Detailed explanation-1: -Every computer today uses a power button for turning on and off a computer. However, many desktop computer power supplies also have a power switch, as shown in the picture. This power switch turns on and off the power supply, and if set to the off position, the power button for the computer does not work.

Detailed explanation-2: -(1 or | means on.) IEC 60417-5008, the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. (0 or ◯ means off.) IEC 60417-5009, the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state.

Detailed explanation-3: -On a laptop, the power button is often found above the keyboard, on the left or right side. It may also be on the far-left or far-right on the top row of keys on the keyboard. If you cannot find the power button, check the left or right edge of the laptop instead.
