Power switch and standby button

There are two controls above the keyboard that affect power in the HP notebook PC. The
switch at the top left turns computer power on and off, and the large blue button in the
top center—called the standby button—puts the system in standby mode or returns it to
normal operation.
To use the power switch
To turn the computer on, slide the power switch to the left and release it. If the computer
is plugged into AC power or contains a charged battery, the system turns on and
Windows starts automatically.
To turn the computer off, click Start, Turn Off Computer, Turn Off. Windows then shuts
down, and the computer automatically turns off. If for some reason you cannot turn the
computer off using the Start menu, you can turn it off using the power switch.
To use the standby button
You can use the blue standby button to save the current state of your computer and then
to return quickly to the same state when you are ready to resume work.
To put the computer in standby mode, press the blue standby button located above the
center of the keyboard. Pressing the standby button turns off the display and the hard
disk drive, and saves your current session to RAM. (Standby can also occur
automatically when the timeout setting is reached—see "To use automated power
management" on page 50.)
To return the computer to normal operation from standby mode, press the standby button
again. The display and the hard disk drive then turn on, and the session you were
working on earlier is restored.
Hint
If your notebook does not turn on when operating on battery power, the battery may not
be sufficiently charged. Plug in the AC adapter, then press the standby button. Keep the
adapter plugged in until your battery is charged again. (See "To check the battery
status" on page 54.)
