Check motherboard receives 19V. with a Multimeter measure voltages on coils, check for any components shorted to ground.  checked 3.3v/5v is up and running?

If you  have 3VALW And 5VALW at coil. 3VALW should go to sio and from there you should get 3v at power button. Check SIO for corrosion,shorting or any componenets which looks suspect. Check 3 & 5v SUS voltage.

    I have a Yoga 710-14IKB that will only turn on (cold start) when plugged in. Once turned on I can disconnect the AC and it continues to run and the battery charges fine. Restart on battery is also fine.

    If the laptop is switched off and i plug in the power cord the charging indicator LED will come on for a few seconds but then it turns off, i.e. it only charges when switched on.

    I did a quick check with a multi-meter and there is no 0v at VCC on pin 8 of what i believe is BIOS ROM (W25Q64FV) when switched off-battery only.

    Anyone have any ideas?

      Did you try to replace the battery yet? If it thinks the battery is too low when off with AC adapter disconnected, it won’t turn on (BATLOW# signal low going to the PCH for example).

        Yes both of the batteries I have exhibit the same problem.

        The 3.3, 5 and 1.05v are on with the AC but none with the battery alone.
