Repairing short circuit in laptop
mdijkens:
I have put in the new tantalum, but still no power.
I tried measuring as much as I can / understand, but I am not going to solve this :-[
The problem is in the initial path near the power-adapter. There's no power going to the charge-circuit and not to the laptop itself
I there anyone here who lives (or knows someone) in The Netherlands and wants to give it a try.
I am more then happy to pay 100 euro's if someone can fix this...

How can I test the mosfets?
Fuse? How to look for it?
I will measure the R005

This is the fastest but not very rigorous method.

This why I just |O when someone watching too much Louis Rossman comes around and complains about the cost of a laptop repair. Laptops are essentially not made to be repaired, at all. This is like a car where every service item is completely inaccessible until you strip the thing down to parts. And after "repairing it" there's often no way to even verify if you succeeded until most of those pieces are put back together. Most broken laptops should just go in the trash.

You're lucky, because many famous producers use glue instead of screws.
And in that case the expletives are unlimited.:rant:
