Are there no crashdumps in C:/Windows/Minidump directory? If there are, provide those for us.
Judging from the syslog, though, it doesn't look like there have actually been any BSODs, or at least nothing has been reported as an event, nor does it seem a crashdump has been made. To confirm we are indeed dealing with a BSOD and not some other form of crash, type "advanced system settings" in start menu, then go to Startup & Recovery, and make sure that the "Automatically restart" option is unchecked. Save changes then restart PC, then close the lid. If you open it back up and see a BSOD, report to us the contents. We'll need the bugcheck code (first number) and its subcodes (4 numbers in parentheses next to bugcheck code) and the name of any driver file it may list as possible cause.
If you do not get a BSOD, but your system restarts, then it means one of two things I can think of: you have a short in your laptop which occurs when the lid closes, or having the lid closed is overheating the system and causing it to automatically shut down. Either it's one of these or something else, but in any case, a problem like this can only occur by a hardware malfunction, which means getting out your warranty and coercing them to replace it for you.
