What should students pay attention to when buying laptops? Heat dissipation, sound quality and picture are all important. How to identify them? thank you

The quality of a notebook depends not only on the hardware configuration, but also on the quality of each hardware and the performance of the whole machine. Compared with foreign products, domestic notebooks started late, so they are slightly inferior to world-famous brands in overall performance. Compared with ordinary people, college students are a special group, often limited by the consideration of economic interests. They can only choose domestic books with high cost performance or imported books with low price. Therefore, we must carefully consider and act cautiously when purchasing. So how can I buy a satisfactory notebook? Also consider from the following aspects:

First, look; Second, touch; Third, sense of smell; Fourth, listen; V. Operation

Look at it first, that is, look at the color of the shell and hardware of the notebook first. "Is there a screen and dots when the monitor is turned on?" Then see if the production date, serial number, serial number and manufacturer of each hardware are the same as described before purchase.

Second, the feel, a good notebook, does not slip to the touch, and the keyboard is comfortable and natural to use (Ibm) but the notebook with poor quality is either too slippery or too dry to the touch (some shells are hand-ground).

Third, I smell that new notebooks often smell of steel paint, which is more authentic; The poor quality of notebook steel paint is more pungent. Note that a 90% new computer has almost no smell of steel paint.

Listen, after you turn on the new machine, you have to listen to it first, okay? Is the fan loud? Is the machine sound stable? Is it abnormal to type "sound quality" externally? When you find problems, you should give them back to your boss in time.

Verb (abbreviation of verb) operation: First, after the system is installed and turned on, you can download a 360 security guard, check the configuration through "360 Hardware Master" and evaluate the "heat dissipation" performance of the machine. You can also use my computer-properties-hardware-device manager to check whether all the hardware is working properly. Of course, you can also check the sound quality, image quality and the whole machine comprehensively and carefully by entering DOS or downloading other hardware detection software (such as Everest).

After the above five points are completed, you can safely take the baby home. Generally, new notebooks have a probation period. If there are no accidents in the book within the specified months, congratulations, indicating that the purchase is successful.
