What should students look for in a laptop? Heat dissipation, sound quality, and graphics are all important, how should I recognize them? Thank you!

A laptop is not only good or bad depending on the hardware configuration, but also on the quality of the hardware and the performance of the machine. The domestic notebook compared to foreign objects, is a late start, so in the overall performance is slightly inferior to the world famous brand. Compared to the general public, college students as a group is more special, often limited by the economic benefits of the consideration, they can only go to choose a cost-effective domestic notebook or imported low-cost notebook. Therefore, in the purchase of the time must be carefully considered, careful. So how can you buy a satisfactory notebook? But also from the following aspects to consider:

A, see; two, touch; three, smell; four, listen; five, operation

A, see, is to look at the laptop shell as well as the color of the hardware is new or not new?" Display open with or without screen and point?" Then look at the production date of each hardware, number, serial number and manufacturer is not the same as described before purchase.

Second, touch, a good notebook, touch not slippery, not dry, the keyboard with a comfortable and natural (Ibm) and the quality of the notebook is not very good to touch either too slippery, or too dry (some shells are abrasive).

Three, smell, new laptops tend to have a steel paint flavor, and more authentic; and poor quality laptop steel paint flavor is more pungent. Note that a 90% new computer its steel paint flavor is almost unheard of.

Four, listen, open the new machine, to listen to the first machine does not sound? Fan sound? Machine sound is not smooth? Playback "sound quality" is not normal? If you find a problem, we must give timely feedback to the boss.

Fifth, the operation, first installed the system boot, you can download a 360 security guards, through the "360 Hardware Master" to view the machine's configuration and evaluation of the machine's "cooling" performance, etc. You can also download the "360 Hardware Master" to view the machine's configuration and evaluation of the machine's "cooling" performance. You can also through the "My Computer" --- "Properties" ----- "Hardware" ------- "Device Manager "to see if all the hardware is running normally. Of course, you can also enter the DOS or download other hardware testing software (e.g. everest) to conduct a comprehensive and detailed testing of the sound quality, picture quality and the whole machine.

After the above five points are completed, you can rest assured that you can bring your baby home, new laptops generally have a trial period, if there are no accidents in the specified months, then congratulations, that the purchase is successful.
