IT 168 has been using Founder Yi and H500 as its exclusive features for some time, which is consistent with the positioning of Founder Company. H500 successfully created the myth of desktop replacement with its superior performance in notebooks. As can be seen from H500, domestic notebooks have completely reached or surpassed some foreign classic desktop substitutes in performance and overall configuration. What is the charm of H500? The author will lead you to appreciate it.

First of all, from the appearance, H500 is a rough design. The silver top cover and the silver dark gray color scheme make it look generous and calm. However, from the details, the whole machine adopts ABS plastic shell, but many joints have burrs and are a bit rough. However, judging from the painting process, this product is still very good, with uniform painting and good feel. However, the degree of wear resistance is general, which has a certain relationship with the plastic shell used in the fuselage. If the magnesium-aluminum alloy shell is replaced, not only the appearance will be improved, but also the wear resistance will be improved. It is estimated that Founder's designers consider that the heat dissipation of metal shell will directly reflect on users, causing discomfort, so it is wise and understandable to use ABS engineering plastics.
When you turn on the screen of the machine, the user will find that the front end of this machine is somewhat similar to Sony's GRU7CP, and the front end of the armrest has an obvious oblique angle. The advantage of doing this is that users will not feel uncomfortable when working with their hands on the handrails, and at the same time, the visual thickness can be reduced, so that users will not feel very thick when they first see the H500. This design has been used by the classic Sony R505. Many IBM models are also using this design, and such details can be thought of by the founder. It can be seen that this is a deliberate work. It is such a small detail that users can better feel the charm of a product, which is also lacking by domestic manufacturers at present.
Appearance is not the specialty of this product, but powerful performance is the most important feature of this product. H500 uses P4 3.06GHz hyper-threading processor (note: this is a desktop processor).

Equipped with a single 5 12MB DDR memory, the display subsystem adopts the most powerful ATI MOBILITY RADEONTM 9000 AGP graphics accelerator card in the notebook at present, and is equipped with an amazing 64MB DDR display size. 3D is a top-class notebook graphics card with strong performance, delicate picture and fast mapping speed.

Although ATI has released the 9600PRO display chip, it has not been officially put into use. At present, the most powerful display chip in the finished notebook on the market is ATI MOBILITY RADEONTM 9000 GL, which is a special version of a graphics server. When running 3D games, the speed performance is not very good, so it is not suitable for home use. The product really suitable for home use is ATI MOBILITY RADEONTM 9000. H500 adopts the top version of 64MB, which is enough to add icing on the cake to this product. This can be seen from the author's informal test. This graphics card, with 3.06GHz hyper-threading processor, achieves a good result of nearly 7400 when running 3D MARK200 1SE and using 1024*768 32-bit color, and can reach nearly1when using 640*480 16-bit color.

This achievement is close to the level of Radium 9600 desktop version, which means that this achievement is close to the mainstream 3D level of desktop computers, which can fully meet the demanding 3D games at present, which is very good news for those game enthusiasts.
In addition to a powerful graphics chip, you need a good display screen to show it. It is hard to imagine how a radium 9000 chip can be loaded on a machine with an 800*600 display screen.

H500 adopts a high-brightness display screen with a resolution as high as 1400* 1050. The brightness of this monitor is very uniform, and the color performance is very similar to that of Japanese brands. Unlike European and American notebook brands, it is a high-quality notebook display. Compared with the screen of JOYBOOK 8000 wide-screen high-brightness notebook in BenQ around me, it is not inferior at all, but the brightness performance is not as good as JOYBOOK 8000, but it is quite difficult for a notebook that is not fully positioned for home use. At present, it is rare for domestic manufacturers to use such high-quality and high-resolution LCD. Generally speaking, the display of H500 is almost perfect, except that some domestic widescreen manufacturers will use high-quality LCD, but this is the first time I have seen such a perfect display system on a notebook computer with a common proportion.
The perfection of the display system can only be regarded as a matter of face. If we go deep into this laptop, we will find other advantages. H500 uses a hyper-threading processor with a main frequency of 3.06GHz, and its processing performance is definitely not comparable to that of ordinary laptop processors.

A few days ago, I was shocked by the processing performance of Sony GRU7CP2.6GHz. Hehe, now it seems that my super notebook computer has also become this 3.06GHz product.

We can clearly see two processors in the hardware device manager, which is the most attractive place of this notebook computer. There is no doubt that the use of desktop processors can reduce the overall cost and improve the performance of notebook computers. During the operation of WIN XP, this processor works very well with 5 12MB DDR memory, and there is no procrastination at all, especially when multiple windows are opened at the same time to run multitasking programs. At the same time, opening WORD, PHOTOSHOP, EXCEL, IE, QQ and other program systems will not become very slow, which is the benefit brought by the high-speed processing platform.
However, high-frequency processors will also bring some negative effects, such as high fever, which is the first problem to be considered when using high-speed processing platforms. At present, only IBM G40 and Sony GRU7CP use VHF processors for notebook products, of which GRU7CP uses 2.6G processors at the highest and G40 uses 2.4G processors at the highest. Few domestic manufacturers dare to use such high-frequency processors, and only NEC has them abroad. (Please click for details) But H500 did it, and it was a great success.
Compared with G40, H500 wins by using discrete graphics card, and wins with better screen and lower price compared with GRU7CP. So, if you want to buy a cheap desktop substitute, don't consider the H500. After all, you can get such a strong product at such a low price, and you can completely ignore the shortcomings of rough workmanship. I believe that users who buy this machine will not carry it on their backs every day, and at most they will use it occasionally.
This kind of notebook computer with desktop computer will generate a lot of heat during use, the main heat is radiated from the cooling fan, and the bottom near the processor is also a concentrated source of heat. In addition to these places, the keyboard is also a big radiator, similar to the keyboard convection heat dissipation method adopted by some European and American manufacturers. But after all, the desktop processor is used, and the heat is considerable.
If the heat only radiates from the bottom and the cooling fan, then this product is not suitable for legs at most, but if the heat radiates from the keyboard, the comfort will be greatly reduced, especially for sweaty friends. In addition to keyboard heat dissipation, the hand rest is also very hot. After the author used 10 hours continuously (because of the desktop processor, the CPU can't be used down, so as long as it is turned on, the heat dissipation is always the maximum), the hand rest began to become very hot, and it has gradually approached the temperature of the keyboard. Such a large heat dissipation is beyond the author's imagination, so I have been worried about the stability of this product. No user wants a blue screen or exposure during use.
Therefore, the author conducted an almost destructive test on H500, and ran the DEMO of 3D MARK2003 continuously for one night, with the highest picture quality and without stopping. After about 12 hours (I was sweating like a pig), the machine was not unstable except for fever, and all programs were running normally. And in the process of running, there is no error, blue screen and automatic restart, which makes the author tongue-tied. I always guessed that he would be unstable. Before I ran, I was still hesitant to do such a test, because I was worried that the CPU would burn out. I have never been exposed to such high-frequency notebook products. Fortunately, there is no instability in this process, and stability is trustworthy. However, some people have the impulse to take a look at the cooling system of this notebook.
Just do it, pick up the screwdriver and remove the notebook (in fact, this notebook is very easy to remove, just remove a few screws on the back to remove the bottom change, probably to facilitate the design idea of upgrading).

As you can see, after removing the backplane, the first thing you see is two long CPU heat pipes.

And a huge fan. In this part, there are two memory expansion slots and hard disk slots, which surprised me again. This notebook computer uses a standard desktop memory module with a maximum expansion capacity of 1024MB. If the SO-DIMM slot is used compared with the basic standard, it is estimated that it can save a lot of internal space and reduce heat (less memory particles and less heat).

The author considers Fang Zhengzhi, so the design is based on the cost factor. It is also possible that the fuselage space is very wide, and the standard desktop memory slot can be placed in the H500 without compressing other components. Whether this design is like this is not judged. But at least one thing, such a design is extremely rare in notebook computers.
You can easily take out the hard disk and upgrade it by unscrewing the screw that fixes the hard disk. Fortunately, the hard disk didn't surprise me and didn't use desktop components. Hehe, this is a notebook product with IBM number IC25N.

Using liquid bearing technology, it has low noise and good performance, and has a good reputation among notebook enthusiasts. However, one thing surprised the author. H500, which requires high performance, actually uses a product with only 4200 rpm, which seriously affects the performance of this notebook. Although the mainstream notebooks are equipped with 4200 rpm notebook hard disks at present, there is nothing surprising, but what is really surprising is those products that use 5400 rpm. But on the H500, it is just the opposite, because the processing performance of this product is too powerful. There is no doubt that hard disk has become the primary component that affects performance. Just like a Centrino notebook with a 1.8-inch hard disk, the H500 hard disk system makes me very disappointed. Fortunately, the memory expansion slot is designed as 12.5MM, which can be easily upgraded to various high-speed hard disks, including the 48G IBM high-speed hard disk. 12.5MM is a little compensation. If users who have extreme requirements on performance buy it, it is strongly recommended to directly upgrade the hard disk to a high-speed product with 5400 rpm, so that the H500 can play a better role. If you have money, you should buy a 78G IBM high-speed hard disk.
Let's take a closer look at the heat dissipation function of this product. First, let's take a look at the cooling fan used in H500.

Remove the fan and you can see the heat sink made of pure copper.

This radiator is connected to the radiator pipe, only the radiator pipe is in direct contact with the CPU core, and the heat is brought to the radiator in a large area through the internal liquid pipe. This radiator has a radiator-like appearance, which can effectively increase the contact area between the radiator and the air to increase the heat dissipation effect, which is the first guarantee for the stability of this notebook. There is another point that is very distinctive. Different from ordinary notebooks, H500 does not adopt the traditional notebook cooling mode with bottom air inlet and side air outlet, but adopts a brand-new vertical cooling mode (this term was invented by the author, please take a look at it with me if you have a notebook).
The general way of heat dissipation is that wind enters from the bottom, and an efficient fan introduces the wind from the outside of the fuselage to the heat sink directly, and then dissipates the wind from the side or the air outlet behind the fuselage through the inclined plane. This cooling method is a common way. However, there is a problem of efficacy loss. Because the inclined plane allows the wind to blow out, there is a problem of air loss. So which heat dissipation method is better, which is what I call vertical heat dissipation. Vertical heat dissipation means introducing wind from the bottom and blowing it out directly from the top. Of course, some side air outlets can also be designed to assist heat dissipation. H500 adopts such a cooling system, so it can achieve such a stable operation effect.
So why don't ordinary notebooks use vertical cooling system? The answer is simple. Generally, the internal design of notebook fuselage is very compact. Fans are usually designed to hold the motherboard or stereo. It is impossible to take out a hole above the fan to dissipate heat. However, the H500, with its wide fuselage, takes advantage of its own advantages. This innovative way (let's put it this way for the time being) has brought exceptional stability to H500. Although there are too many heat dissipation points, all the heat is effectively radiated outside the fuselage, which is undoubtedly successful.
These parts are basically on the left. Let's continue to tear down the right one. The fun is yet to come. After removing the right cover, we can only see the empty CD-ROM drive position.

Below is a large aluminum radiator, which is covered with many prickly protrusions, which means that if you take the whole chassis apart, you can see two large radiators.

Hehe, this picture is really spectacular. Of course, this is also the effort made by H500 to dissipate heat. What is this radiator for? First sell it, disassemble the radiator, and then unscrew all the screws on it, so you can easily remove the radiator. At this time, you can easily see what is under this big radiator.

Hehe, this is the south bridge chip of ATI MOBILITY RADEONTM 9000 graphics card module and chipset. Of course, these two places are also the two major heat dissipation of this notebook besides CPU. How to effectively dissipate heat without using high-efficiency copper fins? First of all, the graphics card core and memory particles are stuck with thick heat dissipation silicon pads. This kind of silicon pad can quickly introduce heat into the heat dissipation block, and then the heat is dissipated by the barbed heat sink. The reason for using the thorn heat sink is the same as that of the CPU heat sink, which effectively increases the heat dissipation area. In addition to the silicon pad, a small fan is used to blow heat in all directions. The most important thing is the chassis of the fuselage. The reason for this is that the chassis is made of metal paste, which can also easily dissipate heat from the fuselage. That is to say, the H500 adopts the auxiliary heat dissipation method of the chassis, which is also the reason why the bottom of the H500 heats up. Hehe, the original heat shows that heat is being emitted. At this point, the author was completely impressed by H500' s efficient cooling system.

In addition to the advantages mentioned above, H500 has many minor defects, such as soft lower part of the hand rest, slightly insufficient supporting force, loud operation noise, loose keyboard, loud knocking noise and so on. However, considering that this is an efficient laptop, these minor problems can be tolerated or ignored.
After a long period of local disassembly and use, the author deeply feels that the domestic notebook is also making continuous progress, and the speed of progress has far exceeded everyone's expectations. Starting from H500, the author is also pleased with domestic products. After a long period of stagnation, some surprises finally appeared. I believe that in the near future, domestic brands will make Chinese people more proud, but at present, the primary problem is to improve some small details and problems and improve the comfort of machine use. Once these minor problems are solved,
