Getting to Know the Computer
Front View
Screen
-
Your portable computer has a 25-line electroluminescent and
liquid crystal display (LCD) that's compatible with the IBM PC® color
graphics adapter in text and graphics modes.
The display has a back light, which you adjust to control the display inten­
sity. When the computer is on and a key has not been pressed for 10
minutes, the back light automatically goes off, thus prolonging the life
of the internal battery. Pressing any key will turn the back light on again.
Cursor
-
When you're using MS-DOS® (the operating system), you'll
notice a rectangular block on the screen. This is the cursor and it marks
the position where your typed entries will appear. You'll also see the cursor
on the screen when you run most programs, and when you type, and
position text. It also has other duties with some of the portable's built-in
functions.
