To the second-hand market , I can't sell it for a good price .
Considering that the computer I use in my daily work lacks a secondary screen , It would be better to have a mobile hard disk . Can this old laptop be reused ？
It seems to have been scrapped , You can actually create a secondary computer screen 、 A wireless card 、 A mobile hard disk and an external CD-ROM drive , It all depends on your imagination and hands-on ability .
Computer sub screen
Many users who are engaged in content production have a great demand for computer sub screens , Create on the home screen , The secondary screen serves as a reference .
Buying a single screen is an extra budget , If the demand for the secondary screen is not high , You can build it in my way .
When the computer can be turned on , Two computers should meet the same network environment 、 At the same time to install Windows 10 System .
Click on the notification in the lower right corner , Turn on the projection , Select extension , The main display and the secondary display are completed .
If the computer can't be turned on , But if the display still works , The laptop display can be removed separately . The advantage is that it saves space on the desktop , But it needs hands-on ability .
You need to buy additional drive board 、 Control panel 、 power cord 、HDMI Line , The cost is less than 100 element .
Next, just put these together , believe me , It's not as hard as you think （ I really can't find professional guidance ）.
External wireless network card
After confirming that the network card can be used normally , Remove the network card , It's about this shape in the picture .
Network card is not enough , You also need to buy an extra adapter , The cost is about 12 yuan , Very cheap .
Connected together, it can be installed on the main board of the desktop computer , It comes with Bluetooth .
External optical drive
Laptops used to come with CD-ROM drives , Now it's almost out of print , Basically, I don't need this .
But just in case , It's always useful to keep it , The external connection method is similar to the network card .
This can be dressed in no hurry , It's not too late to install it when it's time to use it .
mobile hard disk drive
The key is coming. , The hard disk is the data center of the computer , It's the most important part for me .
There may be many precious memories and important learning materials in it , It's hard to start the computer to see it because it's aging , But it doesn't affect us to use it as a mobile hard disk .
The reuse of hard disk is very simple , Just buy an extra hard drive case , The cost is less than 100 element .
The green link hard disk box I chose is very convenient to use , The power adapter and USB cable , You can use it wherever you go .
At the time of installation, I was also worried about the size incompatibility , It turns out I'm worried too much , The hard disk case is compatible with 2.5/3.5 Inch hard drive .
Then we measured the speed , I want to try the double speed increase of the hard disk case , It can really reach the full speed of mechanical hard disk 450MB/s.
After all, the service life of mechanical hard disk is limited , I'll turn it off when I don't use it . But I found that this hard disk box also has an intelligent hibernation function ,3 Minutes no operation, automatically enter sleep state , Just met my requirements . It can reduce the wear of hard disk , Minimize the loss of hard disk .
This is about notebooks “ waste ” Of 4 There's a way .
Other people's old notebook can turn waste into treasure , What about you? ？
