Summary: if you plan on using this computer longer than a year. My computer is 3 weeks out of warranty.. purchased April 16, 2010. This morning when I attempted to boot up my computer the Lenovo screen came on and then went completely black with a blinking cursor in the top left corner. Lenovo refuses to fix my problem, except to pay 1/3 of the $500 dollars we've already paid to fix it. This process has been long and frustrating.
