I just dropped my computer for the first time and I'm really worried, its a Surface Pro 4 and I have not protection for it but I take the best care but my dog knocked it off the table and I'm hoping everything is working, it looks like the back stand is a little off it still works but it looks like it could be off a little. and my space bar does not have any lights under it and I am not sure if that is normal or not but I noticed it. My Main concern is that while I was testing my normal features and I was drawing using the pen and the screen flickered. I'm concerned and hoping that I can see if there is a program that can test all the features of my computer to test if anything Hardware wise could be broken or knocked out of place.
