Excellent advice btb....if I may add... laptops played, on the lap, NEED let me repeat REQUIRE air circulation under the unit. Don't believe me look at those first degree burns on your thighs.lol... A cool-pad w/fans is a must. Cost around $40 bucks.
Another indicator or pre-lem of potential meter "demons" (spikes).. PC fan runs on and the unit gets hot (not warm HOT) feel the left side of your LT and you know what I mean. Stop your game (if you can) for a minute or two, lets the unit cool down. (catch up w/data)
For whatever it's worth just a couple of things that appears to lesson constant meter and/or game issues for me.
