About power management
The Power Management setting is not responding
Your notebook’s operating system may become unstable if a lower power state, such as
Hibernate
is
initiated, and then changed before the notebook completely enters the lower power state.
To restore the notebook to its normal operating stability, proceed as follows:
1
Close all open applications.
2
Push and hold the power button for four seconds or longer to shut down the notebook.
