IBook Cooling Fan not working correctly.

My G4 iBook's cooling fan no longer comes on. It gets really warm after being on for a while, but the fan does not come on.

Yes. The new iBook 12" that I have is confirm to have heating problems with the Toshiba Hard Drive 40GB. I have sold like 20 of them that have such issue. And I have one as well!
I am going to call apple care hotline to find out later.
Because the hard drive is so hot and really shoot up to 70C when I switch on the Processor to highest performance in system preferences setting.
and it will shoot up to 6xC when I am just listening to iTunes for more than a few hours.
I think Apple should change a better hard drive for users.
because I do allot of typing and i could felt my left palm is actually very uncomfortable, especially when i am doing multimedia scripting and typing some database information. It just gets near to a burning state if I keep my palm longer there. Currently, I am using a cool gel pad for eyes to keep the heat in control and my palm away from it. I have a powerBook Pismo before that the bottom of the machine is hot. That's OK, because i work allot on table top even going out. This is annoying with the left palm rest heating problem.
I hope Apple should take note on this serious heating hard drive and change it for all the users soon.

Cooling fan not working...????

when i m turn on my laptop...
there is message display that cooling fan is not working correctly..???
& shut down after 15 sec now what is the problem is happen???

We need the model number of the laptop to give detailed help. One thing you can try is to remove the battery and AC adapter. Bent out a paperclip and stick it in the fan grille to hold the blades. Blow in compressed air. Now put the AC adapter in and start up. Tap F10 to enter BIOS. As you leave reset BIOS to default. This may remove the message. If not the fan needs to be replaced.

PAvilion dv6, fan not working correctly?

Was on my laptop, it shut down randomly, notification popped up saying fan was not working correctly. Is there a way to fix this? Or will it have to be sent away?

Try a can of compressed air in the reverse direction of the normal air flow. You may just have a massive amount of dust on the inside of the heatsink near the fan blades.
Here is a youtube video and about 15min in you can see the fan clearly:

Cooling fan not operating correctly

Upon pushing the start button the laptop displays a black screen with the message that system fan 90b is not working correctly. The fan seems to make no noise and may possibly be dead. It tried to start up once without displaying that message, but showed it all other times. Would like to know if it would be possible to confirm that fan is indeed dead before I attempt to replace it, and also how difficult replacing it myself would be, as opposed to having a professional do it.
Problem started after attempting to clean computer's vents with vacuum. Wondering about proper cleaning method, had been previously advised canned air could make the fans turn in reverse and cause damage. Have cleaned laptop vents with vacuum in past and experienced no problems.
It's a Presario CQ56 running Windows 7 Home Premium, had it for 2-3 years and never experienced this sort of problem before, although computer sometimes runs hot and slow. Had laptop's screen replaced once because I dropped it, other than that never had it repaired as far as I remember.

Cooling Fan Not Working Properly

Hello,
i have an HP Pavilion g7 laptop and when i turn it on, it states the fan is not working correctly, then shuts down after 15 seconds or continues to windows if you press enter. I cleaned all the air vent with compressed air and still get same mesage when i power up. The computer seems to work fine otherwise, but sometimes the fan will run at rather a high speed all night even when it is supposed to be "asleep" with the cover closed. I have to make it hibernate to ensure that it does not run all night like that. Do I need to replace the fan and if so, how?
Thank you!
Rick

Yeah im having the same problem with the same laptop. Im kinda pissed about this because the first month i owned this laptop, that same fan broke and i had to send in into HP to be replaced. So now here we are again with the same part broken.
My friend also bought the same laptop at the same time as me and his fan also broke. So clearly this is a defective part. Not only that but they broke my keyboard during the fan replacement.
So HP are you actually going to do anything about this because i was just on your FB page and repeatedly got ignored by the chick TINA who runs the page or whatever.
So im not too happy at this point, so whats gonna be done about this HP?

Cooling fan not operated correctly

i am getting a message on start up - " The system has detected the cooling fan function operated not correctly"

We need the model number please. Can you get past the message or does it block you from booting? Remove the battery and AC adapter. Get a paperclip and stick it in the fan outlet grille to hold the fan blades from spinning. Blow in compressed air. Now hold down the power button 30 seconds. Now connect AC and boot to BIOS (F10). As you leave the BIOS reset to default settings and see if we can clear the message. If not the fan needs to be replaced.

Lap top pavilion dv 7 shutting down Error 908 cooling fan not working

Since two days my HP pavilion dv 7 lap top has been heating up. I started getting warning notice error 908. One of the cooling fans apparnetly is not working properly and the system is shutting down.

If the operation has slowed you might also want to check the hard drive. Go back into the BIOS and look for the hard drive diagnostic test and run it. If the laptop came with Windows 8 you can also go into the "enhanced" diagnostics which is easier to use, with mouse support and such. Tap F2 as you power up instead of F10. You can run a whole bunch of diagnostics in there like memory and hard drive and DVD drive. Let us know the results.

Hp pavilion g6 1000sa cooling fan not working

My hp pavilion g6 is displaying the message cooling not operating properly please turn off or risk causing permanent damage
This question was solved.

Well it is either blocked, has a bad BIOS setting or the fan is dead and needs to be replaced. Try sticking a bent-out paperclip in the grille to hold the blades and blast some strong compressed air in there. Also try a hard reset....remove battery and AC charger and hold down power 30 seconds then plug in and try again. Also go into BIOS (F10) and set BIOS to default settings. If that does not work it has to be disassembled and the fan replaced.

Hi
I think it's indicating to replace the fan and heat sink assembly.
It occurs due to overheating & this decreased performance.
Try to do a hard reset first.
You may try doing a COMPLETE HARD DRIVE TEST & COMPETE MEMORY TEST from BIOS soon after powering on the system & pressing F10 or F2.
If you want any help, post back.

HP PAVILION DV6 6154FAN NOT WORKING CORRECTLY

MY LAPTOP FAN IS NOT WORKING CORRECTLY A STARTUP MESSAGE COMES FAN NOT WORKING CORRECTLY GO TO SUPPORT FORUM.
MY PRODUCT WARRANTY IS OVER.
PLEASE ADVICE ME WHAT TO DO.
SEEKING FOR KIND SOLUTION.

Try cleaning up the cooling module. Blow compressed air into the fan grill. Test the laptop after the fan and heatsink is clean.
If cleaning the cooling module doesn't help, you'll have to replace the fan. This requires complete laptop disassembly.
In order to replace the fan you'll have to remove the motherboard.
Here's the official service manual which could be useful.
By the way, there are two different types or cooling modules. One for AMD processors and another one for Intel processors (page 93 in the service manual).
If you decide to replace the fan, it's not necessary to replace the entire cooling module assembly (heatsink and fan). It's possible to replace just the fan which can be purchased on eBay.
