    Hello Trevor,

     

    First of all, I assume that you are using a working 45 W power adapter with a 24 V DC output  (low-voltage plug: centre positive, outer ring negative).

     

    The PowerBook 5300 has a standard problem with a loose DC low-voltage connector. If necessary, the connections to the board can be resoldered (details can be found through a web search).

     

    Older computers may have issues with leaking electrolytic capacitors. A careful inspection of the board(s) should not show any signs of leaking/damaged/discoloured components, nor of cracked/bad solder joints.

     

    If a faulty main battery is suspected (can put a heavy load on the circuits), one could check whether the PowerBook starts up with this battery removed.

     

    Try to reset the power manager and to reset the PRAM.
