From your first picture i'm pretty sure those pin is 3V lcd.
but for the bios voltage that you say grounded i don't know if it save to inject voltage and search which part that short or no since bv or schematic not available...

yes i have 3.3v on mbdata, on Charging IC, ITE and battery connector. Pull up resistor not missing,both present on MBDATA and MBCLK. Both resistor 4.7Kohm from 3cvpu to to ITE. only missing MBCLK, no short when i remove pull up resistor, already try remove 2 sensor ic that connected to mbdata & mbclk but no luck, still missing mbclk. could it be bad ITE or EC firmware ?

I have question about MBCLK & MBDATA voltage, i got this board today. short 19v on tiny caps. Laptop turn on now but problem with charging, battery not detect, tried 2 good battery.
Then i measure all voltage on BQ24780S, what missing is MBCLK voltage, is this voltage appear/standby when battery or charger connected or after switch on ? BQ was replace 2 times and without success
Sorry for hijacking people thread, i think it's ok cause i got same board
Thanks
