If you have a HP, check the power cord head for the marking LS-15. If it has it, go to http://h30652.www3.hp.com/ to see if your cord needs replacing. HP will do it for free under a worldwide recall if you have a verified affected cord. The adaptor itself, is not the bit, but the cord. Potential fire hazard is the reason for the recall. Not all cords with LS-15 are affected.
That's what to look for. Then go through the steps to check it if you see LS-15.

"These AC power cords were shipped with products and accessories sold from September 2010 through June 2012. The AC power cords have the potential to overheat, posing a fire and burn hazard. Because these power cords pose a fire and burn hazard to customers, it is extremely important that they are validated on the program website. Customers should immediately cease use of the affected AC power cords."
That's from the general announcement page http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c04404446&lc=en
