Screen went black after update

[Mshelld]

I just purchased this notebook two weeks ago and last night I was prompted to complete an update before the computer with power off. This morning when I went to turn the computer on it said that it was completing a BIOS update. It said that it would take a little time and then it prompted me to sign in with my Microsoft password and then reset my PIN number. After that the screen has been black ever cents and all I can do is see the mouse moving around? Any help would be greatly appreciated as I have conference calls and teletherapy calls to complete with my speech students during the midst of this pandemic.

Welcome to HP Community

I have gone through your Post and would like to help

Please try a System Restore to an earlier time before the issue started

- Shut down the computer completely.
- Turn on the computer and repeatedly press the F11 key, about once every second, until you see the Windows loading screen.
- If a language selection screen opens, select the language you want to use to continue.
- On the Choose your keyboard layout screen, select the keyboard layout that matches your keyboard type.
- On the Choose an option screen, click Troubleshoot.
- On the Troubleshoot screen, click Advanced Options.
- On the Advanced options screen, click System Restore.
- Click Windows 7 as the target operating system.
- The System Restore window opens. Click Next.
- Click the restore point that you want to use, and then click Next.
- The Confirm Restore Point window opens.
-Click Finish to restore your computer to a previous point.
- Do not interrupt System Restore when it starts. Doing so can corrupt your hard drive and create more problems. Click Yes in the warning that appears.
- System Restore returns the computer configuration to a previous point in time and restarts.
 

If you are unable to access the Restore point, please perform a Reset. You can refer to this Link: https://support.hp.com/in-en/document/c04742289
