Turning a Microsoft Surface Unit On and Off

Always make sure that a Microsoft Surface unit is connected to a reliable power source and that the AC/Main rocker switch is turned on. After you set up the unit, you should not have to change the power source or turn off the AC/Main switch again. Turning off the AC/Main switch is equivalent to unplugging the cord from the wall. You should rarely, if ever, have to use the AC/Main switch.

The On/Standby power button is located on the opposite end of the unit from where the AC/Main rocker switch is. It is on the bottom-left corner beneath the I/O connections. To turn on a Microsoft Surface unit, just press the button and then release it.

The On/Standby power button is clearly visible on a Microsoft Surface developer unit.

On a Microsoft Surface commercial unit, you need to feel under the left-corner of the frame to find the button.

Turning Off a Microsoft Surface Unit

To turn off a Surface unit, press-and-release the On/Standby power button.

noteNote
If you are using a developer unit, or if you have switched a commercial unit to administrator mode and attached a keyboard and mouse, you can turn the unit off by closing the Windows Vista operating system by using the regular Shut Down option.

noteNote
If you quickly press and release the On/Standby power button and nothing happens (such as might occur during a system failure), press and hold the On/Standby power button for 5 seconds to turn off the unit. The system cold boots on the next power-up cycle.

noteNote
If you need to turn the unit off and then back on, wait for 30 seconds after you turn off the unit before you press the On/Standby button to turn it on.
