@Dickhata, Welcome to HP Support Community. 
 
Thank you for posting your query, I will be glad to help you. 

I'm sorry to hear that your new HP Pavilion 15t-cs200 laptop keyboard isn't working. Let's go through a few steps to help resolve this issue.

Perform a Hard Reset

Sometimes, a simple reset can fix hardware detection issues.

1. Power off the laptop.
2. Disconnect the power adapter and any external devices.
3. Press and hold the Power button for about 15 seconds.
4. Reconnect the power adapter and turn the laptop back on.

Check if the keyboard responds.

Test the Keyboard in BIOS

This helps determine if the issue is hardware or software related.

1. Turn off the laptop.
2. Turn it back on and immediately press the Esc key repeatedly (once every second) until the Startup Menu appears.
3. Press F10 to enter BIOS.

If the keyboard works in BIOS, it's likely a software/driver issue. If it doesn't, it may be a hardware problem.

Update or Reinstall Keyboard Drivers

1. Right-click the Start button and select Device Manager.
2. Expand Keyboards.
3. Right-click on the keyboard device and select Uninstall device.
4. Restart your laptop — Windows will reinstall the driver automatically.

You can also check for driver updates via HP Support Assistant or manually from the HP Software and Driver Downloads page.

Run HP Hardware Diagnostics

HP provides a built-in tool to test hardware components:

1. Turn off the laptop.
2. Turn it on and immediately press Esc, then F2 to open HP PC Hardware Diagnostics.
3. Select Component Tests > Keyboard Test and follow the prompts.

 I hope this helps. 
 
Take care and have a good day.
