If your laptop is used for a long time, it is inevitable that there will be dust, and if there is too much dust inside the computer, it may also cause a blue screen! So you must remember to clean your computer in the right way.
The easiest way I generally use is to use a cleaning kit to clean.
For the screen, spray the cleaner on the microfiber cloth, and then wipe it back and forth. Do not wipe in a circular motion, but gently wipe in a regular and fixed direction. If the screen is too wet after wiping, you can use a dry sponge to moisten it with mineral water and then wring it out and wipe it again. Don’t use tap water.
For the keyboard, you can turn the keyboard upside down first to see if there is any debris that naturally falls, but it seems that there is generally no such large debris hidden in the gap of the keyboard. If you have a vacuum cleaner, it’s best to wash it carefully. If you don’t have it, it’s okay. Generally, the cleaning kit will have a small brush. I usually use a small brush to sweep the gaps in the keyboard. If there is a keyboard membrane, no debris will enter.
This is my usual super simple external cleaning of the computer, in fact, everyone must have this awareness!
There is another very important point. Don’t let things get into the jacks on both sides of the laptop!
