Hello,

I know it's not directly related to HDD but if somone can help me identify this burnt IC on my motherboard. I've posted on other forum but no answer.

I've search here http://markingcodes.com/search/c/ld but the marking is odd, I can't find anything. I beleive it's a Mosfet QFN 20. ID burned after a stor/ligntening. Now PC start for one seconds and stop.

Thanks
Sam

Probably "1275C", in which case a TPS51275C.
