Stress testing a laptop, what does this mean exactly?

Question

So, I've been having an issue with my hp laptop since around the time I got it, the screen will occasionally fade in dark and go back to normal within a second, either once and day or 3-4 times a day, it looks like the brightness goes down to it's lowest and then goes back to normal. I'm sending it in to hp for repair, for the third time, the previous two times before they did not really do anything to fix this issue with it, so now I'm sending it in again, where I was told that they will be keeping it for a few days and running stress tests on it to try to reproduce this issue it has, so they can try to figure out whats causing it and how to fix it, but what I want to know, is what exactly is a stress test and can this be bad for the laptop? Are they basically going to try to kill the computer to reproduce the issue? Cause to my knowledge, stress testing is where they pretty much push the hardware to go as far as it can go, correct me if Iam wrong.?

Answer 1

Stress testing is sorta like pushing a computer to its limits, it might also be that some websites you go on may be causing this. Or maybe the keys for the brightness are jacked up, something. What they're doing is tesing the laptops devices so they can see what might or might not be able to mess with the brightness.They won't kill your computer and if they do they'll have to send you a new one, so cheers on that part ^.^ Your laptop will be fine, they would call you/send you an email to tell you how it went, what was wrong, and if they could/help you fix it.
