Hi all. Greets from the UK. I think I already know the answer to this question, just need clarification. Take out of the equation the customer will whine like a rusty bearing when I quote for the repair, will try to bid me down, even though my component level skills are much better now i do not...

Hi, recently I had the same type of issue and the guys here recommended the trackpad. I tried witha replacment trackpad and cable to no avail. customer took the laptop to the apple store and they deduced it was the trackpad. however, when the customer got the laptop back theyn had charged for an...

2informaticos see, this is why you get the big bucks for the big jobs.... you hit the nail on the head with the adapter. customer gave me a 60w and swears blind this is what they have been using, used a 85w adapter and powers on. get the chime and an apple logo on the screen but no illumination...

2informaticos got these readings:- PP5V_S5 = 5.043V L7260 = 3.323V SMC_PM_G2_EN = 3.476V (STEADY) JohnB8812 I had a feeling this may be the case but was not sure. After a bit of searching this would seem to be the consensus as to the most common cause of failure. In both of your opinions is...

Hi all, greetings from the UK... again. Now i am a little lost with this... nothing unusual. MBP A1297 820-2914-A. Red bull definatly did not give it wiings. Keyboard naffed. Green LED on magsafe. No power. Motherboard surprisingly clean and dry. no corrosion visible across the board even under...

Hi, got to love great british delivery companies... 3 days for a next day delivery...LOL. Anyhoo, new battery in and all working fine. Thanks for the info 2informaticos I checked the lines when I had the board out and even though it was in place, nothing was screwed down so it wouldn't have been...

2informaticos Sorry I misunderstood. I have mentioned before I am new to the component level repair. I assumed that you meant check for short when you mentioned ground. The battery should be here later today, so going to connect it and see what happens. If I hit any issues, I will remove the...

JohnB8812 Thank you sir. Just goes to show chicken does not cure all...LOL Battery ordered. Thank you both for your help again. much appreciated.

OK, so 2informaticos no short to ground tested on pins 5/6 of the battery connector. Positive probe on the earth, negative on the pins. JohnB8812 I have 12.57v on PPBUS_G3H so as close as. My deduction with both of your help.... battery. Would this also cause the no detection of the charger...

2informaticos I do not have another battery to hand. In respect of PC's, I do use Chinese imports as they are not so unruly with PC equipment, but always buy original for Apple products. Unfortunately, the cost of the battery here is £80-100 and I don't wish to buy one just yet without checking...

Hey Hey!! Back again with another stooooopid question. A1398.... liquid ingress ( chicken soup). No power. Plug in charger. Green to Orange. Stays on orange. Not powering on. Did SMC reset, powers on... boots fully. everything working fine in respect of keyboard, wifi etc. However, battery...

Hi sorry for de;ayed reply. Customer was happy to revert to Yosamite, so I did that. His machine did have 2gb in it and the issue was the same when I installed a WD Velociraptor 250GB. My machine has got a Seagate 7200 RPM 500gb in it. His machine has an original 160GB ( may have been replaced...

Hi all. I hope this question is OK here... if not could the mod's move it to the correct forum.... OK, iMac A1224. Did have Leopard on it. Now been upgraded to El Capitan. This is the customers machine. I also have in the workshop the same A1224 with El Capitan. I thought the issue I had was...

Hi all. Just an update, the customer has requested i replace the logic board as ( in his words) he is not confident that other components will not fail in the future, and seeing as the logic board is not that dear he wants to replace. on top of that he found an i7 board with 8gb RAM so he opted...

right got you.... thanks for the pointer

2informaticos sorry, will avoid this in future... :) Marc

Thank you, I will try that on Monday. Should ppins 18&19 stay at 3.3v? Marc

You are correct, I had so much I wanted to put in the description i forgot that... pins 3&4 do provide 3.301v and the screen is illuminating ( can see the difference as the system starts and if I disconnect the magsafe it goes dark black) but no display ( image or apple logo) and the reason I...

Hi all again, back to pick your brains. Now as I said before, I am new to the world of mac related repairs and there is a really good chance I may have got this wrong but here goes. Customer has brought in an A1466 with a 820-3437-b logic board. As the title suggests the owner droped milkshake...

I totally agree with that you have said. I did use a "NEW" cable that I brought via eBay and a cable from another A1502 that was a known worker. I took the cable from that machine after it was suggested earlier in this thread. And I do know in the great world or electronics that some parts may...
