Re: Lenovo G50-80 Turns on and off within 4-5 seconds
Made a bigger list now. Measured also the signals Mcplslg123 named. I measured everything three times because I got different readings as in my previous reply:
SYS_POWEROK pin 8 0v
SUS_VCCP pin 34 0v
PBTN_OUT# pin 86 3.3 v
PCH_PRW_EN pin 97 3.3v
PCH_PWROK pin 99 0v
LID_SW pin 109 3.3v
PM_SLP_S3# pin 18 0v
PM_SLP_S4# pin 21 0v
PM_SLP_S5# pin 106 0v
PM_SLP_SUS# pin 87 0v
EC_ON pin 111 3.3v
EC_LID OUT pin 2 3v
EC_VR ON pin 125 2.5v
DPWROK
DPWROK_EC pin 35 3.3v
EC_RSMRST pin 93 3.3v
PCH_RSMRST#
PLT_RST pin 22 0v
VCC pin 11 0v
AVCC pin 74 3.3v
SYS_ON pin 107 3.3v
MAINPWON pin79 0v
ON_OFF pin 110 3.3v
The fact that LID_SW is 3.3v bothers me. I guess this is the signal that tell the computer the screen lid is closed. I can imagine that the laptop want fire up in that case. More is the fact that the laptop has had a fall causing one of the hinges has been broken. I have not been able to find a fysical switch or something in the laptop so I don't know how it gives the signal open / closed.
