If your HDD is recognized on another PC, I would say that the issue comes from the SATA connector of your laptop. If you have some warranty left, you should contact the reseller. Those objects that fell below keyboard might be the reason for the issue, but this should be confirmed from a technician. If you are going to return the laptop for some technical expertise, do a data backup before that.
