How do I see that caps and numbers are locked for the Logitech MK250 for Windows 7. Many thanks

You should have software that comes with this combo. SetPoint 6.0 is the latest at the moment, and once installed and updated will show on screen if caps lock, num lock, function key's are active!

How to know the Cap Lock is on or off for my Microsoft wireless keyboard 4000?

I don't have one of these keyboards, but there is usually a small led built into the caps lock key to indicate the lock is on, Push the caps lock key, and observe if any leds are changing state. If they are, it's the indicator led.
Otherwise, you will have to open Wordpad and see the state of the key. It's possible the led isn't working, so check it's state in Wordpad.
Good luck, and hope this helps.

A = Cap locks On= Cap lock is on. Off = Cap lock is off.
F = Function Key usage. On = I'm going to use the alternative fuctions of the F keys as programmed in the Keyboard settings. Off = Your using the standard features of the F keys.

Microsoft 4000 wireless keyboard is not working

Look under the wireless keyboard. There is a door to install batteries. It sounds as though you just need to replace the batteries on the keyboard. I think that they're AA.

Good luck!
