Hi,
One or two weeks ago I started to use R6P batteries 1.5V AA on my mouse. But today, the mouse just stopped working. On Razer Synapse, it doesn't matter if I change the battery, it is always empty. I’ve tried factory reset, uninstall drivers, uninstall all razer products and install again and nothing worked.

I saw a similar topic with the AAA batteries problem:
What should I do? Any ideas?
