9/22    Anyone notice an annoying "ringing" sound with their Palm
        Tungsten E over time?  Similar to most LCD devices with the
        backlight on but louder, to the point of "piercing".
        \_ Sounds like a bad internal cap or transistor, probably in
           what is the equivalent of the voltage inverter on the LCD.
           Probably will fail over time. The change in sound means the
           component has changed over time, always a bad sign in
           electronics.
