Not a steady light on the lite on which after checking has an aftermarket cable but is on the delta, my 858d would kill a smc in my opinion I have to run at max temp to get macbook parts to move anyway. If SMC is the only option I'll have to leave this just think its weird it works on battery...

I think theres some gunk in that area dont know how i measured 2.83v twice but im 0.25v on some blank areas around it so have used my ultrasonic toothbrush and getting a clean 3.41v. same symptons

Theres no off while a charger is connected just fan spin then turns off and repeat. done U6900 1 3.42 2 0v 3 0v 4 2.86v 5 3.4v u6901 1 2.33v 2 2,33v 3 0v 4 3.43v 5 3.43v

Thanks flashed that no difference though. U6900 1 3.42 2 0 3 0v 4 2.86v 5 2.83v off 2.85v on u6901 1 2.33v 2 2,33v 3 0v 4 3.43v 5 3.43v

Ok done 16.6v stable when greenlight and fans spinning then 16.9v when greenlight goes off. Couple of other things I just ran ASD and fails the sleep test, ASD gives error 'no override file detected, please flash before running diagnostics'. Also no serial number when osx is loaded so bios...

I'll check now. Genuine charger though I've used it with other laptops as its my own so quite sure its not the issue.

Ok so I have a liquid damaged 820-3330 it’s been worked on previously as I found out further into working on it. It starts with a charged battery but with a charger will get green light but power cycling with fan spin and green light going off then coming back on and fan spin/green light. I’ve...

Ok changed Q7030 and Q7035 and both getting super hot. Source links here cpc, rs online and other electronic suppliers dont seem to sell them in the UK i could only find ebay for single components in france with expensive post...

Mac is powering on with the correct 85w charger obviously hadn't checked the model when I was busy doing a u7000 for first time :( Ok got another 2011 macbook with a faulty GPU but working charge circuit and took some multimeter readings of Q7030 and getting 45 ohms between pins 1-3 and 4...

Ok I replaced u7000 I get greenlight now but no charging and no red light. Power off battery still works and OSX says battery not charging but coconut battery shows charging at 19.12 watts(its not charging).

I didnt notice you were admin either, thanks took a while to activate ended up scrapping that last board. Is there nothing else that can cause u7000 to heat up like that? I dont think I'm capable of getting that soldered back properly.

Can't say on that I just found a short on c7000 and c7001 after removing both caps(and losing one) the pads are shorted to ground. Also R7051 measuring 43.2ohms not the spec 2.2ohms. Update saying that r7051, r7052 and c7050 all showing 43.2ohms

As title says I was having screen flickering issues so sprayed isoprophyl on the display connector, now theres no green light. Laptop works fine from battery power I already went through a schematic and found R5311 to be only 67k but seems suspect as if the schematic is wrong(going to order...
