I bought a Deathstalker V2 Pro TKL a 3 months ago.

Yesterday my battery life turns 0%. 

As I usually do, i put my USB cable to charge him.

When i woke up and remove my USB cable, i noticed my keyboard doesn't turn on.

I put again the USB Cable and in the Razer Software (synapse 3.0) my battery life is 100%. When i remove the USB cable, pops up a message: "Deathstalker v2 pro TKL has no baterry life" Something like that and my keyboard turns off.

Is bizarre i pay expansive to this keyboard to doesn't work.
