Introducing the PC

If the PC stops responding, use the Windows Task Manager to close any
programs not responding or to restart the PC:
1 Press the Ctrl, Alt, and Delete keys on the keyboard at the same time.
2 Select the program that is not responding, and click End Task.
Or
Click Shut Down, and then click Restart.
If this does not work, press the On button for 5 or more seconds to turn off the PC.
Then, press the On button.
NOTE: Using the On button to restart the PC is not recommended and should be
used only as a last resort. Instead, click Start, click Turn Off Computer, and
then click Restart.
Using the Mouse
Your PC includes a mouse for directing the cursor (pointer) on the Windows
desktop. The mouse uses a roller ball or optics (a light and sensor) to sense
movement and cause the cursor on the screen to move. Use the mouse on a
flat surface.
NOTE: The optical mouse cannot work on a glass, translucent or reflective surface.
A wireless mouse (select models only) is an optical mouse that uses a
receiver/transmitter, instead of a connector cable, to communicate with your PC.
A light on the receiver indicates receiver activity.
NOTE: The wireless mouse goes into a sleep or suspend mode after 20 minutes of
inactivity. Click a button on the mouse to wake it. (Moving the wireless mouse
does not wake it.)
Using the Mouse Buttons
The mouse has two or three buttons on the top:
• Click the left mouse button to position the cursor or to select an item.
• Click the right mouse button to display a menu of commands for the item
you clicked.
• On select models, use the scroll wheel button in the centre for scrolling
and panning.
