Abstract: Particular embodiments described herein provide for an electronic device that includes a battery, a display, an embedded controller to determine a battery condition and set an indicator when then battery condition is at a low power state, and a basic input/output system (BIOS), where, before an operating system stage of a boot process, the BIOS sets a brightness of the display at a native brightness if the indicator is not set and sets the brightness of the display at a low power brightness to reduce the brightness of the display if the indicator is set. In an example, the embedded controller sets the indicator before the central processing unit is reset during the boot process.
