This Pentaxian had his DA* SDM died but which could not be revived after trying every known method including this. Coincidently, his wife was drying her hair using an electric hair-dryer. So, the desperate but annoyed user just got the hair dryer from his wife and blew vigorously to the SDM with hot air. But surprisingly, it was revived! :-o
Amazing and Amusing enough? ;-D
