Your notebook's operating system may become unstable if it is interrupted or if
you attempt to make changes before the notebook completely enters a lower
power state, such as Hibernate.

2 Restart the notebook by pressing Ctrl+Alt+Delete simultaneously and
selecting Restart from the drop-down list.
