Got an A1534 2015 edition with 250gb SSD and whilst the SSD is detected in internet recovery and also in my test external ssd with mac os it's reading as read-only and I cannot erase it, format it or partition it. I'm presuming this is a dead SSD and assuming this is there any possibility of...

Thought so thanks - they'll just have to use it on external monitor only then!

So i've got an 820-01521 in today from a Macbook Air which was water damaged. Fixed the short on ppbus which was preventing it from turning on, it switches on now and works on external display but nothing on the internal screen. The LCD connector is clean and no sign of liquid there however Pin...

As a further update to this I couldn't find any on the boards I had. I've tried NCS214 which does work just the same and I also had to replace U5410 which I replaced with NCS210. So for future reference you can replace INA214A with NCS214 and INA210A with NCS210 providing you buy the correct...

I'll have to have a look through them - I think I only have one post 2016 scrap board which was from a non touchbar 13 inch. I'm guessing the non type c boards are a no go? I've got a fair few 820-00165, 820-3437 and 820-4924 boards. This is the first 16 inch one i'm seeing - you gotta love...

So today I received in an 820-01700 from a Macbook 16". Is liquid damaged but only in a small area of the board around U8400. I've found U5450 is completely burned to the point that even the traces on the board aren't there and will need to be repaired. That being said does anyone know where I...

Gave up with this and got the customer another motherboard for $150.

there is no USB activity in SMC Bypass mode = also no display and no more diagnostic LED's light up. I'm getting 15v on the gate pin of Q7950 (tested at U7950) and yes there is stable PP12V_S0 in smc bypass mode.

Actually I don't think it's Q7950 - I did try the SMC bypass mode and got the fan spinning on full and the voltage output of Q7950 was 12.2v on PP12V_S0 - that should indicate Q7950 is working?

I can try that but I cannot find IRF6892 from a reputable supplier - is there an alternative available?

Got an 820-3302 today - won't start up - there is one green diagnostic led - when I press the power button the fan spins a little then stops - no activity on any other diagnostic led's that I can see. Nothing immediately visible i'm wondering if this points to a PSU issue?

Thought i'd chip in here as i've been trolled by these before - if either U7100 or Q7130 has or had a fault they will tend to burn the other one. So if you had a short on U7100 then you need to replace Q7130, if you replaced U7100 without replacing Q7130 you have probably killed the new U7100...

Hi Thomas yes just replaced U7310 with FDMF3030 fixed the issue - i've cinebenched it several times since replacement and no more shut down.

Just to report back on this for future reference - FDMF3030 works fine as replacement for the original FDMF6708N recommendation. Got mine from mouser!

Certainly looks like it from the datasheet - I shall order a few and try them!

Received a Late 2013 Retina Macbook Pro 15 inch today. It's randomly shutting down which I have replicated. I've read around and i'm seeing U7310 listed as a common failure point on these boards. The only issue i've got then (assuming correct diagnosis) is that I cannot find the recommended...

tried this and unfortunately the behavior is the same. Any further ideas on this problem?

Do you have a link to a known working clean ME BIOS for this board?

Unfortunately I can't as it's completely broken the windows install now.

I believe it was the Intel SYSTEM driver as listed on windows update,
