❑If the preceding step does not work, press and hold the power button for at least four seconds to turn off the power.

❑If the preceding step does not work, unplug the notebook from the AC adapter and remove the battery pack from your notebook.

❑If your notebook stops responding while playing a CD or DVD, press Ctrl+Alt+Delete and click Shut Down on the Windows Security screen to restart your notebook.

✍Pressing Ctrl+Alt+Delete simultaneously or turning off the notebook with the power switch may result in data loss in files that are currently open.
