fun. ok getting on this now. it is the last one of this batch.. hopefully i get it working. i contacted the guy who previusly atempted to fix it. he said the only thing he tried to do was injecting around 5 v into L7520 but i doubt this caused any damage
the problem is that the person posting here is retarded: bad keyboard.
forgot these do not turn on automtically. (also bad lcd 5 return resistor R9721 ) can close. sorry for being an idiot
got a 820-2879 that got previusly worked on
anyway, i do not fully understand how u7200 operates here, but it is not opening the 5v mosfets q7260 and q7261 to create 5v_s3_ll
all 3v are present
pp5vs5_ldo is present
pp5vs3 is missing of course, it does not seem shorted to gnd
pin 2 5 6 do the following at on button press/ magasafe in
