I have the same problem on my T520 where the OS just hangs and after couple of seconds shuts down. I made a thread earlier but nobody even bothered to answer...

ThinkPad T520 i5-2410M(2.3GHz), 4GB RAM, 500GB 7200rpm HD, 15.6in 1600x900 LCD, NVIDIA NVS 4200M 1GB

All,

If you are having this issue, I recommend running ThinkVantage System Update and windows Update. If problem persist, then try re-seating the rams. If that does not help, try running the laptop using only 1 RAM. This issue could be cause by faulty rams

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)
