Question about Microsoft Natural Ergonomic 4000

1 Answer

When I type a 5 it puts 5/ and it opens Internet Explorer by itself

I have a Microsoft Natural Ergonomic 4000 Keyboard. When I type a 5 it puts 5/ and when I type % it puts %|. It also opens several Internet Explorer by itself, I do not know if it is a particular key and if it is I don't know which key. It is about 2 years old and did not give me any problems until about 10 days ago. I have installed the latest software from Microsoft and reset to the default, but it didn't help. I changed computers and it still does the same thing. I put a different keyboard on my computer and it works fine.

Spacebar on my Microsoft Natural Ergonomic Keyboard 4000 is sticking in the down position.

Take out the space bar button and change the position of the "sway bar" shown in

There are 3 positions you can keep the sway bar - The middle positions worked for me and probably will work for you too.

Hi there !

The best way to clean or repair your keyboard is by removing all the screws at the back of the keyboard. And you can clean that chip board and all the buttons as well.

There is software required for this feature. The keyboard should have come with a disc. You should also be able to download it.

My Keyboard won't type on Word program.

It seems like your trying to type into a locked document, which means that your keyboard is working, its not the issue, the issue is the spesific file which is locked, try another document / file or turn off the lock from office settings if you can find it.

I don't think they sell keys, take one from another keyboard or replace the keyboard.
