HP pavilion dv6 fan not working

My HP PAVILIONDV6T-6100 laptop (Product no. LM720AV) is having problems with the cooling fan and overheating. I have started getting the cooling fan not functioning error at startup. When I use the laptop-the cooling fan runs almost all the time. It turns-off when I have only one application running on the laptop.
I understand that since the fan is running perfectly fine, the fan motor is still functional. Could it be dust accumulation that is causing the error and fan running continuously? Where can I get the insturctions for opening the cooling fan assembly and cleaning it? Also will I need to replace the thermal insulation after cleaning?
Thanks
Sunny

I paid $30,000 for my car but I trust the dealer to work on it because I know their mechanics do it every day. I could watch youtube videos and figure out how to do a tuneup but they will do it better. I will change my own air filter however since it is not too hard and will save money. Replacing a cooling fan is more like a tuneup than replacing an air filter. Still, you can do it if you follow the Manual and are careful. Here is the Manual:

I would go ahead and run all the diagnostic tests you can access by tapping F2 and entering UEFI Diagnostics. Other than the fan what other problems are you having?

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:

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.

Pavilion dv6 mousepad not working

My laptop operates on windows 7, 64 bit.
The mousepad has stopped working and there are no lights displaying on the pad.

Thank you for your post, I will do my best to help.
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 grasp that the Touchpad has stopped responding and it is not lit. Here is a link to Using and Configuring the TouchPad (Windows 7 and Vista) that may help. Was it perhaps, accidently disabled?
You can run diagnostics to test the Touchpad for failure. On startup press F2 approximately once every second to display the diagnostic screen. About UEFI and the Startup Menu.
You can also run MS Fix It to help resolve issues. The HP Support Assistant can also help to fix issues and look for updates.
If you would like further assistance, would you please provide the exact model of pavilion dv6 you have? How Do I Find My Model Number or Product Number?

Pavilion dv6 Webcam not working?

I have a Pavilion dv6-1030ca notebook, and for the past few weeks, I've been having trouble with my webcam. When I open HP MediaSmart Webcam, I get the following error message: "No video device detected. Please plug a video device into your computer. If you are using an integrated camera please make sure it is turned on." I have an integrated camera, and it (usually) turns on when the webcam application opens. I am running Windows Vista with SP1, and have tried many things to fix it, to no avail. The webcam does not appear in Device Manager, under Imaging Devices nor any of the USB Root Hubs. So far, I have attempted to:
- Reinstalled the USB Root Hub Drivers
- Tried to fix the solution in BIOS (as another thread suggested)
- Attempted to use Recovery Manager to reinstall the driver (was not in the list)
- Created Recovery Disks to solve the problem (it didn't)
- Upgraded the MediaSmart Webcam software
I am in school right now, and I really can't afford to give my laptop away to get repaired for three weeks since I have exams coming up. Any help would be appreciated! Thanks!

This question was solved.
View Solution.

I am in the exact boat as you.
Couldn't understand why all of a sudden, after about 3 months, the webcam 'device not found' in Win7 Device Manager, Google Chat, Skype, etc.
Called HP support, and they made us do a hard reset of the entire notebook, removing the battery, ac cord, and holding down the power button for 1 minute.
Webcam came back for 1 day, but I'm not about to unplug and reset everytime I am in the middle of a skype call?!
Sadly, HP or Costco (where it was purchased) doesn't seem to care or are willing to provide a solution.
Instead of recalling the computers, like automobile and other industries, they just wait and hope that the warranty runs out before it becomes a big deal.
They didn't stop selling them either, even with this known problem.
So now they have the G series of notebooks, and so the dv6 and its headaches can fade away for HP.
I have probably been involved with over 100 HP product purchases in my job the past 5 years, but this will be the last for the forseeable future.

Horrible fps problems, fans not working

Hi,
Whenever I play League of Legends on my 15 inch retina macbook pro, the game starts out smoothly with a consistent 60 fps. However, after a certain period of time, the fps severely drops to about 5. It never used to do this, but now it happens consistently. Also, the fans have not turned on in months; they used to always be on whenever I played League, but they seem to never turn on anymore. Could the fps problem be related to the fan not working? Please help, and thanks!
