Two days ago I was using my Yoga 3 14 80JH. I stopped using it so I closed the lid and the session was suspended. After a few minutes I wanted to use it again and it didn't work: the pilot that indicates if power is supplied and the charge of the battery (by color and blink frequency) didn't work with nor without the power wire being connected, the boot button didn't work either.
So I started reading through the internet and I found somebody had the same or a similar problem and was able to fix it by opening the laptop, disconnecting the battery for a few minutes and connecting it again, together with some use of the boot button and the power wire. Since my laptop is out of warranty, I decided to try it. However, without the proper tools, I was able to remove only 8 of the 11 screws. I spend almost an hour searching through the internet how to fix the problem and trying to remove the screws. When I realized I couldn't, I tried to boot the laptop again and it worked! So I thought the problem was solved.
Yesterday morning I was working with the laptop and no problem. But I decided to run a battery calibration since the laptop asked for it and, from my findings in the internet, it seemed the day-before problem was related to the battery. So in the afternoon I started the battery calibration. After about 5 hours, I had seen that battery charge had varied from about 70% to 100% to 14% and finally to 60% and stabilized (I wasn't monitoring the process, but the few times I checked the charge had these values). So I thought the battery calibration had finished. But, since it didn't show a message, I decided to leave it all the night and this morning was shut down. The power-battery pilot was on, however, and white so I assume power supplying and enough battery. I pushed the boot button and nothing happened exept the pilot in the button was on for a few seconds. Then I unplugged the power wire and tried again: both the battery and the button pilots were on for a few seconds and that's all. I tried to press and mantain the boot button down. With the wire plugged, the button pilot was on for a few seconds and the power-battery pilot blinked every few seconds. With the power wire unplugged, only the button pilot was on for a few seconds.
Can anybody please help my? Should I do something with the battery? Thank you very much in advance.

Thank you very much Jwes!
So, before calling these numbers, I opened the laptop and tried the "disconnecting the battry" but it didn't work either.
I even took the motherboard out (very carefully and previously disconnecting everything that was attached to it) to take a look in case something was (or seem to be because I don't have formation in informatics nor electronics) broken or molten. But I wasn't able to identify any case.
Then I called the numbers you proposed. One of them only works with the Professional devices, which is not my case. The other one asked me to do again the different button tests and it didn't work. So theye proposed me to send the laptop there (I live in Valencia and their office is in Madrid, the only one in all Spain). They would diagnose and tell me what they think is happening and how much it would cost. If I agree, the do it and I pay. If I don't agree, they send the laptop back and I have to pay 35 euros. In any case I have to pay the Valencia-Madrid trip. Also talking with them, they said high probably is a motherboard problem. So I said "yes, that's what I think too after reading through the internet, but a motherboard has a lot of components and it should be a waste/pitty to replace the whole board when possibly it is only one component that is malfunctioning". And they said that, if it's a motherboard issue, they replace the whole board independently of what the problem is.
So I'm thinking of doing it myself since it's really easy and I think I can get a better price. But the problem is knowing where to buy the motherboard. I've seen different models from around 145 dollars to almost 400. Always with i7 processor. The laptop costed around 1000 dollars four years ago and know it's around 500 dollars.
What do you guys think? Any advices? Thanks!
