If your computer continues to display the message “Operating system not found,”

CD(s)” on page 40 for more information.
Why does my computer stop responding or won’t turn off?
It is best to turn off your computer using the Turn Off Computer command on the
Windows Start menu. Using other methods, including those listed below, may
result in loss of unsaved data.
❑ Click Start on the Windows® taskbar, select Turn Off Computer, and then
click Turn Off.
❑ If your computer does not turn off, press Ctrl+Alt+Delete simultaneously.
When the Windows Task Manager dialog box appears, click Turn Off
from the Shut Down menu.
❑ If your computer still does not turn off, press and hold the power button for
at least four seconds to turn off the power.
❑ Unplug the computer from the AC adapter, and remove the battery from
your computer.
❑ If your computer stops responding while playing a CD or DVD, press
Ctrl+Alt+Delete simultaneously. You can turn off the computer from the
Shut Down menu.
Why won’t the power management respond?
Your computer’s operating system may become unstable if a lower power state,
such as Hibernate, is initiated and changed before the computer completely
enters the lower power state.
The System Recovery CD restores your computer to its original state, so user
data and applications will be lost.
✍
Pressing the Ctrl+Alt+Delete keys simultaneously or turning off the computer with the
power button may result in data loss in files that are currently open.
