Password Problems If you set a power-on password using the Setup program, you must enter this password after you turn on your computer before you can use the system. When you turn on the computer, the screen displays a key prompt ( 9rn ). If you do not enter the correct password, you see an x on the screen to indicate it is incorrect. The computer gives you a second and third chance to enter it correctly. If after three tries you have not entered the correct password, the computer locks up and does not respond to your keyboard entries. Try the following: 1. If you think you know the correct password, reset the computer and try again. (You'll get three chances, as before, to enter the correct password.) See Chapter 3 for instructions on using the password. 2. If you do not know the power-on password and cannot access your computer, you need to disable the password function by setting jumper number 1 (J1) on the main system board inside the computer to position B. See "Changing Jumper Settings" in Chapter 5 for instructions. If you disable the password function, the computer loads MS-DOS and does not request a power-on password when you turn it on. 3. If you do not know the current power-on password and you want to set a new one, perform the following procedures in the order listed here: Cl Follow the instructions in "Changing Jumper Settings" in Chapter 5 to disable the password function by setting jumper J1 to position B. Cl Turn on the computer, wait at least five seconds, and then turn it off. A-4 Troubleshooting
