- 3/5V always is ok
- 3/5Vs is ok
- 1.35V is ok
- 1.05v is ok
- Cpu core 1.8v at Pl9
- +LCDVDD_CON is 0V---PCH_ENVDD = 0v (U5)
- Pltrst is 3.3v at pin 22
- 1.5 Vsp/Vs is ok
- CPU_DRAMRST# is 0V
Flashing Bios same issue
Some Volt On ite 8586e before/after pushing power button
110 - ON/OFF - 3.3V / 3.2
76 - NOVO# - 3.3V / 3.3
26 - VCC - 3.3V / 3.3
74 - AVCC - 3.3V / 3.3
97 - PCH_PWR_EN - 3.3V / 3.3
93 - EC_RSMRST# (PCH_RSMRST#) - 3.3V /
86 - PBTN_OUT# - 3.3V / 3.3
18 - PM_SLP_S3# - 0V / 3.3
21 - PM_SLP_S4# - 0V / 3.3
107 - SYSON - 0V / 3.3
34 - SUS_VCCP - 03.3V / 3.2
124 - SUSP# - 0V / 3.3
125 - VR_ON (EC_VR_ON) - 2.5V / 2.48
99 - PCH_PWROK - 0V / 3.3
30 - SYS_PWROK - 0V / 3.3
I Use Lenovo IdeaPad 100 series LCFC NM-A681P CG510 rev 0.2 schematic , no BRD available .
