I bought an Asus Laptop K55n DS81 at an auction. I have no idea of what it is or what it can do. I went to the ASUS site but was not able to find a manual. I'm not expecting much for a very inexpensive but working laptop but would like to know what it can do. I don't know for sure what OS is loaded. I am guessing Win 8 or an upgrade to WIN 10. Any suggestions would be appreciated.
