Need help to ID JCEMH2U

[nicolae788]

Hello,

I am currently working on a ASUS laptop M/B model UX51VZ and i need help to ID the part in the pictures. On it it writes only JCEMH2U.

The history is as follows. The client disassembled the machine without disconnecting the battery pack and when tried to connect the LVDS connector back and of course bunt smell. I found a place, on the back of the board, with a bunt ferite bead as i believe, but the IC it's the main problem, it gets too hot with just pluging the charger connector. No leds light, no start, it's just dead.

I attached some photos of the M/B model number and the IC in question.Also a schematic for this board would be very nice to have, i am still searching for one. Thank you !

I finally found out that the IC in question it's a RICHTEK product, found also in the UX31 Asus board, but i can't be sure if it's the same on UX51VZ board...Anyway, if someone can share a schematic for this board it would help a lot. At least the power section. I couldn;t find anything searching on the net.
