Try holding both the power and sleep button at the same time for 10 seconds. Should soft reset. If it doesnt reset then maybe a power buttnon issue.

I connect the charger of my htc hero. at first it was charging. after an hour i noticed that it stopped from charging. when i turned on my phone it didn,t open.


Open the back cover , take the battery out . Press and hold the power button without the battery . Put the battery back in . Try to power it on .
If that doesnt work try below steps , ( note : you will loose your data )
Power the device OFF. Press and hold the HOME and Back Arrow buttons. While holding these buttons, press the End Call button once. Release the Home and Back Arrow buttons and press the Trackball to execute the Hard Reset. The device will reboot once the process is complete.
Thumps for my solution if it works .

How to turn off


On most cellular phones you can power off by holding the "end call" button until the screen begins to shut down. If this does not work, search for a button that has the power symbol on it (It should look like a Q) and hold that button. If neither of these methods work, it's best to either contact the company, speak to your cellular plan provider, or refer to the manual provided with the phone. If you need anything else, let me know!

You should try completely shutting off your phone and getting it to start back up again. Many cell phones will have their power buttons the same button as the End Call red button. Hold the button down for a few seconds to shut it off, then hold it again for a few seconds to start it up again.

If you can't get it to turn off, try removing the battery and then replacing it and powering it back on. If this doesn't help it, you may need to replace your phone.

How can turn it on again?


The red phone icon on your phone (end call button) is also your power button. Hold the button down and you should be ready to go. If that doesn't work I would suggest calling your carriers technical support line before trying to fix anything yourself. You could void your warrenty.

Wont turn off


First, take the battery out and put it back in to reset it. Then try again to see if you can manually turn it off.

This resets the phone and is the first step in troubleshooting.

Another thing I would do, is test to see if there is something wrong with the end button itself. With a flip phone, normally the end button is unneeded because you close it to hang up. Try ending a call using that button to see if it is a broken keypad issue.

I would also have the local store update the firmware, which should repair any files that may be corrupted, if that is the case.

Also, if the phone has any water damage (when you open the back of the phone, there will be a red dot instead of a white one), this can cause all sorts of crazy problems.

If none of the above solutions work, the only other way to power your phone off is just to remove the battery. You should be able to put the battery back in without the phone restarting, but if it does, just keep the battery out when you want the phone off.
