power  is on. Never move the unit when this light is on.
*Diskette drive activity light--Turns on whenever the diskette drive is  
 reading from or writing to a diskette. Never remove a diskette when this  
 light is on.

 off  the computer and then turned it on again.
*Keylock--Locks the computer's cover in place to prevent unauthorized 
 removal of expansion adapters.
*Diskette eject button--Ejects the diskette from the drive.

CAUTION: Take a moment to record your keylock key number on the worksheet
