This problem has been discussed in the past, but many methods are not practical and may not all be effective. This article aims to provide practical advice, especially for those who live in school or bed. After all, a notebook is worth W meters, and not everyone can afford it. I lost an HP book in 2005, and the thief was an idle person outside the school. He broke into the house and stole two books. There were two guards in the corridor! My classmate MM lost a Sony of 1.7W in the same month, that is, she went out to eat for 20 minutes and put her notebook under BT in her dormitory. Uncle policeman gives some advice for your reference. 1, be sure to lock the door, use the key, and don't push. At this point, several students in the dormitory should do a good job of consulting. A person's carelessness can have serious consequences. 2, it is best to lock in the cupboard, what lock is not important. Mainly to create trouble for thieves. 80% of the sneaky things are on the surface. The longer the crime lasts, the worse it will be for them. 3. If it is a small book, it is recommended to carry it with a backpack. It is not easy to forget your shoulders and it is more labor-saving. Don't show off in the library classroom. If you want to use it, take it with you when you go out to the bathroom. A classmate even fell asleep at his desk and lost a notebook! 4. The invoice warranty card and notebook are opened separately, in case of loss reporting, there is a basis. 5. If there are really Mi people, the 2W notebook can be equipped with a good lock or a good cabinet, so don't be too ostentatious. Not afraid of thieves stealing, but afraid of thieves thinking! 6. The advantage of having a good relationship with classmates in the dormitory is that everyone can supervise each other, at least not because of a bad relationship. 7. Even if you go to the toilet or wash, you can't leave your bedroom unlocked when no one is around. It only takes about 2 minutes for a thief to commit a crime. The following idea is invalid or dangerous: 1, just a few minutes, it doesn't matter. The risk coefficient is 9, and the reason is shown in Figure 7 above. 2, there is a password, a fingerprint, and a hard disk lock. What am I afraid of? The risk coefficient is 10. It is reported that the average education level of college dormitory thieves is less than the first grade of junior high school, and they simply don't know what an invisible lock is. The books stolen on the black market are only 2K yuan even if T43 is high. Locked the door with the key, because it was too much trouble, and it was not locked in the cupboard. Risk factor 8. University dormitory locks basically do not have any anti-theft function. Most of them can be poked with ID cards. There is a guard in front of my uncle's house downstairs. Risk factor 7. Grandpa and guards are at the door every day, but they play a deterrent role, and their role is equivalent to the portrait of Guan Gong on the door. If you sit there for ten years, what is vigilance? 5. Use a computer lock. Risk factor 4. It is still very dangerous, because no thief will have no tools. 6, the book has been used for so long, it is old, it should not matter. Thieves will find you when you least expect them. And a book is only a few thousand dollars at worst, and money is not burned like this! 7. Added on the inside thief: In addition to getting along well, you should be careful at ordinary times. Don't show your attitude towards JS, even if it's a 2W book, let alone a 3K book. It's best to avoid jealousy. Take this little notebook with you. Large notebooks can be locked in cabinets or suitcases with passwords. The suitcase is locked on the railing of the bed or cabinet with a chain lock (used to lock the bicycle) (preferably an iron railing, at least stronger). At present, many students in universities are addicted to stealing. When they are arrested, there are often more than a dozen XX in the cupboard, and they can't hold them. I have seen a photo, when the police pulled the door, the laptops in the library piled up like old books. Generally speaking, if it is an inside job, it is possible to get it back. But if it's in the office or just in the field, congratulations, you can take this opportunity to upgrade. Because in this case, you have nothing to do except report the case, and then you will sink into the sea after filing the case. But losing things is always troublesome, isn't it? So it's still an old saying, be careful, be alert and guard against thieves! \
