System-status indicators

Device Access

A hard disk drive or an optional drive, such as a drive in the Ultrabay, is being used to read or write data.

When this indicator is blinking, do not put the computer into sleep (standby) mode, remove the device from the bay, or turn off the computer.

2

Power On

The power switch stays lit whenever the computer is on, blinks when the computer is in sleep (standby) mode, and is off when the computer is off.

Caps Lock

Caps Lock mode is enabled. You can enter all alphabetic characters (A-Z) in uppercase without pressing the Shift key.

4

Numeric lock

By default, when the numeric lock is on, the numeric lock indicator is displayed on the screen. To change the settings of the numeric lock indicator, see “Changing display settings” on page 77.

Note: Another mode available for your computer, though there is no indicator for it, is Scroll Lock mode. When this mode is enabled, the arrow keys can be used as function keys for screen-scrolling, but not for moving the cursor. To enable or disable this mode, press ScrLk. Not all application programs support this function.
