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,

Hello,
I have a Lenovo MB LC40CM 19863-1 when press button is pushed the keyboard backlight turns on and off twice and the power button light keeps blinking and the fans spins for a few seconds and stops then again spins and stops (Three times) then laptop turns off. no image on screen. sometime when you leave it for few days it will turn on and work but once you restart it won't turn on.
Tried to reball RAM 1,2,3,4
Checked all voltages on big coils all present except 1V_VCCGT is not present I get 0V on this rail. is this voltage should be present once power button... -

Hello fellow Badcappers,
I have a problem with stubborn Surface Pro 7. I narowed it down to disappearing SLP_S4# (gone after around 200 ms).
Everything else works as it should (the whole power on sequence succesfully finishes, all the voltages are present) until this signal goes missing - with it missing the AND gate causes ALL_SYS_PWRGD to go back low and this makes VCCIN drop to 0 V as well. Interestingly the SLP_S4_DRV# signal from SAM is still present for a second, even after SLP_S4 is no longer there. I wonder what could either cause PCH to stop sending the signal or what...
