X1 Carbon Yoga Some Hotkeys Stopped Working - AGAIN

[MattCCRE]

Members,

Looks like the hotkey problem is back with Windows 10 Pro 1909...

From my last run-in with this problem: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-Yoga-Some-Hotkeys-Stopped-Working/m...

I rolled back to 9.1.0.2 as per this page with no luck either.

Specs: 

Product: 20FQ001VUS

BIOS: N1FET70W (1.44)

Windows 10 Pro 64-bit Version 1909 Build 18363.476

Hotkey Features Integration for Windows 10 (64-bit) - ThinkPad Version 9.1.0.3 or 9.1.0.2

All updates completed (Lenovo and Windows).

Thoughts?

Open services.msc and check to see if following services are installed AND running:

- Lenovo Hotkey Client Loader

- Lenovo PM Service

- Windows Management Instrumentation

- Windows Audio

someotherguy,

Here are my results:

- Lenovo Hotkey Client Loader - running (auto)

- Lenovo PM Service - disabled(!)

- Windows Management Instrumentation - running (auto)

- Windows Audio - running (auto)

After re-enabling Lenovo PM Service, starting (set to auto) and rebooting, everything started working again!

Not sure how/why Lenovo PM Service got disabled...

Thank you AGAIN for your quick support!

Much appreciated!
