Hi all, I have a problem with Acer E5-573G, mb: DA0ZRTMB6B0

Problem description:

Laptop after other service. Motherboard without bios chip - upload dump with clean me region and soldered chip - works fine. Next, I noriced a problem with battery charging - repaired. All works fine without touchpad.

FN+F7 checked.

Value on TP CON CN7

1. 3.3V +TPVDD
2. 0V TPCLK_R
3. 3.3V TPDATA_R
4. 0V GND
5. 3.3V I2C_TP_SDA_R
6. 3.3V I2C_TP_SCL_R
7. 0V TPD_INT#R
8. 3.3V TPD_EN_R

Checked resistance, resistors and wire TPCLK signal - all ok. Replaced KBC and touchpad - no change.

I found topic on vlab forum with same problem. One of the users write that it's problem with i2c tp address. Does anybody have this script from this topic?
