Helo folks .
Dell inspiron 3542 -13269 1- not power on , it consume only 0.02 ampers and when i press power button reach 0.03.
Pl4501/4502 = 3/5 V always present .
U3601 :
5V_S5 and 3D3V_S5 are present , but no enable signal = PM_SLP_S3#.
When i press power button the ena reach 0.680v than 0v.
5V_S0 and 3D3V_S0 are not shorted.
Flashed bios same ,verify the RTC section find nothing unusual .
Have some doubt about Gate of Q2402/2403 !
I take this measurements maybe someone have an idea .Thank you
D2501 = RTC present
G1901 = 3.15v
RN1901 = 3.3v on 4 pads
Q2402 :
G=3.34 S =0v D= 3.34
IO basic requirements for swich ON =
73 = PSL_IN1# it should be low = 0v
93 = PSL_IN2# = 3.3v than press power button should be 0 than again high
74 = PSL_OUT# = 0V
14 = S5_ENABLE = 3.34v
85 = ECRST# = 3.33
15 = RSMRST#_KBC = 3.31
117 = PM_PWRBTN# = 3.41
112 = AC_PRESENT = 3.41
100 = PCH_PWROK = 0v when press button the v rise upu to 0.700 than return 0
21 = PM_SLP_S4# = 0v when press button the v rise upu to 0.400 than return 0
77 = SUSCLK_KBC = 3.3v
