I don’t know about you, but when I got my new Pre from the Sprint rep I started playing with it right away.  Manuals?  Pshaw!  One of the first things I ran into that surprised me is that the center button didn’t turn on the phone.  I soon found you could turn on the Pre by sliding the keyboard open.  This was the method I used for a while.  Then I began to wonder, “How do I turn this thing off?”  I couldn’t find any way to turn it off!  The power button on the Pre is so well disguised I didn’t even know it was there.  So, with that in mind, I present this guide to turning things off and on:

Turning on the Pre

The following methods will turn on the Pre:

• Press the Power button:
  

  (1) is the power button

• Slide open the keyboard when it’s closed
• If the keyboard is open, press any key
• Insert the USB cable connected to a power source

Pressing the power button turns on the phone in locked mode, the other methods do not.

Turning off all radios

“The cabin door is now closed, please turn off all electronic devices.”  If you need to turn off all the transmitters in the phone quickly, Airplane Mode is for you.  Enabling this mode will turn off all radios, disabling it will turn back on the radios that were on when it was enabled.  After enabling Airplane Mode you can turn individual radios back on using the methods below.  To turn Airplane Mode on or off:

• Tap the connection menu (upper right corner of the screen where the signal strength bars are), then tap Turn on Airplane Mode or Turn off Airplane Mode.
• Press and hold the power button until a menu appears then tap Airplane Mode.

You can tell you’re in Airplane mode because the following icon appears in the upper right where the signal meter usually goes:

Turning on and off WiFi

WiFi decreases battery life on the Pre.  You can disable WiFi when you don’t need it.  Here are a few ways to enable and disable it:

• Tap the connection menu (upper right corner of the screen where the signal strength bars are), tap Wi-Fi,  then tap either Turn on Wi-Fi or Turn off Wi-Fi.
• Use the above mentioned Airplane Mode.
• Launch the Wi-Fi app and click On or Off.

Turning on and off Bluetooth

Bluetooth can be another battery drainer.  Here’s how to enable and disable it:

• Tap the connection menu (upper right corner of the screen where the signal strength bars are), tap Bluetooth, then tap either Turn on Bluetooth or Turn off Bluetooth.
• Use the above mentioned Airplane Mode.
• Launch the Bluetooth app and click On or Off.
