UE Boom 2 Won’t Turn On

If you saw a red light on your speaker before it stopped turning on, your speaker is most likely not charged. Plug the charger cable into the MiniUSB port located on the side of the speaker. Plug the other end of the charging cable into a laptop or the included power outlet adapter, and allow the device to charge for four to five hours.

If the speaker is refusing to charge, it may need a factory reset. Press and hold down both the volume button and the power button for about ten seconds or until you hear the speaker make a sound. After the sound, the speaker should turn off. Now, try turning the speaker on again.

If you have tried charging and resetting your speaker, and it will still not turn on, you may be dealing with a faulty USB port. Try using the speaker’s USB cable and plugging the UE Boom into your computer (note that software may automatically install for the USB connection). Try turning your speaker on while it is connected to the computer, then disconnect the speaker and turn the power off. Then, try turning the speaker on again.

If you have followed these steps and the speaker still refuses to charge or turn on, you may need to replace the speaker’s USB port. Use the UE Boom 2 USB Port replacement guide to replace the speaker’s USB port.

If you have charged the speaker and it still will not turn on, your speaker’s battery may have reached the end of its lifespan. Use the UE Boom 2 Lithium Battery replacement guide for instructions to replace the speaker’s battery. Note that replacing the battery will void the speaker’s warranty.
