Qosmio F50-10Z - fan cycling on and off even when idle

My f50 is constantly turning the fan on and off every couple of minutes, even when the machine is idle and has not run any applications.
SpeedFan shows that the GPU is cycling constantly between 55 and 65 degrees C even when there are no apps running (e.g. just after booting) - the fan kicks in at 65, turns off at 55 and then slowly heats up again. The fan noise is noticeable (I don't think it is going full speed, though), and it is a bit abrupt and annoying to be happening constantly and doesn't seem like normal behavior. Core 1 and 2 on Speedfan are cycling between 40 and 45 C
Outside temperature is 20 degrees, so the environment is unlikely to be a factor. I've air blasted the fan for dust (as much as you can seeing as the f50 isn't built to be taken apart by a Home User), but even when the fan is running the output doesn't seem noticeably hot.
I'm am only running toshiba drivers from the website (currently 7.15.11.7590)
My main concern is that this will negatively impact the life of the fan. Am I being overly picky or is there something I could be doing?
Thanks for any advice

Thanks for the reply Lars_3.
The notebook came with Windows Home Premium pre-installed - I haven't replaced the OS at all, though I have created a recovery disk at the urging of OS when I first booted it.
The BIOS is up-to-date as I use the Toshiba Tempro service (which again was pre-installed) and occasionally check with the website to make sure I haven't missed anything. I don't like the idea of installing drivers or anything else not released by Toshiba as I've seen people mentioning overheating shutdowns (at much higher temps) from using non-f50 drivers. I regularly keep the base elevated to enhance air circulation, and clean the intakes with compressed air, but it doesn't seem to make much difference.
Everything else works perfectly (and I'm a happy customer) except for the noise factor of the fan switching on every two minutes during even light use (not even 3d game use, which I assume would utilise the 3d card more and be expected to come with greater fan use).

LX835 fan cycles on and off (and on and off and...) at idle since 6.20 BIOS

Hi,
I have a new-ish LX835-D3215 AIO.
The fan started to cycle on and of constantly about every 30-50 seconds (off) and 10-20 second (on) when the computer is at idle. The CPU temp is about 30% and constant and the fan runs up to 75% of max speed; both according to the PC Health monitor. It does this even when the PC is supposedly sleeping. The computer did not do this OOB, but I believe it started after the 6.20 BIOS upgrade. I have recently upgraded to Win 8 but that has not helped (nor worsened) the problem. The fan winding-up and winding down noise is really infuriating! It is much more intrusive than when the fan runs constantly during normal operation, which is at about 75% and CPU at 42% temperature.
I am disabled and I bought this computer to place by my bedside, and it has become a big disappointment. I have to power down/up or manually hibernate it. (I recently added hibernate for this purpose). I have noted a few other posts of similar fan cycling issues in the forum.
Many thanks for any help. Anyone - please!

I figured it out. Here is what you do; Shut down your mac, then unplug the power cord. Turn your Mac back on and close the lid immediately. That solved my problem.

IPhone 3GS randomly turns itself on and off, even when charging

My iPhone 3GS 8GB keeps turning itself on and off randomly like every 5 minutes. It does this even when charging. I've had my phone for a year and haven't had any real problems out of it until now. It died on me last night so I plugged it into my charger. It came on then 5 mins later went off by itself and turned back on. It did this all night. I finally unplugged it to see if that had something to do with it, but it didn't. Anyone have any insight on this or ideas on how to fix this? I'd really appreciate it!
Thanks!

I'm getting both of these errors constantly. Everything used to work with my old Asus
z77 MB and I'm on my second MSI z87 G45 since I returned the first one thinking that it was bad. Now I'm thinking it's the CPU since everything else worked fine on my Asus z77.
PSU = I have an Antec 850w.
RAM = G.Skill 12800 8-8-8-24. It's is in XMP and the command rate is 2T. Ran
memtest overnight and it found no errors (after 4 passes).
CPU = 4670k
MB = MSI z87 g 46
SSD = Samsung 840 250GB. Wiped and reinstalled windows multiple times on 1st and 2nd z87 MB's.

What did the 2 other forums say?
Please run this test to find which driver is causing the problem.
If you are overclocking (pushing the components beyond their design) you should revert to default at least until the crashing is solved. If you don't
know what it is you probably are not overclocking.

MSI X99S Xpower AC Cycles on and Off

My rig has been stable for the past month (please refer to footer for components) and today it started to just cycle on and off in approximately 5 -10 second intervals. I downloaded and updated my bios 30 days ago, and it has been very stable. I also verified the BIOS settings today to make sure they were OK. However, today it just started to cycle on and off. When this occurs, the power supply is also powering on and off which may be the culprit. Could the power supply be going into hibernation with the CPU I have? Not sure how if it has been working fine. I also do not overclock at this time. Any suggestions on what to try?

Not sure how concerned I should be, however, yesterday when I was going to perform the tasks posted by pandaz, as well as perform the paper clip test on the power supply (this verifies the integrity of the power supply by taking the MOBO out of the equation), the issue did not reoccur from the previous day (it was off all night, but still plugged in). The first time this happened (shortly after building my rig about two months ago), simply clearing the CMOS took care of the issue (in review of my notes), and this time, clearing the CMOS did not, however, letting it sit overnight did. Do I have an issue I need to be concerned about? My legacy XPower Big Bang never had any issues after setting it up a few years ago. Thoughts?

Fans Constantly Cycling On and Off

About a week ago the fans on my dual 2.0 G5 running 10.4.8 started cycling on and off. After a few days of this I ran AHT and received the following error:
Error Code 2STH/1/2:CPUA AD7417 AD1.
I found out this was a possible problem with the logic board and immediately took it in to the local Apple authorised repair center. They tested it and found a Thermometer failure on CPUA AD7417. They removed both processors, reset the logic board,reinstalled the processors, and completed calibration. After which they ran ADT test and Apple G5 Service test disk twice. According to them the G5 passed all the tests and had no problems.
After I got home and set it back up the fans started cycling on and off just as they did before I took it in for repairs–they cycle on and off regardless of the ambient temperature or the amount of work the processors are performing. I ran AHT's extended test which it passed with no problems.
What's going on? Did they mess up when they were doing the calibration? Am I going to have the same problems that prompted me to take it in for repairs to begin with? Is there a serious hardware problem that they failed to discover?
The service was poor, and they even managed to scratch the **** out of the side of my G5, so I don't really want to take it back to them again. Unfortunately the closest Apple Store is about 4 hours away and my G5 is no longer under warranty.
Any suggestions about what's causing the problem and what I should do would be really appreciated. Thanks.

Blinn–
Nope, I hadn't installed a software update. It just came out of nowhere. If you haven't done so, I reccommend running AHT to see what it shows. Hopefully you're just having a software problem.
DaddyPaycheck–
Thanks. That clears it up. I am definitely going to call Apple. I am really fuming about the lack of service I've had from the "Authorised Repair Center."
UPDATE
It just keeps getting worse. Now the G5's fans are really revving up and it is putting itself to sleep with increasing frequency. I just got off the phone with the guy who "repaired" it. The reason that AHT is showing the same error code, but on processor B is because when he reinstalled the processors after resetting the logic board he switched them. According to him, this error shows that it is a problem with processor B, which will need to be replaced. It's going to cost $581 for the CPU–no charge for labour since I've already paid to have it fixed once even though it wasn't!–but I don't think I want anyone at that shop working on it again.
Has anyone else replaced a CPU in a dual 2.0 G5? How much did it cost you? Is this something that I could do myself?
I think that before I do anything else I'm going to take DaddyPaycheck's advice and call Apple. At least then Apple will know that this authorised repair center is doing a terrible job!

Qosmio F50-10Z Bios update crashed - how do I reset cmos?

I have a Qosmio F50-10Z and as prompted by toshiba I downloaded the Bios update and began to install.
My screensaver came on and the whole thing crashed.
Would not turn off (even after holding down power button for 15 secs).
Took battery out and then put it back in. Computer powers on but screen is blank and won't boot up.
Tried to take it apart to flash the bios by taking out rtc/cmos battery (whatever it's called) but can't find the battery and got to the point where I wasn't willing to take it apart any further (has no-one else ever taken one apart?
Couldn't find information or diagram or photo of where the battery was on net...manual for laptop really unhelpful)
Have found comments about crisis disks but I don't know what this means.
So, how to I reset bios?
Please help - you are my only hope.

Thanks for your comments. Do you know where I can download a Bios flasher or Bios recovery crisis disk from? There seem to be a lot floating around forums but I cannot find anything specifically for my laptop. Am I missing something on the Toshiba website? I have seen people mention downloading a bios flash utility from toshiba (specifically for the F45) but can't figure out where they are getting this from...
In response to your recommendation - I know that is what I am encouraged to do but I'm in the UK - my nearest Toshiba recommended technicians are PC world conglomerate - the sort of guys who pat me on the head when I ask for specific RAM (rather than 'some memory, please'), look blankly at you when you say the word Bios, and bang their mouse when the computer freezes! Besides, they want 50 up front whether or not they manage to fix it, and given how many of my friends computers they have failed to fix that my boyfriend then fixed in ten minutes, I might as well burn my money as send it to them.

Card Reader issue on Qosmio F50-10Z

I have had this issue for a while, It began with the original os Vista 32 bit, so i decided to buy the toshiba upgrade cd for windows 7, after upgrading everything worked fine, except the card reader, no matter how many times i installed/uninstalled,installed the driver it would not work!.
So I used the recovery cd, not once BUT TWICE, and to no avail i sent it off to repair.
I got a message on a piece of paper telling me it would work on the original os, i thought they had fixed something.
So i used the recovery cd yet AGAIN, and to my short lifted excitement of seeing no yellow explanation marks i put in a micro sd card (2gb) which initially worked when i first bought this laptop, and got no response.
The bigger problem is my warranty is now finished!, So basicly i have been BUMPED OVER, cause the memory card slot is NOT WORKING, and it wasnt an software related problem!
Any reccomendations?.

Hi karimtarek,
Which driver version you are using on Vista and Windows 7? My Qosmio F50 is running Windows 7 and Im using driver version 1.00.29.02 from the Toshiba page.
Are you using the same version?
Furthermore it would be interesting to know if the SD card slot worked after you got the notebook from service center back. Have you tested this before or have you started recovery installation immediately?
Have you tried different brand of SD cards? I always use SanDisk Extreme cards because they never made any problems.
Furthermore you could try updating the BIOS. Maybe it works if you using a pretty old version
Last but not least if its still not work and you think its a hardware malfunction, ask the service centre again. If you speak a little bit with technicians, maybe they can repair it as a gesture of goodwill.
Good luck! :)

Time Capsule HDD keeps cycling on and off while my Mac is sleeping

Hi guys, I'm in a bit of a hurry so just gonna post dot points:
• My Time Capsule's HDD keeps cycling on and off continuously and potentially doing heaps of damage to it's drive when my MacBook is sleeping.
• Time Machine is set to automatically backup to my time capsule.
• As soon as I wake up and log into my MacBook it seems to stop. I checked the time capsule icon immediately and it says "Preparing backup" so I assume it was stuck in that phrase.
• I assume it backs up normally after waking up
MacBook Pro Retina:
• I usually never put my MacBook to sleep by closing the screen, so can't say if this happens when it's in closed screen sleep vs open screened sleep
• I'm not sure if there's any difference between close screen sleep and open screen sleep
• It is set to go to sleep automatically after 45mins of inactivity
• My iTunes Library is stored off-device on a 2TB HDD connected to the Time Capsule
Cheers,
Tony

How old is the TC and on what firmware?
You have put Mountain Lion for OS.. is that still the case or upgraded to Mavericks??
There has been some issues at various times with disk spinning up ..
This thread might give you some clues.
https://discussions.apple.com/thread/4148904?start=0&tstart=0
Is the computer set to power nap? Try turning that off.
Try unplugging the external drive with itunes library and see if that helps.
If it is TM the attempts to start the backup should be in the log.

Power nap.. try unplugging the laptop from power.

Phone cycles on and off. I have restored and so has the apple store.

I had a screen sensitivity issue with my original 4s. It would react to my finger getting within about 1/4 inch of the screen, and would auto dial without anyone touching the screen. Fortunately, It happened to actually do this in front of one of the 'geniuses' on my third trip to the apple store so they replaced the phone about 5 months ago. I was given a 90 day warranty on the new phone. It worked fine until last week.
It started cycling on and off. Then it wiped the phone and all of my apps. I restored the phone but there would be a noticeable hesitation between when I touched the screen and when the touch registered. This went on for two days.During those two days the power indicator did not ever show any indication there had been any battery drain, but always showed 100% charged, days, then went dead without ever showing it was discharging. I took it to the Apple store. They tried to do the same restore I had. The phone came back on, but then cuts on and off to the Apple logo. The battery will take a charge, but as it sits on the charger it cuts on and off. The store solution was for me to purchase a new phone since they either had no idea what the problem was, or wouldn't tell me. The phone has not had rough treatment or been exposed to water or excessive moisture. Any suggestions?

try to force restore using: http://support.apple.com/kb/ht1808
If that doesn't work, I'm afraid the device needs another hardware repair.
Please note that using that article will erase everything so make sure you've got a backup.
But restore it AS NEW if it's at all possible.
Good luck

Airport cycling on and off repeatedly

I have a time capsule purchased March 2008. The updates are current. Had no problems until the last 2-3 days. Now, it is cycling on and off. It will not stay connected to the internet. The light goes from green to yellow to off to yellow to green. I have shut everything off, unplugged the time capsule, the DSL, ran the disk repair utility.
There are no clicking noises. When it is working with the green light, all seems well but it keeps shutting down.
Is it broke? Software problem?

Will I loose all my backups when the power completely fails? It is a 2 terrabyte hard drive and I have it full with 2 machines backed up on it.
The data should not be affected as it is stored on the internal hard drive ... which (push comes to shove) can be removed. One thing you can do, is if you have another USB drive handy is to perform a data archive to add some additional "insurance." You have been doing these all along, haven't you?
I can get the Apple store to put a new power supply? Or should I buy a new time capsule?
There are no replaceable parts that I am aware that Apple will perform on the TC, but it would be a good idea to have the Apple Technician give the TC a good look at to verify if even the power supply is an issue in the first place.

GMail cycles on and off on iPad

Sometimes, when I open the Gmail App, the Gmail screen cycles on and off. Then I go to Safari, to access Gmail and it opens normally. Why does the Gmail App cycle on and off sometimes?

Close the Mail app in the Task Bar and re-launch.
Double-click the Home button to reveal Task Bar. Hold Mail app down for a second or two; tap the minus sign to close app.
If it still doesn't work, try a reset.
Hold the Sleep and Home button down (together) for about 10 seconds until you see the Apple logo.

Continues to cycle on and off on boot

mac will not boot up, continues to cycle on and off. Apple logo is displayed and chimes, then will cycle to black screen and then on again. tried to use cmd R but does not go to gray screen

Version of OS X, what computer? Most of us uninstalled our mind reading app, they didn't work anyway?
Run Apple's Hardware Test in extended mode 2-3 times back to back. If errors appear that confirms it's a hardware issue and needs to go in for service.
