A computer system may include a retractable illumination device to illuminate a keyboard in a dimly lit environment. The illumination device may be located proximal to the keyboard or on a display. The illumination device may be activated by raising it to a position above the keyboard or by exposing the device via a slideable cover. The illumination device may be deactivated by retracting it into the computer system or covering it with the slideable cover.
