This laptop was provided by my father's office. I replaced the hard disk with an SSD to make it run faster, and it is now perfectly smooth—you will see for yourself when you test it. Note that the battery is missing, and an external keyboard is being used as the built-in one is disconnected. You can easily add more RAM if needed. I am selling it because I don't need it for my office work, and it might get damaged if left unused.
