Nowadays, a laptop computer is one of the electronic devices that important for students to use as a learning aid during their studies. However, an existing laptop computer always have a problem in terms of hardware quality which may cause perishable and unfriendly hardware repairs. In this paper, an existing laptop computer towards sustainable development is investigated and propose a new design concept of laptop computer based on consideration of environmental, economic and societal aspects. Design for Six Sigma (DFSS) methodology and Design for Disassembly (DfD) approach are used along the process of investigation and improvement. The DFSS methodology uses six phases which each phase is integrated with a design tool; Define phase uses questionnaire for gathering information of customers’ needs, Measure phase uses Quality Function Deployment (QFD) method to measure customer satisfaction, Analyse phase uses Morphological Chart and Weighted Rating Method to generate new concepts and select the final concept, Design phase uses Computer-Aided-Design (CAD) software that involves in designing and assembly of laptop computer components, and Verify phase uses SolidWorks sustainability analysis to compare the proposed design concept of laptop computer with two existing products. DfD approach has been implemented during Analyse phase of DFSS in order to improve the design of laptop computer to be disassembled for easier maintenance, enhance serviceability and configurations that allow for cost-effective separation and other related processes including reuse, remanufacture and recycling concept of laptop computer components. As a summary, a new design of laptop computer has been illustrated to overcome the stated problem. This study is intentionally proposed for the future laptop computer design configurations in order to achieve sustainable development goals.
