    Hi folks, I am trying to ID the correct part to fix a laptop power supply. The component says:
    BA 1718
    (Looks like a smaller version of the IRF7403)

    I thought at first an IRF7403 was the xref. But this is not SOIC-8 rather is a leadless SMD. The only ones I found were P Channel MOSFET (on Mouser). What does BA and 1718 stand for on that chip? I am tempted to solder a bigger FDS6690A I have on hand but I'd rather source the correct part. Any feedback on this is appreciated! :)
