My keyboard is "dead"

[PeggyJane]

Recently my keyboard just up and quit.  I run Windows XP.  I have a Logtec wireless keyboard and mouse....the mouse works fine...the keyboard will not.  Changed the batteries.....checked the connections...now what?   Thanks to any help.  Peggy

Check and see if that wireless reciever has a channel selector...some do. The keyboard needs to be on the same channel as the reciever.
Also with Logitech's when you change the batteries there is a "connect" button you need to press after a change to re-orient the signal.
