Hello, This notebook returned with the same problem! It only keeps on the SMC bypass, gives video and enters the system but very slow. The mouse does not freeze, as a symptom of sensors, but the programs respond extremely slowly. And even turning on Bypass, right after I shoot and put the...

Removed the requested resistors. Also disconnected the J6955 and tested with another DCIN board and got the same symptom. Only the board on the workbench both with all its connected peripherals gets the same symptom.What do you think?Do we have anything else to do before then?

I don’t understand why you put (/) at the end of the component, because that being only 1 resistance R5222 Would it be for me to remove the resistances r5222 and the r5223?

I already put her plate in another case of another Macbook that I know to be working perfectly, so the question of TP is eleminada, the flat also put a good one. I’ll try the other procedures!

In the diagnostic test gave the following error: 4sns/1/C0000008 TPCD-124

One thing I noticed is that the felx of the TP is oxidized, replaces the same, but the symptom persists, the cooler is gradually rotating 0until it is 100% and very slow system! I looked around the TP connector and found no oxidation. Another thing I noticed is that the battery does not...

Procedures performed and continued the problem. Can you tell me how to use Apple Service Diagnostic to get information about which area the problem is occurring?

I had replaced before because I was instructed to do the procedure in another technical forum! And yes, I already did the testing procedure with the charger and it resulted in the same thing!

I replaced his Smc and the problem persists.Only turns on in Bypass mode

Well, I’ve been using an asymmetric font for tests always your right! never gave any problems in relation to other macbooks.

One more for you! Plate is in great condition without any sign of oxidation! I’ve tested another keyboard and nothing, and now I don’t know what else I can do! I know the problem has to do with sensors, but I don’t know what to analyze in this case. I await instructions, thank you!

So... I’m back in that MacBook! And I was surprised when I did the SMC bypass process and the machine actually turned on! You’ve been using it right and everything! And now what? What would be the next step? It only turns on that way, daforma conventional nothing.

Yes, I’ve done both. I’ve changed the cooler and even the sink. It gave an improved, but I do not see change the rotation of the cooler when it passes the 75º is always in the same rotation! The concern is whether it got cold solder on the SMC or something! But the machine keeps running and...

I did Reball and he did the same process about two or three times, then started calling normally. Now turn on every time correctly! Only one detail, the cooler turns little and heats up a lot, reaches 90º and disarmed. I had to download a software to control the fan and it answered...

This Macbook League, gives consumption quickly without video, disarms and light turns orange. One thing that the customer said is that of trying so hard, an hour turns on the goes, but is very slow, really turned up front before we entered the device but on the bench he did not call once...

Do not understand, how to do the SMC bypass process?

Do you think that while I wait for the load, I can do something like, reset the BIOS, or would it be a waste of time?

I don't have an original 60 or 85W charger, it will take a while to arrive if I order 1 for testing. From the tests I did on other macbooks, with the asymmetric font, I didn't have similar problems, I don't think it's the font, but I'll follow your instructions! Is there anything else I can...

One thing I noticed, is that when plugging the charger, the resistance of the side of PM_BATLOW_L goes at 200 Ohms and when I shoot the charger, back to 0 Ohms. I also noticed that there is a Q3000 reference transitor that is connected to this line, maybe it may be causing this problem, i’m not...

I’m using a parallel charger from the client itself, but I tried an original 45W and now I’m using it straight from the asymmetric source and all point to the same result of 0.3V On the other side of the resistance I have the PP3V3_S5 but passes only 0.3V but the resistance is with its normal...
