Introduction

Audio buttons not working? This guide will help you replace the button board of the Bose SoundLink Mini II. In order to replace these parts be sure to have the necessary tools that are required and the replacement parts. Use caution when working with a charged battery while removing the circuit boards.

Note: This procedure requires removing and reinstalling the battery, which requires the use of a soldering iron and/or a lot of careful disassembly.

    • Carefully lift the battery from the side nearest the four gold contact pins, but don't try to fully remove it yet.

    • At this point, the battery remains connected via four wires to the power supply board.

    • Carefully desolder the four wires from the power supply board in order to completely detach the battery. There is very little room for the soldering iron without damaging the case or the board; you may want to remove the board first.

    • For help with soldering, see the soldering guide.

    • Alternatively, you may remove the battery and power supply board together, without any soldering, but access requires some additional disassembly while carefully leaving the battery connected via the wires the entire time.

How do you put the rubber cover back? - the tongue, the one in the corner near the charging port, doesn’t want to go in.

Hi,

What you refer to as the ‘side board’ under step 10… do you know where I can buy one of these from?

Thanks

Steve.
