Re: my mouse works fine, but keyboard will not function...
that you have good batteries installed, turn the Keyboard over and locate the
small reset/connect button on the back of the keyboard and press it. Then
try to see if it is working. If not try pressing the button on the
receiver and then on the keyboard. Try typing, should work okay.
this helps. Bud

I'm going to need even more information; The devices that use PS2 connections, which device is it, and how many of those devices do you have?
One thing that might be a problem, if the issue you see is intermittent, I would check the PS2 connector and see if the pins are bent or broken. PS2 connector pins sometimes will bend or break and this can cause some connection issues if not completely stop the keyboard/mouse from working... Also given the age of your PC the PS2 port may just be bad, but this is not a fatal injury to a computer.
Replacing the Keyboard and Mouse with a standard USB keyboard and mouse, should resolve all of your issues.
PS2 is an older technology that keyboards and mice used to run on; Now however USB connections are used.
Further more, if this an HP Desktop with 2 USB ports on the front, and 4 USB ports on the back, you will want to avoid using the 2 USB ports on the front, especially on older HP and Dell Desktops, the reason is the power supplies often do not have enough power to run multiple USB devices on the front USB ports.
The back ports should be fine regardless of the number of devices.
its hardware problem, may be water or any liquid get inside and make the keyboard not work state, do you have any function key to disable keyboard or mouse mean go to control panel -> hardware setting check whether mouse was disable or not, if it disable mean make it enable so that your mouse works good same for keyboard.
>when wireless keyboard or mouse runs out of battery, you need to re-establish the bluetooth connection in order for them to be functional again. To do so, you need to press the connect button on the keyboard and the USB dongle connected to the computer at the same time for about 8-10 seconds to establish connection. After that, you can try typing again. Same thing applies to wireless mouse.
You should check the connection of you mouse and keyboard to see if they are properly connected.If the connections are okay you should go to the manufacturer website and download and install the drivers for the mouse and keyboard,i cannot give you the link because i am not sure what type of mouse and keyboard you are using.
If you are using wireless mouse and keyboard you should replace the battery inside both of them and make sure the receiver is turn on.After you try these solution your mouse and keyboard should work fine.
I was just about to post that I have the same problem (keys not working on Y-RR54 except scroll, F Mode, etc.) But as I was posting, my keyboard started working. Here's how:
Keep your Y-RR54 connected and hook up another keyboard. WIth the other keyboard, go to Logitech.com and go to their Support section. Select your product (Keyboard and Mouse Combo -> LX700) and then go to Downloads. Download the latest Logitech Setpoint software and install it to your machine. Make sure the Y-RR54 is connected to the receiver before you install. The latest version as of this message is 4.70.213. Let it go through the install, and when you get to the program, click "My Keyboard" and it will make you go through a "Secure Connection" process. After this process was over, my keyboard worked just fine. I'm typing from it right now.
