What should I pay attention to when buying a laptop?

This question is not easy to generalize, depending on what needs you have, generally speaking, Japanese manufacturers are good at making light and thin, like Sony, Toshiba, and European and American manufacturers are better at performance, like IBM, HP, Dell.

I should have bought more than a dozen notebooks, I originally bought two IBM, both performance and appearance I think are very good, at least it is different with other notebooks, but unfortunately now it is not so easy to buy pure IBM, it has been attributed to Lenovo. I've also bought three HP's, and the workmanship and performance are also good, but it always feels a little worse than IBM, but one of the biggest advantages of HP or Compaq's notebook is that his speakers are generally quite good, and he used JBL and Harmon Kardon's, and now he should use Altec Lansing, and the sound is very good. I bought one from Sony, and the display is very good and thin, however, the keyboard is on the soft side.

Other dell has no characteristics.,It seems to be cost-effective.,But I don't feel it.,I don't think the workmanship is very good.,And Lenovo.,I think it's similar to Dell.。

IBM's good, good performance, high safety factor, the disadvantage is that the style is too single (but this is also a feature of IBN).

The price is equally expensive.

First, the first thing to do when you buy a new notebook is to use the battery in the notebook cleanly, don't start charging when you don't see the number of points in the battery, which is not right. The factory power of the laptop is to protect the battery, and it must be used up before it can be charged.

Second, the first three charging times of a newly bought notebook should be between 12 hours and 14 hours, and each time it is fully charged, it must be used up before the second charge.

Third, the first three charges of the newly bought notebook are very important, although the current battery has no memory function and can be used casually, but the battery is a battery after all, and a good start can determine the future life of your battery. Whether it is a previous battery or a current battery, you need to pay attention to this.

Fourth, if the newly bought notebook has a battery protection program, adjust the battery to the most common battery life mode.

This mode is suitable for users who use the adapter for a long time, not for those who use batteries, so if your computer is played with a power source, then be sure to set it to the optimal battery maintenance state.
