I have a gaming laptop that I mostly used as a desktop (bought used, was a good price) with external screen and devices attached. This past Sunday, I was wiping the dust off it and noticed that the trackpad felt oddly curved, then I also noticed that entire device body was slightly bloated as... which led to the discovery that the battery is swollen and that it needs to be replaced.

But I wouldn't have noticed it otherwise if I hadn't been cleaning my desk that day. It's placed on the far side of my desk on a laptop stand (although well ventilated) so I rarely pay attention to it, if at all. It might have gone on for much longer and eventually led to a disaster before I even caught on to the problem.

So, my question is: how does one track these potential hardware problems without having to manually inspect different parts of the device every now and then?

(While my device is a laptop with W10 OS, the question isn't limited to just that. Inputs for Mac and other related products are also welcomed.)
