ive been using deathstalker v2 pro tkl keyboard  for about 5 months.

and recently it started to get disconnected when i leave it alone for a while.

And now im experiencing a problem that i cant turn it on even if i move the switch to 2.4 or btmode. its like completely dead. i also tried plugging it to my labtop with c to c cable and the power indicator light beside the 3 pairing buttons but it doent even light up as if its not even getting charged. 

is there anyone experiencing the same? should i get a replacement?
