Toshiba Anna - 1197 the second level support (and supposedly the highest support I am allowed to speak with) Sent new laptop in for reaqpir as hard disk crashed, under mwarranty but told me the motherboard had a liquid on it and would cost me over $220 dollars even though nothing was every spilled on it and Toshiba.com, Internet

The Toshiba laptop was purchase in December 2011, in May it started to stop functioning as the hard drive would click and it would shut down, this happened when it was turned on and after a few reboots it would "click" and shut down immediately.  From previously working as a computer technician I knew this was probably a hard drive issue.  Borrowing a friends hard drive I was able to use the computer for days with no issue.  Called in to Toshiba and they said to send it in for repair.  Explained issue to them.  Week or so later they call me and tell me some liquid has been spilled on the keyboard and that will have to be repaired as well, I never spilled anything on the keyboard, once I wiped it with a basically dry cloth, but anyways they said that would have to be repaired for over $220 dollars before they could replace the hard drive which was covered by warranty.  Now I dont know what they did to the laptop but I told them just to replace the hard drive and send it back, ok they said but when I received it it was the broken hard drive still.  I am extremely angry and feel cheated and not sure what to do?  Take them to court?  Any help would be appreciated.  Thanks - John
