Sounds like a hardware issue is forcing a shut down. It could be bad or lose memory or hard drive. You have taken the bad battery question out; as it still happens when plugged in. Depending on where you bought it they may take a look at it for you. It may be possible that something got loose during shipment. I would just ask them as you do not want to open it yourself and void a return or the warranty.
