yes, native 3valw is ok... -
hello friend,sorry to hear that
as i commented. s5_on(pr185) is not present (the resistor) in pu12, only pr184. i simulated with a pr185 bridge. and the result is that it has a consumption of 50ma. and it does not respond.
the s5_on signal comes from pin100(ec) and not 128.
I have measured resistors:
pu11
pin1 24k
pu12
pin1 85k
to make sure it is not the divider I measured on pin128 (ec) same result, 0.11v....Leave a comment:

hp 17-k dont start , problem with 5valw (no 5vs5_on) day31amb6c0 rev c
Hi guys, I need a big help.
i don't have 5valw, (pu12)
the signal (pin 1) from pu12 has 0,11v.
I go back and it comes straight from the EC (pin128) same thing, no sulfate or anything.
then looking at the diagram I see that pr185 is not present, but if you have 3.3v so I make the bridge, now the mother is with a consumption of 50ma put the source. but there is no case nor responds the power button.
With this if I have 5valw.
I leave measurements I made
u3 bq738h
1 19.5v
2 19.5v
4 25.4v
5 3v
6 2.71v
11 2.9v (without battery)... -

lenovo legion 5 15-lmh05 nm-c911 charger problems
Hi guys, well the summary is this:
the equipment arrived because it did not turn on (it had been the original 230w source the problem) then I feed with my regulated source and without wanting to invert the poles. the equipment turned on and turned off.
This damaged the charger and its mosfets both high and low switching.
It also damaged the input mosfet (pq102).
by chance i had another lenovo legion just like this one and i removed the components and tried to turn it on and it turned on but ....... it burned again the high and low mosfets and switch (pq104, pq105, pq103).... -
thx so much friend. i type laterLeave a comment:

asrock fm1 a55m-vs no 1.2v (cpu voltage)
Good guys! I need some help
I recently bought a used processor, I don't know if it works, but the measurements are at least ok. what do you think?
normal diode measurements,
-
processor measurements: vcore 8ohms igp 5ohms.
-
L1785 :
with cpu 55 ohms
without cpu 1.6k
voltage with cpu 0.30V
Replaced apw7120 - same result.
Pin7 ocset to ground at power up with cpu.
Mosfets without problems.

Obviously vcore is missing, not to mention vram.
Basically no 1.2v
well, summarizing quite q36 (it was sending...Last edited by SMDFlea; 12-02-2023, 07:45 AM. -
Re: ps4 supply no12v no 5vsb adp-160fr
Additional Information
ic43
pin1 0,38v oscilates to 0,3v etc
pin2 0,2v
pin3 4.3v
pin4 0v
changed ic43 and nothing
r170 4.8v & 4.71v (ic151)Last edited by totto210; 05-05-2023, 11:49 AM.Leave a comment:

Re: ps4 supply no12v no 5vsb adp-160fr
lol man , and thanks, the problem was the cable
Well, problem one solved, now comes the second, which is the one I mainly had:
I only have 4.8v in 5vsb, should I have in acin_det? Is it generated by ic151 itself?
I make the short between pin 2 and 4 and nothing....Leave a comment:

Re: ps4 supply no12v no 5vsb adp-160fr
hi capleaker,
I already checked everything and I don't see anything strange, could the pfc integrated (ic41) be pulling this down? or the d11? What could I lift and see if I have voltage? If I get d11 could it explode? :S...Leave a comment:

ps4 supply no12v no 5vsb adp-160fr
hi guys, I have a problem, the source recently had 4.8vsb but no acin_det
CN121
1_ acin_det 0v
2_ acdc_stby 0,01v
3_gnd
4_5vsb 4.8v
That was at first, I jumpered 2 and 4 and nothing happened.
I tried to jumper 1 and 2 also, then I realized that I didn't have 4.8v anymore.
1_ acin_det 0v
2_ acdc_stby 0,01v
3_gnd
4_5vsb 1v
a crazy thing
on the main capacitors (c1 and c2) the big ones, I have 1v!
and if I leave the gnd tester tip alone it measures an oscillating voltage between 0.03v and 0.05v !
