Have you tried contacting Amazon's customer service about this? Get them to either enforce the warranty or replace the laptop themselves.
Amazon has always been good with me but I am past the 30 day policy to return it them. Anyways it is Toshiba's reponsibility...
Amazon ‘sold‘ you that warranty, not Toshiba. Granted, it is a warranty, hence supposed to be directed at the manufacturer, not the merchant, but it still cannot hurt to ask Amazon – in the EU, you could go to them directly without a warranty from Toshiba and ask them to repair/replace it (up to two years after purchase), but customer law in Latin America likely varies.
