CPU temps rise 10c and fan RPM goes up by 1K on resume from suspend

Unfortunately, it will be hard to determine what update prompted this issue as I didn't notice the problem right away. However, recently my Thinkpad x220 began experiencing a 10 C increase (as reported by sensors) and a 1k increase in fan RPM on resume from suspend. I started to suspect the suspend being the culprit, so I ran sensors, it came back with 44C temp on my cores, and a 1900 fan RPM. I suspend the system and then bring it back. If I run sensors again immediately upon resume the core temps have risen to 55C and my fan RPM is around 3K. A reboot of the system corrects this issue and brings the temp and RPM back to the pre-suspend numbers.
System is up to date and uses Kernel 3.6.1 and testing repo. I am getting ready to back down from testing to see if the problem goes away, but, has anyone notices similar behavior?
Update: I have narrowed the problem to kernel 3.6.1. Temp and fan are working normally after moving back to 3.5.6.

This should probably go in the Testing section.

Desktop visible after resume (from suspend) and before screen is locke

My desktop becomes visible for brief period (<1s) when the system resumes from suspended state. My desktop env. is XFCE4, it happens with both xscreensaver and gnome-screensaver (also with slimlock and i3lock), therefore I think it's not locker dependent. It's a major security flaw because sensitive information may be exposed (not just porn). Using both XFCE provided locking facilities (suspend/resume lock options in Power Manager and Session settings), and systemd suspend/resume hooks yields same result. I remember back then when I was using Gnome, I haven't had this issues. Does anyone have any idea how to prevent this desktop expose?

Fans rpm going all or nothing

I have a weird problem in my macbook pro 17"
The fans start out at 2000 rpm, which is as it should be,
Then after some time they go 6000 rpm in one go.
Then they lower again to 2000.
it seems as if there is no inbetween for them, all temps look ok, nothing is hot, no processes going nuts.
This also happens when I am at the Boot selection and OSX is not even loaded.
Things I did:
Install iStat pro to check the rpm and temps, all temps look okay
Checked for out of controll processes on all users, nothing wrong
Checked if it happens on all users > thats a yes
Checked if I can manually set fans rpm at 3500 > thats a yes! (so technically it can do it)
Reset the SMC, no difference
Ran a log over a long period of time of temperatures, no relation found and no exessive temps
One thing I do notice is that I see the battery usage go down a lot when the fans ramp up, this leads me to believe that something does happen and the mac reacts to that.
I just do not see anything to make the same conclusion as the mac
I am at a loss here, The mac seems to read all temperatures fine, it can technically controll the fans to all speeds but it doesn't do that in use.
It starts at 2000 and then all of the sudden it will make the fans go to 6000.
Then drop to 2000 to go a little later again to 6000.
Does anyone have any tip for me?

Found in the service manual that the TsoP sensor is the one on the Topcase.
a shame that istat pro does not show that sensor, does anyone know how I can see what that sensor is doing?
And does anyone know where it is mounted?
I cannot afford a completely new TopCase, so I am hoping to find the cheapest way for me to get this fixed. Hope I can find someone that has a topcase lying around or something smiles

CPU temp with Zalman9700 and MSI P965 Platinum ?

Hi.
its funny. My old Asrock DUAL-VSTA showed CPU temp and other temps in programs like HMonitor and Speedfan but this
MSI dosent show anything about CPU in any programs ?
I must say, i was a little confused when i installed the board because there was 2 CPU fan slots, one with 4 pins and one with
3. I have a Zalman CNPS 9700 LED, very nice fan btw. Shoulden this fan be controled by the CPU automaticly ? i do have a
fan regulator in the end of the wire outside the cabinet. I have it on the bag side of the computer case so i can turn it op and
down. But i think i read someware that it could be controled automaticly. Is that right ?
And what about the 3 and 4 pins CPU fan slots on the board. Right now i cant remember in witch of the 3 or 4 slot i installed
the fan in to. But anybody know witch slot is the right one for my CPU fan ?

Listen. Forgot to say.
I'm still a little little bit concerned about 40c-41c idle. but but.
Relax, it's quite alright...
Quote
But what i was trying to say is. I have 3 running SATA drives also and only the stock (Normal) 120 fan that came with the Antec case.
1 fan, the Zalman 9700LED and the PSU fan ofcause. and then OC at 300FSB. Could that be why i'm at 40c idle ?
All the drives + only 1 fan in the case ? i mean. I'm not shure the standard 120 fan that came with the Antec case is good enough.
Any sugestions ?
My case has three 120mm case fan in addition to the 120mm power supply and the Zalman fan, five of them altogether. The Antec P180 case has separate compartment for the hard drives and the power supply, which made a big difference from the temperature's perspective. The box also has four hard drives and I do not OC; I did try, but I didn't see much of a difference and shut it off.

btw. what is a good stress test apps to test my cpu temp with on max load ?
The Orthos Stress Prime is pretty good and so is Intel's TAT; the link I've posted earlier has more information.

When I click on a link in an email, the comoputer locks p and the screen goes black, requiring a shut down from the on-off switch. My version of Firefox is up-to-date.

The on-off switch is the only way I can turn off the computer, because the screen is black. Then I turn on the computer again to reboot, and when I click on Firefox again it takes from 30 to 90 seconds before Firefox opens, at which point I get a message asking if I want to begin a new session. Then I open emails and don't click on any links. If I check my email using Internet Explorer, the problem does not occur. Your help would be appreciated. After 50 years of operating comoputers, I have never seen this problem. Regards----Lloyd Schultz

Fred...thanks, but this is not about one site. The same thing happens often, with many sites, when i click a link that has come up in Google search, or on Twitter or Facebook or within a story I'm reading. The link takes me to the url of what it was supposed to take me too, then within a second or so it switches to that Yahoo 'error handler' url, a page that offers search for similar sites.
Again, thank you.

Screen goes dark on resume from suspend

I have some problems with my video driver and suspend to ram. When I try to resume after suspend, my screen goes blank (dark). I tried restarting X, but nothing seems to happen. (The computer does still work when the screen is dark, i can ssh into it.)
The computer has an ATI radeon 9600 mobile graphics card, and it's using the open source "radeon" driver.
Im pretty shure this is a graphics driver iusse, because suspend works somewhat with the catalyst driver. (With catalyst suspend works once then crashes when i try to suspend a second time).
I have read the wiki entry for ATI-cards but it doesn't say anything about using suspend with the "radeon"-driver.

Computer froze and fan started going faster by the second. What could've happened?

I was using my computer (MacBook Pro Retina 13") and suddenly it froze and the fan speed was going higher by the second. I had to switch off the compute before something serious happens.
I did the EtreCheck after reading some of the responses. Hope this helps in figuring out what is going wrong. Also how to minimise the CPU usage and reduce the RAM as well?
Problem description:
My computer froze and the fan (I guess it was the fan) starting blowing harder and harder and harder by the second. I got worried that It might blow up or burn up so I switched it off immediately. Most of my memory is used up by Kernel_task and I am not sure what that is!

Hello Abed88,
Thanks for using Apple Support Communities.
After you restarted your computer did the issue where your fans were spinning at a high RPM and the Mac became unresonsive come back? If so I recommend that you start with doing an SMC reset.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Take care,

93 degrees celsius CPU TEMP!! and performance is degrading

Hey Guys.
I have had my MacBook Pro for about 10 months and now my battery is at 60% health one day and then will fluctuate to 89% health the next.
Recently too, a lot of software has been hanging up and I get the rotating beach ball of doom. The machine has also been running rather unusually hotter than normal. For example I'm just watching a YouTube Video and listening to music in iTunes at the CPU reaches a heat of about 75 degrees celsius. About 5 months ago this would only occur if I was rendering or encoding files. Last night I was encoding a movie into MPEG4 and my CPU reached a whopping 93 degrees celsius!!!
I have tried resetting the Power Management control but that didn't help.
Is anyone else having similar issues?
Thanks in Advance,
Chris Hall

Hi Chris,
Oh, your battery health fluctuations might be related to the heat issue your experiencing, since lithium polymers hate heat. If your using the system plugged into it's adaptor, you can prolong the battery life by removing it, once it's fully charged. Your MBP will continue to run but remember to insert the battery before you unplug cause the system will just power down/shut down; thus lose work.
Do yourself a favor, try saving your CPU's from overheating, they're gonna die if they keep on being cooked or fried!!! I found this utility that give me more control over those internal fans, i'd advise you to tweak the default speed from the standard 2000 RPM to a more realistic 2200 RPM (anything above 3500 RPM starts becoming noisy).
Personally, I've managed to lower the processor temps from the frightening 71-75°C to a more comfortable 50°C. Give it a try and tell the rest of us what you think.

Good luck.

Satellite R830-1GZ - CPU usage high ( 25%) and fan speed increase after wakeup

Hello all
The CPU usage of my laptop shoots up to 25% (and beyond) and the fan speed increases dramatically after waking up, but only when I'm using an external mouse (Microsoft Natural Wireless Laser Mouse 6000) - disconnecting the mouse once this has happened does not solve the problem, so I'm always forced to restart my computer if I have let it go to sleep with the mouse connected.
I've noticed that when this happens System Interrupts - Deferred Procedure Calls and Interrupt Service Routines appears in the Resource monitor>CPU>Processes, and seems to explain the increase in CPU usage.
Any ideas on how to fix this would be most appreciated.
I'm using a Toshiba Satellite R830-1GZ with Windows 7 (64 bit). This problem does not happen when I use the same mouse with another laptop (Dell with Windows XP).
Thank you very much.
CM

Thank you for your reply.
I was using the mouse without installing the software that came with it (IntelliPoint), which seems to have been necessary to obtain the latest driver. So I've installed the latest driver now, but... I've still come across the same high CPU usage problem after wakeup.
If your suspicion is correct, should disconnecting the mouse before putting the computer to sleep (hopefully allowing the process that controls the mouse to close properly) stop this problem from occurring when it wakes up?
Could this problem also occur due to an external keyboard? I'm pretty sure it's the mouse (given my experience of using only the external mouse and only the external keyboard) and my understanding is that keyboards don't require special drivers (at least the A4Tech one I have claims it doesn't)... just trying to exclude all possibilities.
Thanks again for your help.

Bdb(4.4 and 4.7) goes to infinite ride when used from 8 core box.

We use bdb-4.7(This bug is reproducible with bdb-4.4 too) with subversion 1.5.
When we run 'svn log -g' in one window and 'commit in another window' we could see 'infinite' loop inside bdb code.
I could trace the infinite loop to the following code.
#define     SH_LIST_NEXT(elm, field, type)                         \
     ((elm)->field.sle_next == -1 ? NULL :                    \
     ((struct type *)(((u_int8_t *)(elm)) + (elm)->field.sle_next)))
In our execution context (elm)->field.sle_next happened to be 0.
And hence infinite loop.
I am not sure (elm)->field.sle_next need to be guarded at the population stage itself or at SH_LIST_NEXT.
This bug happens only with 8-core box with bdb data being from NFS.
I believe the following patch should fix this, but I am concerned about applying this patch to bdb code that used to work fine for so many years.

At a Genius Bar appointment yesterday, we determined that I needed to go to Mountain Lion from Lion. I purchased Mountain Lion at the Bar, and paused the install so that I could resume from home. Now I can't find it to resume. Not in Downloads. ?????

When I upgraded to Lion, my Parallels stopped working and I got a Bootcamp error message. It had worked fine for the prior year. I upgraded to Parallels 7. No luck. At the Genius Bar, the Genius uninstalled Bootcamp. No luck. I still get "The Boot Camp partition /dev/diskOs4 used by Hard Drive 1 is missing."
Another Genius suggested upgrading to Mountain Lion. While at the Bar, I purchased Mountain Lion and then we paused the install so that I could resume it at home. Once I got home, I can't find the Mountain Lion installer to resume. It's not in the Downloads file. Any clue?
My business programs all run on Windows, so I have to get it operating. The Genius Bar isn't much help. Does anyone know how to get Mountain Lion installed? How to get Parallels working?

The "Geniuses" (and I use that word in sarcasm) at the Bar are lying to you. Upgrading from Lion to Mt Lion will not fix whatever problems you are having. In fact it will most likely make them worse.
If you want to try installing Mt Lion to fix the problems you are having you will need to open the Mac App Store link in your Dock, Login to your Apple ID account for the MAS and go to your Purchases area. Mt Lion should be in there and you will be able to do a proper download. Once you either set your Mac into sleep or shut down and then left the internet connection at the Bar all record of that download was lost. So you will need to restart it again from the beginning, like described above.
Good Luck

Resume from suspend and linux 3.6

I have installed Arch using LVM over an encrypted partition using this guide: http://www.pindarsign.de/webblog/?p=767
Until kernel 3.5.6 suspend was working fine. Today I upgraded to 3.6.2 and now this happens:
It seems to suspend fine, but when it resumes I get input/output errors and I cannot run anything. It's like the hard disk hasn't resume...
I don't know how to debug it. Any ideas?

Have you tried this --> https://wiki.archlinux.org/index.php/Pm … or_suspend ?

of background apps running, then 85 to 90C is in fact to
hot.
I have a new Mac Mini Server connected to a Thunderbolt
Display and have been surfing for a couple of hours and
have a CPU temp of 47C and fan at ~2300 RPM.
(Note: room temp is 21C)
If your Mini is running that hot, the fans should be roaring!
What is your fan speed?
BTW, the only time I hit temps like that is when I am using
Handbrake to do video conversions, which will max out all
cores available. The fan gets up to ~4500-4800 RPM.
The only time the Mini should get that hot is if you have
something running that will max out CPU usage. Check
activity monitor to see if there is some process that is
"running away" and forcing CPU to max out.
If the fan is not working properly, you may need to do
an SMC reset. If it is not working at all, get it fixed.
So, in conclusion, light CPU usage should not make the
Mini that hot!

CPU Temp and CPU Fan Speed

I am having a strange problem . One time I will boot the PC and CPU temp is 43 and CPU fan speed is 1308 rpm in Core Center. I do a restart system and the CPU temp is 32 to 36 and CPU fan speed 3308. Not sure if I should trust Core Center . Bios shows CPU temp 48 and fan speed of 3328. I have been reading here that there are a bunch of threads containing some kind of problem with CPU temp or fan speed. My Bios is 1.4. If anbody can give me some ideas that would be great.

Open CoreCenter on deshtop. Click where it says CoreCenter. Click Cool&Quite button. Then Click apply. This drops the fan speed back into the 1400 range and the temp will rise back to the 40s.

Macbook pro 13' 2012 fan problem? (high cpu temp)

my macbook gets cpu temp at 98C and then the fan starts raising speed from the default rpm(2000rpm).
with heavy cpu usage and cpu temp at 93-100C, tha fan waits about 2-5 minutes and then kicks in and increase the rpm( the higher rpm i saw was 4000rpm at 101C cpu temp). all the other time the fan speed is between 1995-2004rpm.
Is this normal?
I've already tried SMC and PRAM reset and clean OSX installation.

thank you for your answer.
But is it normal for the fan to wait so long 2-5 minutes and then start raising the rpm?
I expected that the rpm will go up simultaneously with the Cpu temp. Like if the Cpu starts increasing temp (about 70-80C) the fan will kick in...
I know from a friend with a Macbook retina that his fans keep spinning at 3000-4000rpm and always keep the Cpu temp close to 60C. I know that the architecture is diferent but the cooling logic should remain the same. right?

CPU temps rise 10c and fan RPM goes up by 1K on resume from suspend
