How to Protect Your Laptop Just in Case You Lose It

When using a laptop at a public place, such as a coffee shop or library and when going to the restroom there, you may have an experience that you ask a person to watch out your stuff. Most of the notebook users don’t want to imagine losing their laptop. If they lose it, they can buy another laptop. However, vital data on the lost laptop can’t buy with money.

Here is a way to protect your notebook just in case you lose the laptop; this is based on a Windows operating system.

1. Click “the Windows Start menu.” If you use the edition of previous Windows 7, select "Run" in the start menu tap. 

2. Type “CMD” in the search box and then press enter: CMD stands for command prompt.

3. Type “IPCONFIG/ALL” at the prompt and then press enter: IPCONFIG stands for Internet Protocol Configuration.

4. Two physical addresses are crucial. One is for wireless LAN adapter, and the other is for Ethernet adapter. Take a picture or capture the screen, and then keep it. If your laptop is stolen, you can find it with theses MAC (Media Access Control) addresses after reporting to the police. However, it is not 100% guaranteed because the MAC addresses can arbitrarily change. If its wireless LAN card or its mainboard is exchanged, its tracking with the physical addresses you have is difficult; the exchanged notebook has new MAC addresses. 

5.  Take a picture the serial number of your laptop on the bottom and keep it. It will help you to find the lost notebook.

The most important thing is that you should not lose your laptop and that you should make a periodic backup of your significant data.
