( this scenario is somewhat difficult to believe since you also say " I always keep the AC adapter on my laptop plugged in." but heat cycling sometimes causes this.) OR the adapter itself has gone bad. so..... try a different adapter. BTW it is helpful if you give a "subject" whenever you post HTH and good luck----Venkat The NOSPIN Group has added a new feature on our website, web based bulletinboard for questions and answers: Visit our sister website at http://nospin.com
