I had a problem with my vaio VGN-A130 laptop booting up (blue sreens).... took it to geek squad technicians and they told me my harddrive was going bad so it needs to be replaced and gave me a killer price. Then I thought I should do it myself by getting a software from Spotmau.com. I then carefully opened my laptop to locate my harddrive. After locating where it was I carefully put everything back together and press the power botton..... NOTHING no light.... no sound... Please somebody help me cause I tried to open it and put it back together again but it still does the same thing.... I never move that hard drive from where it is nor install anything else. What might have gone wrong?
