I have a Lenovo Yoga 3 14, but it seems to be having some issues with power, here's what I've tried so far and the results.
1. Running with just battery:
Device powers on for about 15-20 seconds, can hear the internal workings going on, such as the fan, and then it suddenly shuts down. Nothing ever displayed on the screen.
2. Running with just battery plugged into TV with HDMI:
Same as before, except the TV shows Windows 10 booting up, it gets to the "Please Wait" screen just before Windows asks you to login, and then the laptop shuts down before it ever gets to the Windows login screen.
3. Running with Battery and Power adapter plugged in:
Identical to 1 and 2. Whenever the battery is in, the display NEVER works.
4. Running with Battery unplugged from the Motherboard and the Power adapter plugged in:
Display works on laptop, and the device runs reasonably smoothly, but still shuts down randomly sometimes, quite often when playing games, if I'm just messing around with word processing or internet browsing, it can last hours before it shuts down. Can withstand the Lenovo solution center testing (Full CPU and disk load) without powering down.
I'm at a loss as to what's wrong with it, I assumed it was a power problem, and the battery alone can't send enough power to run the display, whereas the AC power supplies more power, but it still shuts down randomly sometimes, and the laptop is on a solid desk, it's not caused by the laptop being moved and the power cable coming loose.
It is out of warranty.
Thanks, hope someone has a better idea as to what's wrong than I do!

Welcome to the Community Forums.
It would be best to have the machine checked with your local service center for possible power circuit issue.
Seems the battery contributes to the issue so the contact points and power board can be evaluated.
I would suggest to keep the battery out for now and take time to backup your files.
