简介

This guide is intended to replace the power switch assembly in the Marshall Stanmore II Bluetooth Speaker.

The power switch turns the speaker on or off while it is plugged into a wall outlet. Over time, the power switch may break or wear down after normal use. This renders the speaker inoperable.

Before using this guide, ensure the speaker is plugged into a working outlet. This can be verified by plugging another device and ensuring that it works as intended. After verifying the outlet, follow the "Failure to power on" section of the Marshall Stanmore II troubleshooting page.
