Latitude 7490 i5-7300u black screen issue
When I try to turn the computer on, nothing seems to appear on the screen, usually there would be a Dell logo appearing but this time it just shows nothing at all. At first I suspected that the screen could be damaged, but when I do an LCD self-test (that is restarting the laptop and holding the "D" key while it's turning on), colors appear and it seems like the screen works just fine. The last thing I did before this issue was playing Minecraft and putting the laptop in sleep, several hours later I came back to the laptop being like this. Is this my fault? or is something wrong with my laptop that isn't my fault

Turns out I did not look up online resources enough, but I eventually found out that my laptop wasn't reaching POST. After fixing the issue (that is unplugging the USB stick of my mouse and turning the laptop back on), the laptop works like normal again. And I was mistaken by saying I put the laptop to sleep because I actually shut it down but didn't remember. Either way the problem is fully resolved.
