HP Probook 470 G2 board schematics

Hi I got this burned smd transistor



Can this smd be found on any laptop board ? I got some 3 broken boards, they got some similar smd's on them, does it have any value or they are all same ?

No, not the same. One is with 2N7002 part number and other is with ME2301.

Often you can replace with many vendors who will have 2n7002 in this sot-23 package. Likewise the damaged part at Q30 is '2301' series transistor in the same package type.

Thanks everyone for help. CPU have short so I gave up. As I see on ebay all have similar problem as mine. Guess that's some serial problem on that boards or something.
