HP 6910p (La-3262p) Ram Voltage 0.9 Laptop Running

[Ariox]

Hi there,
I have a hp6910p with one ram socket (socket b) dead
With a ram at socket A the laptop works perfect

So i have at PU17 ( TPS 51116RGE) pin 5 ( vttref) 1.8 and at the pr127 0.9v
At slot A at and slot B
at c362 and c363 (slot A ) 0.9V
at c90 and c89 (slot B ) Again 0.9v
Both slots have +3vm
So how can the slot A work? ( With 0.9v?) and slot b not?
with 0.9v both slots have to be broken right?
Thnks in advance
P.S
If i short PR127 i still have 0.9v
Thnks

Did you try with other memory. If not memory incompatibility, then probably problem with Nortbridge.

Tried with spare working memory
Nb..reflow reballing?
That i cannot understant is why slot A is working with 0.9v...

Reball it and better replace it, reflow usually makes it worse.

0.9v is normal, is termination voltage.
