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.

System Fan(90B) error...

I bought an HP 630 Notebook PC one month ago. Now, when it's powerd on, it's showing an error message like "System Fan is not working correctly System Fan(90B)". Though my laptop is currently working but I suspect, soon it will be in trouble due to overheating and it may damage the processor. What is the permanent solution for this problem. I don't want to keep my laptop away for days. Please help me as soon as possible...

Hi there
I think you have to go for replacement cooling fan/heat-sink assembly otherwise it may damage your board, processor, card etc.
Before that please promptly follow the steps given in this document -- Cleaning vents and fans on the laptop & troubleshooting steps:

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.
