1. An electronic device comprising:
a first display;
a second display; and
a basic input/output system (BIOS), wherein during a boot process for the electronic device, before a premem stage and memory reference code (MRC) initialization, the BIOS communicates a signal to power enable the first display and the second display.
 
8. A method comprising:
determining that an electronic device is powered on;
starting a boot process for the electronic device;
using a basic input/output system (BIOS), power enabling a predetermined number of displays before a premem state and memory reference code (MRC) initialization of the boot process;
determining if each display from the predetermined number of displays is active; and
closing a power path to any displays that are not active.
 
15. A system for enabling a similar boot time for multiple displays in an electronic device, the system comprising:
a power supply; and
a basic input/output system (BIOS), wherein on startup of the electronic device, during a boot process, the BIOS causes power from the power supply to be enabled to each of the multiple displays on a separate power path.
