5Turn the computer over and restart it.
TECHNICAL NOTE: You must have at least one memory
module installed for the computer to work.

Checking total memory

When you add or remove a memory module, you can check
that the computer has recognized the change. To do this:
1Click Start, Control Panel, Performance and
Maintenance, and then System.
2The General tab view automatically appears and shows
total memory.
If the computer does not recognize the memory
configuration, turn off the computer, remove the memory slot
cover, and make sure the memory module is seated properly,
as described in step 13 of “Installing a memory module” on
page 56.
Connecting an external USB mouse
You may want to use a mouse instead of the TouchPad, the
computer’s built-in pointing device. You can attach an
external mouse to one of the computer’s USB ports, provided
the mouse is USB-compatible.
To connect the mouse, or any other USB device to your
computer, plug its cable into one of the USB ports. You can
connect it while the computer is on.
