    Asus X751SA Power In Disabled

    Hi!

    Two laptop stopped with a same problem at a same day. No power, dead. I have bin investigated, that input dc flow stopped at the first mosfet. I can force the power to flow in, an the laptop works well, except no battery charge. BQ735 changed. Battery changed, still the same. Power in disabled. Mosfets not sorted.

    If i plug in DC, a small capacitor enables power to flow in. After the cap is charged, (and everything is ok) the system enables power in. For a few milliseconds, battery charging voltage is rising. Then stop all, system power disabled.

    Any idea? Schematic have One?

    Thx
