Try this first, if it fails, return it, it is covered under warranty.

1. Make sure your speaker is plugged into a working AC socket.

2. Check the connections between your speaker and the power adaptor.

3. Make sure you are using the power adaptor supplied with your speaker upon purchase.

4. If you are using a surge protector, check to see if it is working properly.

5. If you still cant get your speaker to turn on you may have a faulty power adaptor.

6. If your speaker is not charged or used within a 14 day period it with enter protection mode. Connect the speaker to the AC power adaptor to fix this issue.

7. Make sure the battery has sufficient charge to power on the speaker.

Blinking Red indicates charge is needed. If the battery is drained it will continue to blink red while charging until there is enough charge. I would let it charge completely before trying to use it this time until the battery light turns green indicating battery is fully charged. If needed, you can do a SoundLink speaker reset, following these steps:

- On the speaker, press and hold MUTE for 10 seconds; the LED will flash briefly

-Press Power to turn the SoundLink back on

If either of these answers do not help, you may need to exchange it. Good Luck and please let us know... John

This is a bug with the firmware where the battery seems to get locked in low power mode if it runs down too far. I had this problem and tried every suggestion found online with no success. After much back and forth with BOSE support, the following finally worked:

1. Plug your speaker into a computer using the USB cable.

2. Go to in a browser window. Download the software if you don’t have it and launch it.

3. The webpage should change to show it has launched. If it says there are updates available then choose to install them. This should fix it.

4. If it says the software is already up to date, then press the following keys in order: A,D,V,Up arrow, Down arrow. That should now give you the option to downgrade the software. Choose a downgrade and then Apply Changes.

That is what brought mine back to life. You can upgrade the software again after that.
