ThinkPad E590

The appearance, keyboard, weight and workmanship are generally good, maintaining the style of thinkpad. Although the keyboard is not as good as other series of tp products, it is also better than other brands of similar notebooks horizontally.

Video card! Let's emphasize the graphics card again! As you know, this E590 is equipped with independent graphics card and dual core graphics card. Under normal conditions, the single display hardly works. The 2G video memory is useless, and no official standard method for switching video cards has been found. After disabling the core display and forcing the use of the independent display, the independent display finally starts to work, and the video memory also starts to be used. But with the support of the independent display only, even the built-in Windows system will drop frames. The online search showed that E580, a product of the same series with the same graphics card, is almost identical to E590. Many people reported that they would get 20 frames of cards when playing lol (E590 has just appeared, please use Baidu E580 LOL). Obviously, either the independent display is not enabled, or the independent display is enabled, but the independent display is inferior to the core display. (I also saw the statement that it would be better to play lol with E580 and disable the exclusive effect, which is a bit confusing) After consulting Thinkpad online customer service, they said that the graphics card would automatically switch as required, and disabling the core display would lead to abnormal display (this explanation said that it was difficult for me to accept the frame drop of Windows, just like I didn't say, it didn't tell me how to normally not drop the frame when I switched to the single display, let alone how to only switch to the single display) According to various signs and personal tests, the E590 Uniquely Display does not seem to have any existence value, because when you use Uniquely Display, its performance is not even as good as that of Core Display. Of course, the rx550 video card, the author does not believe that its performance is not even as good as the core display. There must be something wrong with it, which limits its use. But when I asked online customer service, I didn't get any answer. The answer was to tell you that this frame drop is a "normal phenomenon". The notebook automatically switches to the video card, and the display will work when needed. Even when the author mentioned the common sense that the video card display will occupy memory space when there is no video memory, the customer service also began to send the definition of memory and video memory to the author, As for the author, he doesn't understand video memory, which confuses the public. If the graphics card of about 600 yuan can only play to this state, it seems dispensable. This really made me feel cheated. More than 7000 laptops have lol20 frames. I don't know it's too much.

Looking at Duxian, who was hardly used, shed tears of regret. It is also expected that the official can upgrade a bios to solve this problem.

The screen is very large

The battery has not changed
