This error event happens regularly on a Windows 10 Dell XPS 15:
The description for Event ID 256 from source DPTF cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Intel(R) Dynamic Platform and Thermal Framework
ESIF(8.1.10600.147) TYPE: ERROR
DPTF Build Version: 8.1.10600.147
DPTF Build Date: May 26 2015 13:35:22
Source File: ..\..\..\Sources\Manager\EsifApplicationInterface.cpp @ line 737
Executing Function: DptfEvent
Message: Received unexpected event
Framework Event: DptfResume [3]
the message resource is present but the message is not found in the string/message table
Hopefully someone with access to the code can add a description for the error and fix it as well.
Thanks.
