Hey, I'm currently working on a Chromebook.
Not turning on, no LED, power button= no reaction, USB-c charging cable plugged in shows 5V 0,00A.
While checking for shorts, I noticed 13 ohms to GND at a coil (5V rail).
I removed two resistors and the coil to locate the possible short. It turns out that the output of U43 drops from 143K to 13 ohms as soon it gets voltage on VCC.
VIN1 und VIN2: 12 V 3V3LDO: 3,3 V
BST: 3,3 V
EN and OUT 0 V
none of them less than 80 ohms except GND of course
That doesn't sound right to me. I hope someone...
9 results in 0.5701 seconds.
