Securing Computer 42
Attaching a Strap
On the right rear side of your computer is the strap hole used to attach a strap for
preventing the computer from unexpected drop. While using the computer in tablet
mode, the attached strap is even more significant.
To hold the computer only by dragging the strap is improper and
dangerous.
