Teach you how to deal with the noisy laptop, In the dead of night, what accompanies you is not the crisp sound of typing on the keyboard but those "hissing and clicking" noises. Can you tolerate it? How to better reduce noise and allow users to use laptops in a quiet and comfortable environment has become the topic of our discussion this time.
To better reduce the noise of laptop operation, you should first understand the source of noise when the machine is running, and then take appropriate measures to solve the problems one by one! In fact, the noise of laptops mainly comes from hard drives, fans, optical drives, etc. Components, if you want to reduce noise, you should naturally start with these components.
What to do if your laptop is noisy: Hard drive
The noise of the hard drive mainly comes from the magnetic head. First, the magnetic head is reading the disk. The other is the "hissing" sound caused by friction with the disk, and the "thumping, clicking" sound made by the hard disk thermal calibration. This phenomenon can generally be solved by upgrading the latest Fimeware program. For example, the HITACHI hard drive equipped in early Thinkpad notebooks had obvious thermal calibration sounds. At first glance, I thought the hard drive was broken. In fact, the problem can be solved by downloading and refreshing the latest Fimeware program from the IBM website.
Hard drive packaging is also the main reason that affects the sound volume of hard drives. Some manufacturers use a special packaging method for hard drives, which effectively reduces the noise generated by hard drives, such as Panasonic's CF - This is the case with the R1 notebook. Its hard drive does not use the public version hard drive bracket design, but is wrapped in a special sponge material, which not only protects the hard drive from external impacts, but also provides certain sound insulation and noise reduction. effect. We can also follow the example of CF-R1 and wrap a thin layer of sponge on our laptop hard drive to reduce noise. This method is very suitable for notebooks such as TP600 that use 12.5mm hard drives. You can use a standard 9.5mm hard drive instead of the 12.5mm hard drive, so that there is free space to put the sponge.
What to do if your laptop is noisy: Fan
The fan of a laptop is different from that of a desktop computer. Computer fans always start running at high speed as soon as you turn on the power; notebooks are an exception. Generally, the fan only starts to rotate when the temperature reaches the limit predetermined by the BIOS, and often it is not running at full speed and is divided into several speeds to run. . This is also considered for the purpose of power saving and noise reduction. Generally used laptops due toAfter being used for too long, a large amount of dust and dirt accumulate inside the fan. When the fan rotates, the sound will be extremely loud due to dust blockage. Sometimes dirt will even entangle the fan blades, causing the fan to fail to work properly, with disastrous consequences. . Since there is no unified standard in the industry and the internal structure of each notebook is different, it is not practical for notebooks to replace the fan with a new one. The easiest solution now is to clean the fan yourself by using a clean cotton ball. Use alcohol to carefully clean the center of each fan blade and shaft. It should be noted that do not add any lubricant to the fan shaft. This is mainly because the notebook fan is different from the desktop fan. It uses a high-end self-lubricating fan, which is different from the common ball fan, so oiling not only causes It does not have any effect, but will affect the normal operation of the fan.
After the dust is cleaned, we also need to consider the problem of thermal deformation of the fan. Since the fan rotates at high speed for a long time and blows out hot air to achieve the purpose of heat dissipation, the plastic blade surface will produce thermal deformation. I have mentioned above that it is impossible to replace the fan. We can consider cutting off the deformed fan appropriately, so as to solve the noise problem caused by uneven operation of the fan blades.
What to do if the laptop is noisy: Optical drive
The structure of the optical drive of a laptop is different from that of a desktop computer. The central axis is fixedly rotating. This design is often seen on the CD players we usually use. Its noise mainly comes from the wind noise generated by the high-speed rotation of the disc. If your disc is not flat enough or you use a pirated disc with rough workmanship, the sound will be more obvious, and there will be very loud vibrations from time to time. In this case, you can try to change to another disc.
For machines with non-removable optical drives, this approach may not be feasible. We can only reduce the noise through software methods. The German company Nero has produced a noise reduction software called NERO Drivespeed. In fact, its noise reduction principle is very simple. It uses software to adjust the speed of the optical drive to reduce noise. The speed of the optical drive can be set arbitrarily according to your own optical drive speed. After running Drivespeed, minimize to the taskbar, open the playback software and enjoy the DVD without annoying noise. If you want to restore the original reading speed, you can Select "Maximum" in the "Read Speed" option, and the optical drive will return to high speed.
Summary
With such an optimization, I believe it will definitely reduce a lot of noise in laptops. If you are still suffering from notebook noise, then try the above method of taking a snapshot.
