Acer Chromebook cb3-532-c47c Keyboard / Palm Rest Replacement

简介

Many Acer 15" Chromebooks use the same keyboard, including the C910, CB3-431, CB3-531, CB5-571 and possibly others, although the palm rest assembly is the same only on the CB3-531.

There are new keyboard-only replacement parts for sale, but using them requires melting off or otherwise removing the head of approximately 58 plastic retaining pins, then figuring out how to re-secure them. That kind of replacement is beyond the scope of this guide, so we'll only be dealing with a replacement that comes with a keyboard + palm rest as a single unit as pictured above.
