Universality, Xi' an Lucky Pig and several colleagues have in-depth understanding and field observation, and found that problems may appear in the following aspects.

First of all, we all know that the hardware equipment reaches the standard from the five people with the lowest number of punch cards, and the equipment is continuously powered on and off for five days. Although the requirements seem low, this is precisely the problem of many small enterprises. Because some enterprises, after work, in order to save electricity, will directly turn off the company's door after turning off the lights and computers, resulting in the direct disconnection of hardware equipment.

When you open the main brake at work during the day, the person in charge of the enterprise will think that it has been used all the time, without realizing that the equipment may not meet the standard.
