The component in the posted pic is an EEPROM - not a mosfet. Hunt for mosfets of same physical size and they should reside near the DCin power connector of each donor board. Then search for their markings using Google to locate their datasheet. Confirm the type is the same. That is N-channel must be replaced with N-channel. P-channel must be replaced with a P-channel mosfet.

I have a liquid damaged LA-J871P board. Liquid was in different spots over the board, but mainly around the BQ chip PUB1 (had to replace the 24781 with a 24780S, few resistors and a jumper). Board passes 19V and charges battery. EC LDO is fine and responds to power button.

Other liquid damage was on and around the PCH UH1. Power sequence stops at PM_SLP_S4 not being issued out of the PCH. RTC clock appears to be working via a scope but the PCH 24Mhz clock is inactive on power on. Does anyone have a working board they could give me some readings off? Not sure if this is liquid under the BGA or the PCH itself is kaput since it did have some minor corrosion on top. Resistance on PL1101 is around 50 ohms at room temp.
