I have the same problem with my Slate 21.

I have done the reset as per your instructions.

It is still the same - stays on the HP icon screen. Doesn't go any further.

@rajupagaria Welcome to HP Community!

I understand that stuck at the HP icon.

In that case, I would suggest you contact our phone support and check for the support option. They will help you.

If the product not under warranty there will be a charge for the support.

Here is how you can get in touch with phone support.

1)Click on this link - www.hp.com/contacthp/

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

We are experiencing longer than expected wait times to reach an agent due to the CoViD-19 impact and there might have been issues in you getting the expected resolution on the issue. 

Keep us posted,
