Product will not turn on

If your product appears to be receiving power but won't power on as expected:

Update your SoundLink Color II speaker with a computer.

Bose has identified a software bug present in an earlier software version of the SoundLink Color II. This bug prevents the speaker from powering on or charging when the battery reaches a deeply discharged state. Software version 4.0.1 has been deployed to correct the bug and allows the SoundLink Color II to charge and power on even if it is currently not doing so.

Please visit btu.Bose.com, download the Bose Updater program, and follow the instructions to update your speaker.

Important: Once the update is complete, the product should provide some LED feedback. Please allow your speaker to charge 100% prior to using.

How are you charging the speaker?

Wall outlet

Computer USB or other USB power source
