A certain/the new brand of/my laptop computer.
It is black, but has some details in gray and it´s fairly heavy, yet lighter than a desktop computer.
It is bigger than a standard laptop computer, however smaller enough to be carried in a backpack, you wishing.
*A welcome feature of the keyboard is that its keys shine when pressed wich it´s very good when one needs to use the laptop in the the dark. Finally, its screen is large and clear/and have a high resolution. Thus, it is perfect to work.
*Its backlit keys with iluminated letters/characters are a feature that comes in handy when one needs to work at some dark room/to use the laptop in the dark.
By talking about a laptop computer viz-a-viz a "standard laptop computer" may leave the reader confused a little bit, that´s why I have redone the title.
