I had a doubt when I received it (the story jumper which I had forgotten about: p) but it has revived my old acer 1510. I replaced my hitachi 4200 rpm 60Gb ( died after 10 years of service), replaced by the 512 2Gb of RAM (bought on amazon too) and in 2004 bought my pc boot in less than 10 sec with windows XP and now start 15 sec under Windows 8.1 ... !! !
Perfect investment to revive any old laptop cheaply.
