Thanks Yogesh, no problem. With a bit of luck my next laptop 120 Watt (6A 20V DC) adapter repair will follow soon. I already replaced the power mosfet and now hope that only its controller chip is defect. I still am waiting on Aliexpress for that chip to arrive. But repair is a bit of a gamble this time because something had exploded on the solderside and inside. And I've got no clue what it was!

I got confused by those large numbers Parasuraman and stand corrected: One Billion is 1 Million x 1 Million in the UK (10^12) which is 1 Trillion in the USA. One Billion in the USA is 1000 Million.
One Dutch Biljoen is 1 Miljoen x 1 Miljoen (10^12 like in the UK).
I wrote 1 Billion equals a Million to the exponent 2 but that of course still needs to be (1 Million)^2 or still be multiplied by 10 for 1 USA Billion, or be written as (1 Million)^2 in USA for one Trillion. It shows how easy it is to confuse EXP with ^. 2EXP2= 200 and 2^2=4 (;)

Excellent article. It really explains very clearly, the repair of a laptop current adapter. I translated it into Spanish, and I posted it on my blog. https://reparandocosasdelhogar.blogspot.com/2018/02/reparacion-del-adaptador-de-corriente.html#.WoBomLPB9aS

Oops Albert, that module was only mentioned in my previous article. (I did 3 articles in a very short period of time which explains the mixup comment )

By-the-way: speaking about safety and about connecting to the AC power lines... be sure to here only use the n-channel mosfet SMK1060F variant. This kind of mosfet type TO-220F-3L is completely electrical insolated from having any galvanic contact with the Aluminium cooler plate after it is screwed onto it. They also sell this mosfet without the F in its name but they do not qualify to be used here!
