Lenovo Y470

1. The voice of dual speakers is bright. When I installed Win7 (I don't know which version) and 360, the right horn stopped working, and I thought it was broken. Later, the win8 professional version was installed. The right speaker was inexplicably good, but not all good. It sounded when the volume exceeded 50; 2. Chocolate keyboard with a thin keyboard film makes typing feel good; 3. Sleeping at night and falling down for three times, it can still be used normally, and it is tough.

1. The dual graphics card has no real name and is very uncomfortable to use. People who do not understand the graphics card should not adjust the image and graphics values in the graphics card at will, which is easy to make the computer can not play anything. 2. The fever is serious, and you can bake yourself on your legs in summer. 3. The management plug-in of the touch control board is very annoying. I went to Lenovo's official website to download a new version of the plug-in, but it can't be started automatically. As a result, the touch control board has not been used since I bought it. 4. The details of the fitting part are generally processed. It is located in the northwest with many sandstorms. The computer often gets dusty, Both sides of BC are dust leaking from rough cracks. 5. It looks too ugly, so I had to go to a treasure to buy a dazzle film, which is slightly better.

It's OK. I won't lose or make a profit.

I bought it for two years and didn't use it very much. I always keep it at home and sometimes take it out to kill viruses. I don't think it's any different. It's just that the two speakers have better sound quality than those of ordinary laptops...

It has been at home for some time. When I take it out again in winter, since the heat expands and the cold shrinks under the control panel, it will spring up when I press it down. Is it a quality problem or a quality problem?

It should not be said that I am unlucky or Lenovo is poor in quality...
