if i dont get the 3v in vcc "pin8" were should i go ?

[@jobertgutierrez5788]

Hi do you have any idea where the bios vcc v3 is missing? I plugged the charger power supply and when i check the ec chip it has v3 but the bios pin 8 is v0.0
I also test while pluging in the power supply theres about v3.3 then after 1 second it will drop to v0.0.
Is my bios fried or it is just a corrupted bios. Thanks for helping
