Have had computer for 1 month, and power supply died. Amazon Customer service set up a conference call with Supplier (AST). Option 1 - return and replace...HOWEVER..supplier had none in stock and didn't know when they would..NOT AN OPTION. Option 2 - return and refund...HOWEVER...I had significant information on the computer that would be lost. Option 3 - local computer repair shop retrieve data and then return and refund (cost $110). Option 4 - local repair shop repair computer (replace power supply) (cost $160)...THIS IS THE OPTION I CHOSE, WHICH BASICALLY DOUBLED THE COST OF MY ORIGINAL PURCHASE. I'M NOT A HAPPY CUSTOMER!!
