kann ich mein deutsches Topcase mit einem z.B. UK Topcase austauschen
diese sind leichter zu kaufen und das andere Tastaturlayout wäre auch nicht das Problem
Hallo benny.joos98, es ist sehr wahrscheinlich möglich ein UK Topcase zu verwenden. Frage aber sicherheitshalber noch mal im Forum nach; eventuell hat bereits schon jemand diese Art von Tausch gemacht und kann mehr/genaueres darüber sagen: https://www.ifixit.com/Answers/Device/Re...
