Have a 440 G8 fitted with a DAX8QAMB8D0 REV D motherboard. One IC is cracked down the middle, and I suspect this is probably the system agent rail for the CPU. It's dead short, but just wanted to know what IC this is before I take it off. Highly likely CPU is shorted but anyway.

I think the markings (as best as I can make them) are

MPM3
2941
B381

I wiped it with IPA but the first two numbers of the 2nd row disappeared.

Edit: Took the IC off, CPU is shorted. I guess it was driven too hard, failed then 19V straight into the CPU. No other damage to the board.

It`s a Monolithic Power IC https://www.badcaps.net/forum/troubl...20#post1482820

Possibly MP2941GL-Z

Thanks Flea, I think you are on the money. There appears to be an A and B variant from SUHMS for this. No publicly available datasheet for it unfortunately. Did a search in FlexBV and found it in the Lenovo 203013-1 schematic amongst others. Appears to be for the VCCIN_AUX rail in that one.

CPU was shorted anyway.
