The screws at the bottom of my laptop are loose
I can not find a small enough screw driver to tighten the bottom of my laptop, I am worryed that it will break along with the whole PC.
This reply is late but you need a Torx T5 screwdriver. I had to buy a T5-10 set from my hardware store just to get the T5. The bottom cover of your laptop doesn't serve any purpose except to cover up and protect expensive and delicate parts. You can just put tape over the screws to hold them from falling out as a temporary fix.
Just screw them back in. You can't really break anything
