HP8740w power supplier question...

Hi All,



Just received my 8740w (WD941EA), very pleased. However I was amazed at the size and weight of the power supply. It is 19.5cm x 9.5cm x 4cm. Why is it so large. It still seems to charge the same size of battery as in my old HP nx8220 and its power supply is 1/3 size or not smaller. The weight is 1.2kg ! The number's are Rev:A01 0400676401 and on the bar code CT:WBGUC0ALLYW18D. It also has 230w on it. The socket is of the UK kettle kind, ie 3 wide prongs.



1) Why so large?



2) Is it possible to get smaller ones?



Thanks,



Sam
