Hi all,
I have a Lenovo Yoga Slim 7 ProX (model: 14arh7 R7-6800hs without nvidia gpu) with a USB-C charging fault.
USB-C port area gets extremely hot when the charger is connected, and the laptop won't charge. On inspection I found a chip marked GBVUE1X0801 (one of four identical ones on the board) with a visible black/burnt mark on the package, located near the USB-C charging circuit, I dont know if it the culprit or something else is.
Anyone got Schematic and boardview for this motherboard, specifically the USB-C PD/charging section ?
I've checked VBUS-to-ground resistance with a multimeter and confirmed a short on that rail. Trying to do a board-level repair.
Any help finding the schematic/boardview, is very much appreciated.
