Power Tuning Linux: A Case Study

on YouTube ↗34m

" summary

Measurements use a Yokogawa WT310 power meter and a photometer plus PowerTOP for tuning on a Sony Vaio Core i5 SSD laptop with 20 minute runs. Default settings show the LCD panel uses about 80% panel of idle power; simply running PowerTOP saves ~5% while upgrading to a recent upstream kernel and then running PowerTOP saves ~20% without dimming. Changing backlight and screen color (solid black vs white) yields multi‑watt differences; a USB mouse appears unusually costly.
