Turn off the computer and then restart it.
Press the Esc key repeatedly to see if a startup menu opens.
- If a setup menu does not open, the integrated keyboard hardware is not working. The integrated keyboard in the notebook should be serviced or replaced. To continue using the notebook, connect a USB-wired keyboard to a USB port and restart the computer. For further assistance, see HP Customer Support (in English).
- If a setup menu opens, use the arrow keys to navigate the menus. If these keys are working in the startup menu, but then fail when Windows loads, the problems are probably occurring in Windows.
To uninstall and reinstall the keyboard software in Device Manager, turn on the computer.
In Windows, search for and open Device Manager.
Click View and select Show Hidden Devices.

Wait for the computer to restart and open Windows.

The keyboard should now work correctly. To test the keyboard for key or hardware failures, see Testing for Hardware Failures (Windows 10, 8) (in English).

Key presses are slow to respond

If there is a short delay from the time a key is pressed to the time the character displays on the screen, the Filter Keys function might be activated. The Filter Keys function provides a greater range of key press options to fine-tune key delays and prevent inadvertent key presses. To disable Filter Keys and return to the default keyboard behavior, use the following steps:

In Windows, search for and select Change how your keyboard works.
At the Make the Keyboard easier to use screen, remove the selection from Turn on Filter Keys. Then click Set up Filter Keys.

On the Set up Filter Keys page, remove the selection from Turn on Filter Keys when SHIFT is pressed for 8 seconds to disable the Filter Keys keyboard shortcut.

Click OK, then close the Ease of Access Center.

The keys should now be more responsive.

If two or more characters appear when pressing a key, use the following steps to adjust the key repeat delay:

From Windows, search for open Keyboard.
On the Keyboard Properties screen, drag the Repeat delay slider to Long, and then click OK to save changes.

In Windows, search for and open Change how your keyboard works.

In Windows, search for and open Control Panel.
In the Control Panel search box, type keyboard layout.
Under Language, click Change input methods.

Figure : Change input methods
Next to your primary language, click Options.

Switch keyboard layouts by pressing the Windows + spacebar keys.

The current selected language and keyboard layout are displayed in the Settings screen, in the taskbar on the Windows desktop, and in the bottom right corner of the sign-in screen when you sign in to Windows.

Stuck notebook key

If a key is physically stuck in the down position, you might not have to replace the entire keyboard. Many keyboards have keys that can be removed by inserting a butter knife under one edge of the key and gently prying up on the top and bottom edge. After the key has been removed, using a swab with alcohol, clean the underside of the key and the key's slot in the keyboard. Replace the key by snapping it back into place.

caution:

If the notebook is still under warranty and a key is stuck, you should contact HP to see if the notebook can be serviced before removing a key.

caution:

To avoid damaging the pad under the key, insert the butter knife only 1/8 inch under the edge of the key.

Other tips to think about when encountering a stuck key:

Turn off the notebook and unplug the AC adapter before working on the keyboard.
If your notebook has a removable battery, remove the battery before removing the key.
If the key is stuck due to liquid or other substance getting into the keyboard, cleaning might be the only option.
Longer keys, such as spacebar and Enter, probably have a small metal rod for support. This rod must be inserted into the key and keyboard before replacing the key into the keyboard.

If a key cannot be unstuck, or the keyboard does not have keys that can be removed, service the computer.
