I am now having the exact same problem.
Note there is another topic with this issue, and no Lenovo staff have opined there:

Amy_Lenovo has provided a number of things to check - quite rightly.
However, her list is almost exclusively about hardware topics; most of these on the external power side.
The Lenovo team seems still after amny weeks in denial about the most likely cause - Lenovo software. OKO is the most likely culprit here.
Any other views?

I called tech support about the issue. After several steps, they deemed it necessary to replace the battery. I have a new battery now and the problem has gone away. The real question though is whether the problem was actually the battery, or the cable connection as discussed by others.
Such high hopes with this laptop, yet I wish now that I had never bought it! As soon as a lightweight Broadwell U ultrabook is available, I will get that and try to sell the yoga 3 pro while it retains some value.

Since I have a question not related but not limited to battery, as this is one thread where Lenovo staff are providing technical assistance, I would like to post my question here. My brand new Yoga Pro 3 (less than a week), laptop number 4 (in a month) has not switched on twice with battery stand alone. Only where the ac adapter is plugged in does it start. Could this be a battery problem?
Would appreciate the advice.

I thought I would share some learnings with my charger, and see if your experiences are the same.
My charger was not charging the Y3P at all. After doing some testing, I isolated the issue down to the power brick. The issue was that there was some play on the prongs that prevented the circuit from being complete. Applying some soft pressure to the brick to slightly angle it in the wall would cause the charger to work.
If you can, check to see how much rotary play there is on the prongs in the brick. If it doesn't feel firm, this may be the issue.
All I know is that the Y3P requires a solid connection in order to establish the handshaking to get 20V into the unit. In my scenario, the brick had too much play, and the connection wasn't consistent until I bent the brick as much as 10 degrees once plugged into the recepticle (DEFINITELY NOT RECOMMENDED).

I have a version of the intermittently will not charge issue. I have pinpointed the issue, but not gotten a solution.
In my case, the issue is the power adapter, specifically the flip-out prongs for 110AC. The internal connection of these prongs inside the power adapter block are flaky. They are loose and will only make a connection in one specific position. If any wiggle is done on them, they will loose connection and stop charging. It is so bad that it will not work plugged into any wall outlet. I've gotten it to work on an outlet that is horizontal, on the floor, or by plugging in an extension cord, so there is no gravitational pull on the prongs.
I purchased the unit at Best Buy, and they would not replace the power cord, even though under warrantee and with an extended service contract..... go figure.

A BIOS to improve charging is in the works and will hopefully be released by the end of May.
I am still looking for assistance with adapters that have loose prongs. If you are able to help, please message me.

Amy, today I plugged my Y3P into charge and it isn't charging. It says my battery is good and it is charging but it is staying at 0%. Is this the problem that the BIOS update is going to correct?
Untill then I guess I'll just have to leave it in when I'm using it.
