The CPU performance limited status is Unhealthy

Symptoms

In the Microsoft Teams Rooms Pro Management portal, the CPU performance limited signal of a Microsoft Teams Rooms device is shown as Unhealthy, and the incident severity value is shown as Warning.

Note

Incidents that are classified as Warning don't affect the health status that's reported for a device.

Cause

This issue occurs if the following power setting on the Teams Rooms device is set to a value that's less than 100 percent:

Power Options > Advanced settings > Processor power management > Maximum processor state > Plugged in

Every Teams Rooms device includes a Windows configuration that specifies whether to limit the processor's maximum performance state. By default, this setting is set to 100%. This means that no limit is applied. However, the setting might sometimes be changed by your organization in one of the following ways:

• Through Group Policy Objects (GPO)
• Through Mobile Device Management (MDM) policies
• Manually by administrators

If this setting is set to a value that's less than 100 percent, it might affect overall processor performance during peak hours and also affect the ability of Teams Rooms to handle the full processing load. In this case, the Teams Rooms Pro agent detects and reports the status of CPU performance limited as Unhealthy.

Resolution

Microsoft Teams Rooms Pro performs an automatic remediation to fix this issue. However, if the issue persists or reoccurs, we recommend that you check whether any GPO or MDM policies are defined to change power plan settings. In these cases, use one of the following options:

• Use the Suppress ticket functionality to silence any notification about the CPU performance limited signal.
• If your organization uses GPO, MDM policies, or other management tools such as Configuration Manager for enterprise power plan management, make sure that the power setting isn't changed to a value that's less than 100 percent.

Additionally, use one of the following methods to set the value to 100 percent, depending on how the Teams Rooms device is configured.

Method 1: Use a Command Prompt window

Run the following command at a command prompt:

powercfg /SETACVALUEINDEX SCHEME_CURRENT 54533251-82be-4824-96c1-47b60b740d00 bc5038f7-23e0-4960-96da-33abaf5935ec 100

Method 2: Use the Control Panel

1. Select Start, enter edit power plan in the Search box, and then select Edit power plan from the results.
2. On the Change settings for the plan page, select Change advanced power settings.
3. Expand Processor power management > Maximum processor state.
4. Set the Plugged in setting to 100%, select Apply, and then select OK to save the change.

Method 3: Use Microsoft Intune to deploy a PowerShell script to devices

1. Save the following command as MPState.ps1:

   powercfg /SETACVALUEINDEX SCHEME_CURRENT 54533251-82be-4824-96c1-47b60b740d00 bc5038f7-23e0-4960-96da-33abaf5935ec 100
   

2. Create a script policy (add the script to script settings), and assign the policy to groups.
