Connected to new computer, new batteries in keyboard and mouse with no connection, pushed connect button to both but does not work


Seems to me that if i remember right there should be three (3) pieces to this system. The mouse the keyboard PLUS the wireless interface that connects to the usb port. This has to be connected for the other two devices to connect to the computer and work
Find the third piece and you should be OK top go
Hope this helps

My keyboard froze up and the mouse still works. i


check for corrosion/moisture inside the keyboard either on the little circuit board or depending on the way your keys interact in the check to see if there is moisture in the workings of the board, also make sure your keyboard circuit board is securely plugged into the interface jack(the plug inside the box not the external one for the computer)<G>

My Microsoft Wired 600 keyboard has suddenly malfunctioned and the keys "1" "Q" "A" and "Z" (as far as i know these are only ones) just wont work anymore, help?


Well, it's in a bad shape, but if you still wanna fix it, try remove all the nuts, then see for the rubber connector inside it, clean it with soft cloth and alcohol, then on the electronics board, clean it with it too.

Also recheck the PS2 connector ( if using PS2 ), sometimes this cause the problems.

Wireless keyboard problem


just called Logitech support (who were more than helpful, very friendly, and picked up the phone within 5 minutes).
I have an MX3000 laser combo set and the receiver lost connection to the mouse last week. Then the keyboard went out a few nights ago. I had tried what everyone else here had tried to no avail.
So I decided to give a tech support line the benefit of the doubt and call one...
I'm very glad I did!
Here is the entire process for the Left Ctrl + Left Alt + F12 keys. First, when you hit these keys together, a box should pop up on screen to prompt you to reset the encryption sequence. That is what these keys are for. If nothing pops up on your screen (as was my case!), wait a few minutes for the button sequenece to time out, then hit these keys again. Make sure its L-Ctrl + L-Alt + F12 only. Within 2 seconds after that button combo, hit connect on the receiver. Within 2 seconds of that hit connect on the underside of the keyboard. Within 2 seconds of that, hit your Escape key on the keyboard. Sounds completely ridiculous, but this is the direction Logitech support drove me in. And it worked for me. And this is after I tried everything imaginable for over the past week.
We then moved on to the mouse, which i thought we had fixed. But now i have one working and one not working, so I think I need to re-run through this whole process to fix the second mouse. Basically, I now have 1 mouse that works on both receivers, on 2 different pc's with 2 different keyboards in two different rooms (both sets are MX3000 however).
The other now seems to have lost the signal. Will update if I get that second mouse to play nicely with me.
Hope this helps anyone about to trash a perfectly good unit like I was!

Keyboard won't work


I have had problems similar to this B4, it seems that when ya use a Wifi Key board some software "locks out" any other keyboards via the PS/2 interface.. I got a work around by using a USB Adapter and plugged my "Other" keyboard into a USB slot & could then use both, but not some features of it. So then later, I then got a "Real" USB keyboard and was able to use all the "Features" it had.
