Hi Gerry,

I would suggest you to try the steps below and check if this helps.

Step 1:

I suggest you to run the Power troubleshooter and check if it fixes the issue. Follow the steps given below:

You can run the Power troubleshooter to adjust your computer's power settings. The Power troubleshooter checks things like your computer's timeout settings, which determine how long the computer waits before turning off the monitor display or entering
sleep mode. Adjusting these settings can help you conserve power and extend your computer's battery life.

• Press Windows + X keys on the keyboard and select
  Control Panel
• Type Troubleshooting in the search bar on the
  Control Panel.
• Click on View all on the left navigation pane.
• Click on Power.
• Click on Advanced on the
  Power dialog box and click on Run as administrator (Enter the credentials if required).
• Click on Next and follow onscreen instruction complete the Power troubleshooter.

Step 2:

Try to restore the default power plan settings and check to isolate the issue.

• Press Windows + R keys on the keyboard to open Run command.
• Type powercfg.cpl to open the power settings.
• Click on Change plan settings beside your current plan.
• Click on Restore default setting for this plan and click on
  OK if prompted.

Let us know the status of the issue to assist you further.
