logitek wireless keyboard problems

That cup of coffee all over the keyboard will do it every time ....

No, but seriously, how old is the keyboard? They are "expendable", either the keyboard goes or the wireless dongle goes?

Is it a Unifying Receiver dongle? In which case you may only need to buy a unifying compatible keyboard (although here in Australia, frequent sales make a whole desktop set just as cheap as a single keyboard).

I'm on my 3rd Logitech desktop set ... only problem is it's always the keyboard. I've got a drawer full of working mouses!!

EDIT : Just checked, don't think the MK320 set is unifying receiver compatible.

Try it out on another computer. Same thing happens?

Check or change the batteries and check there is a clear path between the receiver dongle and the keyboard. I put the dongle on a USB extension lead and stick it to my desk behind the monitor so it is close to the keyboard.

Hello @ils,

An hour ago, my logitek wireless keyboard MK320 began making errors. For example, I hit the 'u' key and '4u' appears. I hit 'e' and my firefox browser opens. I've rebooted, unplugged and plugged in the USB wireless, checked that I'm using a US Keyboard. Nothing changes. Any suggestions?

It could be that the driver has become corrupted!

Can you please perform the following [ this checks for ANY Problem Device Errors ] . . .

[1] Goto this TenForums link => Batch Scripts / Programs.
[2] Goto the heading Find ANY Problem Devices . . .
[3] Download and Run the .bat file.

If there are ANY Problem Device Errors it will create a Prob_Devices.txt file on the Desktop!

[4] Upload the results => How to Upload and Post Screenshots and Files at Ten Forums.

I hope this helps!

1. I plugged MK320 keyboard into another computer; same problem.
2. I plugged another wireless keyboard into main computer; it worked fine.

If you tried the keyboard in another PC and you're getting the same issue, no need in chasing driver or software issues since the issues seems to be the keyboard.

BTW, I've several Logitech wireless keyboards and mouse using both Logitech Options and Setpoint software.

Thanks for the suggestions. I tried them all; none worked:
1. I plugged MK320 keyboard into another computer; same problem.
2. I plugged another wireless keyboard into main computer; it worked fine. The dongle was in the back of the computer, and the keyboard was 10 feet away from the computer.
3. I changed batteries; same problem
4. I ran Find_ANY_Problem_Devices.bat A minute later I got the report 'NO PROBLEM DEVICES WERE FOUND!'
So, it's definitely a keyboard issue and not a computer issue. The keyboard needs to be reset.
How to reset logitek wireless keyboard MK320

It's might be time to replace the keyboard. Is it under warranty? If in the UK you have up to 6 years in consumer law to claim a refund or part refund or replacement. You could ask Logitech support for ideas.
