Wireless keyboard not working on Touchsmart 520

[MikeC1945]

Keyboard quit working on my Touchsmart 520. Have changed batteries and have tried to re-sync. Have moved USB dongle from rear slot (behind cover) to another open slot - blue light flashes and computer beeps when I do this. But still cannot get computer to respond to keystrokes (nothing appears on monitor when I press keys). Any suggestions to fix problem are appreciated.

Use Device Manager in Windows to check for and install any driver updates.

1. In Windows, search for and open Device Manager.

2. Click the arrow next to Keyboards or Mice and other pointing devices to view the currently installed devices.

3. Right-click your device, and then select the option to update the driver.

   On the Update Drivers screen, click Search automatically for updated driver software.

4. If an update is not available, continue to the next step.

5. If an update is available, update the driver, and then test the device. If the issue persists, continue to the next step.

Reset the device connection:

Disconnect the wireless receiver from the computer to reset the connection. Make sure to complete these steps within 60 seconds.

1. Disconnect the USB receiver, and then wait 10 seconds.

2. Reconnect the wireless receiver into a different USB port on the computer.

3. Test the device.

1. If the issue persists, continue to the next step.

Use the HP PC Hardware Diagnostics tool for Windows to identify mouse and keyboard issues.

1. In Windows, search for and open HP PC Hardware Diagnostics for Windows.

   Follow the on-screen instructions, and then review the test results.
