Logitech K520 Installation Help

Hello! I've never owned a wireless keyboard and mouse before. So I just got this to upgrade my wired mouse and keyboard. So straight away I plugged in the dongle, pulled the tabs on the batteries, switched them on, and nada. The mouse moves very jerkily and the keyboard turns on then turns off. I checked the batteries, all three are in the green on a battery checker. I've run the Unifying software and it can't pair the keyboard so it will start to work. Admittedly the wired keyboard and mouse are still plugged in and I've not rebooted the computer yet. I really really *really* hate to reboot the computer unless i really really *really* have to, I tend to treat my system like a server in that respect. And I was keeping the wired versions plugged in until the wireless ones are running just for backup like now I'm using the wired keyboard to type in this message and such. So, do I have a bad pair of devices and need to send them back or ... ?

Oh! And the computer isn't that far away neither, I can reach out and pat the top of the case so it's close.

try them in a different usb port and maybe directly to the unit if its in a hub of some sort as could be power related. A reboot shouldnt be required tho for usb mouse and kb's.

@Bastet Opps! I switched them on even before I installed the Unifiying software. Though when it said to switch *off* then switch *on* the device I was trying to pair, which is the nonfunctioning keyboard, I did so and it failed to pair. So now what? O.o

Ok, I installed the Setpoint software, latest for Windows 10 x64, and they keyboard maybe works. It's behaving like the mouse, very very *very* laggy. Type something and nothing appears for quite a bit. The mouse was the same, wiggle it and nothing for a few seconds then it would work a little then stop for a little, etc. O.o I typed "Test" and only t appeared after a few seconds then nothing.

Something is really weird here. O.o I am going into the Unifying Software Advanced View, it lists the keyboard and mouse, and even though the keyboard is switched on, the software lists it as Inactive, unknown battery, and unknown firmware version. O.o

There we go, bleh, I had to move the dongle from a back port to the front panel. That's going to be annoying. Oh well. Thanks all!
