    HP 450 G3 Strange behavior

    HI,
    Got the above laptop. As soon as the power is plugged in all lights turn on, the charging light flashes 9 times orange then 4 times orange/white, the fan spins full speed and then after few seconds restarts and same cycle repeats...... any lead..... I've noticed the I/O chip (nuvoton NPCE586HA0MX) got warm.

    Maybe a faulty SIO, try replacing it.

      I have 2 840 G3's, one with touch and and one without touch. Can I replace SIO's? just for checking...

        NPCE586HA0MX is not programmable. As long as the SIO has the same reference, you can use it as replacement.
