I have a Mb LA-A993P REV 1.0 computer, I am guiding myself with these two shared boards. ;
there are some ICs that are not the same, in this case those of the PU1501 (JD4TB) and PUH1 (NF4SA) images.
n, please identify.
330mA of consumption after 8 seconds turns off. +3VALW AND +5VALW present, EC_RSMRST# , LID_SW# , EC_ON# , ACIN# present.
SUSP# NOT PRESENT, which would be this the problem does not turn on sub-sources Any leakage?
I also notice that in the PLH2 coil that belongs to +1.05VS according to the drawings I am not sure,
It has an impedance of 4.1 ohm and when I press the power button it has a resistivity
somewhat low with +V5AlW, i.e. I measure between the points PJ303 and PLH2 a resistance of 20ohm,
After a while that measurement goes away. Could PUH1 be on the run? BE AWARE I notice a bit of temp in the CPU... Pch, to the trash?
