9 Topics0.011W Power Floor on i7-1255U: A Step Toward Microsoft’s Sustainability Vision
It is inspiring to see Microsoft leading the tech industry toward a greener future. Initiatives such as the Carbon Negative 2030 goal and the Energy Saver features in Windows 11 are important steps in environmental stewardship. These efforts show that software and hardware can work in harmony to preserve our planet. As a researcher, I have spent 18 months exploring how to further support this vision by identifying the absolute efficiency “floors” of the Intel Core i7-1255U (Alder Lake). My study focuses on a configuration that enhances Microsoft’s energy-saving protocols to achieve maximum hardware longevity. Key Technical Findings (18-Month Case Study): Dynamic Power Floors: Through precise optimization, I observed CPU power draw dropping to a floor of 0.011W at 1.8MHz during deep idle/sleep states, with the GPU reaching a 0W floor. Efficiency in Motion: During active productivity tasks, the system can reach 0.4W – 0.5W at a voltage range of 0.6V – 0.8V, demonstrating impressive scaling flexibility. Thermal Performance: The system consistently operates between 25°C – 35°C. In cooler ambient environments (15°C – 25°C), hardware can maintain 16°C – 20°C, virtually eliminating thermal stress. Battery Endurance: Using a standard 3-cell battery with 5% wear (originally marketed for 6 hours), these optimizations enabled up to 10 hours of continuous video playback. Uncompromised Stability: Over 18 months of daily usage, the system has encountered zero Blue Screen of Death (BSOD) events. This confirms that pushing efficiency boundaries can be done while maintaining the rock-solid reliability expected of the Windows platform. This study is a tribute to the versatility of Windows 11 and the engineering behind modern silicon. By maximizing the life of the devices we already own, we contribute directly to reducing global e-waste.

Hello I have a 2 day old new Sufrace 2 Laptop with Windows 10 Home and O365 subscription. Having switched from a MacBook recently I barely had time to set this up. But the Windows is up to date and I haven't changed any default settings. Yesterday was listening to a podcast on Chrome browser and paused it at 20 mins with 7 more mins to play. I left the browser open and use the laptop for few other things and closed the lid. In the middle of the night the Surface Laptop started playing the podcast automatically and closed the browser to exit. It was bit freakish TBH. My questions. 1. Why didn't laptop automatically go to sleep mode when I close the lid? 2. Why the laptop isn't in the battery saver mode with closed lid? I have already noticed the battery usage is high when just closing the lid. Should I select 'sleep' before closing the lid?695Views0likes1Comment
