Dear all,
i have this mobo which has the following.
19v rail is ok.
3.3 and 5v are missing.
the 3.3 and 5v ic's are not short. pins 8,9,15,16 (marked as SW)do not have any output on either chip.
On page 35 of schematic ic NB670 (3v) PC223 on NB670BST side i get 4.85v BUT on the other side of capacitor i get nothing. capacitor is not shorted. i di-solder PL22 and still the same results.
the same reading i got for NB669 (5v) PC234.
Thanks
