Hello Guys .... How should i deal with a 3.3VALW power rail that have a 40 ohm resistance ... i removed the jumper and i found that this low resistance came from after the side of the components that will get the 3.3 v not the IC one ... 3.3VALW coil have normal resistance ... i injected 3.3V on the rail and i get 0.1A Current ... this laptop have some water damage but when it came it has not this problem this problem happened with me after desoldering and soldering the ic of 3/5V ... |

USB Data pins all are good (0.500 on Diode mode) beside one ... 30 Ohm resistance to ground +SOC_VNN = 4 Ohm resistance +SOC_VCC = 25 Ohm REsistance |
