I just dropped my Lenovo z510 on the ground. It was on the bed, but it was connected to the charger, the cable of witch was on the ground. I stumbled over the cable, by which I pulled the whole laptop from the bed to the ground. The laptop now runs fine and luckily there are no flaws. However, I am concerned. If something happened by the hit, when are the consequences supposed to appear and show themselves? I am really dumb... Thank you.
