Hello my friends
GOT THIS MOTHERBOARD NOT POWER ON : LA-D711P. ans it's AMD
No schematics/BRD available , when power button trigger only 0.009 amp consumption.
PQ4 and PQ5 are OK :
PQ4 = D19v , G= 24.5v and S=19v
Pq5 = S 19v ; G=24.5 and D= 19v
No short to ground at any coil, and 0.488v at senser resistor with diode mode.
Try to get some measurements when button trigger :
PL7/Pl8 = 3/5 valws present
PL 602 = 0.948v
Plm2 = ram voltage=0V... PUM1 = RT8207 = no s5/s3
U44= KB9022 =
+3VALW_EC = present
pin 27 =EC_CLR_CMOS = 1.5v
pin 113 = Lid_sw = 3.3v
pin 122 = Pbtn_out = 3.3v
pin 100 = rsmrst = 1.5 v
no slp 3/4 , try another bios /ec bios and still the same
What to check else !!
