Ok, really wierd, my desktop (dell inspiron) restarted for some reason, and when it rebooted, The keyboard and mouse were no longer connected. I am using a wireless mouse and keyboard, and the desktop does not have a PS2 for keyboard or mouse. I have taken the mouse and installed it fine on a laptop, so I know it is not batteries or hardware failure of the mouse or keyboard.
How can I Isolate the problem? I cannot get into bios as no keyboard response. It boots all the way into the security desktop, but I cannot log in as no keyboard response. All services still start, as it still hosts my intranet.
Thank you in advance for any direction or advisement.
Please try the below mentioned steps and see if these steps help:
1. Press and release the Connect button on the bottom of the keyboard, then immediately press and release the Connect button on top of the receiver.
2. Wait 20 seconds.
3. Press and release the Connect button under the mouse, then immediately press and release the Connect button on top of the receiver.
Simple steps but need to be performed correctly in order to reestablish the connection successfully.
NOTE: before trying to sync or re-establish the connection, change the batteries on the wireless keyboard and mouse for better results and to save time.
If the issue still persists please reply with the exact system model number of your Dell Desktop.
Sorry for the delayed response. There are two front panel and four back panel USB 2.0-compliant connectors on Dell Dimension 3100 / E310 desktop. Have you tried the USB Wireless receiver in different ports? When connecting the wireless receiver to other USB ports do you hear the windows sound for new hardware detection? If you can arrange for another USB Keyboard and mouse, please try connecting them to the computer to identify if the failure is with the USB Ports in the machine.
