There is play in the power cord of my Inspiron 660s computer.  You have to make sure it is centered just right, because it will not power on.  The power cord should not wiggle, it should fit snugly.  Does anyone know what the cause of this is?  The computer is a year old.  I have only moved it once or twice, out from under the desk.  I put in a new HDMI cord for my monitor.  When I moved the tower back into position there was no power.  I almost didn't get it to power back up.  I thought I had it in securely, and I powered it back up.  When I did, it must not have been in there just right, even though the plug was all the way in.  The power quit, and the computer went dead.  I had to readjust the power cord again.  I turned the computer on, but it would not boot.  Luckily I got it to boot of a a Macrium Reflect rescue cd.  Now I am worried.
