Slowly slide your finger along the upper edge of iPad 2, and you will find a small black oval button in the upper right corner of it. It has a long name: On/Off, Sleep/Wake.

The following is the function of this button:

1. Turn iPad2 on and off.

Press and hold the button for a few seconds to completely shut down, that is, cut off the power. If you plan not to use it for a long time, turning it off completely is the best way to protect the power life of iPad2. When you close it completely, the following interface will be displayed on the iPad2 screen, your request has been confirmed. If you confirm to close it, just drag the red arrow slider from left to right to the end. To turn on iPad 2, just press and hold the switch button for 1-2 seconds. You can start working again after one minute or after the startup animation.

2. Wake up iPad2 from sleep mode.

Tap the button iPad2 to turn off the screen and enter sleep mode. Sleep mode can save power. You can wake it up from sleep by pressing the power switch button as well. If you leave iPad 2 aside for more than one minute or after the screen saver time you set, it will automatically enter a power-saving sleep state. We will introduce the screen saver time setting later.

Note

When you turn on the iPad 2 or wake it up from sleep, the screen of the iPad 2 will be displayed on the unlock page. You can drag it with your finger. The slider follows the unlock arrow prompts for touch screen unlocking. This is to prevent you from accidentally turning on the phone and causing automatic programs to run when you put it in your backpack or other places.
