Hi all,
Mainboard model: BTUU1 NM-A381 REV: 1.0
i have an lenovo yoga 3.14 (80jh) laptop and will not power on or charge, measured the battery voltage 0.00v dead flat.
i managed to charged the battery, placed the battery back into the laptop and powered up.
checked for shorts, checked mosfets, fuses and caps around battery and input not see anything, ive missed something.
i wasn't getting negotiating voltage 19v only 5v. so i replaced the pu101 (BQ24715RGRR), once replaced i was getting negotiating voltage 19v but blinking white light 3sec...
