i have a Microsoft Wireless Entertainment Keyboard 7000, this is a bluetooth keyboard and made by Microsoft. i have successfully used this keyboard for over a year, now it has decided to stop working. it still works in BIOS(i believe its called) but not in vista itself.(this means that the batterries and bluetooth connection are fine) i now have an older keyboard plugged into the keyboard input which works fine, this is i believe a PS2 port? this is as far as i am concerned a software problem, any help is greatly appreciated.
