as far i havent 3.3va and 5va and 12va i looked the diagram and chip u6 got 19volt on pin 22, 19v on pin 5-6-7-8 of U16 and u20, but 0v on all other component. where i have to focus to find where the problem is? that chip circuit is a bit complicated to trace.

edit: u23 pin 4 is short. C264 is short both angles. so maybe c264 or u23 are bad...?

removed U23, still short. replaced it and removed c264 but still short on pin 4 of U23.

There is few probabilities C264 being in short, probably chip U6 or u23 would be the culprit.

removed c264 but still short, so i think problem is u6. bad thing is that if i order from china, i'll take 30-60 days to arrive..

changed u6 and now i have 3.3 and 5 volt cant make it run since one ribbon cable is damaged. ill get it in one week.

that fujitsu is really really bad assembled.... cable everywhere..... hard to connect....

And that was a happy end, i wish i could cee al treat with the same result,
there s a hope treat here that plp don't tell nothing more about the result,
it remains a mystery.

tnx for reply; i have to admit that this one was an easy fix

very few lapotop needed so small change to make them working again. lasta one was a macbook that need a fuse change; another one just psu replace
