Recurring problem, blinking green magsafe, does not turn on.
So the powerails are ok. But when I look om =PPBUS_G3H or DCIN or any other rail, I see a strange recurring pulse. See picture attached of PP18V5_DCIN_CONN power rail. it is on 820-4924, but I have had this problem on other boards to 3115,2915 ect . Sometimes it solves it self, other times not...- Sjenja
