Did you buy your HP laptop/mini/netbook between 2010 & 2012?
Does your per pack have an LS-15 label on it?

Then you may need to change it immediately.

Due to safety concerns with chargers and power packs produced between 2010 and 2012, computer manufacturing giants Hewlett-Packard has rolled out an AC ADAPTER REPLACEMENT programme.

Please see below official communication from HP:


You are receiving this notice because HP has announced, in cooperation with various government regulatory agencies, a worldwide voluntary AC power cord recall programme. HP records show that you have registered a product that may be affected. The AC power cords have the potential to overheat, posing a fire and burn hazard to consumers.
The affected AC power cords were sold from September 2010 through June 2012 and distributed worldwide with HP and Compaq notebook and mini notebook computers (including mobile thin clients and mobile workstations), as well as with AC adapters provided with accessories such as docking stations.

HP’s primary concern is for your safety. To reduce the likelihood of damage from a power cord failure, stop using your power cord immediately until you have determined whether your power cord is affected.
