Hello I'm currently repairing a lenovo ideapad s740 (intel i9 9th gen + gtx 1650) had got most of the issues solved, but in the end one ic is burnt and gets pretty hot, an AJ7, it's a 16leg qfn 2x3mm ic, I tried to find this everywhere, but couldn't make it, there are some AJ but those are different. Now this ic Is close to the first mosfet (it's not connected tho), in that part of the board there's nothing except for the edp connector and a little fpc that leads to some led signals (cpu, lenovo key and that kind of stuff).
I leave a picture of the ic on both sides, maybe someone knows what...
