What about the Lenovo Y400? Can I play CF? What about heat dissipation?

Dear Lenovo users, hello!

Thank you for your attention to Lenovo's products, if you are interested in purchasing, if you want to understand the functional characteristics of the machine, in order to better choose the machine that is suitable for you, it is recommended that you contact the pre-sales service consultation. Lenovo has dedicated pre-sales engineers to provide you with free professional specific analysis and advice based on your individual needs.

Convenient for your choice, you can also go to your nearby experience store to experience the comparison and selection, choose the machine you not only need to parameters, but also need to see whether the appearance design can be and whether the warranty is convenient and perfect.

Serve**. If your problem is not solved, you can complain, put forward your valuable opinions, and then transfer to manual service.

Dear Lenovo users, hello!

In the actual use process, there will be a variety of reasons that can cause the computer to generate a lot of heat, and even indirectly cause computer crash, blue screen, power failure and other failures. To deal with such problems, it is necessary to investigate them one by one according to the actual situation to determine the specific cause of the failure. A typical case can be found with the following factors:

The aging of the heat dissipation grease of the host leads to a decrease in thermal conductivity.

The accumulation of dust on the heatsink and fan of the host computer affects the heat dissipation processing capacity.

Viruses in the operating system cause the computer to be overloaded for a long time.

The operating environment temperature of the host is too high.

The ventilation of the main engine vent is poor or even blocked.

Normal performance caused by certain software (or: games).

Based on the above possible factors, it is recommended to improve the ambient temperature during the inspection process and use it in a good ventilation environment. If it is invalid, you can check whether the host load (such as: CPU, graphics card) is too high, and secondly, you can adjust the power management mode to "performance balance" mode for use, and if necessary, you can contact the service station to clean up the dust and replace the thermal grease.

1.Improve the working environment and ventilation conditions.

In general, it is recommended that the host computer work between 10-25 degrees Celsius, and too high or too low ambient temperature will have adverse effects on the host. At the same time, check whether there are any obstructions around the heat dissipation holes of the host, especially the notebook should not be placed on a soft surface (such as a quilt) to prevent the heat dissipation holes from being blocked. If this is the case, you can place the laptop on a flat desktop and observe whether the fault is eliminated.

2.Check CPU (or: GPU) usage.

If the host CPU (or GPU) is constantly working under high loads, it will bring more heat due to increased power consumption. Even if the host fan is running at full speed at this time, it will not be able to dissipate all the heat in a short period of time.

This is normal (note: except for the high load caused by viruses), and the easiest way to deal with this phenomenon is to end a program that is using CPU resources or a game that is using the GPU resources of your graphics card.

Note: If the resource occupation caused by the virus is used, you can upgrade the anti-virus software to conduct a comprehensive scan for testing.

3.Change the power management mode to "Performance Equalization" mode for use.

In addition, you can refer to the instructions in the user manual to change the mode of the power management software to the "Performance Balance" mode. This mode can achieve a balance between power consumption and performance without causing performance degradation to the host. Some of the power management software can be accessed by referring to the following links:

Yangtian version: ThinkPad version:

4.Contact the service outlets.

If the above methods still cannot be effectively improved, this situation requires the professional engineer of the service station to check whether the thermal grease of the host is aging, and in some cases, the dust blockage caused by environmental problems will also cause poor heat dissipation.

Note: Non-professionals should not disassemble the host by themselves.

Therefore, in this case, it is recommended that you bring the host and purchase invoice and send it to the nearest Lenovo service outlet for further testing.

Advantages: strong performance, comfortable buttons, advanced design concept, good heat dissipation.

Disadvantages: It is inconvenient for upgrading, and the entire back cover must be removed, and the workmanship details have been improved.

The specific configuration of Lenovo Y400 is as follows:

Y400 game performance is pretty good,**It's okay (leaving aside the American version, because the American version is better and cheaper), and then the workmanship of the national bank is not so exquisite. Let's not mention the heat or anything, of course the heat is inevitable with such a high performance. Then,If there are acquaintances in the physical store, it's the best.,You can see if there are any bad spots and other quality problems.,If you shop online, of course, it's recommended to go to the **American version.,If not, it's okay with Jingdong or something.。

This is not necessarily, the profit in the mobile phone is already very high, we laymen don't understand, it's easy to be fooled.

Some of the things delivered are not the same, and there is a price difference!! Some of them are high, but they can also be priced.

Others will also be cheaper to find acquaintances!!

Hello, buying in large ** and specialty stores are guaranteed for your interests, with Lenovo computer purchase precautions:

1.Please try to start the computer and test the functions and buttons before taking the machine away to avoid problems;

2.Please try to issue a regular national tax department invoice, Lenovo's warranty calculation depends on the invoice time, there is an invoice that is calculated from the purchase date shown on the invoice, no invoice is based on the production date for repair, in order to avoid your purchase when you are far away from the production date to damage your interests, please let the merchant issue a formal invoice (invoice, not a receipt!) The receipt cannot be used as a proof of purchase and is not recognized and protected by the Three Guarantees Law);

3.Please carefully check the items sent by the machine seal and packing list to avoid inconvenience to your use;

4.Regarding the purchase of Lenovo computers, any items outside the computer carton packaging, such as individually packaged mice, headphones, speakers, USB flash drives and other digital equipment, if they are included with the purchase but not listed in the packing list, please be sure to note that Lenovo does not provide warranty for such items, and you need to confirm the warranty with the dealer, and the failure is generally 1 year to be repaired by the dealer to avoid inconvenience to your use, please be sure to know. \

At present, 400 is relatively cheap, I bought it for 5,000 oceans a month ago, and I have a three-piece set of tickets!
