System Security Locking Hot Key
The default hot key option for this feature is <Ctrl> <Alt> <Backspace>, which can be changed by the
OEM through AMIBCP. When the System Password feature is enabled in WinBIOS Setup, the end user
can enable the AutoKeyLock feature at any time by pressing <Ctrl> <Alt> <Backspace>. AutoKeyLock is
used when the end user must leave the computer unattended and does not want anybody else to use it. Once
AutoKeyLock is enabled, the MEGAKEY keyboard controller accepts no keyboard or mouse input until the
correct password is entered. The Num Lock, Caps Lock, and Scroll Lock LEDs (and the Password LED if
present) blink when the system is password locked.
Indicating AutoKeyLock Status via LEDs
AutoKeyLock is indicated by the keyboard Num Lock, Caps Lock and Scroll Lock LEDs and also through
a Password LED, if present. Blinking Num Lock, Caps Lock, and Scroll Lock LEDs indicate that the
system is password locked. The Password LED also blinks if present. When the correct password is entered,
the lock is deactivated.
