Hi on this board I have quarter fan spin, checked already
R7021/22 - right values at 10 ohm
R7051 - 2.5 ohms
r7052 - 0.2 ohms
PPBUS_G3H is 12.63v but goes low to 12.0v and when it goes up again, the fan tries to start... any ideas?
is there a way of protecting the cpu/pch when testing with the PSU? I´ve had now 2 of the same year and model which ended being PCH. It´s frustrating, because it was off, but I don´t know if maybe something I did kill it... Thanks for your comments...
removed Q7630 and checked from L7630 to PIN 2 from F7140 im getting 3 Kohms and going up. Thanks for your patience, I know this is a delicate line and I don´t want to screw it up if it is not screwed yet...
just measured diode mode on pin 1 and 2 of f7140 (red probe ground, black on pins)
PIN 1- .138
PIN 2- .175
Checked big coils and there is one that has the same value that PIN 2 has: L7630, with red probe on ground .175, with black probe on ground .199
I don´t know what else to do to make...
Hi, I have this board and when the battery is disconnected it works fine, when you connect the battery and try to turn it on you only get the "Discharged Battery" icon on screen. It doesn´t boot or do anything further... I am thinking SMC problem there?
