1) Remove ALL power. Remove the AC adapter (Charger), and Battery.
2) Suggest lay a soft Static Free cloth, on the table you're working on. Helps prevent scratching the table, and laptop.
Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise DO NOT mix them up.
You're going to remove the Top Cover. BEFORE this is removed you're going to need your ESD wrist str-ap on.
Electro Static Discharge
Your body carries Static electricity. Static WILL fry out, (Short Circuit), the delicate hardware components in a computer.
Wear an ESD wrist strap, have it's alligator clip attached to a good ground source; and your laptop is safe from Static.
Average cost is $3 to $6. Here is but one example,http://www.radioshack.com/product/index.jsp?productId=2103245
The Processor (CPU) is the MOST susceptible hardware component to Static Shock!
Don't wear an ESD wrist strap, and have it's alligator clip attached to a good ground source; and you can use your laptop for an expensive doorstop, or conversation piece. (Oh that? Yeah, Static got it")http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/laptop-disassembly-1.htm

Remove ALL power. Remove the AC adapter (Charger), and Battery.
Go to Step 1 and follow through to Step 17 on Page 3.
The Keyboard Bezel has to be removed,
Top Cover. (Palm Rest Cover),
plus the other components to facilitate removal of the above.
In Step 17 you see the Speakers. They are a large unit that can only be accessed for removal, after removing the Top Cover.
Look for a part number on them. It is a Toshiba part number.
Put Toshiba + part number, in your browser search bar, and look for replacements. (No -> + )http://www.discountedlaptopparts.com/toshiba-satellite-a205-left-and-right-speaker-set.html
Just for a point;
The above speakers look similar (To me), to the ones in the Irisvista link. (Pictorial disassembly guide)
Searching just now out of curiosity, I saw different styles shown, for the Satellite A205.
Point being I would want to see a PHOTO of what was being sold, to see if it is the right one. A lot of ads for Toshiba Satellite A205 speakers, didn't post a photo.
Could be different speaker examples for the different model numbers, of the model series.
(A205 is the Model Series. The number/letters after that designate the Model Number)
Seems that Toshiba STSA205 is the number, but you will know when you remove the speakers.
