Laptop use patterns research on product lifetime and obsolescence aspects

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.
