I just found another MBA charger, a Mag 2 albeit had come with another very dead MBA (with tea in it). However , that charger also does not give me any voltage at J7000. Since both my Mag 2 chargers are not giving me any voltage at P1 and P2 of J7000, I am using the Mag1, which came with the...

This board had some sticky food stuff around C7796, I resoldered the cap after cleaning up the area. However, the problem, no green light on mag and no boot remains. Turns out the mag adapter is dead as well, so I am using a MBP mag adapter and want to ask, to make sure that this is not going to...

Thank you 2informaticos. This will be the first time I fire up my new DC power supply, and I am a bit nervous since there is so much I do not know yet. If I am going to inject 5V on 5V_S5 would you tell me where would be a safe point to to so? I just want to make sure I do not make it worst...

I checked resistance to ground for the 5V-S5 at the former R5805 contact points P2= 0.4 ohm, at P1= 5.3ohm It looks clean where I removed the resistor I see no damage which might cause a short. I can send a picture of area if that helps. I measured SMC_PM_G2_EN at U7941, and there it voltage is...

As I mentioned in post 29: After I had removed R5805, it resulted in voltage first increasing and then decreasing over a minute or so to 0V. (measured at P2 of the removed R5805, as well as on P1 of C5800 /L5800 respectively). At first reading it was 2.7V, a minute later it had gone up to 3.8V...

I measured P17 on U7200 , it shows 0V. There also is no short to ground , it shows OL in Diode Mode. The next task you gave me I is very confusing to my noob brain: Neither L5800 nor C5800 are present on my board!!! There are the pads where they belong, according to my boardview, but they look...

Yay, I am dancing a rig over here!!! Thank you so much for helping me discover ASD and the walking me through it. The fans are happy now, activity monitor shows no kernels in panic. I have another 820-2850-A at hand ( I had bought a bunch of these 2009/10 machines in various states to serve as...

Thank you for your patience, this is all very exciting new territory for me. First I had selected 'On Error: Stop' and got the result called Error 1 below. Then I changed it to 'On Error: Continue' and got the following results, I did not even omitted the timestamp. Error count 3 -Check to...

Shall I put R5805 back in to see if it I at least get some voltage back these C5800 and L5800?

I am sorry 2informaticos, I did not fully got it, that you wanted me to take a photo of my test results. If really needed, for you to help me with this, I will run it again of course. I am a bit concerned because my fans were running at 6000 rpm for over 2 hours during the test. I tried to...

I did replace the cap with another from a donor board, same values of course. No hot air was used. Upon reinstall of the cap I measures at C9560 and had the proper voltage there, 1.55V . It booted with the fans on full tilt again. I tried then another known good HDD with OSX Snow Leopard. The...

OK, thank you on the cap info. I will replace them with caps of same value from a scrap board as you suggested. EFI ASD Test came in with just the 2 errors as mentioned above. In the dialog box under Status it says TEST PASSED. In the big field on the top right it said Failed. At the bottom it...

OK, finally got back to this puzzle: Running ASD EFI 3S138 and it came up with "Error-SMC IO failed" , and also " Error: No SMART attributes to check" I am curious about the cap: You are implying that using hot air might have been harmful to my cap. Is this the case for all caps? I only had...

Just noticed in Activity monitor that kernel-task is taking 290% 117 Threads ...whatever that means. I have some more of the capacitors, so if hot air was bad, I can and will take it off and replace with a new one, not using hot air. Fans are still noisy

I did use hot air, as shown in the video. And I did place the cap right side up, NOT as shown in the video. Since I posted this, I just installed and just slowed down the fans with Mac fan control. In Mac Fan Control is showed the setting at 6000rpm, max, when I first opened it. I selected...

2010 15" MBP boots but fans running on high after doing C9560 kernel panic repair I just did the replacement and it did boot up OK into OS, buthave the fans going full tilt. I tried the usual SMC reset and RRAM to no avail. Can you please give me a pointer?

I removed R5805, which resulted in fluctuating voltage measured at P2 of the removed R5805, as well as on P1 of C5800 /L5800 respectively. At first reading it was 2.7V, a minute later it had gone up to 3.8V only to go down again a minute later to 2V and ending up at 0V. D5802 is now also at 0V...

Before I venture into the BIOS reprogramming, which is still quite scary/vague for me at this point, I decided to have a look under the logic board to see what I might find, and to check the power rails: So far I found amongst the regular chips: 1 Potato chips in a bed of dust, ​​​​​​PPBUS_G3H...

Thank you for giving me something intelligible to proceed with, 2informaticos.

Still keep googling for a good video in English to do these jobs on a MBP: Make a bios backup, and how to properly use the the re-programming tools I now have. There is not much out there...at least in language I can understand.Also wonder if I still need to unsolder the chip, given that I have...
