Re: PM_I_hpc_s mv_mb_v3

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

Re: PM_I_hpc_s mv_mb_v3

Excuse me for asking is EC bios different from KBC bios? Thanks

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.

Re: PM_I_hpc_s mv_mb_v3

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?

Re: PM_I_hpc_s mv_mb_v3

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)

Re: PM_I_hpc_s mv_mb_v3

EC bios , 0.39 volts
poin 3 , 7 and 8

spi rom
~
3:30 on pin 3 7 and 8

I can't tell how I sure about that charger chip.

You should check +V3.3A at pin 8 of UI6. (EC SPI ROM)
Also check EC_ALW_EN and PWR_SWIN# signals are both working properly.

Re: PM_I_hpc_s mv_mb_v3

like i mentioned before , spi rom , got 3.30 volts on pin 3 , 7 and 8

for EC_alw_en got 0 volts
for PWR_SWIN got 3.29 volts

for EC_alw_en got 0 volts

Then, reprogram UI6.

Re: PM_I_hpc_s mv_mb_v3

ok , i will reprogram the bios with the latest version i'll find in the website of hp and i let you know

EC-bios is the same as kbc bios. (UI6, page 25)

PCH-bios (or main bios) is US2. (page 13)

Some motherboards have the code of EC-bios integrated in the PCH-bios, so only one bios chip is needed. It is connected to intel PCH chip.

Re: PM_I_hpc_s mv_mb_v3

Thank you very much Francisco, I really appreciate it

Re: PM_I_hpc_s mv_mb_v3

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.

Re: PM_I_hpc_s mv_mb_v3

Check RSMRST# if 3.3v is present.

But the lack of 5v is also a concern. You must fix this first.

Re: PM_I_hpc_s mv_mb_v3

rsmrst = 3.30 volts .

not having 5 volts is what is driving me nuts , could this be like powersaver issue ? since there is no short on the god dam line rail ....

What do you get at pin 7 and pin 27 of PU850?

Re: PM_I_hpc_s mv_mb_v3

Just laughing and reminding u the charger chip again

Re: PM_I_hpc_s mv_mb_v3

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.
