Hello,

Its a hardware (battery) issue. Unboxed the mouse and found battery leakage. Even after cleaning and trying with bew batteries the red LED is not glowing.

@user_0aa41a​  Well if the mouse in warranty you can have a replacement of the mouse.  

Where do I take it to get it repaired if its under warranty?
