I have an Inspiron 14 (5410) running Windows 11.  Lately, I'm unable to use the Windows "shut down" option to power down the laptop. Instead, the laptop simply goes back to the initial login screen. Even from the login screen, if I pick the "shut down" option, the laptop will just keep cycling back to the login screen.  If I close the laptop lid, it seems the laptop is still consuming power and does not shut down. So if I leave the charger off, in a few hours, the laptop will run out of power and die. How can I get the laptop to power down as intended? Just FYI, this worked fine when the laptop was first purchased... seems some firmware or Windows update may have broken this.
