You mean 5V & 3V appear when you insert charger in dc jack but goes away after 5 seconds?? Right??

If so, thats perfectly ok as allmost all newer mb has 3V/5V rail as "Suspend". 3V LDO should be present all the time and i think its present as dc jack light keeps glowing. So nothing wrong here.

You can refer to HP Quanta Y11 diagram for IT8987E pinout. Have you flashed known good bios with clean me?? If not, request for same in "Bios Section" while posting your old dump.

If it doesnt help, then we'll proceed to measurement on KBC8987E for its basic requirement. But first flash bios.
