简介
Follow this guide to open your Logitech K540 wireless keyboard.
Opening your keyboard gives you access to clean its internals, troubleshoot mechanical problems, or replace a part.
Before starting this repair, note that opening the keyboard requires removing the Logitech sticker on the bottom—it's very hard to do this without damaging the sticker.
