HP Power Manager - The calling process is not signed by HP

[rayep]

Hi There,

I'm using HP Elitebook 840 G5 and recently got Dell Docking station, so thought enabling the power management option "Maximize Battery Health" through power control option in BIOS and HP Power manager.

Installed HP Power Manager  successfully, however, when opening it shows "The calling process is not signed by HP" with a Close button.

Version - 3.0.16.0.

Tried uninstalling/reinstalling multiple times, yet still same issue. 😞

Please help!

Your machine uses Dell's dock, now has some Dell's processes what are NOT from HP therefore it won't run.

@Banhien: Thank you so much for replying.

It's odd that the application actually opened one time and I saw all the battery options available such as Let HP choose, maximize, minimize usage, etc., and it suddenly started to show the error message.

I have tried by stopping the "Dell Peripheral manager service", still the same result. I'll try to uninstall the dell application and check the behavior.

Still the error message is odd, right? i.e., the calling process in my case should be something related to Windows like Windows Explorer as I'm just opening it from the Start Menu NOT through the any other 3rd party apps like Dell.

From process explorer, I can see svchost.exe is the parent process for the HP power manager which is "Background Tasks Infrastructure Service" of Windows.

Svchost.exe would be signed by Microsoft not by HP, so not sure how it worked one time.

Per this forum, https://learn.microsoft.com/en-us/answers/questions/1024474/problem-in-identifying-system-invoked-pr...

Which app's parent will be SVCHOST.exe?

SVCHOST.exe will be the parent for the Windows Store Apps like (calendar, photos).

That's what happening in my case too, so if that's the case HP power manager will not launch for anyone. Weird! 😞

Launch command - "C:\Program Files\WindowsApps\AD2F1837.HPPowerManager_3.0.16.0_x64__v10z8vjag6ke6\AD2F1837.HPPowerManager.exe" -ServerName:App.AppXq7s19m8tgk6hqrpr3vac5gqykj08k9jg.mca, so it's a store application.

I am also facing the same issue on my Elitebook x360 1030 G3 except that i haven't used any kinds of dock or anything the only thing that was done is updated via Microsoft Store to 3.0.18.0 so its weird to see this happen now
