Solar Power for Notebook and Laptop Computers

Executive summary about Laptop Power Supplies by EM Beck

The solar cells that you see on calculators and satellites are photovoltaic cells or modules. Photovoltaics, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity.

The energy knocks electrons loose, allowing them to flow freely. For example, the current can power a calculator. This current, together with the cell’s voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.”

As energy costs and energy conservation continue to garner interest as mainstream issues, we should see the rapid development of solar integrated design features.

Hand Held Solar Kits

Solar kits combine solar cells, rechargeable batteries, and a wide selection of cables. These won’t power a portable laptop yet unless it’s a miser on energy, but they will keep you connected with a limitless power supply for your cell phones, Smart phones, PDAs, and smaller devices.

Portable Solar Power Docking Stations

The idea of using solar power in remote situations is nothing new. The question for us is how well, and how fast, a solar power station will power up your notebook or laptop.

There are very few winners in the category of a portable solar power docking station to efficiently run a laptop computer. One that does get good reviews on the subject is the “PowerDock System”.

PowerDock Systems are relatively expensive, and range in price form a few hundred dollars on up to $450. The PowerDock is an attractive product design an weighs in from 5 to 13.5 pounds.

Another potential winner is the Notepower Solar Laptop Charger from Sierra Solar Systems. The 3 lb. Notepower is not designed with a storage battery, but the 20-30 watts of power will charge and run most laptop computers, according to the specs.

You may not consider the Notepower as a true solar docking station, but it is an attractive portable solar package for a temporary power solution. Originally priced around $250.

Commercial and Military Grade Solar Power Systems

Some of the best remote solar power systems are designed to meet military standards. Energy Technologies, Inc. in Ohio, USA makes a wide assortment of military standard power equipment for field use.

Things like field deployable inverters, converters, UPS, engine-generators, along with solar power stations with the trade name Tactical Solar Products.

We have looked at several of the many possibilities for solar power, and going “green” with remote computing. Some of the solar power resource websites you might want to keep an eye on include: Altapower.com, RadioLabs.com, and CTSolar.com. As computing devices become smaller and more mobile, and with nascent technology soon to push the boundaries of wireless networks, solar power could prove to be a factor in your computing future.

Refurbished Computer

A Refurbished Computer Saves Your Money

Executive summary about Refurbished Computer by Victor Thomas

refurbished desktop computers

Refurbish computers are available with computer retailers. The dealers, who exchange new computers for used ones, refurbish the returned used ones and offer to sell them at heavily reduced rate.

It usually costs less without a monitor. It is to be remembered that some of these refurbished systems are not condemned pieces. There are various reasons for such systems to reach for second sales as refurbished.

Some of the customers prefer to buy refurbished ones, because they have already bought an expensive system, and require a second one for family use.

An important advantage of the refurbish system is that it is upgradeable in case the buyer wants to add accessories like hard drives, memory, faster modems and DVD drives. All these additional accessories are available online, including monitor.

Discount Refurbished Laptops

Executive summary about Refurbished Computer by Jimmy Sturo

Refurbished laptop computers are generally used with the manufacturers original standards. Mobile computing has been made a lot easier and more affordable with refurbished laptop computers. These refurbished notebook computers contain the latest technology.

IBM, Dell, Compaq, and HP do not sell new or refurbished laptop computers unless they meet their standards because each company’s reputation depends on it. Hence, refurbished laptop computers are trustworthy as well as being cost effective.

Refurbished laptops are a good value as with refurbished laptops and refurbished notebooks the customer gets upgraded models with faster speeds, more memory, and more features at a discounted price. Some manufacturers offer a two-year extended warranty in many cases.

Micro Computers

History of the Computer - Computers and Technology

Executive summary about Micro Computer by Michael Cooper

The first basic types of computers were designed to do just that; compute! One of the first computers was called ENIAC.

It has become difficult to believe that computers have evolved into suitcase sized micro-computers of the 1990’s.

Computers eventually evolved into less archaic looking devices near the end of the 1960’s. Most computers at this time were termed “mainframes” due to the fact that many computers were linked together to perform a given function. The primary users of these types of computers were military agencies and large corporations such as Bell, AT&T, General Electric, and Boeing.

The United States was attributed the title of pioneering the computer. This resulted in newer components and smaller sized computers. The use and operation of computers had developed into a form that people of average intelligence could handle and manipulate without to much ado.

Many people say that the predecessor to the computer was the typewriter. Children are being taught basic computer skills in the classroom in order to prepare them for the future evolution of the computer age.

Blaise Pascal is usually credited for building the first digital computer in 1642. In 1671, Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. While Thomas of Colmar was developing the desktop calculator, a series of very interesting developments in computers was started in Cambridge, England, by Charles Babbage (of which the computer store “Babbages” is named), a mathematics professor.

Computer styles and types covered so many different functions and actions, that it was difficult to name them all. The original computers of the 1940’s were easy to define their purpose when they were first invented. They primarily performed mathematical functions many times faster than any person could have calculated.

The computers of the 1990’s roughly fell into three groups consisting of mainframes, networking units, and personal computers. Mainframe computers were extremely large sized modules and had the capabilities of processing and storing massive amounts of data in the form of numbers and words.

Mainframes were the first types of computers developed in the 1940’s. Users of these types of computers ranged from banking firms, large corporations and government agencies.
