It sounds like the password reset may have completed successfully, but the laptop could still be expecting a different sign-in method or account than the one that was updated. Since you've already reset the Microsoft account password and the PIN reset option isn't working, it would help to narrow down how the device is configured before trying more recovery steps.
Could you confirm the following:
- On the sign-in screen, do you see an email address (Microsoft account) or only a username?
- Is the laptop connected to the internet from the sign-in screen (Wi-Fi or Ethernet)?
- When you enter the newly reset password, do you receive an error message? If so, what is the exact wording?
- Are there any other sign-in options available besides the PIN prompt?
These details can help determine whether the device is using a Microsoft account, a local account, or if the sign-in credentials have not yet synchronized after the password change.
