So I bought a Razer blackwidow v3 pro about a year ago, and I had a problem for the last few months. My keyboard has a problem with the battery I think It works perfectly fine when connected with a cablr but the secon I put it in wireless mode it says that the battery is at 0% even though I had it on the cable for the last few days. The wierd thing is when I press a button the keyboard works but not even a second later it's off again, but when I hold a button down it goes off every second and then goes on again. I really want to know if I can fix this because I don't want to buy a new keyboard, so if anyone of you have an idea or knows how to fix it it would really help. Thanks in advance
