Start up screen black saying cooling fan error

I recently turned my computer on and right away pops up cooling fan error. Further use might damage computer. Something along the lines as that. I've done what they told me with using canned air and blowing that through the vents. And I turned it back on and it still came on with that screen. I need some help please. I know I've owned this laptop for about 3 years or so but it's worked perfectly fine since I bought it. I really need someone to guide me on what I should do!

Hi kyliek23,
Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the cooling fan error message. If you already used canned air to clean out the fan then you next step would be to replace it. If you can provide me with your product number I should be able to find a user guide that will show you how to replace it.

Cooling Fan Error Message & Computer Shut Down

Hello,
I have a 2 1/2 Satellite running W7 and recently started having a problem, receiving a Cooling System error message which tells me to shut down the computer immediately. I did and left it off to cool, then started it up again. Less than 5 minutes later, same message and the computer shut itself down. The fan starts normally, then becomes burdened, then stops. Is this actually fan related or hard drive related?

Hello Peter,
I already have the new BIOS you sent me. The problem persists. Toshiba has no Authorized Service for computers where I live (Brazil) as far as I can see on their site, which I can't understand since it is a global company. So, I can not use my business computer now. Apparently, I either have to ship it to the States (which will cost me more than the computer is worth, and I'm better off buying a new one of a brand that takes care of its customers globally), or I have to try and find someone here who thinks they might be able to discover the problem and fix it. Any suggestions?

Are MacBook Pro cooling fans on at start?

My mid-2009 MBP has a noisy fan -- the one closest to the middle. It is easily fixable but something else concerns me: When I start the Mac, at least the noisy center fan starts up right away (I don't know if the fan on the left starts). I thought the fans were not to start until the internal temperature reached a certain point. Is there another problem?

The fan(s) will always be running at startup. I believe the minimum speed on newer models is 2000RPM.

Cooling Fan is not working properly

I have taken this laptop around one and half year back.iam getting cooling fan exception while starting the windows.Please tell me the solution.

Sometimes it is simply dirt,dust,pet hair,etc clogging the fan. Pick up a can of compressed air and blow out all of the vents, ports & other openings. Clean it really thoroughly, then check to see if any change before resorting to changing the fan.

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 Spectre XT 13-2005tu - Cooling Fan Countiniously Running At Top Speed From Start Up

Ok, Here's a puzzler if anyone can help. HP Spectre XT 13-2005tui7-3517U @ 1.90Ghz4.00 GB Ram256 SSD HD Has been a great laptop, very happy with it, small light powerful, etc, good battery life, everything I needed as student and as someone who travels a lot for work. Towards the end of 2014 the hinges on the screen gave out. Outside of the warranty period HP were kind enough to fix it, however this didnt get completed until approximately Feb 2015 - when I returned from travelling. At the time they gave it a full service - cleaned it up, updated bios, replaced fan. The cooling fan was replaced as they claimed it was noisy, but to be honest I had never noticed it. As soon as I took it home, the fan went crazy. From the moment the power button was pressed it would run flat out and non-stop. Sometime it would change from flat out to nothing every two seconds for 5 minutes - I took a video of this at the time. I had planned to take it back to the service centre but after a few hours it returned to normal. There were no problems for a while, every now and again it would startup and run flat out constantly for an hour or so but would always go back to normal. A couple of days ago it started this again but just won't stop. The moment the button is pressed it is running flat out until the moment it goes to sleep or is turned off. It has also started with the occasinoal intermittent 'running flat out, then slowing down then flat out then slowing down' continiously over about 5 mins (I took a small video of this as well - https://youtu.be/P2ybdunCZf8). I have: - Updated anything and everything. - Formatted the pc and reinstalled windows. - Rolled back and reinstalled the bios. - Made sure the bios setting to constantly run the fan was off. - Checked that the fan was sqeaky clean. - Installed and monitored temps with HW Monitor - fans run flat out at any CPU temp. - Ran HP system diagnostics that show no errors. - Tried hard resets. - Also checked the CPU usage - fan runs at high speed whether 5% or 95% is being used. - Tried different power settings and changing the CPU Cooling policy within the power settings. I am out of ideas. I have a feeling it might be a hardware fault and that I'm doomed but I am keen to know if anyone else has any thoughts, and espeically if there is anything HP can do or recommend. Cheers

Hi , Thank you for your query. I understand that you had the display replaced by HP as it quit due to a hinge issue. When you got it back after they had done full service - cleaned it up, updated bios, replaced fan. The cooling fan was replaced as they claimed it was noisy, but to be honest you had never noticed it. As soon as you took it home and powered it on the fan went crazy,running at full speed non stop. The speed sometimes would change from full to nothing every 2-5 minutes. After a few hours it seemed to settle down and work normally.Occasionally the issue would return for a hour but then return to normal.A couple of days ago the issue returned but now remains constant. Here is a link to HP Notebook PCs - Fan is Noisy and Spins Constantly, PC is Warmer than Normal. As this did start just after the repair, I would contact HP support, explain the issues and get your options if the above has not helped.Please contact HP support at Contact HP Support.

Fan Error: Hard Drive-related?

A few months ago, my computer was running super slow. I ran the AHT and it showed I needed a new left fan.
When I took it into Apple, they diagnosed that, in addition to the fan, my hard drive was failing and needed to be replaced.
I took it to an Apple provider, told them the problem, and then they replaced the fan and not the hard drive. They said that with the new fan, the hard drive started working fine.
I am now having the fan error again, on the right side. I'm wondering if this is just a coincidence, or if it's related to the other issue. Is it possible that the hard drive failing could cause the fans to fail?
Thanks!

The left fan failing is probably why the right fan failed, as the right fan probably had to work harder to compensate for the failing left fan, and thus it was overworked and became compromised as well. It's usually prudent to replace both fans if one fails.
If your hard drive was failing back then, it's likely still failing. Possible the improved cooling helped it to work a bit longer. Here's a utility you can run to check out the drive's physical condition:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. If the drive really is failing, or is 3-5 years old, you may as well get it replaced when you get the right fan replaced.
Good luck!

Fan error and excess heat on ENVY DV6t-7200

I have a laptop-
ENVY DV6t-1200, product#B6C70AV. Windows 8.1.
The computer is only 14 months old, so it is freshly out of warranty. I have been noticing unusually loud fan noise recently. It is not consistent. Sometimes it remains loud for my entire computing session. Sometimes it quiets down after several minutes, sometimes it is not loud at all. I'd say 75% of the time, it is loud though... And the computer gets VERY hot on the bottom left side in the area of where the fan vents are located. So hot that it almost burns to the touch after about 30-45 minutes of computer usage.
Just today, after waking laptop from sleep, I had a black screen with white text stating something to the effect that "windows detected the fan is not properly cooling the computer and may result in damage, etc.." I don't remeber exact phrase. I went to try to take a screenshot by pressing windows key and prt scrn, but the message page disappeared and normal windows 8.1 start screen appeared. The computer seems to be functioning normally. But the loud noise, the strange fan warning, and the intense heat lead me to believe I have a growing problem.
ANY ideas on what I should do at this point?

Hello Andrew01,
Thank you for posting on the HP Forums!
I understand you are experiencing a "system has detected that a cooling fan is not operating properly" error. This could be a result of faulty hardware, or a recent software implication. I apologize for the inconvenience but I will do my best to assist you! To start, please follow the troubleshooting in this document: System Fan (90b) error message on startup
Although the title of the document is "System Fan (90b) error message on startup", the troubleshooting steps presented are relevant and effective. I also provided this document because I believe this is the error that you witnessed, though it's possible that is isn't the same error. If those steps do not work, here are some other suggestions to attempt: Reducing Heat Inside the PC to Prevent Overheating
If these steps do not work, the hardware is malfunctioning. I would contact HP support, to verify what your options are, or take it to a local repair shop.

Cooling fan inconsistent

I've been getting the "Cooling Fan is not operating properly" message for almost a year now, and have been saving up for a replacement fan and heatsink. Starting in about August, the fan started dying quicker, but accompanied by a grinding noise. Today, I observed the grinding sound smoothly transitioning to what I would consider a good fan speed. It happened twice in the span of an hour and hasn't happened since. Is this a problem with the fan or the heat sink unit? And do I even have to replace the full part?

Hi @EventideOne ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6b47dx Notebook and issues with the fan. Here is a document on overheating which could possible cause a fan issue or will cause the Notebook to heat up fast.
Here is a link to troubleshoot fan errors.
In the link, it has to update your BIOS, but I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings which should resolve the fan error message if cleaning does not help.
If that does not help at the end of the document it shows you to do a hardware test.
Please note remove any and all USB devices before troubleshooting. Disconnect all non-essential devices
Hope this helps.
Thanks.
