Laptopfan dv7-6c17ez (90b error)

Hey,
Everytime I turn my laptop on I get this 90b error message, saying that the fan of my laptop doesn't work properly. Sometimes the fan rotates and I can use the laptop without any difficulties and sometimes it just doesn't and my laptop overheats whenever I'm playing videogames.
One of my friends is an IT-specialist and is looking to replace the fan for me.
Could anyone tell me the model of the fan of a dv7-6c17ez? If you know other solutions to this problem please let me know.
Thanks in advance,
CR_

This could be bad fan OR motherboard related problem. You will not know untill the fan is replaced. If the problem is still there, it's the motherboard.
The fan is mounted deep inside the laptop and it's necessary to remove the motherboard in order to access the fan.
You can find a replacment fan on eBay or Amazon.
Here's an example of accessing cooling fan in a HP Pavilion dv7-6000 series notebook.
Show it to your fried. Is he ready for this repair?

System Fan (90B) Error / HP Pavilion dv7-4060us

Hi. I have a Pavilion dv7-4060us notebook, Windows 7 Home Premium, 64-bit. I had an overheating problem not too long ago that caused my notebook to shut down on it's own. I bought a cooling pad to help with the overheating, which helped. But now, everytime I start up, it gives me a black screen reading "Operating System has found that a cooling fan has stopped working" or something similar. The error code was "System Fan (90B)." How do I get rid of this error message? Post back here or reach my email at [email protected] Thanks.
This question was solved.
View Solution.

This PreBoot Diagnostics that is indicating there is an issue with system fan. It would be a case of System Fan not running or running at slower speed than it should...
I would suggest, try doing power drain, by disconecting AC adapter, removing battery and pressing the power button for few secs... if that always you to boot to the OS, that Update the BIOS if not than I would suggest contacting HP Tech Support for getting your unit serviced...

System Fan 90B Error Message

Hello, I've had my Envy dv7-7320us for about 2-3 years and Just last week my notebook shut itself off in the middle of me working on it. When I turned it back on, there was a black screen that read ...... The System Fan <90B> message that everyone here seems to be getting. I sent it over to a computer shop and they cleaned the fan (it was filthy), and I also gave to ok to replace the fan. So they did that as well. Here we are into the 7th day since the error page occured and the shop tells me that the message STILL appears , even after cleaning and replacing the fan. I dont want them to do anything more , because it sounds like things might get costly and if it's something that I can do myself, I would prefer to just do so. Does anyone know why the message could still be appearing , or what other methods I can take to resolve this problem? I just dont want them to do anything drastic or costly for no reason. PLEASE HELP!!

Some bios's have a error message section that needs to be cleared before the message will stop. If not try clearing the cmos by removing the cmos battery for 15 minutes.

Dv7 6b32us HDD error 301

I have a dv7 6b32us . I ran HDD test and error 301 came up on both quick test and long test. Does this mean I have to replace it? Any recommendation for the new HDD replacement?

Hi,
Yes, it does look like you'll need to replace the HDD.
The drive on the link below is an example of one that would be fine for your notebook.
750Gb Notebook Hard Drive.
The procedure to replace the Hard Drive starts on Page 59 of your Maintenance & Service Guide.

HP Pavilion dv7-4269wm SMART Error and Recovery

My hard drive recently crashed after receving SMART errors for over 6 months. I am planning on ordering a new hard drive to replace it. Thankfully I was able to backup my computer about 2 weeks ago so I dont think I lost anything important. My question is regarding the recovery discs from HP. Although I am from the US, I am in the Netherlands Antilles at the moment and am having a hard time contacting an HP office to mail me the recovery discs. If I install a new hard drive and install Windows on my computer, is it necessary to have the recovery discs to make sure all the drivers, etc. are working or will my computer still work properly without them?

How are you planning to reinstall operating system?
To confirm the fail, do the hard drive - quick & extensive test from BIOS - System Diagnostics by pressing ESC key or F10 as soon as you power on the laptop.
If that fail & generate 24-character failure ID, is a hardware failure & replacement if the option left.
You can use Recovery media only if you buy & install a new HDD of capacity 750gb or higher.
For clean installation, that's not an issue.
You can download & save all the latest version of the drivers (check the date & version number) setup/.exe files in to USB. Insert USB & DVD simultaneously and there'll be option for loading driver during process of installation, just select the USB from there & it'll automatically install the storage drivers from it.
Later on after Windows installation, additional drivers could be installed from USB manually with a restart of notebook after each installation.

Overheating issue - 90b error

Good evening, Since I bought my HP laptop I've had the overheating problem that I know is familiar to most HP users. My computer usually sounds like a helicopter and when running some more demanding programs, or even if it's just a hot day and I'm watching a video, it shuts down. Today I went to clean it up, following the usual advice of blowing air through the openings on the side and underneath, and when I came home and turned it on, the computer went down really fast and when turning it back on, this message showed up: The system has detected that a cooling fan is not operating correctly.Continued operation is not recommended and may cause unpredictable behavior that could result in random shutdown, data loss or possible system damage. The system will shut down in 15 seconds. To prevent shutdown and continue operation, press the Enter key now.System Fan (90b) This isn't the usual message I get when the computer overheats, also, for the first time since I took it out the store 4 years ago, it was dead silent. Can somebody please help me understand what happened and how can I fix it? Thank you so much in advance, I'll really appreciate your help

If you will provide the complete product number I can find that for you. It also depends on how your notebook is configured. Is your notebook one with a discrete graphics module or an interated builtin Intel or AMD graphics solution?
1. The full Model No. and Product No. of the notebook - see This HP web document if you don't how to locate the model number and\or product number.

Hi @CatsRcool
Welcome to the HP Support Forums! I saw your post regarding the problem with the fan. You are going to have to open up the notebook to replace the fan or you can take it to a local technician. If you want to do it yourself here is the Maintenance and Service Guide for your model. On page 75 you will find the part number for the fan and instructions on removing the heat sink assembly which the fan is apart of.

Error 90B - Fan not working properly?

Hello, this is my first time here so please excuse me if I posted this in the wrong section.
First, general specs:
HP Pavilion dv6 Notebook PC
Windows 7 Home Premium 64-Bit
BIOS: InsydeH20 Version CCB.03.61.09F.21
Processor: AMD A6-3400M APU w/Radeon HD (4 cpus ~1.4GHz)
6g RAM
(If anything else is needed to help me ask, and I shall post it)
Last week I received an error 90B for my laptop's cooling fan. I was playing Guild Wars 2 and in the middle of playing my laptop shut down suddenly. When I turned it back on it presented the error I'm asking about. The thing is, the system wasn't overheating in the slightest and the fan was working just fine before it shut down. I've tried many fixes proposed on HP's website and from a couple of friends:
-Compressed air blown into the vents
-System restore to a point where the fan worked
-Hard reset
-BIOS update
None of those proposed fixes worked. However, I did find something that fixed it...for about ten minutes. I fiddled with the Catalyst Control Center and set my CPU power back to its default 1400 MHz, and I shut down my system. After I restarted it I miraculously didn't get the 90b error! You could imagine how happy I was. I shut it down one more time to see if the error was truly fixed, but lo and behold it showed up again.
The only change that could have caused the issue was me downloading a program called SpeedFan to monitor my system's temperature (I did NOT (I repeat, DID NOT) change any settings using the program - I purely used it to monitor the temperature.)
I cannot afford to have a repairman replace or look at my laptop as of now, we have bills to pay and food to get, and I absolutely NEED this computer to function. I have work to do, and classes to sign up for, and we have no public computers for miles. Please help me!

Not every fan error is a heat error. There is a sensor that detects a bearing that is wearing out or spinning that is out of round. You can sometimes limp it along for 6 months before the fan absolutely has to be replaced. When it does you will not be able to get past the error.

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.

That means battery getting used but notebook not getting understand and giving me battery low alarm. Then i have to remove battery and insert it again. it will work for 2-3 days n then same problem repeat.
( pl note that note book battery is good and giving 2-3 hours backup when fully charge)
Both my problem was chronic so i took photograph when problem came and then given laptop for repair at service centre as it was under warranty.
Then next day i received call from service centre that my laptop ok pl come and collect. so i went to service centre when i checked found same problem so they took back and said motherboard is faulty.

or any government intervention is required ?

Hello @yoursviru ,
Welcome to the HP Forums!
I understand you have issues with charging and a 90b fan error on startup.
To address your question about a trial period after repair: Typically the repairs should include a 90 day service warranty or the remainder of your existing warranty whichever is greater. This depends if the repair was done by HP or an authorized HP provider. HP Phone Support can confirm this for you.
If the repair was not done by HP or an HP service provider HP cannot guarantee the work of third party companies.
The power not charging the notebook could be an issue with the battery, internal power connector cable, power adapter, or motherboard. All of which are hardware related.
You can read about the fan error here and what to do to fix it: System Fan (90b) error message on startup.
To sum everything up. I suggest you get in touch with HP Phone Support as soon as possible as they are the ones who can give you a straight answer regarding service and warranty questions. My answers are based on personal experiences, as the forums do not offer service and are available regardless of the warranty status.
Hopefully Phone Support can give you the answers you're looking for.

Another 90b failure - new notebook

I purchased a new Probook 450 g1 just under a month ago. Last week, I started getting the 90b error.
I've cleaned the fan - it wasn't dirty as the machine is new.
I verified the fan is running and blowing warm air.
I did the hard reset.
I did a BIOS update. That fixed it for a few days.
This actually only seems to happen after a session where the fan needs to run hard, such as doing a video render or playing a game - but when it starts, it does it pretty much continually.
I find it hard to believe my new machine could be failing already, especially considering this seems to be a constant problem. Is there any other troubleshooting steps I need to take before returning it for a refund?

Yes it will work and don’t need to use that easy button. On this laptop when you go to Wireless Network Connection and select View Available Wireless Connection, you may be able to see your network select that and say connect. It may need to provide the wireless key if you have any.
