Review Lenovo Essential G570 – Intel i5-2430M Friday, 17 August 2012

Lenovo Essential G570 is big brother of B570e notebook. Materials quality wants to be better but i can’t agree with that.  The case has clean and simple design, same as for the cheaper B570e only that everything shines and is not necessary a good thing. Unfotunately with lid closed, you can see that the line doesn’t give “one piece form” impression, thats because of round edges. The surface is shiny and, of course, this means that is very sensitive to scratches and dust. I can safely say that if i need to choose from design and ergonomy point of view, i’ll go without thinking twice for little brother, B570e.


An nice feature is the cover that protects the LCD is sturdy and solid, does not buckle at the current push in a normal situation but is shiny and and verry hard to mantain clean. The same applies for the plastic band that covers the screen edges, very well placed, with no gaps between LCD and the plastic edge band but again shinny and no scratch resitance. Anyway the rubber bands attached to the edges that keeps the LCD screen from pushing into keyboard are thick enough to safely asume that will never touch the keyboard. The hinges are well anchored, allows display to be operated open / closed with minimal effort but are not that sturdy as those mounted on B570e.


The LEDs for Num Lock and Caps Lock are located perfectly, in the left corner above the keyboard. Light intensity is good, not intensely annoying. The LEDs for HDD, power supply, battery and screen are located on the edge, uncomfortable to see if your laptop is not up but this is not a problem because LEDs are not of current interest to the user except for HDD LED which was placed uninspired. All LEDs are white except for the power adapter and battery, that are flashing red when the battery is charged.


Battery lock system is robust, despite the fact that is the same mechanism as for B570e the switches are solid and hold steady the battery in place, no gap movement. The battery capacity is odd choice, considering that B570e has a 4400 mAh battery, and the G570 is more powerful, with a better processor but also power demanding and most important of all with a dedicated video card that is a major consumer when is used. Despite that the G570 has a smaller battery capacity – 4050 mAh. Voltage is almost the same, while 10.8 v G570in B570e has 11.1v.


For an mobile N Wireless Network Adapter the maximum transfer rate is 9.36 MB/s with maximum connection speed at 150MB/s, doesn’t matter power saving mode set, CAM (Constantly Awake Mode) or Max-PSP (maximum Power Saving). So we have high transfer rate for an notebook. Average transfer rate is around 6.00 MB/s moving allover the places, with more or less walls between notebook and wireless router.
