Replacing the screen hinges on the Toshiba Satellite A10, A15, and Tecra A1 series laptops is just like replacing the screen hinges on any other laptop - with the EXCEPTION of the left and right speaker cover grills that stand in the way. This part is unique and you won't see it duplicated anywhere else. So ... this piece is here to help you get the speaker cover grills outta the way safely and without fuss.
(1) First, you have to separate the top case from the bottom case, then, remove the screen. Then turn the whole top assembly over so you'd be looking down at the bottom of the palmrest.
(2) remove the F5 screws holding the left and right speakers in place and move the speakers out of the way - now you can see the lower portions of the hinges - then remove any black tape or sticky foil that cover over the portion of the hinges that were underneath the two speakers. But before you can remove the hinges, you'll first have to get the speaker cover grills out of the way.
(3) The speaker cover grills on the Satellite A10, A15, and Tecra A1 models are all the same: they have legs on 4 corners that are bent down to secure them to the casing. 3 of the 4 legs are clearly visible and can be straightened out easily while the 4th leg is buried and is just nigh impossible to get to. So ... straighten out the 3 legs of your speaker cover grill (the 3 that you can get to) , push it out so that the 3 straightened legs are completely free of the casing, then grip the speaker cover grill, pull it away from the casing, and keep wiggling while you're pulling it away from the casing - and the 4th leg will eventually be loosened to the point where it can be straightened out and the darn thing will come free. And that's it. It usually takes 30 seconds to a minute's worth of wiggling. I called this the "shake your booty" technique - it's unique to the A10, A15, and A1 laptops and you won't have to do this anywhere else.
After you've removed the speaker cover grills, immediately use a pair of pliers and straighten out all 4 legs - that'll make it much easier to install them back after the hinges have been replaced.
Now that the speaker cover grills are out of the way, it's just like ... replacing the hinges on any other computer. If you have a digital camera, use it to take a snapshot of the hinges before you remove any screws, as this will help enormously later on when you put the pieces together. And one last thing: on the A10, A15, A1 laptops (and some other Toshiba laptops), each hinge is connected to the top lid via 3 screws - two are obvious but there's also one additonal screw that goes in from the bottom (directly above the left / right speaker) - that's the one that you'll miss if you ain't aware of its presence.
That's it, guys and gals. You won't learn this anywhere else. Now ... everybody, get on the floor, and let's dance .... don't fight.... your feelings ... give yourself a chance ... shake shake shake.... shake shake shake ... shake your booty .... shake your booty ....
