After there is a power interruption or when I have done a full shutdown, the power button on top of the computer will not turn on the unit. I can unplug it for a few seconds and it will start and run normally.

What is causing this?

[Edited the thread to add model name to the title]

    Please Post a model number

    Does the light turn on ??

    Are you holding it for like 5 seconds.

    The switch may be bad.

    Easy to prove with an ohmmeter.

    The model no. is TC-1760. Yes the power light always comes on and yes I have held the button down for several seconds.
    The problem is intermittent. It works as it should some of the time but not always. There doesn’t seem to be a pattern.

    Maybe a bad switch,

    Bypass with a test switch or buy a new one.

    If it's mounted on a circuit board then check and resolder as needed, the solder connections on it.

    Thank you Larry! I will open it up and see what I can come up with.
    Since the fault appears to happen randomly I had first assumed a firmware glitch but will test the switch and see what I find.

    I reread and see after a power interruption.

    Who knows ?? ANYTHING IS POSSIBLE ?

    How often do you get interruptions ?

    I live rural Missouri. Power interruptions occur during both storms and substation switching. Even the brief ones can reset the clocks and cause computer and router restarts. These occur a couple of times a week on the average but not every one will result in me having to unplug the computer to restart.
    To confirm, when the computer is on, regardless of how I restart it, the power light is always illuminated.
