    NP350 SUSP# signal meaning?

    Hi guys, i have Samsung NP350 which had a cap shorted to GND preventing it from working. After replacing it i get standard +5V, +3.3V rails, there is +5V on FAN controller, Bios has +3.3, chipset chip gets warm, front LED's work, power LED turns on when pwrbtn is pressed, LVDS connector has 5V and 19V(LCD_INV), but fan doesn't spin and there is no image on lcd screen.

    KB9012QF (ENE) gets:

    on/off button signal (3.3V)
    reset stays high (3.3V) all the time
    pbtn_out gets high (3.3V) after on/off_btn is pressed
    sys_on gets high (3.3V) when on/off_btn is pressed
    PM_SLP_S3# gets high (3.3V)
    PM_SLP_S5# gets high (3.3V)
    SUSPEND# gets high (3.3V)

    Can anyone tell what those SUSPEND#, PM_SLP_S3#, PM_SLP_S5# are and what are they meant to do?

    Is it normal to have SUSPEND# on when system starts?

    Note: Laptop sometimes turns on by itself, without pushing on/off button... hm...
