Coin-cell battery
Coin-cell battery provides power to the Complementary Metal‑Oxide Semiconductor (CMOS) chip while the computer is turned
off. The CMOS chip contains the time, date, and other configuration information about your computer. Under normal usage
conditions, the coin-cell battery can last for several years. Factors affecting the coin‑cell battery life are the type of system
board, temperature, the time for which the computer is powered off, and so on.
Touchpad
A touchpad is available on most laptops and provides the functionality of a mouse. It has a touch-sensitive surface that senses
the motion and position of your fingers. You can use the touchpad to move the cursor, drag or move selected items, and click
by tapping the surface. Gesture‑enabled touchpads support gestures such as zoom, pinch, rotate, scroll, and so on. You can also
purchase external touchpads. A precision touchpad is a new class of input device that provides high precision pointer input and
gesture functionality. Precision touchpads interact with the operating system directly without the need for a driver.
NOTE: For more information, see Using your touchpad.
Display
Displays are classified according to their screen size, resolution, color gamut, and so on. Generally, a screen with higher
resolution and better color support provides better image quality. Some external displays also have USB ports, media-card
readers, and so on. Displays may also support features such as, touch screen, 3D, and wireless connection.
Touch screen
Touch screen is a display device that lets you interact with the objects on the screen by touching the display instead of using
a mouse, touch pad, or a keyboard. You can operate a touch screen with a finger, or another passive object, such as a stylus.
Touch screens are commonly used in phones, tablets, computers, and so on. Commonly used touch screen technologies are
capacitive touch and resistive touch.
NOTE: Touch screen may not be supported on all computers.
NOTE: For more information, see Using your touch screen.
3D
3D-capable displays can display 3D images and videos. 3D works by presenting separate 2D images to the left and right eye.
These images are combined and interpreted by the brain as one image with depth.
NOTE: You may need specially designed 3D glasses to view 3D images.
