Encountering power issues with your Bose Soundlink Colour speaker can be frustrating, but with methodical troubleshooting steps, it can often be resolved. Start by examining the power supply as a potential cause. Connect your speaker to a known working power outlet. To ensure the outlet's functionality, try plugging in another device. If your outlet is alright, assess whether the USB charger meets the speaker's power requirement. For optimal charging, use a USB charger with a current rating of at least 1 amp or higher.
Check the Power Supply
Begin by examining the connection between the speaker and its power adaptor. Make sure that you are using the official Bose power adaptor and that all connections are secure. If the speaker is connected through a surge protector, verify its functionality.

Inspect Battery and Charging
If the Bose Soundlink Colour speaker's battery is fully depleted, give it adequate charging time based on your charger’s output. High-output chargers (3A) require less time, approximately two minutes, while lower-output chargers (0.5A) could require an hour or more. Take note of the charging light indicators: the charging symbol blinking orange three times before turning green might signal charging problems.
| Charger Output (Amps) | Estimated Charging Time |
|---|---|
| 3A | Approximately 2 minutes |
| 1A | Approximately 30 minutes |
| 0.5A | 1 hour or more |
| Note: Charging times can vary based on the initial charge level and battery health. | |
Troubleshooting Steps
Consider resetting the speaker if it fails to power on. Avoid holding the power button when switching the speaker on or off, as this action might inadvertently check the battery level instead. A soft tone from the speaker when connected to power can be a clue – if the tone is absent, recheck connections.

If the issue persists, update your speaker's firmware to access the latest features and fixes. This can often resolve power-on problems. Placing your speaker into 'Ship mode' might also help; follow your speaker's specific instructions to enable this mode and then charge it for at least an hour.
Additional Considerations
In rare cases, if the speaker has been unused for extended periods (beyond 14 days), it can enter a protection mode. Connecting it to its AC adapter typically resolves this. Always ensure that your speaker has enough battery charge to power on. With these strategies, you can diagnose and potentially fix power issues with your Bose Soundlink Colour speaker, enhancing your user experience.
