How do second hand computers determine whether they are mining m

1. Take it apart. Look at the st inside. If you have a SSD, you can look at the number of times the SSD is charged.

2. Computer brush is very easy, as long as the motherboard BIOS brush on the line, but Master Lu is based on hardware, not just read BIOS information.

3. The original machine is also saved by the manufacturers, so it is not significant to pursue the original of the second mobile phone
more powerful manufacturers will have spare parts query libraries. Each component has a code, which can be found online, but the code is pasted, so it's easy to make a fake.

4.

The way to distinguish second-hand computer:

1, look at the appearance, the appearance has serious wear and tear, paint off, it is a second-hand computer

2, if it is a brand or laptop, check whether there is any trace of unpacking

3, to see how long the hard disk is used, you need to download software to help you view

take Master Lu as an example:

1, download and install Master Lu

2, use hardware detection and hard disk information to check the number of hard disk read-write and use time. Generally no more than 5 hours of total ration, is the new machine

5. When you buy a second-hand computer,
you can see its wear degree from its appearance,
you can't see the wear degree from your heart's computer,
see if there is st on it,
notebook keyboard and other places,
you can ask the buyer to take it apart and show you the hardware inside,
you can see the new computer,
you can also use some software to help you check it Test the performance of the computer
second hand computer is easy to identify
the key is the performance of the second-hand computer! It is suggested that you find a friend or relative who knows this when buying a computer to buy it with you
don't be cheated by the boss who bought the computer! Hope to help you!

6. 1. Turn on the computer and click the run button under the start button
2. Enter CMD in the run box

3. Click OK to open the black dialog box

4. Enter systeminfo command in the pop-up black dialog box

5. Click the enter button on the keyboard to wait for running

6. After the operation stops, turn to the top, check the initial installation date, and check whether it is consistent with your purchase time.

7.

1. Look at the serial number. Most notebook bodies and batteries should have the same serial number. If the serial number of the battery is inconsistent with that of the host computer, the notebook may have been replaced; In addition, when purchasing foreign brand notebook procts, whether the serial number of the body is consistent with the battery and the outer package is a very important basis for checking whether the proct is parallel procts. We should know that foreign parallel procts can not enjoy the quality assurance at home

2. If there is a mark, it means that the notebook anti-theft lock has been inserted, it is very likely that the prototype has been made

3. If there is wear and tear and very dirty, that has been used, proction line workbench is not so dirty

4. Look at the cooling fan. If the fan blade has thin st, it means that it has been used for more than a week

5. Look at the proction date. Three months ago, the book is still on the market, we should pay attention to it. Electronic proct sales update speed is extremely fast, it is impossible to let a capital pressure in the channel for such a long time

6. Look at the keyboard. The keyboard in the new book is clean, but it won't light up. There will be st in the gap of used notebook keyboard, and several commonly used keys will be polished

7. Look at the screw. The screw has been removed. It must be second-hand

8. Look at the gap. For example, the small gap between the AB side of the notebook screen, the gap between the CD-ROM drive, and even the interface of modem and PCMCIA card, if st can be found, you can be sure that the prototype has been placed and not sealed

9. Looking at the details, there will be scratches or finger marks on the turnbuckles of many refurbishing machines, and there will be st at the interface of the notebook. Look carefully or smell hard to see if there are traces and smell of st

Check the power on times and time of hard disk with software

11. Packing seal (although there are too many fakes now, just blow it off the plane)

8. Check whether the motherboard capacitor has yellowing traces. If the accessory capacitor of Nanqiao chip has yellowing, it means it has been renovated.
