It have standard US keyboard layout which is easy to use and type. it have in-build operating system in it of any type and hard disk capacity of 500 GB and beyond. It also have in-build Ubuntu operating system and processor of 2.0 GHz and core i3 for standard users and may be more for other users. However the hard disk space and processor differs to the type of users and the cost. It have got IPS screen and good battery life.This laptop have thick or rigid cover which is convenient for using and in case of falling. On top of that we will be provided with 1 year warranty of all parts of laptop unlike other. I have been using this type of laptop for 1 year and it is functioning well.
