With this regard, they incorporated a system such that you can tweak you PC’s power plan to suit your individual needs. If you want it to save power then you can use the power saver profile, if its performance you want then you can use the high performance profile. But if you are after both the performance and guaranteeing a longer battery life, then they included a balanced profile. You are not only restricted to this plans, they made sure that you are able to create a customized power plan.
