my htc phone dosent want to come on anymore. i put it on the charger all night and it still dont come on


Your battery may be drained or is not seated correctly. Remove the battery and inspect the contacts. Remove any debris/residue found on the device or battery contacts with a soft, dry cloth. Attempt to charge the device. If the battery is dead, the device will need to charge for a few minutes and then should power on once this happens. Attempt to power the device on by pressing the Power Button for 3 seconds. Try another battery. If the device still will not power on, contact your wireless carrier for further assistance.
