Hi everyone, I know I can't really get solid knowledge on this but I'd like anyone's input or prediction...Well, I've had to return my T4210 3 times. The first time was to replace the screen and the other 2 times were attempts to fix a random continuous blue-screen problem (which is still not fixed). On the second send-back they replaced the hard drive and the third time they replaced the hard drive (again) and the system board. I don't know why they haven't tried replacing the memory, but anyway...do you think there's any chance I could send in my faulty T4210 for the T4215? I'm just tired of this whole system and continuous problems. I'd love any input or suggestions.
