Advantages: 1. Moderate weight, meticulous workmanship, reflecting the consistent characteristics of thinkpad in details.
2. The system is stable and reliable, with minimal sound and outstanding heat dissipation performance. It is generally used between 40-50 degrees (the ambient temperature is below 25 degrees). When the ambient temperature is around 30 degrees, it is generally used Between 50-60 degrees, temperature and stress test, continuous high-intensity independent graphics (6630M) operation for 15 minutes, the temperature is around 75 degrees.
3. The quality of the optical drive and screen is very high, which belongs to the premium level. It is much higher definition than some notebooks, but certainly not as good as the X220, a top-notch notebook. The acoustics are also good.
4. The hard disk (320G@7200, Western Digital black disk) is of high quality, except for the smaller capacity.
Disadvantages: 1. The initial 2G memory is not large enough, and the system occupancy rate can reach 70% or more, so additional memory is required;
2. The back cover is not easy to disassemble and is very tight. ; The fan is located very far inside, and you need to disassemble the whole thing to see the fan, which is very disadvantageous for dust removal from the fan in the future (I have used notebooks for 10 years, and I have experienced that the ease of dust removal is really different between different notebooks).
3. The 4-cell lithium battery (marked 25) is very weak. It can last for one and a half hours under normal use.If you are a long-term mobile office worker, I recommend the X220. And the battery box is very loose.
4. The price of after-sales service is relatively high
E420 review
Appearance introduction
Since there is nothing mysterious about unboxing, let’s get straight to the point and take a look at the appearance! Although the ThinkPad Edge subverts Xiaohei’s traditional design style in terms of appearance, its unique design and color scheme have also attracted many young business users. I learned from the dealer that the red-colored E420 is also favored by female users.
Complete machine performance test
First of all, the author installed the 64-bit Windows 7 Chinese Ultimate operating system on the ThinkPad E420 (1141-A35) for personal use (since it is a personal notebook, so There is no English version of the operating system installed, but the data tested in this way should not be very inaccurate). The driver problem is easy to solve. It can be packaged and downloaded from Lenovo’s official website, and supports one-click fool-proof installation.
Processor
The ThinkPad E420 (1141-A35) that the author purchased is equipped with the i3-2330M, the entry-level product in Intel’s second-generation Intelligent Core processor family. In terms of processor performance, there is a slight improvement compared to the previous generation i3-2310M. The main frequency has been increased from 2.1GHz to 2.2GHz. The dual-core four-thread and 3M L3 remain unchanged and does not support Turbo Frequency technology.
Graphics card
ThinkPad E420 (1141-A35) adopts a built-in core graphics card and AMD Radeon HD6630M dual graphics card switching design. Users can Switch graphics cards based on usage needs for optimal performance or longer battery life.
Memory
As we all know, whether it is playing games or multitasking, 2GB of memory is already a bit tight. Upgrading itUpgrading to 4GB of memory is already a general trend. Therefore, the author upgraded his own ThinkPad E420 (1141-A35) to 4GB of memory.
The above is the introduction of the parameters of thinkpad e420. Now everyone knows something about this notebook! The market price of this notebook is about 5,200 yuan. It is a relatively reasonable price, neither high nor low. Combined with its parameters, it can be seen that this is a relatively cost-effective laptop. Thinkpad is actually a laptop brand under the IBM PC Division, so I personally think this is a laptop worth considering.
