So I put the fuse back, connected it to the PSU and nothing... Q7630 shorted again... Removed Q7630 and there is no short to ground on L7630. that is a good thing isn´t it?

resoldered Q7630 and getting 4 kohms from L7630 to PIN 2 F7140, hopefully that is good and I can go ahead and put in the fuse?

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...

Changed Q7630, and still measuring .2ohms, checked L7630 to ground on ohm scale I get 230 ohms in diode mode red probe to ground I get .165 is that a short?

resistance between L7630 and pin 2 of F7140 = 0.2 ohms

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...

U7100 Voltages: 1- 0v 2- 16.30v 3- 4.3v 6- 0v 9- .03v 12- 3.4v 13- 3.4v 14- 3.4v 15- 0.08 17- 3.34v 19- 5v 20- 5v 27- 16.1v resistance between 17/18 - 3.6 ohm 27/28 - 20.3 ohm

I´ve checked all traces, all are good, resoldered q7130, now I´m getting 3,6v at pin 1 of f7140 without the fuse...

no it doesn´t

Changed Q7130 and C7125, traces are good, still getting 15.6v

I have this board, no corrosion found, had a short on pp3v42, that is fixed now, but now ppbus_g3h is at 15.6v already changed Q7130 and U7100 no change...

On battery it doesn´t turn on.... if I disconnect the battery it boots and works fine. If its on and I connect the battery It instantly turns off...

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?

Hola, tengo el mismo problema, sin la batería la computadora enciende y funciona a la perfección; cuando conecto la batería solo me muestra el ICONO como si estuviera descargada. Que puedo revisar en primer lugar?

Hi, this computer was brought in with some corrosion on R6131 and R6133, cleaned the corrosion and tried to start it but still was trying to load, making the chime and turning off... the last thing that happened is that I connected the MagSafe charger and it had a spark on the charging port, now...

Hi I have this board, which tries to load the system, but shows horizontal lines while loading, and then the lines disappear and I get stuck on a white screen... help please!

I have this customer that is asking me to upgrade the ram on his A1398 Macbook, I have a motherboard of the same model (820-3332) with 16 GB, can I change them to his actual mother board? Can this be done? Do I have to remember the position of every chip or is it the same if I just reball the...

I tried the BIOS, it didn´t worked... I refuse to think its a dead cpu, it was one the night before and working just fine... there must be something we´re missing....

And if that doesn´t work? What should I do?? Any sugestion?

Any history available? Left it on and the next morning won´t turn on... Check PLT_RESET_L = 3.3v SPI Bus Series Termination resistors = all with the correct values... Where can I find the BIOS? Can you send me a Link for that? Thank you!
