    Like the title says I bought a used huawei mate 9 from craigslist. The seller stated that he couldn't get it turned on so it was sold as is. I do know he let it sit uncharged for a few months and from previous experience that means the battery couldn't charge without a "jumpstart". I had someone test it out at a store called UbreakIfix and the DC charger didn't start up the charging process. The gentleman said that the power management IC chip was probably bad. Does anyone know if it could be the IC chip or if the charging port is bad (the cable isnt loose or anything) and what would be the symptoms for either case. Thanks in advance.

    No one can tell without actually opening the thing up and testing the hardware. The symptoms would be the same either way. It won't charge.

    And if the battery had dropped below the critical point, an external charger with precharge would charge it. (You'd probably have to use a couple of clip leads, since the battery plugs in.)
