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,

by ProttHello fellow Badcappers,
I have a problem with stubborn Surface Pro 7. I narowed it down to disappearing SLP_S4# (gone after around 200 ms).

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... -
by lapfixHello everyone.
lap and motherboard : IdeaPad 3-15IGL05 Laptop - Type 81WQ
NM-C961.
Behaviour : connect charger it power on automatically ,reach 0.170 amp than down to 0.74 amp...no display.
with battery connected it reach 980 amp than 870 ...no display
No short ; no corrision no intervention before.
Try 2 differents bios versions same behaviour.
Some measuremets :
PL 1600 = 5valw present
pl 1100 = 3 vlalw present
pl 100 = 0.221 v without battery and when battery connected 7.8 volt
pl 6602 = 1.2 v
pl 6603 = 1.056v... - Loading...
