I have Fujitsu N532 napa rev.2.0 it has 3.3v on power butt on but after press does not start (button goes to 0v.
I have flashed the bios and replaced the kbc as it had noticeable dark heat type stain around one edge I cannot find either schematic or boardview.

Any help appreciated.

I have tried a couple of dumps still the same.
When I remove the cmos battery it boots automatically.

The power button works fine as you can shut it down when bios battery removed bu not power it up again.
The Bios an kbc are getting 3v .
Pm_rsmrst# is 3v with or without cmos battery
Cpu_vron is 0v and without battery 3v
p-rst 0v
pm_pwrok 3v
pm_pwrbtn is 3v and drops to 0v when pressed power button.
ac_in_oc 3.3v
wc_rst 0v
vsus_on 3v

Any help appreciated.
