The product, explained
About the Lenovo Flex 15
Lenovo 59404159 is listed in the laptops category. The recorded specifications include display diagonal: 39.6 cm (15.6"); processor family: Intel® Pentium®; internal memory: 4 GB; total storage capacity: 500 GB. This entry covers manufacturer code 59404159. Specifications relate to this exact source record; other editions or packages may differ.
The 39.6 cm (15.6") display is specified at 1366 x 768 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
This configuration lists 4 GB of memory and 500 GB of storage. Memory supports active applications; storage holds software and files. Check upgradeability separately, because a capacity figure does not establish whether either component can be replaced.
