My Evo Will Not Turn On

Problems turning on the HTC Evo smartphone for the Sprint network can stem from several sources -- operator error when attempting to turn on the phone, improper charging of the battery, incorrect battery installation and software errors can all prevent the phone from turning on. By following some troubleshooting steps, you can try to fix the Evo yourself instead of having it serviced.

  1. Proper Powering On Procedure

    • The "Power" button on most smartphones and cellphones does not turn the phone on or off with a single press and release. The HTC Evo is no different. Pressing and immediately releasing the Evo's "Power" button, which is located on the top of the phone, does not turn on the phone. You have to press and hold the "Power" button until the screen turns on, which takes two seconds. Release the button once the screen turns on.

    Charging the Battery

    • The HTC Evo runs on a rechargeable battery installed in the back of the phone. When the battery is depleted, the phone will not work. By properly recharging the battery, you can turn on your phone and continue to use it. To charge the battery, plug the mini-USB end of the AC adapter into the USB port on the bottom of the phone. Plug the other end of the AC adapter into an electrical outlet, or the opposite end of the USB cable into a USB port on your computer. The indicator light above the screen glows amber when the battery is charging. Wait until the light turns green before unplugging the phone. The Evo's battery is not charging if the indicator light does not turn on, which could indicate a problem with the electrical outlet or USB port. You may also need to purchase a new AC adapter or USB cord.

    Battery Installation

    • Incorrect battery installation will prevent the Evo from turning on. To properly install the battery, remove the back cover by sticking your fingernail in the slot between the phone and the battery cover and lifting up. Remove the battery from the compartment and check for the battery's contacts. The battery's contacts need to touch the phone's contacts to power the phone. Slide the battery into the compartment so that the battery's contacts come into contact with the phone's contacts at the bottom of the compartment. Press down on the battery to ensure it is fully inserted in the phone. Place the cover over the back of the phone and press down until you hear it click into place.

    Factory Reset

    • A software error may be preventing you HTC Evo from working properly. By performing a factory reset, you can clear any errors and return the phone to the factory defaults -- but this will delete all of the data, files and settings on your phone, so you should attempt a factory reset only if none of the other methods return functionality to your phone. To perform a factory reset, press and hold the down "Volume" button, which is located on the right side of the phone, and the "Power" button simultaneously until the screen turns on. Press the "Down volume" button until "Clear Storage" is selected, then press the "Power" button. The phone turns off during the reset and then turns on when the reset is complete.
