3 Connector identification for Y740-17IRH
I was performing maintenance on my Y740-17IRH laptop for overheating issues, and I'm trying to identify the type of connector used on the left/right speaker and the button battery. If I can buy only the connectors and replace them (a couple crumbled from heat stress), I think I could save almost $100 because the other parts seem to be okay.
Does anyone know if they are JST, and if so, what type? If not, would you know what type?
They appear to have a pitch of 1.5 - 2mm, and are flat on the wide male part with no notches, but the appearance from the top and bottom looks like a Greek column with narrow shoulders at the end, and wider shoulders at the base where the wires attach.
Any help would be appreciated,
Kelly

After looking at mini-micro JST 2-pin connectors on Amazon, I don't think they're the same. My Legion connectors are slimmer in depth, and have a step in the shoulder that is intended to prevent the shaft from pushing all the way through. Also, no ridges and channels lengthwise, just a single small button in front of the ends of the wires, and two little fins at the end to guide the plastic housing.

@kellyhicks awesome lets see what we can find out. This company claims compatibility for the CviLux connectors. Have a peek until we can find the one for your computer. https://www.jkuncn.com/test-a1255-wire-t...
