Lenovo Z580

Good appearance, good heat dissipation, low fan sound, convenient five shortcut keys under the screen, and good keyboard feel

May Day was very comfortable when I first bought it, but now I start the software "very slowly, very slowly". I don't know why. Power on and power off are also very slow. First of all, I have few software installed. The key point is that the software starts slowly, sometimes the web page opens very slowly [not the problem of the network speed], sometimes I wonder if there is something wrong with the memory module, only five months ago! Also, the screen brightness is too bright. I don't feel it during the day, but I can see it at night. I can't adjust it yet.

Generally speaking, it is a good notebook, except that the software will start slowly after a period of time!

Overall, it's OK. The office and games are all pretty good now, but I upgraded the configuration, added a memory module, and replaced a solid state disk. Now I can watch TV for 1.5 hours when fully charged. It used to be 4 hours. The only drawback is that it is heavy and thick, but it also has good heat dissipation Cost performance, endurance, screen effect, heat dissipation effect, appearance design, running speed,
