Super-Resolution Of Laptop Noise Reduction Maintaining Articles
Super-resolution of laptop noise reduction maintaining articles
Night in the dead of night, accompanied by the beating of your keyboard is not crisp sound but are "hissing, Kaka," the noise, you can put it? How best to reduce noise, allowing users in a quiet and comfortable environment, use of laptop computers, has become the Dell Inspiron 9400 Battery of this discussion we are.
To reduce the better laptop running noise, first of all should understand the source of the noise when the machine is running, and tackle problems can be solved! In fact, the notebook's noise, mainly from hard drives, fans and drives and other components to reduce noise, These components should naturally start with the.
Hard articles
Noise mainly comes from the hard disk heads, one head when reading optical discs and disc friction has issued a "hissing" sound, the other is the hard thermal correction has issued a "strategic dengkou, slightly dengkou" sound, this phenomenon can generally be by upgrading the latest Fimeware procedures. For example early in the Thinkpad notebook with a HITACHI drive has obvious thermal calibration voice, at first glance thought it was really bad hard drive, in fact, as long as the IBM Web site to download and update the latest Fimeware procedures, the problem can be solved.
Hard disk sound package also affect the size of the main reasons, some manufacturers use a special hard drive packages, effectively reducing the noise produced by hard drives, such as Matsushita (Panasonic) of the CF-R1 Notebook is the case, it The hard drive does not use the public version of the hard disk bracket-style design, but with a special sponge material package, not only to protect the hard disk from external impact, but also played a certain noise, noise reduction effect.
We can also follow the CF-R1 practice in their own laptop hard drive wrapped a thin layer of foam to achieve lower noise. This method is very similar to the TP600 suitable Dell Inspiron 6400 Battery such books by 12.5mm hard drive, you can use standard 9.5mm 12.5mm hard drive to replace hard disk, so have a spare place to put a sponge.
Fan articles
Laptop fan is different from desktop fan, desktop fans generally are when you turn on the power of the moment, fans began to high-speed operation; notebook is an exception, generally only the temperature reached a predetermined limit BIOS, the fan only began to turn, and often is not fully functioning, divided into several files to run speed. This is for the purpose of energy saving and noise considerations. The use of a general second-hand laptop for too long, the fan a lot of dust accumulated inside and dirt, turning often, when the fan dust plug, the sound is particularly great, and sometimes even dirt will cause the fan blades can not be wrapped work lead to disastrous consequences.
As the industry has no uniform standard, the internal structure of each different laptop, so replacement is not practical for a laptop fan, and now the simplest solution is to clean up their own fans, and method is to use a clean cotton ball dampened with a Alcohol carefully cleaning each piece of rotor blades and the center. Note that the hinge Do not add any lubricant fan, notebook fan, mainly because the fan is different from the desktop, it uses a form of self-lubricating high-grade fan, the ball is different from the common fan, so oil is not only not have any effect, it will affect the normal operation of the fan.
After the dust cleared, we have to consider the issue of thermal deformation of the fan, as fans in the long high speed, blowing hot air to achieve the purpose of cooling, plastic leaves will produce thermal deformation. I have already mentioned above, the replacement fan is not likely, we may consider appropriate to deformation of the fan cut off the way, so that we can solve the uneven operation since fan noise problems arising.
CD-ROM articles
Notebook drives and desktop computers are not the same drive structure, using the fixed rotation axis, so that the design used in the usual CD player we often see on its noise is mainly from the CD-ROM produced by high-speed rotation The wind noise. If your CD is not smooth or rough the use of pirated optical discs work, the sound will be more obvious, and not also yields a very large shock, in which case, you can try a change of the other discs.
The drive is not removable machine, this approach may be feasible, we can only approach through software to reduce the noise of the. Germany Nero company has produced a noise reduction software called NERO Drivespeed, in fact, the noise reduction principle is very simple way to adjust the software CD-ROM drive speed in order to achieve noise reduction Dell Inspiron 8000 Battery. Drive speed is the speed drive according to your own arbitrary set, after running Drivespeed, minimize to the taskbar, open the player, enjoy the DVD would not have the annoying noise, and if you want to restore the original reading speed, can "Read Speed" option to select "best", then drive it into a high speed of recovery.
Summary
Optimization of such a pass, I am sure the laptop will reduce a lot of noise. If you still suffer from laptop noise, then it quickly according to the above methods try.
The past two years more and more users are beginning to realize the benefits of portable, notebook computer sales momentum and therefore can not block stiffness. Laptops in the past has been to office systems to appear, there are many companies starting to focus on its entertainment, but audio performance is still not satisfactory. To keep the sound to become the bottleneck of entertainment notebooks, we have created the topic dedicated to those who like games and video entertainment notebook users. This topic is divided into three parts, including: laptop sound card, speakers and headphones, let us first look at notebook sound card. Why are hard to break the audio quality?
Notebook audio quality is difficult to break through the main reason why the term is limited to the size of notebook computers. In fact, the built-in sound card notebook, especially the latest Sonoma platform, the quality of the audio chip is sufficient to meet the everyday needs of most users. But because the size limit, the internal structure of very compact notebook computer, audio, and other parts of the circuit are also close together, like the circuit, to achieve the good effect of anti-electromagnetic interference is difficult, in many notebook Sony VGP-BPS2 battery with high-quality codec chip is no good.
On the other hand, notebook computers can only try small speaker and speaker box is not enough space, it is difficult to play out the speaker should have the effect, to say nothing of the bass. Like in some well-designed high-end notebook computers use 4.1 sound system, but the results are still far from a desktop PC. And because laptops are usually only the headphone jack, so even with well-designed audio circuitry, can not external speakers for better sound quality.
Go?
For desktop machines, the majority of users because of cost will choose the better sound quality, they do not consider the independent board sound card, so a huge price difference and the relatively small difference in sound quality so that most people can not accept an independent sound card . Although the desktop machine and sound card there are circuit design and anti-electromagnetic interference, but much smaller than notebooks, even one not understand the audio of people can easily feel out of the rough notebook audio.
Transformation of laptop audio, of course start from the core of the sound card, but limited to the laptop itself features built-in sound card is difficult to achieve high standards, many audio manufacturers have seen this, have introduced USB, IEEE1394 and PCMCIA interface to the external sound card. Notebook audio design is not a breakthrough, we only rely on these products to improve the quality of their audio output.
It is worth noting, however, this part is more for games and music lovers, enthusiasts and even professionals, because they are harsh audio quality requirements. For ordinary users, the majority of high-quality laptop audio output quality is acceptable, so these users should be concerned about is that we will be gradually introduced after the two Acer Aspire 3000 Battery speakers and headphones products.
