    Has the machine powered up at all and was the board already used when you bought it? If refurb you probably gotten a potato, either the charger has an issue or something is wrong enough with the board for the psu to turn off which is a bad sign. I am thinking strongly that something is wrong with the board.

    I got two of these machines and have seen a few of them pop up on eBay with dead boards. Dead cpu, ram, and graphics card won't turn off the charger when just being plugged in.

    Are you sure the power adapter is good? Try testing it if you aren't sure, and if you can't do that i'd just replace it unless its new. Cheaper to do that than the whole laptop.

    The light coming on is not a 100% reliable indication of it working. If, as I expect, the PSU has a 19.5V DC output then it should work with most other Dell notebooks and the PSU from another Dell notebook work with the m1730 (at least under light usage). If you can find another Dell notebook then try powering it with the m1730 PSU. However, as others are suggesting, there is a fault with the m1730 so that it's overloading the PSU (which would cause the light to go out) then it would be prudent to not plug the other PSU into the m1730.

    Hi guys just tested the power adapter with a multi meter and it's 19.42v so that's okay
    What else could it be is it the motherboard plug connector
