ThinkPad T420s

1. Fine workmanship, durable construction; 2. Top endurance; 3. Dual graphics card switching; 4. The last generation of classic splash proof keyboard; 5. Special is thinner, lighter and easier to carry, and its performance is unchanged compared with 420; 6. Hardware configuration pursues running speed and compatibility, and running 64 bit system is relatively stable; There is no need to say more about classics

1. The number of U ports is too small, and the location is awkward. There is no common U port on the right for mouse use; 2. The speaker quality is too poor, which should be the only weakness of this generation of Xiaohei; 3. Standard memory cutout; 4. The legendary business acme is more perfect if there is a built-in wireless Internet device (not WIFI), although this is not a defect rather than a defect; 5. Also the most important: the price is too expensive

I have been following this model for many years, and recently (2015) a rich student finally had the opportunity to borrow it for a day or two after buying it... As a fake little black powder, I feel familiar and strange at first, but I can't put it down... After using it, I have comments on its advantages and disadvantages, and I will not repeat them here... In a word, I am reluctant to return it, so I can save money to buy it

1. The workmanship is excellent. Although it was given to Lenovo, the excellent workmanship and combination of the T series are still not short; 2. Keep the original TP design patent with feelings; 3. The i7 second generation high configuration CPU runs programs that are super fast and stable. Programmers pursue it, and I personally suggest SSD; 4. Light weight, easy to carry; 5. The last anti splash classic old keyboard has a good feel; 6. There is centralized display, and it is also equipped with independent display, and the independent display is a professional NVD graphics card, which is more attractive for graphic designers;

1. The heat dissipation is extremely poor. Although it is an independent video card, it also brings amazing heat. It can basically fry eggs without a pad... 2. There is no USB interface on the right side. If you want to plug in a mouse, either you have to buy a wireless interface, or use the rear electric yellow mouth directly, or you can turn yourself into a left-handed person; 3. The number of sockets is small, and this book has forced me to use PCI expansion slots; 4. The average endurance may also be due to my unique high configuration; 5. BGA packaging is completely different from the motherboard design of the T420 ordinary model. It is basically impossible for non professional players to upgrade their hardware;

Originally, the T420 is a classic, but the S model is still of good workmanship and rarity. The black powder can be bought and displayed, and the T series of exotic products can also be collected
