In a previous thread click here the recall was mentioned only stateside, according to another mag the recall is now worldwide for some models of their laptops (Latitude, Precision and Inspiron notebooks). The affected notebooks have power adapters by Delta, some of which have been over heating and in some cases catching fire.
Not all models will be affected, if you feel you may be affected and you wish to check you can visit this site click here or call Dell on 0870 010 3935 (the mag says you can call Dell free of charge, but I don't believe that is a freephone No.).
Hope this is of some help, and does not not cause undue worry.
