Bonjour @andre.hub ,

Bienvenue au sein de la communauté Norton d’entraide entre utilisateurs.

Avec les éléments que vous donnez, il n’est pas possible d’exclure cette hypothèse. Néanmoins, vous avez de nombreuses autres causes possibles et plus probables de ce disfonctionnement.

Cordialement

Guillaume

@andre.hub If you could give us the maker and model of your laptop, we’d be glad to have a look at the hardware involved. Do some research and see if this issue is a common one for that manufacturer and/or hardware.

Some specific questions come to mind:

  • Are you using Norton Utilities, Driver Updater or Software Update by chance?
    -What version and build of Windows are you using?
    -What is your installed version of Norton?

Here are some AI suggestions you may try:

AI Overview

When both your numeric keypad and sound stop working suddenly on a laptop, it usually points to a system crash, an issue with Windows updates, or corrupted hardware drivers. [1, 2]

Follow these steps, in order, to fix both issues:

  1. Perform a Hard Reset

This drains residual power from the motherboard, clearing out temporary glitches that can freeze hardware controllers. [1, 2]

  1. Turn off your laptop completely.

  2. Unplug the power charger and remove any connected USB drives or headphones.

  3. Press and hold the Power button for 60 seconds.

  4. Plug the charger back in and turn on the laptop. [1]

  5. Update or Reinstall the Keyboard Drivers

If your number keys are typing nothing, or acting as a mouse, the keyboard’s driver may need to be reset. [1, 2]

  1. Right-click the Windows Start button and open Device Manager.

  2. Expand the Keyboards section.

  3. Right-click your keyboard (often listed as HID Keyboard Device) and select Uninstall device.

  4. Restart your laptop. Windows will automatically reinstall a fresh, working driver upon reboot. [1, 2, 3, 4]

  5. Check “Mouse Keys”

Sometimes, the Num Lock key accidentally activates Windows “Mouse Keys,” turning your numeric keypad into a mouse pointer instead of a typing pad.

  1. Go to Settings > Accessibility > Mouse.

  2. Make sure the toggle for Mouse Keys is turned Off. [1]

  3. Reinstall Audio Drivers

If your speaker icon is grayed out or has an “X” next to it, the sound card driver is likely glitched. [1]

  1. Go back to Device Manager.
  2. Expand Audio inputs and outputs.
  3. Right-click your speakers/headphones and select Uninstall device.
  4. Expand Sound, video and game controllers and uninstall any audio devices listed there as well.
  5. Restart your laptop so Windows can reinstall the sound software. [1, 2, 3]
