Setting the I/O Function and When you will be Required to Use the Back On/Off button
Settings in the Maintenance Menu
Under Windows Power Management - I/O Function
You can choose what you want your device to do when you select the ON/OFF key 
on the front of the case to turn your device Off.
The default is Stand By, with Hibernate and Shutdown as alternate choices.
Stand By
This is the default setting. When you use the front ON/OFF button to turn your device Off, you must use the front ON/OFF button (or a switch) to turn your device back on. In this mode your device will come back up more quickly than the other two modes. It also returns you to where you were before it went to sleep.
Important Note! The following settings require you to use the Back ON/OFF button to power on the device.
If you select this option, when you use the front ON/OFF button to turn your device Off, you must use the back ON/OFF button to turn your device back On.
This option completely shuts down your device – the same way the “Shutdown” command does on a computer. In this state your device uses almost no energy. It also means that it will take your device longer to come back up when you turn it back on.
If you select this option, when you use the front ON/OFF button to turn your device Off, you must use the back ON/OFF button to turn your device back On.
This is very similar to Sleep except that your device goes more deeply “asleep”. Therefore it takes a little longer to go into hiberation and to come out of it when you wake it up. Unlike Sleep, however, you must use the back ON/OFF button to turn the device back On.
If you have set your I/O Function to Stand By or Hibernate, this option allows you to completely shutdown your device without changing your ON/OFF button. You must turn the device back on using the back ON/OFF button.
Release the Device from Shipping Mode:
1. Plug the battery charger that came with your device into the battery charger jack in the connector module on the back of your device. Plug the other end of the battery charger cable into a working wall outlet.
2. On the left side of your case, towards the top back, press and hold the BACK ON/OFF button until it glows blue. Then release it. Your device will boot up. This may take a few minutes.
3. Leave the battery charger plugged in until the Charging LED on the front of the case begins to flash very slowly or stops flashing. This may take awhile. A slow flash indicates the batteries are full but the charger is plugged in.
4. From now on, use the FRONT ON/OFF button on the front of the case to turn your device Off and On.
