The Realization Of A Portable Reinforced Notebook Computer Based On ETX-Module

This paper introduces a new framework based on ETX reinforcement of notebook, computer implementation process. This article in view of the current reinforcement notebook computer, introduces the demand based on ETX architecture notebook design principle and the mainboard PCB design, and gives the commissioning test method.The first chapter presents the current reinforcement notebook computer field the situation and development characteristics, and the strengthening of notebook computer system is introduced.The second chapter presents design the principles of a notebook computer motherboard, mainly including various bus connection realize principle, and total offline extended out each interface. Notebook computer motherboard adopts ETX architecture, according to the actual need to elicit some non-standard interface, the other functional modules were integrated to a substrate, greatly reducing the space occupying space. This paper introduces each part of the circuit, specific design of the notebook computer motherboard, including the circuit principle, interface definition and design rules. four ETX socket (clamps its X1～X4) were designed on the motherboard as the core, in the surrounding, power, A/D, I/O and PCI/ISA interface circuit, etc. were designed.The fourth chapter introduced the machine commissioning test process. At the motherboard debugging tests, power load and reliability testing were test at the first part, and then each interface were tested.The paper finally to this research content and result of summarized, and prospects the development prospect.This reinforcement notebook computer has a high processing speed, low power consumption, and is easy to expanded, has wide working temperature range, anti-corrosion, good effect, EMC etc, and is a good portable laptop computer suitable for each wild environments.
