Abstract: The present application relates to a computer implemented method, a computer program product and a computer system for controlling a data stream from a server computer to a client computer. The client computer comprises a data stream client and the server computer comprises a data stream server. While receiving, by the data stream client from the data stream server, the data stream, the method may comprise generating, by the client computer, a power management decrease event, receiving, by the data stream client, the power management decrease event, sending, from the data stream client to the data stream server, a first pause request to temporarily halt the data stream, and transitioning, by the client computer, from a fully working power state to a decreased power consumption state in response to the power management decrease event.
