depends on the laptop. make/model? if the bezels come apart, just take it slow and careful. also, make sure you have the right fit of screen -- double-check with the cats on the notebookreview.com forums, since it's more than just the diagonal size that defines a proper fit (and some 13" laptops take 14" screens, etc). once you've got the right fit of screen and removed the bezels (if they can be removed without a special tool, or at all), it's pretty easy to disconnect and reconnect the old screen, since they all largely use the same adapter. make sure you retain any tape or fixtures that were used to hold the cabling in place and reapply it. that's all!
