    Most E-cigarettes use lithium batteries - which are pretty dangerous if you don't charge them exactly as specified - they can vent with flaming gas and set fire to their surroundings!

    If your skill level is such that you glue wires back on instead of soldering them - I seriously advise you not to put yourself, family and possibly neigbours in any further danger, stop messing with it and buy a working replacement.

    Hi, i just "soldering them" and now is working, i'm not an expert but i can handle this, i can replace different circuits parts, but i need to know what is not working.

    Where is the LED located and which wire is leading to LED?

    Do you have a multimeter? You can get one very inexpensively (<$5 or even free at Harbor Freight) and you will find it useful for many other chores.

    Those broken wires need to be re-soldered to the printed circuit board (PCB) but from here it is not obvious which wire goes where.

    Oh wait, I just read your later posts, that you have already re-soldered those wires?

    You may need to get to the backside of that PCB, or at least get under that diffuser (refractor) to see the LED underneath. You MIGHT be able to see the leads for the LED under the plastic, and probe them with a multimeter to see if there is voltage. In that case, it's simply a burned-out LED.
