Re: APPLE A1425 820-3642-A Schematic



OK. It's even more interesting. Tried to boot from USB installer when I finally could turn ir on again and it didn't turned off - I could reinstall os without problems till final boot, when it turned off in final stage. Tried to boot normally, but it turned of in final stage again. Then next time I booted in safe mode and it booted up successfully. CPU was still too hot, but macbook didn't turn off. Installed updates and now its off again. Maybe there is some failed device USB controller, CPU/GPU, thunderbolt etc., that's not...

Hi. Thanks for schematic and board view.

I have a macbook A1424. I don't know a history of it, but I got it dead at all without visible water damage, with broken screen connector which I replaced, a broken IO board connector which I repaired and missing zener diode 6.8v D6910 which I replaced with 6.2v for testing as I had it already.
When I plugged a charger in - green light came up, then it turned orange. Only a fan started to spin for about 3s, then stopped...

OK. I'm living in small country in Europe. I like Apple goods, but there is no apple service at all - only an Apple store, where they don't know how logic board looks like.
First computer was Pentium 200MHZ MMX with 64GB Ram and woodoo banshee graphics. It was gooood.
Now I use a self made iMac 5k (i mean made by original (maybe) parts)
