Re: Lenovo Ideapad 320 Stuck at 330mA
hi.
1) remove all power.
2) Meter in resistance mode.
Measure and post the:
a) resistance between source (1-2-3) & drain (5) of PQ1001.
b) resistance between source (1-2-3) & gate (4) of PQ1001.
c) resistance between drain (5) & gate (4) of PQ1001.
d) resistance between source (1-2-3) & drain (5) of PQ1002.
e) resistance between source (1-2-3) & gate (4) of PQ1002.
f) resistance between drain (5) & gate (4) of PQ1002.

UPDATE!
I did once more check up before ordering the components. I found PL1003 has a momentarily output of around 0.680v some times while observing with DSO. So I did checking all the resistors around the PU1402. All were correct. Then just by an intuition flashed bios from https://www.badcaps.net/forum/showthread.php?t=72785 this thread, and all went right. Now it does have display.
