The long battery life was realized by using Toshiba's own BIOS to control the hardware. The notebook PC, "dynabook KIRA V634/27K," is one of the five series (ten models) that the company will release Nov 22, 2013.

All the models in the dynabook KIRA series of notebook PCs have a battery life longer than about 14 hours because they come with "the fourth-generation Intel Core i5 Processor," which features a low power consumption, as well as a low-power-consumption LCD backlight source. In addition, devices in the PCs are meticulously controlled with Toshiba's own BIOS.

Among them, the dynabook KIRA V634/27K, whose battery runs for about 22 hours, is equipped with a 13.3-inch HD wide LCD panel whose pixel count is 1,366 x 768. Its low weight (1.12kg) was realized by reducing the sizes of printed circuit boards (PCBs), changing the locations of antennas and utilizing various forming techniques.

For its body, Toshiba used a magnesium alloy, which has a light weight and high strength. Also, the company applied a special magnesium stamping technique to its top plate for realizing both a high strength and excellent texture in the aim of showing high-grade fineness.

The dynabook KIRA series has a 4k-compatible HDMI output port and can output high-resolution images and movies to a 4k TV. Toshiba adjusted the colors of liquid crystals for each panel in accordance with of its individual difference so that it can display natural colors.
