Sometimes Developers may need to perform implementations based on Machine’s Battery and CPU power status. How to collect such information’s quickly ? Don’t know how to do. Don’t worry. MiTec’s System Information Management Suite’s component helps to retrieve such information faster. In this blog post we will learn how to use the TMiTec_APM component to collect power status of your machine with the sample application.
Platforms: Windows.
Installation Steps:
You can easily install this Component Suite from GetIt Package Manager. The steps are as follows.
- Navigate In RAD Studio IDE->Tools->GetIt Package Manager->select Components in Categories->Components->Trail -MiTec system Information Component Suite 14.3 and click Install Button.
- Read the license and Click Agree All. An Information dialog saying ‘Requires a restart of RAD studio at the end of the process. Do you want to proceed? click yes and continue.
- It will download the plugin and installs it. Once installed Click Restart now.
How to run the Demo app:
- Navigate to the System Information Management Suite trails setup, Demos folder which is installed during Get It installation e.g) C:UsersDocumentsEmbarcaderoStudio21.0CatalogRepositoryMiTeC-14.3DemosDelphi10
- Open the APM project in RAD studio 10.4.1 compile and Run the application.
- This Demo App shows how to access the system information like Battery and CPU Power Status.
Components used in MSIC APM Demo App:
- TMiTeC_APM: Component to retrieve Machines AC, Processor and Battery Power Status information’s by its properties such as ACPowerStatus, Battery by Battery Index, ProcessorPowerStatus by CPU index.
- TTabSheet1 shows the list of AC power status and the selected battery status properties and TTabSheet2 shows the Processor power status properties.
Implementation Details:
- An instance is created APM of TMiTeC_APM. Using APM properties Machine AC Power status, Battery related properties such as Manufacturers, Charge status, Battery Life, etc. were added to the TabSheet1 UI components.

- Using APM.ProcessorPowerStatus property provides information such as Max Frequency, Current Frequency, Frequency Limit, etc. for the selected CPU index and were added to the TabSheet2 UI components.
