Password
When you select this icon, the following screen is displayed.
Power-On Password: Setting a power-on password helps protect information stored
in your computer. If a power-on password is set for your computer, the Power On
icon is shown in the locked position; if a power-on password is not set, then the
Power On icon is shown in the unlocked position (as in the screen above).
When you select the Entry icon, a screen with 8 empty boxes appears. Type your
password in these boxes. You can use any combination of up to eight characters
(A–Z, a–z, and 0–9) for your password. As you type a character, a key appears in
the box.
