Change your Power Plan
By default, Windows chooses “Balanced” as the recommended Power Plan on a new Windows Server deployment. It’s an option you should change and one that’s most often overlooked in my experience. Production SQL servers usually aren’t being powered by mobile laptops with batteries, so we’ll need to use an option that gives SQL more breathing room. The goal is to make sure the server is always on-the-ready and not sacrificing processes or services for the sake of fairly minimal reduction in power consumption.
Instead of “Balanced”, choose the “High Performance” mode. Your SQL Server will thank you. This is easily done by going to the Control Panel, clicking on “Power Options” and picking the power plan more optimized to run SQL Server. Those that are savvy could easily update the changes to all their SQL servers at once by using a Group Policy.
