My laptop keeps shutting off for no reason.

It's very possible it's overheating or shorting out. All laptops are basicaly the same inside and out .The components might change but that's it really. Go to the web site of your laptop, the manufactuers usualy have a guide as to how to open up their computer. Usualy you simply remove the plate above the keyboard, remove the keyboard this will expose anything that may need blowing out and such.
Try this link if your unsure how to get to your laptops manufactuer:

Good Luck,

thermal shutdown.... basically yes it's overheating and shutting down before the cpu gets damaged... check to make sure the fan(s) are going and you'll need to take it apart to get to the fans and clean the dust and dirt out.
