    ASUS N43SL CPU CORE 0v

    Hello everybody...
    I need your help..
    Today i have a asus n43sl blank screen, all led indicator on except the "charging led"

    Found that CPU Core was 0v when processor inserted, but going 1,1v when processor removed. The PWM IC is "ISL95831".
    and then cannot "on" when using battery ("on" here means the indicator lights up but the display is blank)

    I had :
    1. changed the pwm IC ISL95831
    2. changed the processor and test it into another motherboard
    3. changed hub hm65
    4. changed the KBC IC ITE IT8572E
    5. reflashed the BIOS

    but the result still the same. can anybody help me?

    the schematic are same as here I was upload it...

              Don't rull out that the cpu socket may play hard ball on this one.

              You know bga socket cpu.
              Just cook it! It's already broken.

                  Hey dj thanks for your reply

                  Do you mean the cpu socket faulty??
                  But why it cannot charge the battery and on with battery?
                  Is it another charging problem??

                              reflow the GPU and see what it does.
