OK thanks Duke, I'll give that a go. Yeah I've seen rework stations with heater plates. A bit outside my budget for now, but I can try two guns at once. I've bought a faulty 820-2879 off eBay, which was the cheapest board I could find that I know has the U5010. And the board I got looks to be...

OK thanks JohnB, that's good to know. Duke, yeah I'm going to get a donor board. Can you explain what you mean by bottom heat? You heat from the other side of the board, under the chip, not on top of it? Thanks.

I really suck at this. I've spent ages trying to get this fucking U5010 off the board. I've gone as high as about 350C on the gun and the damn chip just won't come off. It looks so easy in Louis videos, he just waves the gun around and a minute later the chip comes off. I tried putting flux...

OK, so I guess it's worth trying removing it from the board, cleaning the pads and putting it back on? I see I can buy replacements from Louis or from China, but both involve international shipping so I'd like to see if I can get this one working first. Could you just confirm I'm OK to heat up...

OK, more confirmation of the 0.9V reading - I measured each side of both C5025 and C5026, marked PP3V3_S5_AVREF_SMC and GND_SMC_AVSS. I also measured them between their PP3V3_S5_AVREF_SMC pin and GND. The highest reading I got was 0.9276V

EDIT: sorry, ignore this post, I misread the schematic.

I notice that the area around U5010 looks pretty bad, and pin 8 looks a bit different to the other pins - not a great connection maybe?

OK thanks. I've taken a measurement and if I did it right, I'm only getting 0.9V. EDIT: I think this is a valid measurement, as I've measured it as 0.9V elsewhere too. This is what I measured, with the motherboard powered but not turned on: EDIT: I just measured again, this time between...

Thanks for replying so fast. OK I've tried that twice, but unfortunately no luck. Specifically, I first ran the gun at 150C for about 4 minutes all over the SMC, including angled in around the edges. Tested, same errors. So I tried one more time, this time around 190C for another 3 minutes or...

Hi all, Thanks to Louis for his great videos and this forum. Firstly, let me say that I am not a repair shop. I'm just trying to repair a single MBP 13" late-2011 that I bought cheap with a known fault, hoping I could repair it. I've spent more than a week on this, hoping to fix it on my own...
