The first portable computer was known as Osbone 1 which was developed in 1981.
This heavy and cumbersome machine used CP/M operating system which means Control program monitor who was commonly used in 1970s before the MS-DOS wiped it out after the introduction of the IBM PC in the year 1981.
Finally professionals were able to move around with their data and information on a portable computer. The only problem was that it had to be plugged on an electric socket since it could not use batteries.
Kypro 11 was developed as perfection rather than a competitor of Osbone 1. It had twice the size of Osbone 1 when it came to the screen features and when purchased new, it came with a software bundle and it had twice the storage capacity and double density floppy drives as opposed to that of Osbone 1.
Next in line came the Bondwell 2 which was not released until 1985 which came as a result of the operating system decline of CP/M. The Compaq was introduced in 1983 at a time when standard computer platform was looked upon IBM Personal Computer.
Other laptop models that followed Epson PX-4, the NEC PC 8401A,PX-8 and NEC PC-8500. None of these four units came with standard hard disk or floppy although they made use of the CP/M modified system in the Rom.
On November 2005 the then UN Secretary General together with Nicholas Negroponte unveiled a rough prototype of the laptop computer.
When it comes to the choice of a good laptop battery charger, culpability is a factor that should highly be considered when purchasing a laptop battery charger.
It is always advisable to check on the user manual to ensure the necessary specifications have been followed in order to avoid purchasing a charger that might damage the computer battery.
It is important to go for the best quality because the charger immediately becomes part and parcel of the laptop just the same as the battery.
There are several types of laptop battery chargers and one of them is the solar charger which basically converts the energy got from the sun into electric energy through a process known as the photovoltaic effect.
The solar chargers are preferable because they are environmental friendly because when they recharge the batteries then the batteries can not contribute to the land fills.
Therefore be sure to go for a quality laptop battery charger.
