￿	Do not scratch the LCD or exert pressure on it. This could cause malfunction.
￿	Using the computer in low temperature conditions may produce a residual image
	on the screen. This is not a malfunction. When the computer returns to normal
	temperature, the screen returns to normal.
￿	A residual image may appear on the screen if the same image is displayed for a
	lengthy period of time. The residual image disappears in a while. You can use a
	screen saver to prevent residual images.
￿	The screen becomes warm during operation. This is normal and does not indicate
	a malfunction.
￿	The LCD is manufactured using high-precision technology. You may, however, see
	tiny black points and/or bright points (red, blue, or green) that continuously
	appear on the LCD. This is a normal result of the manufacturing process and does
	not indicate a malfunction.
On the power source
￿	Your computer operates on 100V-240V AC 50/60 Hz.
￿	Do not share the AC outlet with other power-consuming equipment, such as a
	copying machine or shredder.
￿	You can purchase a power strip with a surge protector. This device prevents
	damage to your computer caused by sudden power surges such as those that may
	occur during an electrical storm.
￿	Do not place heavy objects on the power cord.
￿	To disconnect the cord, pull it out by the plug. Never pull the cord itself.
￿	Unplug your computer from the wall outlet if you will not be using the computer
	for a long time.
￿	When the AC adapter is not used, unplug it from the AC outlet.
￿	Use only the AC adapter supplied. Do not use any other AC adapter.
