Prakash, right behind the DC Jack you should find a fuse labeled F2 or FU, just slightly to the left of the power socket. It is a SMD component, use a multimeter to check for continuity. The fuse is a Littlefuse 429 Series and the datasheet is available [http://www.littelfuse.com/data/en/Data_Sheets/429.pdf|right here] and the fuse is available from places like mouser.com part number 5760429007. WR ML. Hope this helps, good luck.
