Hi Everyone.. I am a totally newbie trying to fix laptops.

My first attempt, got the schematic here and boardview, really great for that thanks.

Hope you can help me understand all these thingys on the motherboard.

I found DT28 was totally burnt ( la-c361p ) and looking for a replacement. I ordered

hiden

and my notes said it was the SS16 however this was much bigger than others on the board. Dont know where my notes got SS16.

I searched RB751S40T1G_SOD523-2 again and find this datasheet

hiden

but I am confused by the measurements in section ' D ' says its 1.1 - 1.3 mm yet a same item on the board, I believe its a ' Schottky Diode ', see Im learning the jagon.. haha.. , is 5mm ( the black oblong only not including the pins. )

Is one of the other items in hiden what Im looking for or can someone point me in the right direction.

Many Thanks

Bill
