nop wrong i was cheking the chipset rom , the main spi bios is ok , she got 3.3 volts on pin 3 7 and 8
Do you have any chance to plug a full battery and try to power on then ?
Because you have similiar symptoms as I 've encountered before.
Remember, never ever connect two adapter pins together, it blows the charger chip. Use original HP charger.
also i dont get VCC +3.3S on the KB , also notice i should have on pin 33 of ITEkb , and ther eis no voltage there , as also there is no rsmrst as well ..i got some 3alw voltages on KB , but not main vcc
Which schematic are you using?
Did you check voltage at pin 8 of EC-BIOS?
im using hp_g62_compaq_cq62_foxconn_star_federer_rev_1.0_sch , cheked EC bios there is no voltage there only on sprom , for what i can manage and understand after cheking schematic is that there is some anomaly on s3 state , since some os the voltages that shouldbe present are not there, therefor kb will not work properly
im now trying to find out why i dont get 5 volts on main dc dc , and since i dont have that voltage i also dont get 5Val on the tsp51117 (1.5v ddr3 and outher smal voltages ) cheked that PQ762 should have on pin 3 voltage there due to RUN_on_load therefore i can't get as well any voltage for +3S , since i dont have this voltage i also can't have VCC on kb controler (should be +3S and its 0)
reprogramed u16 , (before i add changed the chip by another board i had here and nothing happen, even like this i reflashed the bios with the latest bios update , and the same , no DC jack led , and no 5 volts .

Check KBRST#_D voltage and 32KXCLKO/32KXCLKI frequency.
guys mine is working but there is no +VDD_CORE voltage on my motherboard, so no power at GPU chip, what is possibly causing that ? any help will be appreciated.
