Not quite The consensus of posts seem to relate to a heat venting issue.
I’ve used some Office Depot aerosol to clean out the fan compartment and keyboard. It does seem pretty hot down there. I’ll also elevate the thing a bit. If that doesn’t work I’ll try some of the other referred solutions.
Once again, thank you all.
If the fan isn’t running at all, you have a serious problem with the fan motor or the thermal relay. If the fan starts running even faster when the video starts, a vacuum can pull out a lot of dust and this helps to cool things down. Also you may want to avoid running too many graphically intense applications at the same time.
If the fan just runs normally, then maybe it is not a thermal problem that is causing a shutdown, but rather a sign that your battery is going bad because the circuit protection is kicking in, which protects the laptop from drawing too much current. This is why I asked about when this happened in relation to your power source.
Do an overall tune up by cleaning up all the junk files and do a disk defrag and check for disk errors too. I had a laptop that was overheating because the hard drive was failing. Once I cloned the old drive to a new drive and installed it, the overheating went away.
Also if your heat sink has separated from the graphics chip, it could cause overheating and a premature failure of the chip. If you can’t solve the overheating problem on your own, you might want to take it to a shop. An overheating laptop has a short lifespan. Sometimes opening it up and reseating the heat sinks and cleaning out the dust will solve the problem entirely.
