    Hi all, my m18x doesn’t turn on, I press the power button and you can hear that it’s trying to boot up and then a sound then it shuts down right away.

    Anyone have any idea what I should check first, cpu or mobo? Or is it time to say good bye :(

    And the "how many beeps does the laptop make" is per cycle.

    Example:

    8 beeps:

    BEEP BEEP BEEP BEEP BEEP BEEP BEEP BEEP *1-2 second silence* BEEP BEEP BEEP BEEP BEEP BEEP BEEP BEEP

    Hope that helps

    there are no beeps, it doesn't post, it seem to want to draw power and shuts down right away, as soon as i press the power button, you hear a small whine like something is powering on and then in a second or less, its shut down.

    Recap: press power button, fans turn on for half to 1 second and it shuts down.
