I bought a Yoga 700 and after a couple of months it stopped charging and wouldn't turn on. When pressing the power button the light flashed amber a couple of times but that was it. I returned it for repair and the repair notes said the BIOS had been upgraded and it was working again. Unfortunately the person performing the repair sliced the top of the laptop with what looks to have been a Stanley knife but they didn't say anything. I returned it and got a replacement.
Now, a few weeks later I have exactly the same symptoms with the new Yoga 700. Is this a known problem with the 700 because it seems too much of a coincidence? I'm probably just going to ask for my money back unless someone can tell me a quick fix?
Any help would be greatly appreciated.

Hi celare ,
Would there be any battery indicator light showing ?
Try turning it on with the Novo button (item9 page 58 for Yoga 700 14ISK).
Update us how it goes.

Same issue with my Lenovo 700 11.6" . battery drained but now it won't charge, it wont turn on, and even the novo button isn't working. My 2 month old notebook is a paperweight!

Just a quick follow up. I bought a cheap compatible charger and my laptop started charging again. So in my case it was a broken charger that was the problem.

Hi all ,
The manual for the model have power checkout guidelines (page21) to isolate points of failure as described above. This would show steps to isolate the charger on the pins and likewise with the charger.
Thanks for getting back to our post as it would help others having the same issue .

We had the same problem - no lights, no charging, no boot up - with our Lenova Yoga 700 11. The problem was solved via chat with the Lenovo people through their website.
This is what we did, the tech called it a powerdrain and she said she uses it as preventive maintenance by doing it once a week. She didn't think it was a problem to do it more frequently, but not necessary.
Here is what you do:
- Remove all external devices.
- Unplug the ac adapter (charger)
- Hold the power button down for at least 10 seconds.
- Reconnect the ac adapter and try turning it on.
It booted right up for us. She also mentioned something that wasn't quite clear - that the problem was caused by a windows update somehow, or to quote her somewhat mangled syntax "That happens when system is freezing up due to some loaded Windows update."

I wanted to add some more to this series of comments. I have the Lenovo Yoga 700 11-ISK and suddenly out of the blue the battery would not charge after 2 years of normal working. I did recently have to perform a 'windows' back-up, owing to an issue we had with Office365 not re-installing properly. I'm not sure if this triggered the battery issue or not. Either way, the battery simply would not charge.
I read lots of reviews online about how to fix the problem, including above, but none of these worked (ie turning off laptop, pressing power button for X seconds etc). In the end the battery ran completely dead, at which point the laptop would not even turn on. Even worse, even if the power cable was plugged in the laptop still would not work.
In the end, I decided that I would try one idea I had seen posted elsewhere about disconnecting the battery.....quite tricky given that the laptop does not have a removeable battery. The reason I am posting this, is because it worked, and the fix was actually pretty simple.
This is the user guide for the laptop:
Before you start though you need a set of precision screwdrivers. I bought this off amazon for £6:
On page 32 of the user manual (page numbered as 32, which is the 36th page of the pdf) there is the instruction for removing the back cover of the laptop, you'll need a torx head screwdriver to do this. 9 out of the 10 screws came out easily. The tenth annoyingly was cross-threaded slightly, but by pressing a little more firmly I was still able to remove it. With all the screws out the back cover simply 'pops' off.
At this point you need to go to page 34. Note: I did not need to remove the battery. I only needed to disconnect the battery (unplug the battery connector  on the instructions on page 34). It was a little stiff, and you need to be a little careful to ease it out with your finger nails, but the connector does slide out as per the diagram.
With the battery disconnected I plugged the USB charging cable into the charging point of the laptop (with the back still off). I then slightly opened the laptop and pressed the power button to see if it would turn on; it did. I then closed the laptop again. Then I removed the charging lead.
At this point I simply re-connect the battery (whilst unplugged). Next I plugged the charging cable back in, and waited to see if the charging light would turn on. Thankfully it did. I then left the back of the laptop up whilst it was charging, just to make sure that it was charging properly. It soon became clear that it was, at which point I simply put the back cover back on, and screwed in the screws again.
Now it is working fine again.
I am not that technical and wanted to document what I did as whilst it was a pain in the backside, it was not difficult.
