Re: la-9104p MB 7 Beeps error and no display

caps in ram area will show low rating

@mcplslg123 how much is low? I have around 30 Ohms on the mlcc near RAM area.

VCC_AXG_SENSE is connected to +VCC_GFXCORE_AXG inside the CPU.
VSS_AXG_SENSE is connected to ground inside the CPU.

another LA-9104P MB with out +VCC_GFXCORE_AXG but the interesting part is the Mob power’s up and working fine how is this possible ?

If you check with dmm then voltage will appear for a brief second on +VCC_GFXCORE_AXG. You need a scope to check this. Same on dell vegas turis 15341-1 mb.

Your are absolutely correct the voltage rise up 0.864 & Back to 0V is the SOC need to replace?

What is the problem you are facing?? You said at post#43-its working fine. Confused??

Re: la-9104p MB 7 Beeps error and no display

The one with constant output on +VCC+GFXCORE_AXG is not giving display. Right??

Yep that's correct What is the reason for this

Re: la-9104p MB 7 Beeps error and no display

Dont know the reason but what i've observed on this mb is that there will be no display when
01.You have constant voltage on GFX Coil
02.When there is No voltage for a brief second on GFX coil.

I've noticed the same behaviour on dell 15341-1 MB. Display comes only when there is a voltage on gfx coil for a split second only.

Trying to understand why.
