Introduction

The ASUS UM5606 (Zenbook S 16, 灵耀16 Air) laptop offers good experience when running Linux, especially ArchLinux. However the laptop's battery life has long been plagued by an issue that the APU's memory clock (MCLK) does not downscale even at light load or idle. The root cause of the issue is regarding the internal OLED panel's tight vertical blanking (vblank) timing and now has been solved. Please refer to the archwiki entry for details.
