[QUOTE="user 997, post: 1141735, member: 997"] It is probably an ISL9241H buck/boost converter from Renesas -> See [URL='https://www.renesas.com/us/en/products/power-power-management/battery-management/multi-cell-battery-charging/isl9241-buck-boost-configurable-battery-charger-smbus-interface-and-usb-power-delivery#overview']ISL9241H datasheet[/URL] You can order parts from Mouser. You would need to figure out which specific ISL9241H part it is. The latter code that you provided could be a manufacturing date or a serial number. Look if they have a part number that matches the one you have in the datasheet. The ICs are around $10 ea and it seems to be a commonly used part. Since I believe that laptop charges over USB-C it is unlikely that Asus would be using a custom chip. I think more of an issue would be to get it correctly soldered, so you would need somebody with a steady hand and good soldering station to be able to get that safely off. You might also need to check some of the capacitors for damage. I still find it disappointing that manufacturers expect you to replace the entire mainboard for a circuit that could easily be placed on a separate daughter board, since this is a quite common failure point.
