Your BIOS update likely caused power-state errors. Try this:
# ***Hard reset*** (unplug, hold power 30 sec).
# ***Update touchpad drivers*** in Device Manager.
# ***Disable auto tablet mode*** in Windows Settings.
# ***Reset BIOS to defaults*** (press F2/DEL at startup).
# ***Check for newer BIOS updates*** from manufacturer.
If problems continue, contact support—you may need a BIOS rollback.
