Lenovo Y40-80-IFI (H)

The laptop I got at the end of July was 5350 yuan in a third tier city. I used to use Lenovo's z465 laptop. The Y40-70 fan is excellent in heat. After using it for more than 20 days, I never felt the body was hot, and it was cool in summer; High definition screen, the characters are a little small, and the eyes hurt. The sound is a little low, but the sound quality is very good; The fuselage is very thin and strong, which is domineering from the side. The combination of black and saucy gives a feeling of arrogance and side leakage. The endurance is very good. After filling, you can watch the video for more than 7 hours!

The Lenovo logo on the back is not glued a little, and it will rise a little inadvertently. The 5400 rpm hard disk is a bit stuck. SSD+mechanical hard disk is not supported. You can only choose one from the other. Go back to school to get a scholarship and change to ssd.

The combination of black and saucy gives a feeling of arrogance and side leakage.

On the appearance, Y40 has a striking feature, and extends the style from color matching to appearance, similar to the high-end Y50 model, like a miniature version, which is convenient to carry out. The audio is customized with JBL, and the sound quality is very good. The AD surface imitates the carbon fiber pattern, giving consideration to the hand feel and eye-catching. With the I5-4210U+R9 independence card, the roast chicken has reached the limit that the machine can run at the highest performance without frequency reduction. In addition, it is also the only machine with light and thin, 14 inch, 1080P, middle end graphics card and drafty appearance within 5000. Performance is about 2/3 of that of GTX850M, better than that of GT750m/GT840m. Although the dual fan system is used, the noise is very low and the temperature can be controlled at a very low level during normal use. Due to the use of the built-in lithium polymer battery, the wrist rest is cooler and has guaranteed endurance

Although the dual fan system is used, the temperature is still high due to the common material of heat pipe. If you play large games, the CPU and graphics card are under relatively high operating loads, the temperature will rise further. In addition, the position of the heat sink also affects the heat dissipation efficiency. No interface with built-in SSD, such as NGFF and msata

Y40 may be the only machine available at this price. Don't obsess about low-power processors. It is the absolute principle to be easy to use and enough to use

I like the design, the memory is large enough, and the keyboard feels good

The battery really wears out fast! I don't play games and seldom use my computer to watch videos. I just use it to do some ppts and edit documents. As a result, the battery is almost unusable after more than a year. First, the power display is abnormal, and then I turn off the power directly from 70% of the power displayed. I can't use it without plugging in the charging cable. I am also very helpless. I can't bear to change the battery, It turned out that every time I opened some software, there was a sound of "card". I asked the maintenance personnel about the normal phenomenon, and said that if I didn't trust myself, I would go to see it again, but I really didn't want to carry the computer all the way!
