A few years ago, my daughter-in-law changed this ASUS U3300F notebook for the convenience of work, the processor is the eighth generation i7, and it also has MX150 independent graphics card, and I was deeply attracted by its appearance at that time. Because it is an extremely narrow bezel design, the 13.3-inch screen looks like it is embedded in a 12-inch mold, taking into account both practicality and portability.
Previously, I wrote this notebook in a series of articles on second-hand thin and light books, and I mentioned a handheld vacuum cleaner for cleaning dust, and many people asked me to recommend vacuum cleaners. Forget it, today with the ash cleaning tutorial, let's talk about how to hold a vacuum cleaner. My machine has an integrated back cover, and you can see the hidden screws by picking open the top two foot pads on the back.
Let's talk about why the notebook should be cleaned first, because the notebook fan will absorb a lot of cotton wool-like objects after a long time, and over time it will "block" the fan, resulting in the fan in a state of extreme speed, and the CPU heat is still very high, which is why some people say that the laptop fan is very loud, and the machine is still very stuck. Once the CPU temperature does not go down, it will naturally reduce the frequency frequently, and it is recommended to clean the fan once a year.
In the past, the old-fashioned notebook was disassembled and cleaned, often to dismantle eight pieces, such as the Dell 700M notebook I used in 08, each time I had to disassemble the keyboard first, then remove the screen frame, and then remove the motherboard, and finally clean the ash, and it took 2 hours for skilled workers. Nowadays, ultra-thin laptops are too simple, and just opening the back cover is half the battle.
After removing the back cover, just use the handheld vacuum cleaner to vacuum the ash with the fan. My green vacuum cleaner is from Laiben, which cost 68 yuan in February 2021, with a nominal suction power of 8000pa and a power of 120W, which is more than enough to absorb fan dust. But be sure to use a long-bristled brush, otherwise dust and lint will not easily fall off.
After the fan is cleaned, see if the top air outlet is blocked by dust, and finally you can install the machine. After each ash cleaning, the notebook can be restored to the heat dissipation effect and low noise level of the new machine, and the entire ash cleaning process is completed in five minutes from unpacking, ash suction to shelling.
I also have another black Tuhu car vacuum cleaner, and I have dusted the Toshiba X30-F notebook before, and the effect is clear at a glance. This vacuum cleaner has a nominal suction power of 4500PA and cost 49 yuan in February 2020. In short, according to my measurements, as long as the handheld vacuum cleaner with real suction power of more than 4000PA can easily clean the notebook, and the average price of the new is more than 50 yuan. As for the small factory goods that are too cheap, most of them will falsely mark the parameters, and it is difficult to give pertinent opinions.
