ThinkPad E420s

There are basically no advantages. The appearance is OK.

It's too durable. It's been a long time. It's not worn out. The boss won't replace it

Excellent performance, absolutely lightweight. Just like the built-in battery bug, it can take up to 6 hours for word processing to surf the Internet and listen to music alone! The heat dissipation is good. It is above the average level. The air outlet has no temperature one day after starting up. After playing Warcraft for an hour, it doesn't feel hot. It's just a little warm. The performance is excellent after switching to unique display. The processor and graphics card have low frequency and stable performance.

The workmanship is poor. The display screen of my computer has a light leak. Although it is not serious, the screen is really poor. The workmanship is very rough. The silver edge at the rotating shaft of my screen is loose (fortunately, not a whole silver edge is loose --). Although it is said that this is an infinite fine steel screen, it is only made of fiber glass. It feels soft. But in terms of the fineness of color, it is still good. Master Lu measured it as the best display, and said that the screen display ability was insufficient to reflect

Young people who pay attention to practicality, stability, battery capacity, heat dissipation and performance, such as teachers, college students, management personnel and ordinary company employees, are very suitable for using this machine

It is thin and fashionable, only 1.88kg in ultralight. The i5 processor and 2G video memory are impeccable both in appearance and configuration. The configuration is mainstream and the cost performance is acceptable.

It subverts the traditional black design, weakening the business atmosphere and poor heat dissipation. Although the graphics card has 2GB independent video memory, the model of the graphics card is lower. Usb interface is few and near.

This machine is quite good and worth getting started.
