Stubborn screw

Hi, I need some advices on dealing with a screw on my laptop that seems to be blocked in it'a hole. Basically I can turn it effortlessly forever and it won't come out. It's impossible to tighten it either, it just keeps turning without budging whatever direction I try to screw it...

 

Here is what you can do.
Grab a pair of pliers and the proper screwdriver.
You are going to want to put the screwdriver in the head of the screw, and clamp the screw with the pliers.
Squeeze the pliers tight and at an angle of about 45 degrees.
You want to pull the screw up while loosening or tightening the screw.
You want to do this because by pulling the screw up the nut on the other end will be pulled up against the plastic or metal chassis, allowing you to tighten and loosen the screw.
Its a pain to do so get ready for some fun.

Is it possible to access the other end of the screw?

If it's counter sunk and can't get any purchase on it, you may need to drill it out, I wouldn't worry about it because the metal used to make them screws is weak and they're so small, it will take but a second or 2. That's why you threaded it, just make sure the bit is sharp/newish drill bit.
