I will appreciate vide sample There is no universal API for this. It depends on which OS you're using. For that, you need to consult your OS's documentation. Most likely there will be some kind of C API or system library that could give you this information. D can't possibly provide a universal API for something like this because it varies too widely -- some platforms do not have any meaningful notion of "battery level", whereas other systems may well have multiple "battery levels" and it would be ambiguous which one is meant. If you want to do systems programming you have to know the system you're programming, and be prepared to call OS APIs yourself.

SDL2 is a commonly used library though - you should be able to find more examples about it if you need to. Plus, the example I linked is not really the simple minimalistic one you want if battery level is all you want to figure out. Probably the derelict-sdl2 front page is what you're looking for that instead: https://code.dlang.org/packages/derelict-sdl2

As a systems language, D could access the hardware interface directly, if you knew it and loaded your program as a kernel driver - if your operating system lets you do that. Now, I don't think that was the most practical way to approach the problem :-). Instead, I recommend you use the SDL2 multimedia library to give you a more portable interface. Usage example in D here: https://github.com/Dgame/Dgame/blob/master/source/Dgame/System/Battery.d Note that the D module I linked does not contain the machinery to initialize SDL2. This module seems to contain that: https://github.com/Dgame/Dgame/blob/master/source/Dgame/Window/Window.d Note that DGame seems to be currently unmaintained - it might have some bits that do not compile anymore. SDL2 is a commonly used library though - you should be able to find more examples about it if you need to.
