Know the Seller

There are only three types of used or refurbished laptop sellers: retailers, private sellers, or scammers. It’s imperative to know from whom you are buying because that determines how you approach the buying process. You deal with a private seller very differently from an online retailer. Of course, if the online merchant is a reputable e-commerce site (some examples listed below), then you shouldn’t need to worry about this, but there are some great deals to be found online if you stay educated and wander outside the standard computer stores. There are several red flags to watch out for when determining with whom you are dealing (and if you should deal with them at all!):

-Check the feedback. Is there a feedback system on the site? If the seller seems to be a merchant, do they have consistent track record providing the product you want to purchase? If the seller seems to be an individual, do they have more than one model for sale? It would be unusual for a private seller should to have more than one model for sale at a time – if they do, be suspicious.

-Check the payment method. Are the payment terms odd or inconvenient? Do they only accept Western Union? (Never send money via WU to someone you don’t know. There is no recourse if you have trouble, and scammers know this!)

-Check the seller’s location. If the seller is international, this shouldn’t be an immediate red flag, but if they are international and offer free shipping, this is a major red flag. This wouldn’t be cost efficient for anyone but a scammer.

-Check the photos. Are there any actual photos of the laptop? Generally, a scammer doesn’t have the actual product in hand to take photos, but keep in mind that they can easily swipe photos from a personal website. The absence of real product photos does not indicate a scam, but it should be considered as a part of the bigger picture.

-Check the time. Is the seller in a major hurry? Is it a 2-day auction? Legitimate sellers can also be a in a hurry, but if you feel that the seller is really rushing, make sure to take this into account.

-Check the deal. You know what they always say: “If it sounds too good to be true…” I hate to be the bearer of bad news, but totally unbelievable deals are just that – not believable.

Bottom line: If you feel suspicious, listen to your gut. A private seller that is trying to come off as a retailer will probably have holes in their story that you can expose by checking for red flags. A private seller trying to scam you probably won’t have their ducks in a row well enough to pull off a swindle on an educated consumer.

Know the Products.

There is a difference between a used laptop and a refurbished (reconditioned, remanufactured) laptop. A used laptop is just that – used by another person for a certain period of time and now it needs a new home. Perhaps the seller has cleaned up the notebook for sale, erased the hard drives, and gathered up all the original manuals and packaging, but it’s possible he has done none of that. Refurbished, on the other hand, usually describes a notebook that has been returned to the manufacturer, repaired, cleaned-up, repackaged, and sent out with a short warranty period attached. These laptops are generally sold by an online retailer, so you often have the security of knowing you may be able to hold them accountable for problems (though you can’t be sure of this – check their specific policies). Of course, ‘refurbs’ also come with a higher price tag, but you pay for that added security. It’s possible that a refurbished system will have some light surface scratches, but most often you can’t even tell that the unit was ever used.

Some things to keep in mind when shopping for a used (not refurbished) laptop:

-You will probably need to buy a new battery. There are specific draining and charging procedures for laptop batteries. Chances are that the seller did not always follow these procedures (does anyone?). Make sure to account for the price of a new battery when you are shopping so you aren’t hit with an unexpected after-purchase cost.

-You really have no idea what that laptop has been through. Laptops were created to be mobile. You really don’t (and can’t) know how many times that laptop was dropped, spilled on, walked on, etc. While the seller is obligated to disclose any known defects, you can’t be certain to you are hearing the whole story. These undisclosed accidents could cause you problems down the line.

-Expect some scratches. With movement comes scratches, so depending upon the age, expect a certain amount of wear and tear. If you are prepared for this, you won’t be as disappointed. If it doesn’t affect the performance of the computer, try not to worry about it.

Know Where to Buy.

While you can scour any laptop-related site for potential for sale ads, you also end up wasting a great deal of time that way! Instead, there are a handful of high-traffic websites out there that consistently have used laptops and refurbished laptops for sale. Here are a few:

http://ebay.com

http://overstock.com

http://tigerdirect.com/applications/overstock/

http://techdepot.com/clearance.asp

http://notebookforums.com/forum25.html

If you are in the market for a used or refurbished laptop, you should take some time to get familiar with market conditions and the systems that tend to become available. If you are researching on Ebay, watch some auctions to see how the bidding goes. Get very comfortable with used laptop pricing before you get emotionally attached to any one system. If you are shopping in a more retail environment, like TigerDirect.com, you won’t need to watch prices change like an auction, but the inventory changes often and if you don’t see what you want there now, keep checking back. Make sure to check return policies on refurbished systems to avoid any possible buyer’s remorse.

Used and refurbished laptops provide an excellent opportunity to get a nice laptop at a very nice price. While the prices are much easier to swallow than new units, buying used does come with a certain set of risks. Education is power here (and money in your pocket, in the case of a scam), so stay ahead of the game and don’t rush into any to-good-to-be-true deal without making sure you know what you are getting. If you do your due diligence, you should end up with a quality system for a fraction of the new price.

Just like your car, your laptop computer battery lasts longer depending on how you “drive” your laptop. Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won’t charge fully or stops holding its charge for as long; when this happens, you’ll probably want to buy a replacement battery.

When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.

Types of Laptop Battery

•The nickel cadmium battery, known as NiCad (pronounced “Nigh-Kad”), used to be the most common type of laptop battery. Nickel cadmium batteries couldn’t hold very much power by today’s standards, and could only be charged a limited number of times. NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the “memory effect,” meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it.

•The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect, although it wasn’t as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn’t have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.

How Increase the performance of Battery?

Regardless of which type you have, it’s important to properly care for your laptop battery, in order to get as much life out of it as possible.

•”Conditioning,” which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery.

•Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it’s a good idea to condition all laptop batteries regularly, rather than simply leaving them plugged into the wall at all times.

•Your laptop battery should never be stored in an area that drops below 50ºF (10ºC) or rises above 95ºF (35ºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled.

•Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.

Just like any other battery there are cells inside a laptop battery. Each cell is typically 1.5 volts and a number of cells are arranged in series and connected in parallel to deliver optimum power to the laptop or device. A number of cells are connected together to forma a battery. Connecting a number of cells in parallel means to connect all the negative terminals to each other and positive terminals likewise this increases the power delivering capacity of the battery but not the voltage. Then a number of these batteries are connected in series (negative to positive terminals to raise the voltage). This is done to optimize the voltage level of the battery. These cells are controlled by an internal electronic circuit in the battery.

The internal electronic regulator is the unique property of a laptop battery. This circuit regulates the flow of charge into and out of each internal cell in the battery thus ensuring that each cell has an equal charge at all time in turn ensuring the optimum use and long life of each cell. It also ensures that the cells do not over charge.

The plates of each cell react with the electrolyte (chemical/acid) in the battery causing a flow of electrons from the negative to positive terminals and a flow of ions from the positive to the negative terminal this is the flow of current as we know it. This flow continues until the electrolyte loses its acidity. When the battery is charged the ions are restored to their place in the cell and the electrolyte regains its acidity ready to generate electricity in the cell once again. This process is always the same irrespective of the type of battery.

The process of charging or discharging of the battery is controlled by hardware built into your laptop. This hardware ensures the proper functioning of the cells in the battery and warns you of the tile left before you need to recharge the battery. This indicator is displayed in the right bottom corner of the screen in most notebooks or laptops.

Though the laptop battery is rechargeable, like everything it does have a life span and cannot go on serving you for eternity. Proper care will ensure that the battery lasts longer than it would without the proper care. A battery will normally last between 500-700 charge cycles before it will need to be replaced with a new one. The number of charge cycles of the battery will depend on the usage of the laptop. The more often you need to charge your laptop the sooner you will have to replace the battery.

Every laptop model is designed to suit a particular function and so is the battery designed to match the power requirements of the laptop.  The design of the battery depends on the weight and size of the laptop. A small light-weight laptop will have its design defeated if the battery weighs more than the laptop itself, so the battery has to be designed to suit the model of the laptop.

GRAPHICS: First, the best laptop for gaming, will have the best, quickest and latest possible graphics. When considering a laptop with the purpose of gaming make sure to look for the latest graphics card as well as the quality of the graphic chipset. Also be sure to check the specs of the laptop to see if you could upgrade the graphics card on your laptop as the need arises (for most laptops this is standard).

Some of the best graphic chipsets are NVIDIA, ATi Mobility Radeon 9700, Intel’s Graphics Media, or ATi’s Mobility FireGL V3200.

The ATI Mobility Radeon 9700 graphic chipset will make your laptop perform a variety of functions, including 3D, HDTV, mobile video editing studio and graphic processor. Also the Radeon 9700 is not only a quality Graphics Card it will also give you better performance while saving battery power.

Other common graphic chipsets include, Trident S3, STMicro, 3D Labs, Matrox, and SIS.

RAM: RAM is a crucial factor in getting the best laptop for gaming. Simply put RAM, or random access memory, refers to the amount of programs you can run on your laptops without running into slow downs. 512MB of ram is optimal for the serious gamers as this will allow for the large memory needed to run graphics that are required for gaming. Basically more RAM equals a better laptop for gaming. Some laptops come with as much as 2GB of RAM! RAM is essential for running video graphics, 3D, and for gaming in general.

Laptops also have what is called dedicated video RAM (VRAM) that is memory, which usually comes with a graphics card (ATI Radeon, NVIDIA GeForce, etc…) and has its own memory in MB which includes 32MB, 64MB, and 128MB. This is a special RAM that is used by the video adapters inside the laptop and only handles graphics and visuals. VRAM is especially helpful for 3D gaming. Today NVIDIA nForce is considered as one of the best graphics card.

Overall the best option for gaming is to pick a laptop with the highest VRAM graphics card you can afford. A good way to find out what memory you might need is to refer to the back of your games or media software CD-case or manual to see the “system requirements” for the video memory requirements.

The best laptop for gaming has lots of CPU speed. Nothing is more annoying than to be in the middle of a game and have the computer freeze or crash. The processor is the computers brain or center and the quality determines how your computer will perform. The speed of a processor is presented in gigahertz (GHz}. While there are many brands and types of processors, one of the best available today is the Intel Core 2 Duo. And the best laptop for gaming has a speed of 2.4GHz or more.

As far as the hard drive goes, it is best to go with a SATA. SATA, or Serial Advanced Technology Architecture is best for laptops, it uses less power than other hard drives and is not limited to a particular clock speed. Make sure to check the hard drive speed, 7200rpm is the highest and best for for a gaming laptop.

SCREEN/DISPLAY: The screen specifications for gaming laptops play an important role. Obviously the bigger the better, a 17 inch wide screen will deliver a magnificent gaming experience. Resolution and display quality should be able to handle the graphics for 3D gaming.

While there are several display resolutions available, today the best is WUXGA, which stands for Widescreen Ultra eXtended Graphics Array and is a display resolution of 1920 by 1200 pixels (2,304,000 pixels) with a 16:10 screen aspect ratio.

So in the end the best laptop for gaming is a combination of graphics, ram, processor speed and screen display. Keeping this formula in mind when purchasing your gaming laptop will provide you with the ultimate gaming experience.

Because of these superior features gaming laptops come with a huge retail price tag. Something to consider is in a world where the Internet provides a huge arena where lots of sellers and merchants compete for your business, lots of money can be saved by avoiding retail merchants and purchasing a laptop for gaming at a discount.

The performance of a laptop’s battery depends upon its physical devices that require more electricity to operate. The hard drive, the floppy drive and the CD-ROM are the devices that sap up maximum power.

The computational programs and the calculation processes used by spreadsheet applications and database programs engage the processor to a greater degree as well resulting in large consumption of electricity. Other physical devices that consume greater strength of battery are audio and display devices. The display panel also consumes lot of electricity. The brighter the screen appears, the more electricity it is consuming. Video applications also have an intense effect on electrical needs, due to its usage of virtual memory. Laptop batteries, like other batteries, start discharging faster as they age.

Now if your laptop’s battery is giving frequent problems then go for a replacement. The best option is to go for online shopping portal like gadgets.in, and select suitable laptop batteries for replacement. There are laptop batteries of all makes that will replace the ageing battery of your laptop to make it all new and latest. The brand new battery will be proffered to you at a bargain price that will fit your laptop perfectly. The only thing that needs to be done is to correctly identify the model and serial number of your laptop battery and verify the Voltage and Amp rating prior to your purchase.

Before placing order for a replacement battery at Gadgets.in, view the model and serial numbers labeled on the bottom of the battery. For this, remove the battery from the laptop and you’ll see that the battery serial number is printed in black lettering beneath a barcode. After the removal of the ageing battery from the laptop do plug in the AC adapter to provide power to your laptop until a replacement battery arrives. After serial number verification, a new battery will be shipped to you promptly. All laptop batteries are built with the highest quality cells and appropriately meet the original manufacturer’s specifications. The low overhead provides the finest laptop batteries at great prices along with guarantee of quality.

So where do you begin?  If like me you use a computer for research and keeping in touch with friends and family, you will probably have a basic knowledge of some of the terms used (or at least of heard of them) within the computer manufacturing industry.  

As the credit crunch takes its toll and purchasers are cutting down on their spending, laptop sales have become more competitive.  So it is worth taking the time to find out what the terms used by the industry actually mean so you can make comparisons and a informed choice regarding your purchase.

I’m sure you are aware of the Internet; well in this competitive market many laptops include a wireless connection.  This will probably be top on your youngster’s requirements for their laptop features.  A wireless connection is abbreviated to Wi Fi which is the trademark name given to the technology used.  Other connections that are usually provided on laptops are: – A VGA port for a external monitor, a printer port, a 56kbps modem, and at least one USB port.  A USB port will be very important to your Son or Daughter; they are used to connect mouse/keyboard/, drives, MP3 players and digital cameras.

A student’s laptop should be light weight, robust and of a compact size that will easily fit into your teenagers backpack or under their arm.  Laptops are generally constructed to be tougher than before and should be able to with stand the odd knock and still function.

When purchasing a laptop check out how much RAM is provided, make sure there is enough storage space (hard drive) and computing speed to carry out any tasks it may be required to carry out.  This minefield sounds much worse than it is.  Simply compare the numbers products provide, some stores display technical specification breakdowns with the price of the laptop.  This makes it quite easy for non experts to compare what specifications you get for your money.

Although it is quite achievable to obtain a reasonable spec laptop on a low budget it is worth keeping in mind that you do get what you pay for.  You could find parting with a larger amount of cash initially could actually long term as a quality, higher specification laptop can last a good few years.  However if your child has a bad track record with phones and MP3 players (my Son has broken four mobiles and four MP3 players in the past two years!) it may be a safer bet for you to purchase a laptop as cheaply as possible.  Once your student has proved that they can look after their laptop and not cost you a fortune in laptop repairs you could consider upgrading to a more advanced laptop.

How can you sell your broken laptops? Where can you sell your broken laptops? If these are questions you have previously asked yourself then you will be interested to know there is one simple answer to both of these. Regardless of the condition of your laptop – Old, used or broken there is an option to cash it and not trash it, you can sell your broken laptop and this provides two main benefits; Cash in your pocket, and helping to reduce the increasing e-waste issues we are faced with.

The solution lies in electrical refurbishment companies – of which nowadays there is a wide selection available at the click of a mouse thanks to the growth of the internet.

A laptop computer is completely portable

Portability is often the main advantage of choosing a laptop over a desktop computer. Portability means that a laptop can be used virtually anywhere, not only at home and the office, but also during commuting, in lecture halls, coffee shops, libraries or in meeting rooms to assist with presentations.

You can use your time more efficiently with a laptop

A laptop can be used in places where a desktop PC can’t which means you can use your time more productively. For example, office workers can tackle emails during the commute to the office with a laptop at hand and students can work on coursework at the university coffee shop during a break between lectures. If you work from home then a laptop computer allows you to move your office outside on sunny days.

You can gain immediate access to information

Carrying a laptop means having instant access to information, whether it’s from saved files or from the Internet. Immediacy allows better collaboration between co-workers or students, as a laptop computer can be flipped open to find a solution anytime, anywhere. If you are in a meeting and have forgotten an important document you can simply access it from your laptop computer.

Laptops are a manageable size

Laptop computers are smaller than standard PCs which is great when space is at a minimum. When not in use, a laptop can be closed and put away in a small space unlike standard PCs that tend to dominate a large proportion of a room.

Low power consumption

A laptop computer is more power-efficient than a desktop. This is beneficial for businesses (which run hundreds of personal computers, multiplying the potential savings) and homes where there is a computer running constantly. You could even save money on your electricity bill if you choose a laptop computer over a desktop PC.

Peace and quiet

It can be distracting to work at a computer with a droning fan or one that sounds like it’s taking off every time you open a file. A laptop computer is often quieter than a desktop PC, due to better components and less heat production. This means cooling fans can be run at a slower speed and less often, giving you a quieter working environment.

Battery power

A fully charged laptop computer can run for several hours off its internal battery. This is useful for journeys but is also handy if there’s a power cut and you still need to get work done.

A laptop computer is a great investment whether you require a computer for work or for pleasure.

In the last artcile we know how to calibrate laptop battery. Now let me introduce some tips about re-calibrate laptop battery.

It is difficult to predict how long a laptop battery charge will last because each computer user has different habits and needs. The rate at which you use laptop battery power will determine how long you can use the battery of your laptop. You can re-calibrate your laptop battery if the battery’s life has gotten shorter over time. Your laptop battery might need a good calibration if it doesn’t seem to be getting the mileage that it should. How to re-calibrate laptop battery? The following paragraphs will give you the answer.

First put the laptop computer to sleep by turning off the screensaver and other power management settings of the computer. Then fully charge the computer and allow it to run all the way down until the computer shuts off automatically. Once the laptop battery has fully drained, charge it back up again and restore the screensaver and power management settings.

Re-calibrate your battery every month or so by fully charging, fully discharging, and then fully charging again. Basically to have a chance to re-calibrate your laptop battery is to turn off all power-saving features completely and then fully recharge them. If it doesn’t work for the first time then try two more full discharges and recharges.

The above way of re-calibrating thelaptop batteries works well with laptops using Ni-MH cells. But not with laptops using Li-Ion batteries because deep discharges will actually decrease the charge capacity and lifespan of Li-Ion cells. Moreover Li-ion batteries irreversibly lose approximately 20% capacity per year from the time of manufacture at a typical 100% charge level at 25deg.C, even when unused. Li-ion batteries irreversibly lose approximately 2%, 4%, 15% at 0deg.C, 25deg.C and 40deg.C respectively, when stored at 40% charge level. That is every deep discharge cycle decreases the capacity of the Li-ion batteries. As the Li-Ion batteries are chemical in nature, charging and recharging is not going to fix the problem once the chemical reactions stop happening. Therefore the best advice for re-calibrating the Li-Ion batteries is to store the battery at 40% charge if it kept unused for any unlimited period of time. Also don’t leave the battery in the laptop if you don’t use the battery or if you plug the laptop into outlet power.

You can also re-calibrate your laptop battery using Thinkpad T61 Battery Maximizer in order to maximize your laptop battery’s life. If your laptop has IBM ThinkPad Battery MaxiMiser and Power Management features installed, you can verify the condition of the laptop battery. You can check the status of your battery using the Battery MaxiMiser Gauge in the taskbar tray. The ThinkPad’s Lithium Ion battery pack that seems to be an intelligent battery uses a microprocessor to monitor its capacity. Then the microprocessor of the battery pack passes the information about the remaining battery capacity to the laptop. The laptop indicates the capacity with high accuracy.

Using the Dell Learning Utility, a modified version of a Win98 boot floppy, can also help you. Just place it in the floppy drive, and then turn on the computer. The re-calibration process is automated and takes about six hours to finish. This utility is available in different versions for different models. You can run the utility every two months.

If the laptop battery is still bad then it must have developed a memory that cannot be erased easily. If calibration doesn’t help, then it is the right time to purchase another battery.
