Ok it´s good to know :)

Im writing from a mac with that board right now, and it uses a 60W charger.

You are welcome

I didn't know about the 1.3V. I have this value (1,3V) on c9560 I changed it but the same problem persist. I have a similar problem with the same board, could you please measure and post values of : r9589= r9585= r9571= ? Thanks

Schematics, if you type Vp0R you will see it. Notice... that is not "O" is 0 (zero) IF not try typing PBUS Voltage Sense Enable & Filter Then check in board view Visual inspection on resistors, if they look like C&B, replace them

I think he means to change it for a normal cap 330 uf polyfilm Did you change it already? Does the GPU start boiling when you play games?Any artifacts?

No Title Ok, What I see is that when the mac is cold, I have no problem it boots normally,chime, everything...but when it gets hot it gets stucked So probably something could be sending more power than what it needs, could be something related with GPU VCore Regulator? Could be any buck...

An apple modification? Well that area it was a little bit bad soldered like somebody was playing, somebody who does not have the correct tools for that. I know they are trash but what I think is that the pch is receiving more voltage than needed, don't tell me again they are trash I know that...

Could be because of that that the cpu gets hot?

Ok I replaced it from a donor board 820 3115. I put the capacitor on pin 1 and because it is bigger then I scratched a little bit on the same ground section because pin 2 is going to ground I soldered but...I have the same problem yet Could be the capacitor bad? or maybe another thing? Update...

Has to be tantalum too?Or could be this one? http://uk.rs-online.com/web/p/aluminium-capacitors/7269893/

Hi, I have an issue with an 820 2850 board I7 green light and orange, chime, apple logo appears or if I press alt it respond well, but after a minute the cpu is getting hot, then it gets stuck showing kind of apple logo artifacts on screen. Where can I start?

When I read this I have no idea what you´re talking about,and I think like me there are few of us. A video about this would be awesome, or any post related to explaining it in several steps.

Ok, at the moment I only need the hinge everything is working good at the moment. Thank you

Any help is welcome

Hi, I have this problem, I saw there was an apple program but it ends on march, this year. Anybody knows a cheap way to solve it? If not, do I have to change only this piece? (pic 1) or the whole piece? (pic 2)

I would love to see a video about that too

Great turbo !! but when was that? long time ago, recently? do you give a limited warranty to the customers?

Hi, Im still waiting for the preballed smc that I bought, but I´ve been reflowing the smc because this board was with liquid damage around the smc. but not directly, now what I have is a green light for 12 seconds then turns off then 12 seconds later goes on...and keep doing it. Does the smc do...
