The Lenovo Z510 is a well built laptop with a matte-coloured finish on the top flap and a metal-brush finish on the palm rest area. At 2.2kg it is certainly heavy and not ideal to carry around.
Opening the laptop is relatively slower thanks to the big screen and a sturdy hinge, which allows the screen to open up to 120 degrees. On the under side of the laptop, you have four large rubber feet which help get the laptop get a good grip on a flat surface. Considering the size of this laptop, using it on your lap while working will get uncomfortable after some time.
It boasts of a full-sized keyboard with scalloped keys. The keyboard is backlit and you can adjust the brightness of the backlight. There is a complete number pad on the right hand side. The keys are well built and have a decent amount of travel. For someone moving from a non-number pad keyboard to this, the layout will take some time getting used to. The mouse trackpad is placed in the left of centre and is a monolithic design. We are not fans of monolithic designs on trackpads and in terms of usability, this one disappoints as well. You are much better off using a dedicated mouse.
