NOTE: The security cable is designed to act as a deterrent, but
it may not prevent the computer from being mishandled or
stolen.

internal components and prevent overheating. It is normal for
the internal fan to cycle on and off during routine operation.

cell phones and MP3 players, even when the computer is off.
