Synchronizing a tablet and keyboard (select products only)
For a tablet with a detachable keyboard, when you attach the tablet to the keyboard and restart the
computer, Setup Utility (BIOS) checks to see if the Embedded Controller firmware on the keyboard needs to be
synchronized. If so, synchronization begins. If the synchronization is interrupted, a notification screen
