There is a button on the right side on the place where the screen interlocks with the keyboard. It is a circular button that lights up when you press it. It is the button behind where you plug it in to charge.
Turn the Lights On was created in 1999.

When you buy lights in the igloo catalog, they sometimes don't show up as being turned on. If you click on the light you're trying to turn on and press the "up" button on the keyboard (the arrow), the light should turn on. You can do this with other objects too, except instead of turning on lights it can make the item look different. (ex.- if you buy a fridge and press up, the fridge opens.)
you click on the lights and they will turn on.
you have to press the down arrow on your keyboard

You don't usually have to turn off the "mouse and keyboard" at all. On some models of the mac, the power button was on the keyboard, but pressing it starts the computer, it doesn't turn off the keyboard. If you have a wireless keyboard/mouse, then if you don't turn them off they're still running on battery power. The batteries won't last as long if you don't shut them off, but you don't HAVE to do it.
the multifunction switch... ( turn signal) twist it to turn on the lights and once the lights are on pull it towards the door to turn the fog lights on
The modern PC keyboard includes a control processor and indicator lights to provide feedback to the user about what state the keyboard is in. Depending on the sophistication of the controller's programming, the keyboard may also offer other special features. The processor is usually a single chip 8048 microcontroller variant. The keyboard switch matrix is wired to its inputs and it processes the incoming keystrokes and sends the results down a serial cable (the keyboard cord) to a receiver in the main computer box. It also controls the illumination of the "caps lock", "num lock" and "scroll lock" lights. A common test for whether the computer has crashed is pressing the "caps lock" key. The keyboard sends the key code to the keyboard driver running in the main computer; if the main computer is operating, it commands the light to turn on. All the other indicator lights work in a similar way. The keyboard driver also tracks the shift, alt and control state of the keyboard.
