Me and several of our users have been having this problem on HP laptops with Windows 10 and 11. When trying to turn off the computer with the "Shut down" option in the Start menu, it gets stuck on "Shutting down" with the fans still running, sometimes for more than 40 minutes. The only way we've been able to properly turn them off is by pressing and holding the power button.
We've tried to fix it by installing new BIOS drivers from HP, and this solved the issue for a few days, but now this fix has stopped working for several users. We would like a more permanent solution to make sure this problem doesn't come back or cause more issues.
