    I already Flashed the bios same issue

    PM_PWROK_SOC- 3.2V
    ME-SUSPWRDNACK- 0V
    AC_IN_OC# 0V
    PM_PWROK 3.2V
    +1.0VSUS0 1.V
    PM_SUSC# 3.1V
    PM_SUSB# 3.1V
    CORE_PWRGD 2.9V
    +3VA_EC 3.3V
    EC_RST# 3.2V
    PLT_RST# 3.2V
    5VSUS_ON 3.3V maybe this is the issue?
    3VSUS_ON 3.3V
    ME_ACPRESENT_SOC 1.5V also this?
    +1.5vs_PWRGD 2.7V also this is not normal?
    ALL_SYSTEM_PWRGD 3.2V
    PM_RSMRST# 3.3V

    Measure all the rails as per sequence on Pg3 of Repair guide. Check Powergood signals one by one. Since board is taking 115mA, most of the rails are likely to be present as this mb posts at about 140-160mA but should go upto 220-240mA during post.

              with ram and without ram equal 110 amps

              the ram is already tested to other unit and perfectly fine
