sorry to break it to you but its doubtful you'll get a dvd thats specific to your laptop as pretty much every one is different in the way its put together, in general there are a number of screws on the bottom that'll need to be undone, however this will void your warrenty, i've opened a couple of laptops and ALWAYS had trouble, now i just avoid opening them.

what type of laptop do you have? age etc?

even if you do manage to get inside you may have to get a replacement part? and i wouldnt advise self-soldering, thats asking for trouble on such a small scale.

try getting in touch with the manufacturer, see how much it would cost for a repair from them.
