Would you buy a second-hand laptop ?

Everyone knows that the IT environment, technology is advancing a huge boost. After a while your purchase, and after the introduction can be felt already, it appears that a new machine with all its intricacies was already a new model coming in the legs. All PC users will not have to work the latest technology to do a test when financial investment to be profitable. Used, but fully restored when the computer is the right choice.

The entrepreneur can venture life cycle may have a situation where it is not possible or even makes sense to buy new computers to all its employees, or commit to new computers for long time, 2-4 year lease. In such situations it is reasonable to consider used, but refurbished computer purchase.

Here are five things that you need to know when considering a used Vostro 3400 battery :

1. Of used and refurbished computer difference

Used a computer has had one or more users in the past, and each have left their mark on the machine. Used machines are often sold in such a condition as it is currently trading, its possible flaws and faults.

Used, but refurbished Dell inspiron 1570 battery is the safest option. Many companies hire a very durable and maintenance-held computers, for example, 2-3 years. Computer users are aware of the daily also, that the machines they are "just a loan", so they also deal with machines hellakatisesti. Lease after the machines returned to the manufacturer or seller, which is to restore, check and test the machines completely. The machine memory is erased and the previous software has been removed. Instead uploaded a new owner for just about everyone, and ordered the necessary software.

2. Ensure Quality

Used computer is sold "as is" and the buyer has the opportunity to palauttaa Kunnostettu Dell inspiron 1764 battery
has been fully refurbished, so it is, and its activity is almost as good as new.

3. Make sure warranty

Several used laptops for trade deals appear attractive. The buyer may not, however, peace of mind, because the USED the device is missing the manufacturer's or distributor's warranty. The buyer can not be sure without a guarantee on the quality and reliability of your computer. Refurbished laptops are always either the manufacturer or supplier of processing services warranty.

4. Insist on value for money

Refurbished computers are reliable, because of their performance, and actual values are the same functionality as the new computers. Refurbished equipment is also responsible for the new warranty. Refurbished unit price is only part of the Vostro 3300 battery became a tool of the price.

5. Extending the lifetime of the computer is ecologically

Conscious supplier of the device takes care of client's IT environment, equipment recycling, data destruction, and its best to continue the life cycle of the device through the rehabilitation of disused equipment.

A laptop Suit for You

Motherboard

The producer seeks to reduce the size, weight laptop, so that each model is a special motherboard. Therefore, the opportunity to replace it with a firmware update does not exist. The most important thing to him was an extra seat (or two) to add more memory.

Hard disk drive (HDD) for notebook

Hard disk drive (HDD), such as a Dell Inspiron E1405 battery and the desktop is the largest airline information.

What is the amount of hard drive to buy a laptop depends on what tasks to it. Based on 2006 years model, you can buy a laptop for the amount of Winchester 40-200 GB. Of course, depending on the hard disk parameters are changing, and the cost of the laptop.

Portable Hard Drive has its own peculiarities, which are related to the desire of producers compactness and lower power consumption model. First of all, portable hard disk drives smaller than those of a desktop computer. Second, how to buy a laptop hard drive depends on the Spindle speed. In order to save energy stations for portable computers is the speed is not greater than 5,400 rpm, although the amount is 200 GB. But office work would be better to buy a laptop hard drive 4200 rpm.

The possibility to replace the hard drive more dependent on each model. So before buying a laptop to determine this detail. It is also always the possibility of connecting an external hard drive via a port or PCMCIA Express Card, but this solution is not always nice.

Memory

Minimum amount of RAM the notebook to get 256 MB. Work in the most demanding applications it is desirable that buy a Dell inspiron 15 battery for 512 MB of RAM. As the PC has no memory, the data is sent to your hard drive. And this in turn will reduce speed and increase energy costs. That is why we need more memory, expansion slots, should affect the way how to buy a laptop. In addition, what kind (DDR or DDR2) is used not as an important prerequisite, because tests show that the difference in the speed of their work is meaningless. You can install additional memory, contact a service representative.

Video Card Memory Book

Graphics card notebook does not have a choice. You can already buy a laptop graphics card installed by the manufacturer. Initially, this set was of little significance, because the computers were granted to the device documentation. Now, when users' needs are increased, you can buy a laptop computer and a powerful enough video card the internal memory is 256 MB.

Notebook Sound Card

Sound Card laptop is usually built and has all the standard features that are needed. Built-in AC `97 Audio codec is enough. The notebook can be found often, and built in speakers. They have little power, so if you want better quality sound, you should buy a laptop speakers separately. The important thing is that the sound card's audio output was.

Keyboard and pointing device notebook

Laptop keyboard is slightly different than the standard. In pursuing the density of the keys can have custom sizes and location. In most cases, the letters on the keyboard in full-size, and the rest of the buttons are not only small, but they are different. It is possible, even the beauty of the keys to the Russian letters E, F, W, X, is smaller than the others, because the English keyboard, they do not carry the letters. Therefore, before buying a laptop you should pay attention to the keyboard. And better still try to ponazhimat keys, no amount of permanent work, because many of the key may be in unusual places.

Instead, the Dell GW240 mouse used in other devices. Most of this touchpad - touchpad, running a finger to control the cursor. "Click" can be either a panel or adjacent panel. Mostly you can just buy a laptop trackpad, it has been widely used because of the convenience and reliability. You can also buy a notebook TrackPoint pointing device. It is a small joystick located in the middle of the keyboard. The joystick is responsible for the direction and intensity of depression. TrackPoint is convenient because it does not need to remove your hands on the keyboard. If none of these devices does not feel comfortable, you can purchase a special computer mouse (in some models, it will be time set).

Network interface card, modem, Wi-Fi module for notebook

Communications capabilities are very important for anyone who wants to buy a laptop. Therefore, the current models the current standard modem (V.90/V.92 standard, 56k). Also built-in Ethernet 10/100 Mbps network card. It is becoming increasingly wireless Ethernet (Wi-Fi) standard 802.11 b / g Buy a laptop Wi-Fi module is not a problem, many models are equipped with.

I / O ports on the notebook

Optional connectivity provides laptop I / O ports.

Primarily this is a USB port, through which the possible connection to multiple devices. Therefore, it is hoped that this port is present (one to three). Followed by an infrared (IrDA) and Bluetooth. They are used primarily in connection with mobile devices (mobile phones, PDAs). Better to buy a Dell inspiron b130 battery with Bluetooth, because the data rate that is higher than the infrared. But it all depends on the availability of a Bluetooth or infrared port for devices which are working. Maybe even better to buy a laptop as well as ports.

PCMCIA port, depending on you to combine a variety of devices. Type I add more memory. Type II is used in connection with a modem, fax machine, SCSI cards and other devices. Type III is designed to connect additional hard drives.

Also, if necessary, you can buy a laptop ports for video and photographic equipment (IEEE1394), the normal display (VGA), TV out, audio input / output, and place the memory card (SD, MMC, MS).

Weight, size, laptop case

Approaching the question of what to buy a laptop, do not forget his weight and size. As soon as advice to buy a special laptop bag.

Full-size laptop, which is able to completely replace the desktop PC, but it can weigh 5 kg. Weight of a laptop affects not only the big screen, but the other components. Hard Drive, DVD / CD-ROM drive, the drive may be external.

If you often carry a laptop with them, it is desirable to have more compact model (1-2 kg). But at the same time, if you ever wear out a DVD / CD-ROM drive or an optional hard drive, then consider the entire weight of the laptop.

Material Dell hd438 case, it is also important. It not only protects the laptop from damage (especially in need of protection screen), but also gives it additional weight. The most reliable option would be to buy a laptop case aluminum alloy. But if you really have to buy a laptop plastic casing, it takes a long time, important to treat her tenderly. Decorating the body's skin can be found only in more expensive models of the elite.

This basic information will help you buy a laptop the necessary equipment. Questions related to maintenance and modernization process necessarily in stock. The most important thing is not to make a common mistake - to buy a laptop, choose a prestigious brand. Asus Notebooks companies, Acer, Toshiba, Sony, Dell, HP won a certain popularity in the market, of course, not least because of the quality. But this does not mean that to buy a laptop, Samsung, Fujitsu, Siemens or LG is responsible for quality loss. Among the models of these companies find a decent model will serve for many years.

How to repair a 'smart' laptop battery?

Some basic rules, you must connect the repair of a "smart" battery. If the cells are weak, cell replacement makes economic sense. While nickel-based cells are available Li-ion are not sold on the open market. Most manufacturers only offer in a sealed Dell GW240 with protection circuit. This precaution is understandable when the risk of an explosion and fire, when the cells are mounted in a careless manner. Always replace the pack with the cells of the same chemistry.

During cell replacement, the circuit has many "smart" batteries are alive with a supply voltage. Disconnect the circuit if you can only remove a fraction of a second data, important and make the circuit unusable. To ensure a changing cells, connect a secondary voltage through a 100 ohm resistor before connecting the cells. Fed secondary Remove the power circuit after the voltage needed for new cells.

The open circuit voltage of the replacement cells must be removed within 10% of each. The welding cell is the only reliable way to get reliable service. Look in limiting the heat is transferred to pay the cells during welding. Excessive heat can damage cells.

During storage, each cell has discharged to a charge state of differentiation. This is particularly important for nickel-metal hydride. To ensure proper accountability for all cells without overcharging some, conservation of newly repaired packet payload for approximately 14 hours, then a cycle of loading, unloading and loading. This cycle is also necessary to restore the fuel bar. Lithium lion Dell kd186
can have a normal charging time is approximately 3 hours. The Cadex C7000 Series feature a program that is based on priming automatically.

How to calibrate the "smart" battery

With the commitment and time, there is a tracking error between the chemical battery and the digital sensing circuit. This leads to a loss of precision of the SoC.

Optimal use of "smart" Dell xps m140 battery, if it refers to the precision fuel gauge, and then fully charge a fully discharged at a constant current. In such a case would be the tracking error of less than 1% per cycle. In real life, however, a battery for a few minutes to upload and download may vary greatly. Long storage also contributes to errors because the circuit can not accurately compensate for self discharge. Finally, the true power of the batteries out of sync with the required fuel gauge and a full charge and discharge is "relearn" or calibrate the battery.

What if yourDell Inspiron E1405 battery is not calibrated regularly? Can this type of batteries used in confidence? Most "smart" chargers obey the dictates of the chemical cells rather than electronic circuits. In this case, the battery is completely free, regardless of the setting of fuel level and function normally, but the digital display is affected. If not corrected, the fuel gauge is just a nuisance.

The selection criteria of laptops

The weight, the first purpose of a laptop is to be transported! The weight is a fundamental criterion. Consider the type of travel you plan to do most often (car, public transport, etc. ...). Mobile phones are often more powerful but can be heavy applications you use on the go do not they require an enormous power? It must in any case ask the question and assess your needs. To date, the machines fall into three categories: ultra-portable, transportable and portable conventional.

The lightest laptops are netbooks. These machines are very light but very powerful. They should be selected only when the weight is the most important criteria because they are limited in power and we believe it is better to opt for a more versatile machine if mobility is not your first test.

- Autonomy: again it depends on your needs. You carry your Dell inspiron 1300 battery from one office to another? In this case, autonomy is not necessarily a paramount consideration for you. It is quite another if you plan to use the machine in the train. Consider the opportunity to gain an extra battery if the machine you choose does not have autonomy in accordance with your wishes.

- The size and screen resolution: more screens are larger, they are expensive! Please note that equal-sized, flat screen displays more information than a conventional screen (a flat screen 15 inch is roughly equivalent to a traditional 17-inch screen).

Regarding the resolution, be careful if you enjoy working in low resolutions. Indeed, the technologies used often require work in the maximum resolutions available on laptops (if not, the display is fuzzy). Strange, but true. For information, screen 15.4 "(traditional Dell inspiron b120 battery) have in general a resolution of 1280x800 pixels. The screens 17" allows for resolutions ranging from 900 to 1920 x 1441 x 1200. The 20 "are generally limited to 1680 x 1050.

Wifi or not? If you need to access the Internet on the go, you should opt for a laptop with hardware that allows you to connect to a wi-fi. Either your machine will be directly equipped (including centrino technology) or you'll need to add a specific card (pcmcia wifi card). This option can be useful because the wireless terminals are increasingly present

in stations, airports in some restaurant McDonald, etc ...

Attention to safety if you connect in this way: Choose a password long enough, and properly configure your hardware. Hackers 'wireless' are growing!
Different wireless standards are the slowest to fastest: 802.11b (11 mega bits per second), 802.11g (54 Mbps) and 802.11n (up to 540 mbps). These speeds are theoretical, the actual rates are lower, and varies with the distance the signal must travel, barriers, etc. ..

- Built-in webcam or not? If you use a webcam on a frequent and on the go, that it is integrated into your machine can help you. For if you are against the webcam in one place, it is often better to choose a non-integrated. Indeed, the webcam built into phones are not always of good quality (currently the standard is 1.3 megapixel, check the resolution of the integrated model). More when they are not adjustable, it's really not very practical.

- The choice of processor: The Dell inspiron b130 battery are equipped with the latest generation of multi-core processor ("dual core" or "dual core" There are also quad-core processors (quad core). These processors are processors that have been two or four units of computation (in a very simplistic, one can say they have two processors). We recommend this type of processor if your budget allows, even if not quite yet fully exploited by current software, because they are an essential advantage when several programs are run simultaneously. You can find information about processors here.

If you want the best of the best, choose a Core i7 (a four core with advanced features to save energy).

If you are looking for a used laptop (therefore less powerful, for example office work) you can direct you to individual processors, the Pentium 'M'. These processors sontpeu energy efficient (they are designed for this). To give an idea and allow you to compare a 1.3 GHz Pentium M offers performance equivalent to a Pentium 4 2.4 GHz while the Pentium M 1.6 ghz pentium 4 to approach the 3.06 GHz (more information on performance, click here, complete édude Pentium M on the site X86 secret.

* The term "chipset is a set of 'smart' computer designed to operate together and optimized for it and whose role is to manage the exchange between the main components of the computer (processor, memory, peripherals ... ). The 'chip' is of course fundamental in performance.

A final point to watch: Safety: Laptops are more likely than others to be stolen, or suffer damage due to falls, etc ... You will be even more vigilant about data security, backups and more frequent. In addition, if you think carrying highly confidential data, consider using any encryption software (it is never too careful). You can use gpg is a powerful encryption software and free to choose a Dell kd186 .

To choose a laptop

RAM

In second place characteristics to look in a portable configuration, the processor and RAM are tied. Start with the RAM.

The RAM is what is called the "memory" of the computer, that is to say its working memory. It is in the RAM are stored all the data being processed for access to data in RAM is extremely fast.

Some applications use a lot of RAM. When available memory becomes scarce, the operating system (Windows, Linux ...) fetches the memory elsewhere: for example hard disk (file or partition to "swap"), or a USB stick (technology "ReadyBoost" Windows Vista).

In short, when lack of RAM, the Dell Inspiron E1405 battery will search the memory of much slower media (hard drives, USB key), causing a sharp drop in performance (because of the numerous exchanges between RAM and disk drive / USB key).

Therefore he will have more RAM, a Dell GW240 will have more working memory, the less it will need to use the "swap", it will be more efficient.

*There are some limitations in terms of RAM

These limitations may be related to hardware or operating system related.

Computers have a maximum capacity of RAM supported material, which is sometimes relatively low (eg 2 GB max.) And it is impossible to expand the memory beyond that capacity.

In summary ...

Choose the most RAM possible (this is not what is the most expensive).

Check that the RAM meets the hardware limitations (related to the motherboard of the laptop) and software (Operating System related).

CPU

Most people just look at the processor frequency. It's a bit simplistic.

Architecture

Some processor architectures are specifically designed for laptops (low power consumption, low heat) while others are intended primarily for desktop computers. Of course, by their very nature, the mobile processors are more expensive to produce.

Still, some manufacturers do not hesitate to put processors in a Dell inspiron b130 battery fixed in order to reduce costs. This results in an increase in power consumption, more heat and increased noise from fans (who may also be of poor quality to reduce costs).

We must therefore pay attention to the architecture of the processor and whether they are suitable for laptops. Intel, Centrino is the line which refers to mobile processors. These are high quality with good performance and a low heat.

How many cores?

In the race for power, processor manufacturers have faced a problem: They no longer able to significantly increase the frequency of the processors. By cons, they managed to incorporate several "cores" (processing unit) on the same processor, hence the appearance of processors "multi-core" ("dual-core", "quad-core").

Specifically, having two cores on one processor does not mean that the Dell hd438 will go two times faster than a processor with one heart. This means that the processor with multiple cores can perform more tasks in parallel.

To date, there are very few applications that are optimized to take advantage of parallelization (it is also not always possible to parallelize tasks). With multi-core processor, the computer will go therefore not necessarily faster, however it will be much more responsive (several applications can run simultaneously on different cores), which improves the comfort of Use a non-negligible.

In summary ...

Points to look mainly architecture:

array processor

number of cores

frequency

power consumption

core

Other technical information

There are a lot of this information, for example, Wikipedia (eg with the Intel Core 2), for any type of processor.

How to Cool Down Your Laptop

If overheating laptop, it is possible that more of the internal components can be damaged. If this happens, the system becomes less efficient and consistent results on the parts to be replaced.

You can reduce the risk of overheating after a series of simple tips for cooling is useful. The easiest tip to follow is to ensure that the laptop is placed on a hard surface. Portable cooling systems are designed to operate more efficiently on hard surfaces, such as air can circulate better. If placed on softer surfaces, can be heated very quickly and cause problems.

There is the possibility of investing in coolers to prevent overheating. Premium refrigerators have an air of success by providing the necessary parts, which ensures that remain at the optimum operating temperature. A series of coolers are equipped with fans, while others make use of glass to keep the Dell kd186 cool.

How frequently do you use your laptop has an impact on how quickly it gets too hot. The brightness is a function that can cause the temperature of a Dell inspiron 15 battery to increase if not controlled properly. We must also remain open only the necessary applications to perform tasks. Applications could be opened, the processor is more at work and this results in rapid heating of the components if not properly cooled. Therefore, it is useful to only open the applications you need.

The location you choose to work with your laptop can directly affect how quickly it heats up. Any place should be well ventilated and away from direct sunlight. Lack of ventilation in place to operate the computer will make you work harder and faster they are heated. Basically, make sure there is adequate ventilation to avoid this situation.

If you use certain USB devices to get rid of them from the laptop can also be a great idea. Other external devices connected to your machine, the laptop should work to increase energy and this leads to overheating. The elimination of such things as printers, speech, memory sticks and other things can directly help to moderate the temperature, because there is less stress on the machine.

To use embedded systems to save energy. These systems are designed to reduce Dell Inspiron E1405 battery requirements and thus help reduce the level of heat and moderate the risk of overheating. The power saving mode in most modern laptops will likely help reduce the risk of overheating and save energy which is great for the environment.

In general, there are some basic approaches to cooling a laptop and it is to use a coolant external laptop or optimize the way you regularly use internal systems. If a laptop overheat on a regular basis could be expensive to repair or replace parts. In many cases, it becomes unusable, resulting in a significantly increased investment for a replacement.
