laptop battery

The history of computer: Some of the earlier mechanical counting machines lacked the technology to make the design work. For instance, some had parts made of wood prior to metal manipulation and manufacturing. Imagine the wear on wooden gears. This history of computers site includes the names of early pioneers of math and computing and links to related sites about the History of Computers, for further study. This site would be a good Web adjunct to accompany any book on the History of Computers or Introduction to Computers.

Who invented the computer?” is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention.

The history of computer:

Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980’s. A 340K byte bubble memory lap-top computer with die-cast magnesium case and folding electroluminescent graphics display screen.

Finally in 1986 a true laptop was created by IBM called the IBM PC Convertible. I say true because unlike a few of the others, this laptop didn’t have to be setup everywhere. And unlike the others it featured two modern 3.5 inch floppy drives, and space for an internal modem! Also found on the Convertible was an LCD screen and basic applications the user could use to create word documents, and schedule appointments.

Maybe most interesting was that the IBM PC Convertible sold for $3500! Of course you would be hard pressed to find that price tag on any laptop these days(They have gone way down).

Since the late 80s many manufacturers have come forward to produce new machines that are even faster and more powerful than their previous counterparts. These days the buyer has a lot of choice, and laptops are faster than ever.

The front of the Studio 15″ houses just the IR Remote control port. The left side has the Wi-Fi switch, the security lock slot, 2 USB 2.0 ports, Ethernet, Mic & 2 headphone jacks, the Expresscard slot and the Memory card reader. On the right are 2 more USB 2.0 ports, the optical drive, firewire port and the power button.

Just as green LEDs were rendered tacky almost overnight by the surge in blue bulbs, blue has now have given way to white, which gives a clean look, glowing wonderfully brightly against the glossy black interior.

Above the keyboard are an unfussy array of touch sensitive media controls and Dell continues to use slot-loading optical drives, something that never fails to aid any notebook’s aesthetic. Overall, it’s very neat and tidy, while the addition of an ExpressCard remote is a welcome and increasingly essential addition.

The Studio 15 follows Dell’s recent, and welcome, trend of putting HDMI outputs and touch-sensitive control buttons on just about every laptop–you can also get those on even the cheapest Inspiron 15-inch.

Lenovo Thinkpad has released lots of new versions, the specification is the most important thing, which is concerned by users mostly, so what is the specs of Lenovo Thinkpad T400, I will have a review on it here.
• Operating System: Windows Vista Business
• Processor: Intel Core 2 Duo T9400
• Processor Speed:2.53 GHz
• RAM: 2GB –> 8 BG
• Weight:5.6 lbs.
• Display Size: 14.1″
• Graphics: Switchable Intel GMA 4500MHD and/or ATI Mobility Radeon HD 3470
• Storage Capacity: 160 GB
• Networking Options:802.11 a/b/g/n
• Primary Optical Drive:DVD +/- RW
The Lenovo Thinkpad is one of those laptops that really bridges the spectrum when it comes to cost and specs. The Thinkpad T400 is right in the middle of it all with a modest internal setup that’s great for business or heavier home computing, which should be expected for around $1,400 to $1,600.
Right off the bat, the T400 offers one huge perk in switchable graphics, which means this machine can speed up your day to day computing and save battery life on the go with it’s lower power Intel GMA graphics set. But you won’t sacrifice higehr end video and graphics with the ATI Mobility Radeon setup wunning in sync with the Intel Core 2 Duo processor running at 2.53 GHz. Not too shabby.
But, of course, all this bulky internal work brings up the weight. And, Lenovo hasn;t really caught on to the design trend. So, if you don’t mind a heavier, less attractive laptop for work, the T400 is perfect. But, for more specilaized home laptoping and for those with a design flair, keep looking, as there isn;t anything here you can;t find elsewhere.
Now, how about the specs of the Lenovo Thinkpad T400, I think you do have a conclusion in your mind, if it is worth to buy, each have their own idea.

Nowadays, lots of brands of laptops are in furious competitions, like Toshiba, Sony, HP, Compaq, IBM, Dell and others. However, who is the NO.1, we still do not have an answer, let’s discuss between Asus and Acer, these two brands now, and find the best one here.
Asus created the Netbook category a little over a year ago when it introduced its first Eee PC. Acer jumped in this past summer with the Aspire One and has overtaken Asus for the top spot in the Netbook market. According to research firm DisplaySearch, Acer sold 2.15 million Netbooks in Q3 for a 38.3 percent share of the Netbook market. Asus moved 1.7 million units for 30.3 percent market share. Not only did Asus have a head start in this horse race, but it also has a much larger stable of Netbooks. It seemingly releases a new Eee PC model every other week, while Acer has but a few versions and colors of its 8.9-inch Aspire One.

HP sits in a distant third with a 5.8 percent share of the market, followed by MSI (5.7 percent), and Dell (2.8 percent).

On the whole, the Netbook category grew 160 percent in Q3, which is good news, given the current state of the global economy, but not all that surprising when you consider that the category has gained momentum with many of the big names jumping into the fray.
Now, the answer is obvious, who is the NO.1, there is no need to point out. But both of them are quickly developed, what is their future levels, we still have no result.

When it comes to choosing a cheap laptop or notebook, there is one thing to be certain of, there is so much debate between everyone whether a laptop and notebook are the same or completely different. On one side of the debate, you have many experts agreeing that the two are completely different. Going by the concept that a laptop is a portable computer while, a notebook is for taking notes, they will argue the point until your eyes cross, pointing out all sorts of things like a notebook is defined by many different companies as having different options from the type of processor, to the RAM, and even the optical drives. When you look at this concept, a notebook would be a veritable note taking machine which has no problems what so ever running word processing capabilities, internet access and can even come with an optical drive for means of storing data.
On the other side of the table you have the laptop, which of course has more processing capabilities as well as RAM and have no problems running multimedia programs as well as high-end development software like CAD or even Dreamweaver and Photoshop. However the concept them becomes even more confusing when you start to realize that some computer companies use the terms loosely and call all of their portable computers one or the other. Some even separate them based on their capabilities and as a result a long standing debate has developed between experts in the field as to whether they are the same exact thing or completely different.
According to the first set of experts, if you are looking for a cheap laptop notebook, you go with the notebook because it has less features which makes it cheaper. On the other hand since many companies call them either one or the other, this will make the decision process that much harder. Instead of thinking whether you want a cheap notebook or laptop, you should instead think about the features you need in the particular mobile computer and just look for one that is affordable and has all the features you need.
Do not allow yourself to get dragged into this debate, it is not worth all of the effort, just think of it as a mobile PC and nothing more. Otherwise you could spend many days looking for a cheap notebook or laptop when in fact you need the other one. Save yourself some hassles and sit down to think about what it is exactly you plan on using the laptop for and go from there. Once this part is out of the way, finding a cheap notebook/laptop will be a much easier task because you know what you need and can then compare prices looking for the cheapest, without having to give up any features.
