unexpected actions, and for tablet mode, the power key is not accessible. To solve this problem, a second
security power key which is integrated into keyboard design is proposed, to avoid the accidently usage
through the normal working both clamshell and tablet mode. The second key is more security to ensure the
device is working on safe state, the implementation both hardware and electrical design is illustrated.
