Hello, My son has a Dell Inspiron 15z and it fails to start up, The screen will not light up and we can't tell what is going on, It continues to beep 4 times with a small interval then starts again. I read this post http://en.community.dell.com/support-forums/laptop/f/3518/t/19498486.aspx and i've read that it says 4 beeps means memory read/ write failure. What i am trying figure out is how I fix this problem.
Thank you
