    Hi,
    I have problem with this laptop, mobo is completely dead, no lights, fan spin ..
    When power adapter is connected PU401(+3VALWP) overheating. After I lift up PU401 there is no short, but i found another two shorts to gnd - on power rail for cpu - +1.05VS_VTT and on 3VALW_PCH. I mean this is problem in U1-CPU. Can someone help me with this? Thanks.
