GK100F keyboard input problems

[nsityar1979]

it seems when i press the esc button, both esc + f1 keys are inputted simultaneously. Also shift button simultaneously pressing shift+tab keys. Wait, but there is more problems in my keypad, but will leave it to you what solution you might provide.

P.S. 

I cannot seem to verify the serial number of my product in your website: GK100F231212024

Thank you in advance,

Hi @nsityar1979,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The issues you're describing suggest a hardware or software problem with your GK100F keyboard. Below are steps to troubleshoot and potentially resolve the problem.

Check for Software Conflicts

• Test on another computer/device: Connect your GK100F keyboard to another system to see if the same issue persists. If it works fine, the problem might be with your current computer's software.
• Reinstall keyboard drivers:
  1. Go to Device Manager (on Windows).
  2. Expand Keyboards, right-click your keyboard, and choose Uninstall driver.
  3. Restart your computer, and Windows should reinstall the drivers automatically.
• Update drivers: Check if updated drivers are available for your keyboard from the manufacturer's website.

Inspect for Physical Issues

• Check for stuck keys: Ensure the ESC, F1, SHIFT, and TAB keys are not physically stuck or sticky.
• Clean the keyboard: Use compressed air or a soft brush to clean the keyboard and remove dust or debris that might cause key overlap.

Reset Keyboard Settings

• If your keyboard has software for customization, reset it to factory defaults. Misconfigured macros or remapping settings could be the cause.
• Some keyboards have a hardware reset:
  1. Disconnect the keyboard.
  2. Hold down the ESC key while plugging it back in.
  3. Keep holding the ESC key for a few seconds until the keyboard resets.

Rule Out OS Key Mapping Issues

• On Windows:
  • Check if sticky keys or other accessibility features are turned on by mistake:
    1. Go to Settings > Accessibility > Keyboard.
    2. Disable Sticky Keys, Toggle Keys, or Filter Keys.
• On macOS:
  • Go to System Preferences > Accessibility > Keyboard and disable similar features.

Advanced Hardware Troubleshooting

• Inspect the PCB (printed circuit board): If you’re comfortable disassembling the keyboard, check for visible damage or dirt on the PCB that might cause key signals to overlap.
• Test with a key tester: Use an online keyboard tester (search "keyboard tester") to verify which keypresses are being registered.
• Firmware update: If your keyboard supports firmware updates, check the manufacturer's website for an updated version.

I hope this helps.

Take care and have a good day.
