Laptop use patterns research on product lifetime and obsolescence aspects

Cetinkaya, Esra; Woidasky, Jörg

The aim of this study is to acquire information on the user behavior of laptop (including notebooks, laptops, subnotebooks, netbooks, or ultrabooks) users. A questionnaire-based survey was carried out at a University in Southwestern Germany in 2015, and duplicated in 2018. Results show amongst others that on average no defect occurs immediately after the manufacturers’ warranty period. About 80% of all devices worked flawlessly throughout their use phase. Life time expectation for the devices clearly exceeded 5 years, but the actual use phase duration was found to be only about 80% of this time span. Almost 2/3 of all predecessor notebooks were stored after the end of their useful life, and only 11% disposed of.
