MK300 Logitech Keyboard dead!!! (mouse is OK)

I was sort of happy that it decided to suddenly stop working. Nothing wrong with it, but a little troubleshooting for me.

After plugging in and unplugging the receiver, the keyboard had no response to anything.

I put in new batteries. Still nothing.

I held the receiver for 10 seconds to reset it. Still nothing.

I uninstalled and reinstalled Setpoint, only to see that there is no keyboard tab. Still nothing.

The CTRL (left) -ALT (left) F12 (once or twice the key combination) - connect Receiver, connect keyboard and then ESC. Still nothing.


For some odd reason, connecting the receiver to USB 1.1 port (probably unrelated) and holding in the connect button while inserting batteries, seemed to have fixed the problem.

I noticed as a red bar appeared in the bottom of Firefox - Search as you Type, for the random keys that were pressed when I did that connection test!!!

UPDATE : it is inconsistent - the keyboard died again. It worked on the same computer in safe mode, they stopped - again. I looked up the EEPROM Amtel 25160AN found in the receiver- but I do not want to mess around with it more than I have to.
If you are still under warranty - contact customer support if you cannot get it working again!

Update :
I booted off Puppy Linux : mouse and keyboard worked fine. It is obvious there is problem with Windows and how it manages the drivers. Why won't Logitech make software fix for this?
