Hello All, My Rat 9 Wireless Mouse will not switch on. I've done a deep cleaning, just short of totally disassembling the entire innards, to get at the power switch. On my spare Rat 9 I totally dis-assembled it and, was hoping not to re-live that experience. Batteries have full charge, Latest drivers are installed, and PC was re-booted. I can't find a single post online regarding this event (Wireless Rat 9 power switch issue). Running Windows 7 Ultimate 64 Bit.Thanks for reading.
