Why Does the Power Button on My Desktop Computer Change Colors or Blink

Meanings of Power Button States

Dell desktop computers have a power button light (LED) that is able to change its status. This is useful for reporting the general status of the computer. The LED can be green, yellow, or off. It can also blink or maintain a steady color (Table 1).
