About this tag
The main power tag covers discussions about performance differences when a laptop is plugged into mains power versus running on battery. A common issue reported is that games or applications run worse on main power, even though battery mode delivers better performance. This can be caused by Windows power plans, driver settings, or hardware configurations that inadvertently throttle performance when connected to AC power. Troubleshooting steps include checking power plan settings, updating drivers, and adjusting video card power modes. The tag is relevant for users experiencing stuttering, high CPU usage, or frame rate drops specifically when their laptop is on main power.
