You would have to go back to the World War II period to find the first digital computers designed by an army of engineers that were both factory-sized and capable of unique computers to solve simple mathematical operations. Laptops have evolved since the first one was created. As technology improved and financial availability became more consumer-friendly, the microcomputer revolution began. The market for printed circuit-equipped microcomputers has grown to approximately 100,000 units due to improvements in microprocessors, a standard operating system, and increased availability of software, disk drives, and memory cheaper. By the time Dell's portable devices hit the market, portable devices had advanced immensely. Several computer manufacturers began to appear around this time: IBM, Apple and Compaq. Dell was founded in 1984 by Michael Dell, who started upgrading IBM-compatible personal computers in his college dorm and then sold them door-to-door. Dell's business model is what ultimately led to the success of the Dell Company. Dell used the same principle that Michael Dell created in his university project: eliminating the middleman. The company sold its products directly to its customers rather than selling them through distributors. Dell used door-to-door telephone representatives and field representatives to serve its customers. Dell's high growth rates and attractive margins allowed it to finance its growth internally, allowing it to receive orders from government organizations and oil companies. By 1985, Dell was worth $6 million. Dell changed its strategy to begin offering made-to-order computers. By the end of the year, the company had generated $70 million in revenue. Competition in the computer industry was intense, middle of paper, but no one was able to make the battery work in larger devices, a computer being one of them. For a while, it was unclear whether customers were excited about the new technology. But a new battery wasn't the only available power option the production development team could use. The second option was to create an ejectable disk drive and replace it with a rechargeable battery. Dell's production team ultimately knew they wanted to go with LiOn technology. As for the decision that Dell's production team should make, it should be along the lines of convenience. Dell should make the decision to use LiOn technology battery because it is more convenient for buyers. Using an ejectable battery would be inconvenient for customers and also put the product at greater risk of malfunction. LiOn technology battery is definitely the way to go.
