Rapid Boot Extreme is an optimized Lenovo Preload designed to allow a T420s to boot up in just a few seconds. This includes changes to BIOS, and optimizations to the regular software preload to allow for a fast boot up. The Rapid Boot extreme feature can allow the ThinkPad T420s to boot in seconds, but delays the startup of some applications, drivers and features.
