When you're given a laptop and warned that it gets a bit hot that's a thing.
Thankfully I didn't have anything that was not backed up on it when the Toshiba fried its wireless and got its ram bad. Shame was it was a pretty good laptop, but man it was a hot bugger.
Now I know why.
Moral of the story? Backup your files. Especially if your machine starts to act out of normal, strange noises, odd performance, getting hotter and hotter.
Keep your data safe.
