Conceptd power plug slowly falls out of block socket. Thought I had charging problems, this normal?

I just recently got my conceptd and on the first day, I thought I had charging problems as the battery was slowly being drained and I had the plug in the wall and the laptop connected. I looked and saw that the power cord that connects to the wall was loose in the power block socket. I assumed that I must have not fully placed it in. I pushed the cord into the power socket and it started charging. Fast forward some 2 days and I notice that it wasn't charging again. I looked and saw that the cord was loose again from the socket. The problem is that it still looks like it's fully in the socket yet somehow it's loose. I wonder sometimes if certain people make the mistake of thinking that the laptop won't charge because of this weird loosening of the cord from the powerblock socket. It's not hanging from anything. I can only assume tempurature ? Well it's not too much of a problem but I was wondering if it was just me.
