I've taken my Toshiba L455 apart a few times from watching a few different You Tube videos. I WISH I would've seen THIS site & demonstration then! It makes it SO MUCH easier by actually showing each & ALL of the screws that need to come out,It tells you in GREAT detail step by step of everything you need to do so that nothing's ruined in the process! In the videos like when it comes to removing the keyboard/ribbon for it,you can't see what they're doing when removing the ribbon,which was my hardest part! I actually had it all put back together to learn it wasn't put back together right(since I wasn't exactly sure how it came off!) After 3 times,I FINALLY figured it out,by myself! So even this 1 doesn't say that the white clip that comes out 2 release the ribbon goes back UNDER the ribbon when putting it back! Cuz mine came out fast so I missed how it was even in there. Hopefully this helps someone since I SO wished I had this! Lol!
