The new Asus laptop K53SJ SX249V-format 15.6-inch features an original appearance thanks to its blue color. It runs on Intel platform Huron River with a processor Core i3 Sandy Bridge, a great storage space and benefits from the technology associated with Optimus Nvidia DirectX 11.

Power4Gear technology automatically adjusts the fan speed to provide quieter operation while qu'IceCool maintains the wrist at a comfortable temperature. Palm Proof it ensures that the cursor will not activate the touchpad if ever the user accidentally touches the touch pad when typing.

It also has the distinction of integrating technology Nvidia Optimus who chose to run the laptop or on the dedicated graphics card Geforce GT 520M, on either the Intel GMA 3000 HD integrated processor Sandy Bridge. A shift is made between the two by Optimus automatically and in real time as needed. In fact, the Intel GMA 3000 HD is the most preferred to provide the best possible independence because it is low-energy. So, Optimus will use the Geforce GT 520M if it considers that the performance of the first insufficient to meet at some point the tasks performed by the user.

These two parts are graphs able to play HD video properly but Geforce GT 520M is more efficient. However, do not expect huge differences in this respect since it is an entry level GPU. As a result, only title-efficient can move, see the games a little more resource intensive 3D if one adjusts the levels of detail and resolution of the slab.
