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 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.

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.

Message on bootong the laptop that cooling fan is not operating correctly

tell me ..how can I resolve my laptop problem

Bend out a paperclip and put it in the fan grille so it holds the fan blades. At the same time, take a can of compressed air and blow it in there. This may loosen a dust clog and allow the fan to spin correctly. If that does not work all you can do is disassemble the unit and replace the fan.

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.

Power fan 'not operating'

Hallo, I have h535 desktop.
In BIOS is written that my power fan is 'not operating'. But it looks like PSU is working nornally and is quite cool.
Why there is in Biios such a statement?
Solved!
Go to Solution.

Having a 7200 RPM hard drive is another reason to leave the fans all plugged in and the side cover on. A 7200 drive will generate more heat than a 5400 RPM drive. That's why a lot of laptops will have a 5400 installed instead of a 7200.
If vibration is a problem you could try inserting strips of rubber like from an inner tube at the points where the drive contacts with the drive cage. Then secure the drive screws, but don't over tighten them. It is also possible that the vibration you are hearing is from the drive cage itself. When the drive is working, try putting little pressure on the cage at different points to see if the vibration quiets down.

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.

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:
