In beta this only happened a few times when I was idle at the character select screen for a long time. Now it happens randomly while in the game for really no rhyme or reason that I can think of.

It still happens on the character select screen predictably and without fail. Looks like about 8 minutes on that screen will shut off my machine.

I've rolled back my graphic card drivers - no change.

I have a gaming laptop... this never happened before Rift.

Nvidia GeForce 9800M GT in an Alienware Laptop.

Can I get a response from tech support telling me whether this is a known issue? And of course - a fix???
