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.

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 / 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.

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 @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.

Material- chapter ID is not maintained system should give error message

Dear All
Requirement is as that while creating the sale order & if the material- chapter id is not maintained then system should give error message saying that the combination is not maintained.
Client is using the TAXINN procedure.
I think in TAXINJ it works well.
Whether it can be done in TAXINN also through SD Module itself.cleint is using the automatic creation of excise invoice.
Kindly help .
with regards
Rohit

hi rohit,
For TAXINN procedure system will not throw it as an error.
if you want it to throw:
use MV45AFZZ : USEREXIT_SAVE_DOCUMENT.
say your SAP system to compare and check for the values in J_1IVCHID-J_1ICHID
if it is not equal to.
then throw an ERROR message against it when saving the document.

Control.invoke() throws System.ArgumentException with Error message as 'Parameter is not valid'

Hi All,
While doing cross thread communication, i am getting System.ArgumentException with Error message as 'Parameter is not valid' when call is made on the control.invoke(delegate method, parama object[]).
I have checked the parameters, all parameters look good.
Please share your views on this.

I am going to explain the following Exception schenario.
The RenderForm() is called from different thread and initially panel.InvokeRequired is true as it gets called from different thread and then invoke() gets called.
So again same method is getting called and InvokeRequired property has then changedd to false and then else part of the code is executed however if i call the RenderForm() repetadely then application throws the exception as stem.ArgumentException with Error
message as 'Parameter is not valid'
And the Exception stack trace is as below-
Type: System.ArgumentException
Message: Parameter is not valid.

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.

System Tray Status Error Message

HP CP1025nw. XP. with USB connection. Printer works fine, but gives error message on screen, "HP Systems Tray has encountered a problem and needs to close. We are sorry for the inconvienience." "Please tell Microsoft about this problem. (send or Don't send)"
I get 2 copies of this error message (one at a time) wnen the computer is booted up (even if the printer off and USB unplugged) and 2 copies in addition for each "print command" from all various application sources. The printer works fine and prints are fine and there no functional issues. If the driver is uninstalled, then there are no error messages at boot-up. Latest HP driver is installed, same problem as with driver on OEM disc.
(a screen copy of error message is avialable)
Ronpro

Hi Ronpro,
Welcome to the HP Forums.
I see that you are getting a message "HP Systems Tray has encountered a problem and needs to close. We are sorry for the inconvienience." "Please tell Microsoft about this problem".
I will be happy to help you.
I believe the error is for the HP Device Settings options for the printer maintenance located on the Windows system tray.
I would run a full uninstall and reinstall. Turn off any startup programs interfering and temporarily turn off the Antivirus Software to get the full software installed properly.
Disconnect the USB cable first.
Uninstalling the Printer Software.
I would disable all the start up programs to make sure something in the background isn't causing any issues.
Go to start, run, type in msconfig, click the Services tab.
Click to select the Hide All Microsoft Services check box.
Click Disable All, and then click OK.
Click on the start up tab across the top, select disable all, apply, OK and restart the computer.
Temporarily turn off the Antivirus software.
Then reinstall the printer software again.
Full Feature Software and Driver.
Test the printer.
Check to see if the Device Settings feature will now open.
Cleaning the Paper Path and Exterior.
Restart the computer to see if the error comes up again.
Then go back in and enable the startup programs and Microsoft services and turn the Anitivirus software back on.
If the issue comes back after turning on the startup programs, I would leave everything unchecked except the Antivirus Software.
Please let me know if you need further assistance.
Thank you for posting on the HP Forums.
Have a great day.

Filters Won't Work in CS3 - Get "file system I/O error" message

Using CS3 on Mac G5, OS 10.4, and some Photoshop filters (e.g. Liquify) won't open, getting the message: "A file system I/O error has occurred."
Some filters do open, but others fail.
Have tried reinstalling CS3, trashing preferences, unlocked permissions - no help.
Any suggestions?

Peter,
The very instant you create a new document or open an existing image file, Photoshop creates a Scratch Disk to use as virtual memory, regardless of how much RAM you have installed. This scratch disk is created on whichever drive you have designated as your PRIMARY disk drive. If it happens to be on your boot drive, i.e. the drive where your OS (Operating System) resides, it will be competing with the OS swap file for use of the one read head on that disk. Very bad for performance.
Ideally, it should be a dedicated, separate internal hard drive, Figure on at least 35 times or more the size of your largest file for scratch. I keep a dedicated 160GB internal drive as my primary scratch disk.
You should not be running a G5 with less than 4GB of installed RAM. 512 MB would be ludicrous, but even 1GB is pathetic little RAM.
I agree that your hard drive sounds like it's going south. Get two new, large hard drives, at least 250GB each.
