Asus provides free downloadable copies of manuals for the laptops that it manufactures. The manuals are provided in PDF format. To locate the manual for a specific device, enter the laptop's model number in the search box on the Asus support website, and select the Manual and Document tab.
Manuals for some older-model laptop have been removed from the Asus support website, as of 2015. Third-party websites, such as Manual Owl, may have archived copies of those older manuals. To open PDF files, use the free Adobe Reader application that is available for Windows, Mac and most smartphones or the Okular app for Linux.
