Re: HP zbook 17 G3 T7V35ES - endless restarting pre-POST loop
Thanks for the info, I appreciate your help. for the moment I do not have the ec programmer but as soon as I can, I will buy one. As for the chip, it's a nuvoton ncpe586h, the same as in the diagram as the Probook 450 g3.

Re: HP zbook 17 G3 T7V35ES - endless restarting pre-POST loop
ok i understood, i have to reprogram the ec, it can't be the bq24780s charging chip which does not supply enough current to the ec. i looked everywhere for the firmware of the ec, and i don't found nothing.Leave a comment:

Re: HP zbook 17 G3 T7V35ES - endless restarting pre-POST loop
I think I found the problem thanks to the picture on the g3 light codes you posted.
Indeed it is the embedded controller which cannot launch the firmware, the first at the top of the list.
Do you think Mon2 there is a way to fix this....Leave a comment:

Re: HP ZBook 17 G3 wont boot
I forgot to tell you that the charging light comes on when you plug in the charger, the battery light flashes orange (even though I don't have the battery) and the power button LED lights up dimly.
I must also specify that I flashed the bios main and EC (no change)
I took the measurements of the coils, resistances and voltages,
PL7 13 Ohms
PL8 70 Ohm 0.9V
PL11 164 Ohms 0V (1.35V I guess)
PL33 34 Ohm 0V
PL37 0L 0V (charging coil)
PL39 0L 3.3V
PL40 0L 5V
PL42...Leave a comment:

Re: HP ZBook 17 G3 wont boot
yes of course, the motherboard is an APW70 LA-391p Rev 1c, no trace of liquid, all voltages are good, well I think.
the charger is a 200w hp, but I don't understand why I have 5v at the power button....Leave a comment:
