Cooling fans not running anymore at all, but no error (90B) on startup?

[Jonathan_Esche]

For a while I have been getting the 90B error during startup which told me my fans weren't functioning properly, and during use I noticed they often sounded louder than they probably needed to be. So I decided to open my laptop to clean the fans from dust. I was very careful not to rip out any cables and only took out one of the fans in order to clean it more easily (using a paperclip and blowing through it myself).

Now, when starting up I don't get the error message anymore, and my fan is completely off all the time (no noise, 0 rpm according to SpeedFan). Is there any way I could try to fix this myself (without having to wait for repair shops to open up again thanks to our current COVID-19 situation)?

If the issue still persists, I'd suggest you Contact HP in 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.
