Dell’s Latitude business notebook, although the world’s largest-selling business notebooks, but has been in the country such as the ThinkPad is not known, but rarely referred to its weight and the magnesium alloy casing of these characteristics. However, the Dell Latitude in the domestic sales and can not be overlooked people, this time, we finally have access to the most representative of Dell laptop, Latitude D620, who from this product, we will have the opportunity to learn how to pilot commercial notebook DellThe real reason the market.

Dell D620 main configuration is as follows: 

Processor: Intel Dual Core T2400, clocked at 1.83GHz;
Memory: 1G 533MHz DDR2;
Graphics: Intel GMA 950 integrated graphics chip;
Hard Disk: 5400 80G;
Screen: 14.1 inch WXGA;
CD-ROM: 24X CDRW / DVD Combo;
Wireless: Wireless 1490 802.11 a / g;
System: Windows XP Pro;
Other: Built-in Bluetooth

Dell D620 laptop as a business does not play tricks on in appearance, still the past, classic design, Logo and no change.

Functional performance – moving in 

Functional performance 

Dell Latitude D620 has excellent mobility, performance and move on to achieve the perfect balance. This balance is then set up the ThinkPad T series, and its main features include the role of the weight of 2.3Kg, 14-inch screen, the mainstream processor and graphics card, Dell Latitude D620 full continuation of this character, and play to new heights. Remove the drive in when Dell D620 re-release alone was 2.21Kg, and in the installed optical drive, its weight is 2.45Kg.

We got a classic business ThinkPad T43, contrast, D620 thickness is worse than the T43, but can see the D620′s performance more broadly.

The D620 is still using a full-size keyboard design, and inherited the D610 style buttons on the T43 to feel more flexible, while the middle of the keyboard, we can see the pointing stick, touchpad also set up a fingerprint region.

Interface, the D620 is also available, left, anti-theft lock, audio interfaces, infrared, WiFIPCMCIA, Smart Card:

Rear interface more, the distribution of the RJ45, RJ11, 2 x USB, serial, VGA, power adapter, vents:

Lower right side of the interface, in addition to CD-ROM (replaceable), but also equipped with two USB ports for cascading style design, a little failure:

Front of the D620 is very simple, the middle speaker, Right place, we can see the  Dell Latitude d620 battery:

D620 at the bottom of the modular design, docking well inherit down.

Dell D620 as a new generation of business notebooks, with many places of natural success.

Connectivity, D620 offers a variety of options: Wi-Fi, rDA, Bluetooth, WWLAN, compared to D610, D620 increased WWLAN communication connection.

Dell D620 battery is very user-friendly, with a battery status display:

The choice of the Dell LATITUDE D620 Battery, D620 provides 4-pin, 6-cell and 9 cell in three sizes: 

Life on the D620 6-cell lithium battery life can be 4 hours and 20 minutes maximum, which is a very rare discrete graphics notebook. Of course, D620 also can be used with 9-cell Dell Latitude d620 battery, this notebook will highlight one of the front end, and life will be more satisfactory.

With experience – pointing in 

The keyboard each key fixation, without disturbing each other, can do this keyboard should be said to be more ideal. However, the noise is slightly larger keyboard, it should be said, compared with the ThinkPad T Series, or an ordinary point. However, the pointing stick and touchpad pointing devices, have no less double, and the little blue dot using the movement of skilled future use can greatly improve the efficiency of the control mouse.

Laptop dual pointing devices 

TrackPoint with perfect results

Heat, since the bottom with a full magnesium alloy material, so the cooling efficiency, and in addition to the fan, but Dell is still left of the keyboard to open a skylight, to effectively improve the thermal efficiency. However, sometimes the fan noise or can be perceived, after all, are running at full speed processor and graphics card, then a lot of heat need to be distributed.

Window across the bottom of the notebook cooling 

Warranty terms, comprehensive protection for three years satisfactory service. Dell can provide such a commitment, but also the physical protection with superior notebook inseparable. And accessories, the Dell XP Professional pre-installed models with the system CD, which is the user’s investment is a form of protection. After all, users pay for the expensive operating system will not only want to see a system recovery disk.

Overall, the Dell Latitude D620 is very focused on protecting the user’s investment, which is a little bit of action from both can be seen. Moreover, its shape and compared to the previous generation, has been greatly improved, the cool bottom of the notebook is useful when holding the handle. Therefore, I give it 8 minutes to play, deficiencies are more old-fashioned appearance of color, and internal too simple, there is no individuality and style it a serious business.

Summary statement of advantages and disadvantages 

Dell Latitude D620 notebook is an excellent business notebook, and equally suitable for home use. Some people think that with the ThinkPad T series there is a certain gap, specifically, in the personal vanity or the satisfaction of taste, there is a gap in the country, but the efficiency in the ability to complete work on the Dell Latitude D620 favorably. Objectively speaking, the new ThinkPad Z series widescreen notebook Dell Latitude D620 is not the opponent, but compared to the T60, D620 has the advantage of price and widescreen. I appreciate that Dell is that it would be the integration of advanced technology in a notebook, but the price was more makes it easier to accept.In addition to configuration, Dell’s advanced design concepts and detailed on the D620 was the perfect interpretation.

The overall design of the light so that users feel impressed 

Advantage 

Graphics card with the perfect balance of performance after
The new design, 14 widescreen ideal size and weight
Magnesium aluminum alloy, firm and rich texture
Reassuring service and reflects the overall sense of security
Reasonable prices, and free custom purchase

Disadvantage

Overall color is more serious, the lack of individual character

(In the evaluation, it is difficult enough to find the D620, but I still have some hope: I hope that six months after the Dell Latitude D600 series, to adopt the 64-bit dual-core processors, with NAND flash memory pre-fetch, and 802.11 n wireless LAN, and optional dual hard drive support for RAID O, and pre-installed Windows Vista operating system, once the pinnacle of mobile computing push, because every time the first time the new technology to the notebook, and maintain a reasonable price The compatibility and stability, have Dell Latitude series notebook figure.)

China is the world’s largest production and consumption of battery power, with the mobile phone, notebook, computer, especially the rapid development of new energy automotive industry, the future of this industry out of the used batteries will be more than a billion in 3000-5000, so in the used batteries Recycling is not only national environmental policies, but also in line with the national low-carbon economy, circular economy industrial policies. These are pictures of our products, the biggest feature of these products is that all, including BYD, including from the world’s leading battery manufacturing classes, and we sell more of these products and all of these manufacturing companies, this used to achieve orientation of the battery to the battery materials cycle, this cycle will be directed from the battery manufacturing, consumer to recycle the organic link of the entire flow of the integration, which is a marketing strategy for our unique, because waste come from, where materials go, We procurement market, where sales market to where it is.

According to this model, our business has developed from a small battery to the power of longitudinal cell cycle, lateral cell phones and laptops to electric cars carrier to do the next cycle.

In the fair period, Wang Yang, secretary also specially concerned about our recycling of used batteries Bump cycle power technology demonstration center, and hope we can become the Pearl River Delta of Guangdong Province and even the entire electric vehicle industry, supporting businesses, Bump technology cycle with the foundation, also has This expertise.

Not many people own our company, college or technical and management personnel directly involved in only 99 individuals, only 3 individuals, Dr., in addition to a professional manager, own 16 patents, 11 are invention patents. This time we have a preliminary plan to the capital market, within the next 3-5 years, with 300 million yuan power cycle the battery industry, the development of 600 million yuan 5-cell vehicle development cycle industry, of course, will put the industry in Foshan to conducted in preparation for the cashier within 20% stake, in the past three years of financial data. we have is not very high because there is no entity operating in Foshan, net profit from the enterprise and other relevant financial data, business growth, profitability and safety is good . Next five years, sales are expected to be exceeded 10 million, net profit in a million or so.

This process is accompanied by a number of business-type risk factors, because our products are associated with the non-ferrous metals, interest rates and exchange rates have some impact on us, in addition to reverse product orientation product is designed to do, waste come from, raw materials from Where, we have completely different with the raw ore, the process is a typical technology-intensive and capital-intensive business model, this business model is very unique. Another is the cash we have established across the country and the system of public recycling system of used batteries, the public collection system for all operating expenses are business themselves, so from a business point of view, it would be one of the risk.

We made this industry very good taste, but also scientific and technological strength, but also bear social responsibility. This place has some of our business VCR, please look.

Hope this little story that touched you, my lecture finished.

Moderator: Thank you, I always excellent introduction, see Which private venture capital organizations have a question for the guest.

Guest: I always Hello, Thank you for your lecture, I have a problem here, you mentioned the future development of the company strategy is to invest 5-6 billion in the battery carrier of this one, because I am not very familiar with this industry, please tell us about how fast the other business model of the market size is what kind of situation?

Yu Haijun: the equivalent of an electronic medium we are using laptops, and mobile phones used by each person, we have to open the next electric car, this is the battery carrier, the carrier of these batteries is very important to the future, growth in our industry which space. If we do not make the battery carrier recovery, then the battery to be uncollectible, it is difficult to establish a complete recycling system, we now establish the recycling system on the downstream, upstream is the battery manufacturer, scrap batteries, defective battery, battery recall , 70% lower in the hands of the people, but the recovery is difficult, people do not know the battery category, invested in the second step to know where there is environmental awareness, to establish a common battery of upstream and downstream distribution channels, carriers also need to recover again, but high-value carrier, in addition to non-ferrous metals, we need to make directional loop material of electric vehicles is critical pool materials, separator, electrolyte, but we do directional cycle can be restored to product quality, the first is energy conservation, the second we able to use high-tech industry which, so to do this kind of strategic planning is consistent with our business, also in line with the national environmental policy.

Guest: Hello I always, I am from the East VC, the first you want to introduce the battery industry is certainly a more sunrise industries, the future is very bright. I understand that the key to your heart, in the battery recycling channels, as I see commercials say, you have established the pattern of small hand in your big hand, as far as I know people are using batteries, small channels into the recovery, this one can not recover more number of batteries, for the future development of your enterprise into a virtuous cycle is very important, I think this piece of you more ideas.

The second cost recovery, probably accounting for the battery you are now the final share?

Now you reverse engineer the third piece of the market competitor?

Yu Haijun: Let me answer the first recycling system is very important, the first people in the hands of used batteries is very difficult indeed now recycling back, but now our recycling batteries, for example, more than 99% of the production process are battery factory is this part of the upstream and downstream can not do, from our business perspective, from the government perspective, from the entire social development considerations must be done, because of the need to cycle, not lost it, the landfill to can solve the problem.

The second issue of costs down and then we go into the details.

The third is the world’s original reverse design, worldwide recycling of used batteries do have a business in Belgium, Japan has a business, China is only us, but we are really the level of used batteries to achieve this quality battery materials business , there are many companies recycle, recycle batteries traders, self-employed are also very much but the recovery after the classification of borrowing to sell, do not rotate, we are really doing product design orientation and then directed the business cycle, this is our characteristics.

Types of Batteries

Secondary batteries-

Secondary batteries are those batteries which may be recharged many times. The number of discharge/charge cycles the battery can withstand depends on the type and size of battery and on operating condition. Numbers of cycle is varied from fewer than hundred to many thousand among them are lead-acid, nickel-iron rechargeable alkaline etc.

Batteries are also classified as dry and wet batteries-

Dry batteries-a dry battery refers to the cell that can be operated in any position without electrolyte leakage. Wet battery-these batteries have vents to allow gases generated during charge or discharge to escape. The most common wet batteries are lead-acid battery; these batteries must be operated in upright position.

Ratings of the Batteries

Batteries capacity refers to the amount of energy the battery can provide under specified condition. The conditions so specified are temperature, current drain, discharge schedule (m/hr), and final output voltage when completely discharged. The amount of energy available varies widely as these specific condition changes. The capacity of a battery is expressed in ampere-hour

Safety Concerns while Using a Battery

As per the discussion, we conclude that, if the batteries are not properly handled, they can be dangerous. The acid used in the electrolytes can cause skin burn and it is extremely harmful to the eyes. The gases released from charging battery are explosive.

Different Types of Batteries – Primary Batteries

Primary batteries: Primary batteries are also called as disposable batteries. These batteries are designed for using only once and then those batteries are exhausted and cannot be used again. Those batteries are use and through batteries. These batteries cannot be rechargeable because the electrochemical reactions take place only once and these cannot be reversible. The reactions are irreversible reactions. The primary batteries also called as dry cells because the electrolyte that is used in these batteries is a paste like material and not a liquid. Primary batteries are used in the devices which have very less current. Primary batteries will have more initial voltage and these provides good capacity. Carbon or zinc batteries are of less cost. Primary batteries mainly used in torches, toys and radios etc.

Different Types of Batteries – Secondary Batteries

Secondary batteries: Secondary batteries are also called as rechargeable batteries. These batteries can be used several times. After the batteries are discharged they can be recharged again.  These batteries can be used many years. The reactions that take place inside the batteries are reversible which means that in the secondary batteries it is possible to convert electrical energy into chemical energy by charging these batteries. It is essential to charge these batteries before using it. Re-chargers are available in the market. Acid or lead batteries are the examples of these secondary batteries.
