot that it would burn me.
today however, when i was installing windows xp and ms office through parallels, and burning a lot of discs, i noticed that the back left got MUCH hotter than the normal "warm". it was so hot that i could barely hold it for a few seconds before i had to set it back down. whats odd is that coreduotemp only registered a temperature of around 69-72 degrees. i guess all the heat of the processor was being pushed out? i dunno...
i think im going to take mine back to return it and wait until apple deals with these issues. so the problems with my mac so far:
1) buzzing/whining power brick (on the brick and on the connection to the macbook)
2) extreme heat when doing optical drive intensive tasks
3) the moo sound
dont get me wrong, i love this machine and parallels is very cool with virtue desktops, but i just really dont want to be bothered by the moo/while/buzz/heat when im all alone in my tiny apartment in japan for a year where i probably cant even explain my situation to/understand the genius at the store in japan!
i hope you are still within the 14day exchange/return period so you can take yours in too!

Too Hot? My Fan Kicks On All The Time

In the last few months I've noticed my fan will kick on a lot more than it used to - typically when watching YouTube or Google videos, or using Photoshop - things which I assume require more resources.
Is something getting too hot in there?
Here are some temperatures:
Power Supply Bottomside: 141.3 F
Processor Bottomside: 128.7 F
Processor/Controller Bottomside: 141.8 F
I don't know how hot it's supposed to be in there, but that seems pretty warm.
Powerbook G4 (15-inch Aluminum) Mac OS X (10.4.7) 1.25 GB DDR SDRAM

I have a very similar problem. My G4 has been running great since I picked it up in January. But, in the last couple days my fan has been running real loud and the machine in general has been hot. Today was watching some youtube and my machine started to freeze up all togeather (a problem I've never had before) as the fan started sound extra loud. As I tried to power down my machine the fan started to make a more grinding type of sound and cause my whole laptop to vibrate. I just really want to know the best coarse of action here. Should I take my mahine to my mac people and have them replace the fan? Is this a common problem? What is this a cronic problem that is a symtom of somthing more ominoius?
Thanks for you're help!!!

Does the iMac G5 get too hot?

Greetings to all.
I would like to start a thread about the iMac G5 and heat. I found a few old threads, but I would like to bring that topic up again.
I have a 1st Generation iMac G5 (purchased end November 2004). For the second time since November 2004, it was defective and the Logicboard was replaced (so my Apple Dealer told me).
First time, in November 2005, the screen went pink. Second time, earlier this month, my Mac didn't boot anymore.
The full amount for the repair (including shipping to Apple (Belgium), work hours, etc.) was over 500.00 euro (about 700 USD for you, Americans).
I believe that the iMac G5 (at least: my 1st Gen one) is simply getting too warm.
The day before, I installed "Hardware Monitor". It gave the following (average) temperatures:
CPU: 60.6 - 63.8° Celsius (141-164° F)
HD: 57.5° C (135.5° F)
It is my opinion that the (my) iMac is getting too hot to be "healthy". I have 2 PC's, in which I installed extra fans (at the back and at the side). One of these, with an Athlon64 3000+ (1.8 GHz) and a 120 Gb Seagate Barracuda gives (average) temperatures for the:
CPU: 36.5° C (97.5° F)
HD: 26° C (78.5° F)
My second PC, an old (modded) HP Vectra, with an Intel P4 at 1.6 GHz and a 80 Gb Seagate Barracuda, gives as average temperature (HD only):
HD: 37° C (98° F)
It may not be correct to compare my iMac with PC's - but harddisks are harddisks, wheather it is a Western Digital (250 HD in my Mac) or a Seagate (PC HD's), and it is only logical that a(n average) HD temperature of 57 degrees Celsius (128° F) in the long term can not be healthy, while the harddisks of my PC's are a lot, lot cooler.
The PPC, too, gets much hotter than my Athlon CPU (and the P4 most likely too).
Therefor: is my suspicion correct that the/my iMac G5 in general is getting too hot for its own good? Even though it may be summer here (Belgium), I still find such a difference in heat values between my iMac and my PC's not "right".
Both the times that my iMac was defective, the Logicboard was replaced.
Is it possible that in both cases heat is the problem (directly or indirectly) of the defects of my iMac?
Basically we have a desktop computer constructed like a laptop, with all the hardware stuffed together in a very tight space. Why did they not keep the heat issue more in mind, when the iMac G5 was designed?
I believe that the heat is a very negative factor in the/my iMac G5. If I will have to pay such a small fortune, every time my Mac breaks down, being a Mac owner will become quite expensive.

Your Mac should have been repaired under the Apple power supply or video and power issues as long as your serial numbers were covered.
As far as normal operating temps are concerned, my Rev A is at this moment, running at CPU T-Diode 144∘and my Hard Drive is at 128∘so your temperatures seem well within normal ranges.
Yes, the machines tend to run a bit hot, but as long as the ambient temperature is not too high, they are fine. The failures were originally cause by a bad batch of capacitors but since those have mostly been replaced, the machines are much more reliable.
Some people train a small fan on the back of the computer to keep it cool, that may help you.

Droid Razr - too hot to touch

Having several issues with my Droid RAZR, purchased in June 2012. Current Android Version 4.1.2, Build Nbr 9.8.20-72....
Main issues are:
Battery life - stays plugged in all day & takes about an hour to go from 100% battery to about 65% battery. It's under 50% at 2 hours after being unplugged & is around 20% within 3 hrs.
Overheating is a problem. When not in use (and simply in a shirt pocket) it gets to the point of being uncomfortably hot. Temp in a battery app is between 42-45 C. If I use it for streaming audio, it gets too hot to hold. Heat is also up during any phone activity at all.
Drops in & out of 4G/3G constantly & is much more apt to drop that coverage down to 1x than ever before.
Also notice that the GPS flashes in & out more often recently than before.
Not sure exactly when the update to JellyBean was rolled out to me, but I have had more of these issues in the last 90 days than I did prior to that. I know that within the last 30 days other Verizon users with Droids have told me about abnormal power consumption on virtually all apps on their phone.
Using Advanced Task Killer v1.9.7 & have it set to autokill = crazy and interval = when screen off. Apps set to ignore are Gmail, a Craigslist app, Weather and Calendar. Everything else I have set to kill. Even with those apps, it is still warm to the touch.
Nothing I've done thus far has seemed to help curb the unusual power consumption on my Razr. I've cleared the cache on it several times, and it seems to have curbed the constant heat issue, but not the spikes in temperature that went unnoticed before.
I don't want to do a factory reset on it if I can avoid it, but would if it were the only resort.
Any ideas what else to try?

To answer your questions:
1. First thing Get rid of the Task Killer that can for sure cause the Heating as the ( Task Killer ) is constantly fight the Apps,
It is now uninstalled. I had installed it when I noticed that the Android OS was using a disproportionate amount of the system resources (over 50%).
2. try running the phone in Safe Mode you could have some apps causing the issue as well
I will give this a try. Most apps I notice take 3% or under of power consumption. The big ones are screen (30 second timeout), Android OS (as of now, they are about 70% of the power consumption) and Wi-Fi (at home). Android System takes only slightly more than the most heavy power consuming app.
Outside of the task killer, I had only installed updates to apps over the last month or so. I just booted it into Safe Mode & it got noticeably hot in the center after about 5 minutes.
3. And have you done a System Cache Clear in say the last couple of Months if not i would definitely try that
Yes, several times in the last week or so (Power off, then Vol + and Vol - and Power ), select Recovery,then select wipe cache partition & then reboot).
4. with a follow up of a Factory Reset
I had wanted to avoid doing that unless as an absolute last resort, since I have so many pictures, files, and other things saved on the phone.
and your last question:
5. And one other thing i like to ask are you using the Charger that came with the phone or Charging it Via a Computer if by computer Switch to the charger that came with it in the Box..
Yes (at home). In the vehicle, I am using a charger I purchased from Verizon when I got this phone. At work, I use an AC Charger that was also purchased from Verizon.
Thanks for the help. I will let you know if Safe Mode makes any difference.

Macbook pro 13" late 2011 too hot

I've been using my macbook for about 4 years in the same way with the same applications but recently I've noticed that it reaches very easily an high temperature and, consequently the fan works very hard draining my battery.
Analysing Istat pro I noticed that the temperature reaches 93° degree and more but looking up the processes it doesn't seem there is something wrong.
What do you suggest me? should I try to clean up the fans?
2 years ago I mounted the Crucial RAM update together with the 512gb ssd.
Thank you very much

Look at Activity Monitor set to ALL PROCESSES and CPU to display values from high to low. Are there applications using a lot of resources?
https://support.apple.com/en-us/HT203184
93°c is not too hot if the CPU/GPU are being heavily taxed.
In what condition is your battery? It is not unusual to have to replace a 4 year old battery. They do not last forever.
Open the MBP and inspect the insides. If there is dust and debris, clean it out.
Ciao.

Mac Mini too hot?

I would like to know if these readings are considered "too hot" for a mac mini (current gen):
HD: 42 C
CPU : ~55 C
Ambient: 40 C
Temperature readings are from iStat Nano, and the current outside temperature is about 90F (unfortunately, no air conditioning or fans in the room).
The reason I'm worried is because the mini feels very hot to the touch, and I don't even hear the fans inside running even though I'm sitting less than 3 feet away from it. The current fan speed is 1791rpm.
Thanks,
Jonathan

If it makes you feel any better my unibody mini runs similarly hot, and yes, mine too is hot to the touch (but far from being so hot I need to take my hand off it). Interestingly but not surprisingly, the side that the power supply is on feels noticeably hotter than the other size.
I think this is normal and expected as I previously compared it to the hot bottom of a MacBook Pro which makes perfect sense considering the aluminum unibody design and MacBook Pro parts inside + the internal power supply. I sometimes think the aluminum unibody design was intentional to double as a large heat sink. The ventilation where my mini rests probably doesn't provide the best air flow as it sits on a home-theatre style shelving system which is complete closed at the back with the exception of a small hole to run cables through. Actually, my generation one G4 mini in the same location would run so hot at times it would force the system to sleep (or a "coma" as I liked to say ha) to cool down.
Maybe someone should start a thread to post their unibody temperature readings? But I think there would have to be some standardization in the sampling as my CPU can run as cool as 50C and as hot as 78C depending on the load on the system.

IPHONE 4 Temperature too hot needs to cool down????

I waited 12 hours in line for my iphone 4 and got it today. Got it activated in the store, worked fine. When I got home, it started saying "Temperature too hot, needs to cool down". It wont let me charge or sync. The phone is not even warm, as I had not used it since i left the store..I have waited a few hours and I am getting concerned. Any advice please?

so the info in that link is correct.
No it's not. The directions given are for a Reset and no matter what you call it, following those directions will not erase any data or settings and will certainly not restore the phone to it's original state. I've done this hundreds of times and it's like rebooting a computer - nothing is lost.
Check the manual... http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf Search for the terms Reset and Restore.
Please learn the functions of the iPhone before posting solutions on a tech support forum.

Macbook pro retina display 15" charger getting too hot... any advice?

I have had my Macbook pro retina 15" since Jan 2014 and it has been working fine. Just recently, I have noticed that the charger block and the connector to the laptop gets extremely hot as does the actual laptop. I have looked around on the net and most of the discussions regarding this have been on earlier models. The charger block itself is so hot that it emanates heat and is too hot to touch! The plug into the laptop is pretty darn hot as well. When charging, I can't keep the macbook on my lap because it gets too hot.
I have checked all the connectors and the connections of all bits involved and they all seem good. I have also tried to minimalise all programs that are running.
Just wondering if someone can suggest anything, otherwise it looks like a trip to the store
Many thanks in advance

Bfore you run to the store try this SMC ret, it fixes

Ipad 32gb wifi, got too hot error, let cool down, then blue screen, won't reboot or power on

a friend's ipad got the too hot error message earlier this afternoon, despite the device never having been used outside and having been inside in a 68 degree house at the time. was being used to watch YouTube videos primarily.
let the device cool down.
then they got the blue screen, and now the device won't power up, acknowledge power cord plugged in, or reboot at all. no apple screen, no slider, nothing.
i'm guessing the device is totally bricked.
anyone have any other suggestions, before we call tech support (it's a company-owned device, not personal, and only purchased in september 2012 so still under warranty).
thanks!

Hi Buddy! Well I was up 'til 5am and NOTHING changed on the indicator lights OR the computer...gave it 'til I got up today (11am ish) and still NOTHING!(Just my power bill going up LOL) However, if I turn it off, back on, off, back on THEN press alt+f10 BEFORE it starts 'circling' I get: "preparing repair" right away which gets my hopes up BUT nothing.OK. So I have gone to look at the option of buying repair discs like you suggested, but the bleeping store web page keeps coming up "sorry ...we are aware of this problem...we are working on it" all in red ink. Yup, right, like you have great customer service too, yeah? grrrrrAnyhoo, wondering about this:a) could something be LOOSE? A neighbour told me her son had the EXACT same model and problem and just the RAM was loose. He had to pay $$ a technician just to fix that which took about 5sec. Could that be the case here? Something loose?b) Should/could I open the computer and check myself? What does the RAM board look like? Can I find a diagram somewhere that shows me a map of the inside of the computer? I am a craftsperson (jewelry) and I am quite confident I have the tools to open it and look inside...What do you think?
