palm rest works as a system status indicator: it shows whether the computer is in sleep
(standby), hibernation, or normal mode.
• Red: The computer is on (in normal mode).
• Fast blinking red: The computer is entering sleep (standby) or hibernation mode.
• Slow blinking red: The computer is in sleep (standby) mode.
• Off: The computer is off or in hibernation mode.
