That will depend on the compatibility and requirements of the APP. We recommend you check with the APP publisher's web site for their compatibility with Windows 10 S-Mode 64-bit operating system (Windows 10 S-Mode provides added security by only allowing APPs available ( and therefore certified by Microsoft) at the Microsoft Store. If you don't need the added security or you need to install APPs not available at the Microsoft Store, you can switch to standard Windows 10 Home 64-bit Operating System, at no additional cost.) and the minimum/recommended hardware requirements (Is a Graphics card required, the processor speed and the minimum required system RAM and the minimum available hard drive space) to run their program, then compare those requirements to this system's configuration

No, this model uses a dedicated, proprietary AC adapter/charger.
