Sounds like your keyboard sometimes reset itself, maybe you need to replace the battery's on the keyboard.

My bluetooth keyboard light only illuminates upon initial connection establishment. The first time I strike a key following re-boot or sleep, it illuminates but nothing further afterwards. I was puzzled about this myself at first, but my research tells me this is normal operation.

 

The blue light on your physical on-board bluetooth controller should remain illuminated whenever the computer is on.

You are right but I don't know how to make the thread show the Prob Solved icon. Talking with a Dell tech today about other probs and the light will only show momentarily a Bluetooth connection being made if the pc doing a new start or such. I was just expecting the light to show full time (like my W98 W-xp keyboards) if the Locks are ON but thats not its purpose.

Thanks to you all who respond.

When the batteries went dead in my keyboard, I replaced them and now the blue light stays on, but will not connect. The connect to bluetooth reset button has no effect. Anyone have a similar experience?

the problem i had was the keyboard would stop working, i change the bat. many times and then i replaced the keyboard with a normal one, no more problem.

 

i never figured it out

and i have an extra keyboard.   someday if i ever figure it out i may put it back on but for now this one always work for me... maybe they haven't worked out all the bugs in bluetooth????????
