Your laptop (HP Elitebook 840 G6) had problems during the Windows 11 upgrade. It crashed after the update and now several features, especially Video Out for the USB-C/Thunderbolt port, are not working. After using a recovery USB to return it to Windows 10, the issue persists. The Device Manager shows an I2C HID Device with code 10 and a failed HID descriptor. On another HP model, connecting the display triggers a "Generic PnP Monitor" in Bluetooth settings. I've tried various recovery drives and drivers, but nothing resolves the problem. Can someone assist in restoring this functionality?
