    Hello all. I have a question for you, I have a Bose Soundlink color speaker that does not work, namely. After turning on, detecting the device via Bluetooth and pairing, the speaker does not show any signs of life. I read on the forum bose that when it is unused for a long time, it must be restarted, which I did, unfortunately it did not help at all. Then I undressed this speaker thinking that the battery is for replacement. The battery voltage is 3.7 volts. My question to you is what I can do to help me repair this speaker?

    It is also worth checking if there are sometimes cold solders.

    The loudspeaker, after correcting the soldering points and slightly pressing the plate, started. Works :) just what the LEDs have turned off since turning on and switching between bluetooth and aux

    He is, but he does not want to look more. Even after entering the type of link in Google, we receive information.

    Hello!

    Do you know if this device should turn on without battery soldered on?

    I have a BOSE Soundlink color 2 drawing 210 mA for 1-2 secs and then 0.
    I have opened it, removed the battery. battery had 0v.
    tried to charge it with power supply, dead.

    Now I would like to know if the speaker should turn on WITHOUT the battery in place.
    Mine takes 0 amps without battery and nothing happens when turning on.

    Any hints?
    Thanks
