Dell Inspiron 3148 Keyboard Replacement

はじめに

This guide is intended to demonstrate the removal and replacement of the keyboard in the Dell Inspiron 3148. The procedure may be missing some steps. In Step 21, most of the components have been removed from the keyboard/case assembly. However, the speakers and trackpad still remain, and can be replaced on the keyboard/case assembly if salvageable. Furthermore, it is possible the keyboard can be removed from the case and replaced independently. If you find this to be the situation, consider revising this guide to include the additional steps. Thanks!
