I picked up a K70 keyboard at the thrift store, and I've been happy with it. I've given it a good cleaning (taking the keycaps off, etc.) and there's no sign of damage. I've only used it for basic typing, and none of the advanced features. All the keys are lit, and the basic keys work. Multimedia controls don't work, but volume up/down does. I've got no idea what the keys on the top or the "BIOS/1/2/4/8" switch does.
Since it's from a thrift store, I can't look at the box, or ask the previous owner what it is. The label on the bottom is worn off, so I can really only tell it's a K70.
I'm looking into these things now but I can't get iCUE to detect it. I also can't find even a basic manual on Corsair's web site. Trying the keyboard reset methods doesn't seem to work either.
Can someone tell me what this is? Any ideas why it's not showing up in the iCUE (or the older Corsair Utility)? I've restarted the HID service for the multimedia keys, and no luck with that either. Also, I'm wondering what the keys on the top are for. (Or a link to a manual would be nice)
Edit:I'm not sure why the images aren't embedding. Here's links to the top and the bottom
