Re: apple magsafe 60/90W schematic needed
Hi
I don't have the schematics but I would like to share some photos and information about repairing a 85W magsafe died due to power surge...
My Mac Book Pro charged exploded with a loud sound and smoke. I decided to open it and fix it. I read online a wonderful method to open these kind of adapters. After a visual inspection i found out that the black soot have covered all the damaged area so I cleared it with damp cloth and luckily i was able to read the values printed on the dead components.
These components are connected like this
Fuse in Plug -> Varistor->Sidactor(Thyristor)->Fuse->(unkown circuit)
BS1362 3A ATLAS Fuse ->TVR 14271 -> p1300ec ->T3.15A 250V square fuse
With the help of my elder brother i was able to get these item from local market i changed these items and now my charger is working fine.
Replaced with
BS1362 3A Bussman Fuse -> ZNR14K271U -> p1300ec -> T3.15A 250V square fuse
This sidactor (p1300ec) have a capacitance of 0.054nF. (test tip)Comment

by ThetechdudeHi guys, I'm working on a MSI Ventus RTX 4080 16G. The GPU has 12v, 5v, however what I assume is the 1.8v rail has 1.1v and what I assume to be PEX is 0v. As you may have guessed already there is no Vmem and no Vcore.
I have looked around in related forum posts for a schematic so Much appreciated if anyone can share a Broadview schematic.
Thanks.-
