System Fan Error 90b, blue screen
The system has detected that a cooling fan is not operating correctly
Continued operation of the computer is not recommended by HP and might
cause unpredictable behavior that can result in a shutdown, data loss, or
computer damage. The computer will shut down in 15 seconds. To prevent
the shutdown and continue operation, press ENTER key now.
for more info go to www.hp.com/go/90Xfanerror.
I went to the website and followed the steps 1-4 (4 being the hard reset) and that did not work to fix the issue.
I contacted HP Support Assist in hopes of fixing this without having to have it serviced, I bought this laptop around 9 months ago.
thank you for your help

Hi @Gizmo0620, Welcome to the HP Support Community.
Apologies for all the inconvenience
Don't worry as I'll be glad to help,
I appreciate your efforts to try and resolve the issue, and in order to fix this issue, your computer needs to be serviced. As we have limited support boundaries in the support community as of now,
As this is a hardware issue, I'd suggest youContact HPin your region regarding the service options for your computer.
If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.
Have a great day!

@Gizmo0620 -- have you tried: HP PCs - 900, 909, 90A, 90B, 90F Error Displays on a Black Screen | HP® Customer Support
Or, power-off the computer. Remove the battery. Disconnect the AC power. Hold-down the ON/OFF button for 5 seconds. Reconnect the battery. Reconnect the AC power. Restart. Does this work?
