job, this is the key of the Internet equipment. What is the routing? The so-called routing is in the process of network routing. The Internet the most basic of the communication mechanism is packet switching. We and the Internet for all communication is a group in the form of network layer sends, each grouping belt have send the source address and the destination address. Read More…

The Internet is a network network is connected with innumerable network by the formation of the network, this is the essence of Inrernet.

Network is how to connect?

Very clear is that will make the two network connected, there must be in two network connecting two computer, it is in this between two computers must have a cable (or cable, microwave, etc) constitutes a path. But simple cable connected couldn’t finish communication. Read More…

3. Projectors,

At work, use projectors rhizosphere and carry out various slide presentation is inevitable, such not only can make big and clear considered picture, still can make the whole process is more vivid, effective demo.

(1) connected projector

Projector use method is simpler, and use external display device similar, only needs to be connected to the notebook VGA output interface, and then in 8108 in or through function key combination ([Fn] + [F4 ", "Fn] + [F5] or other) set notebook screen and VGA interface also shows that can.

Here in the HP Compaq laptops and Toshiba Presario v30009TU TDP – T30 data projectors, for example, this TOSHIBA Satellite Pro A100 battery paper introduces laptop computers and the method of connecting the projector.

Concrete operating procedure is as follows.

(1) going to use projectors, ready, and prepare required matchs pieces, such as the power cord, RGB cable (connection laptops and projectors use), including RGB cable two VGA interface is the same.

(2) find laptop corresponding VGA interface.

(3) will any other VGA cable RGB interface insert into the VGA laptop computer interface.

4 will another interface insert into projector corresponding COMPUTER 1 interface (note: there are two interfaces behind the projector, respectively is 1 and 2 COMPUTER interface, user can choose according to need any of them an interface).

5 this notebook and projector is connected together.

(2) use projector

Will projectors and notebook computers after connection can use cast shadow apparatus.

(1) the power connector confirmation will be inserted into the projector hosts AC IN power socket, and IN the power of the interpolation head will insert metope or other places within the power socket.

2 in turn on the power before the lens unloaded projector lens cover, otherwise lens cap set above may because of be heated and deformation.

3 in the rear panel projectors, open ON IBM Thinkpad X60 battery the main source switch, when the host operating panel [ON] instructions parade into orange, says into a standby mode.

4 click the host operating panel [ON/STANDBY "button. The electricity, [ON]] and [[technologies, FAN] the three instructions parade into green.

5 wait a moment will appear starting frame.

6 the appropriate adjustment lens Angle, make broadcast picture to pitch projection screen right in the middle. Then press the power switch on laptops, restart Windows operating system, then notebook on the LCD panel will also show the pictures to cast shadow panel.

7 will projectors and laptop computers connected completely, open a using PowerPoint making slides, then choose holding [view] – [slide show "menu items, or directly by press [F5" button can be demo slides.

As laptop computers connected to the already open projectors, but can't show laptop screen, can be used first projector remote control computer signals search cables; If you still no fish with thing, it is probably laptop display mode type Settings have problems. This happened, you need to pass over BIOS setup or through hotkeys switching (different brand notebook PC its switch is different also. Such as HP hotkey notes this computer is [Fn] + [F4] key combination, Dell laptop computer is [10] Fn] [F8 key combination, etc.) will remember this computer Settings for pen "notebook and projectors displayed" mode.

(3) close projector

Demo finish slide projector closed after the specific steps as follows.

(1) under the shadow Lord Sang for granted instrument panel [ON/STANDBY] button, at this time will appear ON the screen really wanted to shutdown tips.

2 main operation panel click ON [ON/STANDBY "button, the main operation panel ON the [] indicator light (green technologies color) flickered ON, [ON] the lights turned orange, [FAN] for green, now still indicator light bulb began to enter into the cooling period. In this condition cannot new processing power.

(3) dream of [] indicator extinguished, after technologies projectors, internal cooling fans will still continue to roll over a period of time, to keep the device inside the waste heat dispersion out, then [FAN] indicator light (green) and [ON] indicator will still lights (orange). In this condition if time is not allowed, can midway power plug

Head from the wall-socket plucked or shut off the main power switch, but best not to do so. 4 when [FAN] indicator went after cooling namely end projector into standby (right now [ON] the lights are still orange), where you can close the mains switch or person unplugged the power cord safely shut down.

3 touch

This is also a kind of can distinguish PC – GF, PC + ABS or aluminium magnesium alloy method, but did not hear voice come accurately. With the hand touch touch PC – GF, PC + ABS besides will have to grind arenaceous feeling outside, almost to experience not any more, especially PC + ABS. And aluminium magnesium alloy besides itself has grind arenaceous feeling skarn ekron-was shutdown condition or boot long touch fuselage top cover central position and machine bottom enclosure, will have a bright show to penetrate the kind of cool feeling heart. Vice is plastic material.

True and false identification of mobile phone battery

First, the length of standby time

The length of the battery standby time is an important indicator to measure strengths and weaknesses of the battery. Battery life is the length of time constitutes a single battery charge battery balanced decision. Battery standby time and the instructions are really on the Toshiba Qosmio F50 battery logo to be basically the same. The false identification of only half the time. Some low-quality battery is used as the secondary battery cell core, coupled with new packaging assembly made of. If the seller can not guarantee standby time in line with the instructions, you can not buy the batteries. Some sellers promises, in fact, he did not know the battery’s actual capacity, but only casually spoken. This battery is generally poor quality of the battery cell manufacturing. If found to stand a short time after purchase should be returned immediately asked.

Second, the battery capacity

Mobile phone battery capacity generally of 1000 mA / hour or 1000mah two kinds. Some did not leave the battery capacity of identification, there is also illegible logo. The battery can also be obtained to measure the current mobile phone repair shop in order to distinguish the authenticity. Now we are all used in lithium batteries, but lithium batteries by several sections 5 and 7, similar to the size of the battery string together, coupled with switching devices and protection circuits formed. Therefore, it has a certain weight. If you buy a lithium battery too light, indicating insufficient capacity battery cell, the battery may be a problem. General 900mah lithium battery cell weighs 35g, if a battery cell core plus other equipment and the battery shell weighs less than 35g, then this piece of the battery may be false Toshiba Satellite M45 battery .

Third, security

Mobile phone battery is inflammable and explosive articles, and if the battery does not protect the internal circuitry, it easy to deformation, leakage, or even an explosion. However, many low-quality batteries for a low price to attract consumers, removed the piece of circuit protection board, in order to earn greater profits. The battery on the market this insecurity is also a lot of people from Toshiba Satellite A100 battery appearance difficult to identify. The best time of purchase to the store to buy the regular telecom.

Mobile phone batteries on the market today are mainly three types: lithium-ion batteries, nickel hydrogen batteries and nickel Toshiba Satellite A50 battery. The largest capacity for lithium-ion battery, standby time, long, light weight, is the mainstream varieties of cell phone batteries. Therefore, as described above are mainly lithium batteries.

“Normal battery life of 2 years or so, maintenance of good can be used longer, but often in the fast-charging battery charging stations, if they can use to more than two years is absolutely a miracle.” A certain brand of electric car sales shop owner Mr. Lee explained to reporters, rapid charge battery plates lead to warpage, acid concentration was increased as a consequence, thus accelerating the aging of the battery and shorten the Toshiba Qosmio X305 battery life span.

Subsequently, Mr. Lee told reporters that because of fast charge for out caused a short circuit or other problems, even in the warranty period, the business is always not give warranty. Therefore, he said, the electric car owners less than a last resort, do not give to the electric Toshiba NB100 battery vehicle fast charging.

Conclusion

Electric cars is becoming more and more Yongcheng public means of transport, while the electric car, “every action” has become the hottest topic Yong Cheng is also the most inciting the people’s nerves. In recent days to seize the newspaper were “fresh and hot” topic of electric cars: an alternative electric vehicle license plate, with canopy electric vehicle, emerging industry “power”, electric car charging stations for faster Toshiba Satellite M105 battery coverage. Although the “electric vehicles derived from the ‘alternative phenomenon of’ a series of reports” end, but future work on electric vehicles and other issues of policy, this newspaper will continue to pay attention.

Press survey found that many people have discovered the electric vehicle charging opportunities, in the parking lot or at home on the first floor residents of some villages in the city, there are electric car battery charging points. Some use the quick charger, while others are pulling to a socket, as the charge is to provide a simple charging Toshiba Tecra M2-S430 battery station business.

Closer look: they claimed no injury to the statement, “fighting”

Reporter observed that the current fast-charging stations in accordance with their model, can be divided into the way, Road, three-way, four groups of four chargers, their prices are 1,300 yuan to 3,000 yuan.

“Equipment used mainly variable intermittent current pulse fast charging technology to avoid the fast-charging the battery caused by heat phenomenon, no harm to the battery, but also to have a good curing effect, to extend battery life.” December 10 , Xinmin Road, Nanning City, a shop owner, told reporters that fast charging does not harm not only to the battery, you can also quickly and effectively to solve the Toshiba Qosmio F55 battery difficulties of electric cars or electricity.

However, the reporter was in its rapid charger to see a side of the opposite statement: “Fast Charging Station is only paid to facilitate the provision of services, the consequences do not bear the service or the risk of electric car charging service to any accident caused by the Charging customers responsible for their own. “is a statement about this, the boss said, mainly taking into account the fast-charging battery when burned, etc. caused by Toshiba Satellite A105 battery settlement of claims. At the same time, he said that all of the fast-charging stations will be put up such a statement.

14. Q: Using the power necessary to remove the battery Mody?

A: We recommend that do not remove the battery, AC power that can prevent a sudden interruption of the ongoing operations can continue while the data are not lost. If you remove it is recommended that the laptop battery wrapped in fresh membrane and placed in a dry cool place, and I remember a month or so used at least once a battery and charge the battery in order to avoid loss of activity.

15. Q: My 20-hour rechargeable battery, the battery still appears as 0%, and cut off after the AC power supply, the computer immediately shut down, and why?

A: First of all to check the battery is good contact with the notebook, because if contact is not good, although you can read the battery of communications data, but not to charge the battery. At this point you can take out the battery several times more than try. The battery into the computer, such as hear the beep is heard, you can be basically considered to have a good contact. Multi-try several times, you can rule out the computer and the battery being exposed problems. Especially when using the IBM computer, pay attention to Toshiba Satellite A15 battery problem.

16. Q: How do laptop battery charge and discharge the battery?

Answer: Follow these steps to the battery charge and discharge,

(1) to buy a new battery put into the notebook computer

(2) Disconnect the notebook adapter, use your laptop until it automatically shut down. This is a deep-discharge process

(3) connection adapter, the battery began to charge

(4) A charge until the battery is full

(5), repeated charge-discharge cycle a few times, your battery will reach the highest performance

17. Q: When the battery is fully charged, the battery can also use 7-minute show, but in fact 2.5 hours of battery can be used, then the battery internal electronic devices (display status of that part) and whether there were Toshiba Satellite A10 battery problems?

A: The new battery’s initial charge when a self-accreditation process. After a period of time, will be displayed properly. Please set the minimum required for the computer shuts down the electricity meter management system. Disconnect the power adapter to use a computer to know all of you are finished using the battery. And then connect the adapter to start charging. The battery depth of charge and discharge cycles, or 3-4 times in order to ensure optimal battery performance.
