Center button will not work - Palm Treo 500 Centro

please be more descriptive. The make of the tablet, what exactly lead to the issue,

you may try by leaving the tablet charge overnight but ensure that the charger is working before doing that. If the tablet haves center button you can try to press and hold the power button and keep tapping the center button for about 15 times. It might turn on if no center button try holding power and keep tapping power down. When you are up to it, you may even try the combination with power up button as I don't know the model.

Hi,

If only two buttons are not working then it means there is carbon on the particular buttons if your an technician then you can do it easily if not then please visit your nearest Nokia service center (nokia care) or any mobile repair center they will do it.

With the car on, hold the outer two buttons release when display center says channels cleared, this clears stored codes. Then while holding the garage door opener 1 to 3 inches from the homelink buttons, press BOTH the garage door opener button and the desired homelink button, release when the display center says channel trained. Then test the button, it will say transmitting on the display center if it worked.

This has happened to me as well. On two handsets the center buttons do not work! They are too expensive to buy new ones after one year! Don't buy Uniden!!!

ur center button might be damaged due excess pressure applied try taking ur phone to nearest samsung care center they will definitely repair ur center button.

well, i can't even tell you to reset your ipod because the center button is not working, hehe . whatever ....

i guess the only solution is taking it to an assistance center , must be a problem with the energy reaching the button .

Try pressing the menu button and center button together until the Master Reset begins
