Why not get the kbc datasheet from another schematic and start checking LPC pins on KBC. You can somehow check them with simple DMM. Dont give up without giving a hard fight.
@lapfix, with LPC readings ok and PLT_RST present-there are hardly any options left without schematics. BUFO_CPU_RST is something to watch for but not possible without boardview. So seems like end of story. May be someone else have any idea. Still do check the following:
01.UC5-pin8-9 for 1.8V & 13-14 for 1.0
02.UC6-pin6 for 1.0V
03.JU22 for VCC_GT
However, i do beleive all the test points above are having requisite voltage.
If NUmlock is not glowing on kbd, your mb is not posting. So do probe RAM circuit .PG present or not on RAM PWM?? As far as i remember, removing the two gpu coils make it UMA.
Yes PUM1 is RT8207P. Your measurements seems good. PG of ram ic is not used in this mb-i rechecked it as i've one repaired mb in hand-so sorry my mistake. Did you try converting it to UMA??
