Lenovo Y400 Y400N-IFI (Linux)

CPU: 22nm technology, low power consumption and little heat release. Although the 750 graphics card is not very good, it is good to play general online games. LED backlit keyboard, good hand feel, back is also very powerful.

The camera is really too blurry. It's better to cancel this thing. The battery runs continuously. After three hours, it almost ran out of power. I felt it was a little unsatisfactory.

On the whole, it's pretty good. I always think the price is a little high, but people who buy for others agree with the price. The warranty for this product is only 2 years, which is really a bit unreasonable. I hope that Chinese products will be better and better.

Power on and power off quickly Good heat dissipation After sales was OK

Occasionally, the machine is jammed, especially when it is superimposed on more than 10 windows No frequent wifi disconnection

Y400 (T) On the first day of use, the left button of the touch failed. Clicking on the lower left corner of the touch did not respond at all. After five hours of continuous use, the whole touch failed, and the zoom function failed. The page was superimposed on seven pages, and the machine crashed. We rushed to the Suning Appliance we bought, and explained the situation to the sales person. After the startup inspection and description of the problem were correct, we suggested that I take the box to replace it or refund it the next day. The next day, I thought twice about whether to refund. Finally, I replaced a brand new machine. I checked with Master Lu, and found that the CD-ROM drive has changed from Panasonic to Hitachi. Anyway, it doesn't matter where it is not commonly used. The sales were easy to talk about. I extended the return and replacement time for seven days, and gave away the screen film. Now it has been used for more than a month, and the boot speed is still amazing, It didn't take more than 20 seconds. The same thing happened when I shut down the phone. Occasionally, when I took it out of the office, the speed of turning on and off the phone caused onlookers to look around. Occasionally, the game played cool. I like to stack windows on my computer. Occasionally, it will stack up to 40+. The new phone hasn't been jammed yet. The previous WiFi is often offline, but it hasn't been replaced. In short, the performance is good. Tips: When a new machine arrives, it must be operated for a long time. The quality of each batch of goods is different. We must cherish the seven day package return time and the fifteen day package return time

Play the game smoothly without getting stuck

I want to ask, what is the meaning of the blue screen when you click cf and pull out the mouse? And the touchpad is blue even if you slide it. Everything else is OK...
