My laptop is a HP Pavillion which I bought in early 2007. The battery always had a fairly short life but gradually stopped working altogether this year. I took it out and had been using my charger permanently since. The charger became a little dodgy in recent months and would sometimes lose power suddenly if I moved the laptop - causing me to think that the conection was a little loose. Last week it suddenly failed permanently. I bought a new charger and that worked no problem. I had it less than 24hrs when all of a sudden the power in the computer failed once again and the charger is no longer working (the little light on it no longer comes on) so I believe that perhaps the computer is causing the chargers to break perhaps?
