They claimed that it's 100% gurantee and charged 85 for diagnosis, however, after I paid more than two hundred bucks to fix my laptop there, the same problem occured in two weeks! I called them back and the answer was: there might be other problems so we will have to charge you again another repair labor fee and parts...! What a crXp, for 400 I could have bought a new one. Don't believe in what they told you... there is NO gurantee that your laptop wll be fixed. So, After wasting money there, I still end up buying a new one.
