Review Lenovo Essential B580 – Intel i5-3210M Wednesday, 24 October 2012

Lenovo Essential B580 – Intel i5-3210M comes with some design changes (compared with B570 series), i can’t say improvements because of new shiny surfaces. Intel changed the inner display plastic cover, now is glossy. New plastic strip added on upper edge, above keyboard and changed the speaker position and covers. The overall quality is almost as B570 series but the case now is not so clean and simple but still, remains mostly the same. When lid is closed, the laptop seems to be made from one piece. The surface is matte as for B570 series but some texture added with diagonal lines, seem more scratch resistant. As standard improvement for B580 series no matter what CPU and video is used, we get USB 3.0 ports, Intel wireless adaptor, Gigabit LAN adaptor, fingerprint sensor and 500 GB HDD unit. A better option for HDD unit will be 7200 rpm drive, at least for high end models, but unfortunately all are at 5400 rpm units.


In full load the i5-3210M reaches overall temperature of 83oc which is nothing special but the  surprise comes from cooler, only 35dB measured on the left side, close to cooler air grid. We have no clue what is the cooler rpm (seem there is no sensor) but what is certain is that this cooler is by far the most quiet seen in tested laptops so far. Intel CPU 3rd generation seem to be higher than 2nd generation but under 5%, anyway is better.


At start, in POST keys fuctions are:

  • F1 – access the BIOS interface
  • F12 – acces the BOOT menu


The cover that protects the LCD remain sturdy and solid, does not buckle at the current push in a normal situation. 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. The hinges are well anchored, allows display to be operated open / closed with minimal effort, same as B570 series.


Some changes can be noted on LEDs layout and number. The LEDs for HDD, Num Lock and Caps Lock are located in the right corner above the keyboard. Light intensity is good, not intensely annoying. The power supply and battery has now only one long LED, located on the edge. Because of length is easy to see even if it is positioned on the edge. All LEDs are green except for the power adapter and battery, that is amber when low power threshold is reached and is flashing red when the battery start to charged, after some time becomes green again. There is another LED near the power jack.


Battery lock is better than the one used in B570 series but is not perfect, there is no more gap but the battery is not is firmly anchored in place. Another oddity is the plastic wrap covering some sort of data ribbon in the space where the battery is installed, is not well glued so carefully !  do not try to remove it. Battery capacity is in the same range, only 4400mAh (48Wh) with 10.8v.


The Intel N Wireless Network Adapter average transfer rate is around 9.00 MBs/s. Maximum connection speed is 130 MB/s but only with default settings for [801.11n Channel Width for band 2.4] = 20 MHz Only, if you change to [auto], lets say for routers that have 20 / 40 MHz, will cut in half the maximum connection speed to 65MB/s.
