Windows Server 2019 Task Manager CPU updates not working HP or HPE Proliant Servers

For some strange reason, after installing Windows Server 2019 on HP/HPE Proliant Servers, the CPU graph realtime update will stop working. The graph does not update any CPU usage in the graph chart.

After some researching and doing some testing on my own, this issue seems to affect the older Proliant Servers. After testing it on ML310E Gen8, DL380 G7, DL380 Gen8 and DL380 Gen9, it seems like only DL380 Gen10 does not have this problem.

The work around to solve this issue as provided on some forum is to change the BIOS “Power Regulator Settings” to “OS Control Mode”. The setting can be accessed from the ILO settings.

Here’s the various ILO examples:

ILO 2:

ILO 3:

ILO 4:

Here’s an example of Before and After the changing of the settings:

After:

That’s it.

Hope this helps.
