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 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...

Hi there
I think you have to go for replacement cooling fan/heat-sink assembly otherwise it may damage your board, processor, card etc.

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.

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.

Pavilion dv7-4060us Color Printing Problems...

I just bought a new Pavilion dv7-4060us Notebook and am having problems printing in color. I have a Xerox Phaser 8550DP PS Printer that I'm trying to connect to through a wireless network connection. I can find the printer on the network and install the "Xerox Phaser 8550DP PS" driver online just fine. But, after all that, when I try to print, it will only print in Black and White. For some reason it just will not print in color. I've looked through all my "printer properties" and it doesn't even show color options! It's like my computer just doesn't even recognize that the printer can print colors. Like maybe that printer's driver is for some reason not recognizing it as that actual printer?!
I tried deleting the printer and the driver off my computer and installing it using the printer's original CD, but it says it's not compatible with Windows 7 OS. But installing the driver via online and using the CD should basically be the same thing shouldn't it? So that can't be the problem. The "HP printer help website" doesn't really help at all because it's a Xerox printer and not an HP. After reading through some forum posts I figured maybe it was a firewall problem, but wouldn't the firewall stop me from printing all together...not just prevent me from printing color?
Has anyone seen this happen before or heard of anything like this happening? Right when I got the computer I kind of went through and deleted a few things I thought were Crapware, so the only thing I can think of right now is that maybe I accidentally deleted some kind of software program that lets me print color?! Which doesn't really make any sense, so I don't think that's it.
Also, I know it's not a Windows 7 OS problem or my wireless connection because my brother's computer uses Windows 7 and connects through wireless as well, but his can print color just fine. He set his computer up like a year ago so he can't remember how he set it all up or what he did, so he's kind of useless.
As of right now the only thing I can think of to do is try posting on this HP help forum and post on the Xerox Printer help forum and see if anyone has any advice for me. If you have any ideas I'm up for trying anything because I pretty much NEED to be able to print from this computer!! Any information can help out a lot so just let me know. Thanks!

I have exactly the same problem with my dv7-4171us, my husband has the same printer and it print fine on my Xerox but mine only prints in black and white, its very frustrating. I called HP and after 2 hours on the phone they couldnt fix it either.
I'm thinking of doing a full "f11" factory restore. If anyone knows how to fix the color printing problem please let me know.

When i turned on my notebook a message indicated that a system fan (90b) was not operating correctly

When I turn on my HP Pavilion G7 - running Windows 7 - notebook an error screen comes on saying that a system fan is not working with what seems like an error code of 90B. I can continue through to startup normally, but the message indicates that it may cause malfunctions to do so. How do I resolve this problem?

Try to use a can of compressed air in the reverse direction of the normal air flow with the computer off. A dust/lint/hair matt can accumulate on the inside of the heatsink near the fan blades.

How to increase fan speed on HP pavilion dv7

i have a major problem with my fans on my pc. It often reaches 80-90 degrees celcuis, when i have been playing a fairly simple game for about 20 minutes. does anyone know what to do? and it dosent seem like i can increase my fan speed in any way. i have been trying almost everything i can find on the internet. please help

Hello themanafreak. I understand your notebook is getting warm during use.
First, you should ensure that the cooling system of the notebook is free of dust and debris but cleaning the notebook as per these instructions.
Also, another good step to take is to ensure that you have the latest version of the BIOS installed. I can locate the latest BIOS for you if you provide me with your product number. This document can show you where the product number is located. Finally, I do not know of a way to increase the fan's speed itself but you can set the fan to "always be on" by doing the following.
Reboot your computer and press F10 until the BIOS loads.Navigate to the System Configuration section.Ensure that "Fan Always On" is set to enabled.Navigate to the Exit section and save your changes.
Have a great day!

'Cooling fan is not operating correctly' - System Fan (90B) - HP Envy 14 2002ea

Hi
I just bought this laptop off of someone and am having this error appear at startup. It only appears on fresh startup, not if I restart.
I can hear the fan working and it's not particularly noisy, although it is on continuously. Is this normal? I also have an Envy 14 1050ea and the fan in that is running quieter and also definitely cooler. Although the Envy 1050ea is i5 and the 2002ea is i7.
I thought it might need a BIOS uprade for the 2002ea but turns out the latest is already installed (F.0F).
Has anyone else had and/or managed to rectify this problem? Don't really want my laptop to melt on me...
Thanks

Try a hard reset. Remove battery and AC plug; hold down power button 30 seconds. Wait 30 seconds. Plug in AC. Power on. Also try going into the BIOS (F10) and reset to default settings. Lastly take a bent-out paperclip and stick it in the fan grille to hold it from spinning out of control. Now blow in some strong compressed air. If none of this works, the fan needs to be replaced. The part is cheap but it requires significant disassembly.

HP pavilion dv7 4060us

So i tried to clean my dv 4060us's screen with window cleaner but it went down to the place when the screen connects to the laptop and now i can's see the right side of the screen (exactly the 1/3 of the screen is white and nothing else) the center 1/3 of the screen is perfect and the left side is good but a bit dim. So what could be the problem? It was about a week ago, so it should be dry. Should i buy a new screen or only the cable wrong?
Many thanks! I have connected to a monitor so i can use it, but not movable!

what kind of window cleaner...not windex with ammonia I hope

How to fix "unmountable_boot_volume" blue screen error on Pavilion dv7 2185 dx notebook

I turned on the laptop and it would only show the blue screen for a second and then cut off. I tried F7, F8, F9, F10, F11 and nothing seems to work. I tried starting it in the last good sector. I tried fixing it and nothing seems to work.
The blue screen also says - disable memory option (caching/shadowing).
I bought this latptop with the original Vista OS but I later received the Window 7 upgrade through HP. This laptop did not come with recovery CDs.
Does anyone know what I can do to fix the problem? Please help me

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.
