    Need help reading Schematic.

    Hi there

    Was wondering if anyone could point me in the right direction, Schematic "LA-5891p"

    Working on dead laptop or attempting to bring back to life.

    On reading the schematic everything makes sense until I reach this page 47, PU17 ISL6251, please see attachments.

    Getting stuck on pins

    1 VDD is this pin going to pin 15
    2 ACSET where does the X go or mean
    23 ACPRN where does the X go or mean

    Many thanks in advance, thank you.

    It seems those pins are not used. The usual AC function is done by the Vin Dectector on page 44.
