When you think of portability many people believed that you would not be able to get the power and functionality as compared to a desktop system, today is not true. Desktops are the preferred computer because of the ability to add peripherals and the power are much more than a laptop, but today laptops are able to add peripherals and have the computer power and have the ability to snap into a docking station which emulates a desktop. That has now changed and laptops are becoming affordable, light weight, faster and the ability to add many peripherals via USB.
Laptop computers are great portable offices, and as technology increases and speeds of computers increase, we are seeing battery life also increase and provide longer usage time with out the need to be plugged in. An extra battery is always a wise purchase when buying a used laptop. The batteries on many systems only last for about 2 years so if you get more life out of the battery you are one of the lucky ones. Battery life varies with the efficiency of the processor, so check out battery life in any reviews you read. When looking at the weight of the laptop don’t forget to add in the weight of the battery chargers and other accessories, this should be included in the weight of the laptop.
Manufactures are able to create tiny screens, even as small as 8 inches, this size screen is great for portability, but many people are finding that the fonts and images are to small and to use they need to start squinting. The size of the screen is also important. When looking at laptops look at the hinges of the screen and make sure they are strong and do not look like they would crack or separate from the laptop. Every so often you need to clean your screen and get the dust out of your keyboard, make sure you handle the screen carefully because the screen is fragile and can break easily.
Wireless is the wave of the future, so when looking to purchase a laptop make sure you get one with wireless built in. To use the wireless you will need a wireless router at home. This is always good to remember if you are using a wireless system make sure you make it secure so no one can steal your data or use your wireless system.
There is a variety of different types of memory, and it is important that you choose memory that is compatible with your notebook computer. Many computer owners don’t like to upgrade because of many reasons: they do not have the knowledge, fear of voiding the warranty or ruining their computers and some people don’t know what to order, or by opening the computer they might break the system and need to pay more to get it fixed. Like a lot of things in life, a computer memory upgrade seems more complicated than it actually is.
With today computers having the ability to add many peripherals be sure that the laptop comes with many USB ports to add devices like a mouse, printer, digital camera, etc.
If you are on tight budget, buying a refurbished laptop is a great idea. Many manufactures have refurbished laptops and will sell them at a reduced price which will save a lot of money. Many of the refurbished laptops even come with warranties.
A short intro : Supposed that i have 700$ to buy a laptop and I look over the internet to achieve my goal, then I take into consideration all the laptops I find, I compare them and finally I choose the one that I believe is the best. One last thing before I start : I will not take into consideration refurbished laptops.
Now, let’s begin. Here are the laptops I found :
Systemax Neotach Notebook PC
Lenovo 3000 C200 Notebook PC
Acer Aspire 7110 Notebook PC
HP nc6220 Notebook PC
Acer Aspire 3050-1594 – Mobile Sempron 3400+ 1.8 GHz – 14.1″ TFT
Lenovo – IBM Thinkpad R50e Notebook PC
Acer TravelMate 2480-2551 – Celeron M 420 1.6 GHz – 14.1″ TFT
Acer Aspire 3102WLMi – Mobile Sempron 3200+ – 15.4″ TFT
Acer Aspire 3690-2196 – Celeron M 420 1.6 GHz – 15.4″ TFT
Acer TravelMate 2480-2705 – Celeron M 410 1.46 GHz – 14.1″
Toshiba Satellite A105-S1013 – Celeron M 380 1.6 GHz – 15.4″ TFT
Lenovo 3000 N100 0768 – Celeron M 420 1.6 GHz – 15.4″ TFT
Lenovo 3000 C200 8922 – Celeron M 420 1.6 GHz – 15″ TFT
So I analyzed these laptops and I came to a conclusion. I took into consideration the type of processor, it’s FSB, the memory(most of them are 512 MB, but ones are DDR(333 MHz) and others are DDR2(533 MHz), which are better), the hard-drive(IDE or SATA-SATA is better)and number of rotations 4200,5600,7200, the video adapter, battery, the screen size and it’s type(wide or not) and, of course, the price.
You may be surprised, but sometimes not the expensive one is the better one.
I found two of them that i would buy. Here they are:
Acer Aspire 7110 Notebook PC – 699.97$
Acer Aspire 3690-2196 – Celeron M 420 1.6 GHz – 15.4″ TFT – 648.95$
I choose 2 because one has a display of 15.4″ and one a 17″ , both wide.In my case a 17″ display is not a problem because I usually use my laptop at home. And as a matter of fact, this is the one i would be interested in and this for 17″ display, for his hard-disk of 120 GB, for his DDR2 512 MB, for his DVD RW dual layer and his bluetooth. The processor is not the strongest, but is not bad at all.(1.46 GHZ at 533 FSB).
Desktops are passe. And in case you are still stuck with one, replace it immediately with a more convenient notebook or a slim laptop. Laptops were a luxury item at the time of their introduction, but as it happens with every technologically inspired product, they too became a necessity with the passage of time. Today, you wouldn’t be surprised to find every other kid in the block proudly boasting about or displaying his own. It is no longer just a luxury or a necessity, it is a device to be proudly owned and flaunted!
Laptops are such marvellous pieces of technology that they have taken the whole world by storm. Advancements are being made in it with each passing day and every new innovation becomes outdated even before it actually becomes known to the world. Prices of laptop too keep fluctuating with the latest ones being atrociously expensive and the precedent models immediately coming within your reach. Various factors that determine the price of any laptop are its brand, model and configuration. Always keep your usage and purpose in mind before going in for the laptop of your choice.
Laptops, no doubt, are expensive commodities. But with the advent of e-shops and Cashback portals, they are now well within the grasp of common man. Web offers cheap new laptops under various schemes at prices that are much lower than the high street. Plus, you also receive additional gifts and incentives in the form of cashbacks that such portals offer to their members. All in all, it’s the customer who gains the maximum out of the whole bargain. This exciting and innovative piece of technology is up there for grabs…click your mouse and it can be yours forver!
Laptops have often been thought of as simply a small, portable computer that can be taken anywhere you go (within reason!). There are actually four different types of laptops varieties currently available however, and it is important to know the differences between them, as prices, features and performance can vary greatly between these laptop genres:
Ultra light Laptops – Known as sub notbooks or ultra-portables, these laptops usually weigh no more than 4 pounds, and people who travel frequently usually love these types of laptops. Because these laptops weigh very little, they are easy to lug around in a backpack or laptop briefcase…but they are also very small. Typing on Ultra light Laptops, especially if you have large hands, is downright difficult and uncomfortable…make sure you bring along an external keyboard that you can hook up to your ultra light once you arrive at your destination. Ultra light laptops usually lack a CD Rom drive as well, so make sure you have the proper attachments before leaving home. Battery life on Ultra light laptops is usually excellent however!
Notebooks – This type of laptop usually weighs between 4-6 pounds, with screen sizes from 12-15″. As the laptop grows in size, battery life usually goes down as there are usually more devices and a larger screen to power. The Notebook is considered a ‘regular’ laptop, and usually has a large opening on the side where you can plug-in different devices like a CD-Rom drive, floppy drive, or wireless PCMCIA cards.
Standards – These laptops are the most commonly purchased types of laptops…they offer a full range of built-in features, including wireless connectivity, CD/DVD drives, network interfaces, multiple USB 2.0 ports, nice sized screens (usually 15″) and a keyboard that is easy to type on. You won’t need to pack along a lot of extra attachments for the standard laptops which is nice. Also, the best deals, discounts and prices can usually be found on standard laptops from all of the major laptop manufacturers.
Extra Large/Gaming – These bests are best suited as a ‘desktop replacement’. They are usually much faster, louder and have 17″ screens in most cases. The battery life is only about 1-2 hours as these laptops really burn through the power. Their faster processor speeds, larger screens, larger keyboards and heavier size makes them perfect ‘home / gaming machines’. Expect extra large laptops to weigh in excess of 8 pounds. These specialty laptops are also some of the priciest, and will almost always have all options built-in…no need to pack around an external keyboard or CD-ROM drive with these laptops…just make sure you bring a couple extra batteries though!
Make sure you purchase the laptop that will work for your needs, whatever they may be…buying a laptop that is too heavy if you are a frequent traveler will leave you exhausted from hauling it around. Buying an Ultra light laptop if you are a gamer will leave you disappointed. Make sure you evaluate your needs before purchasing your next laptop, and you’ll be smiling instead of grimacing in frustration!
A laptop battery provides a source of electrical energy that supplies needed power to your laptop. The laptop battery uses a combination of cells that are electrochemically active, which is to say, they naturally transmit electrons from one end of the laptop battery to the other, when those two ends are connected in a circuit. A laptop computer battery can be engineered to be highly portable, like a watch battery, or it can be built to withstand extremes in operating conditions, like a car battery.
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
&bullThe 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.
&bullThe 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.
&bull”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.
&bullSome 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.
&bullYour 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.
&bullAlso, 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.
