Y700 15ISK Battery died after trying express charge

I bought my laptop in June in the US, but I'm currently living in France. My laptop worked normally in France, but on September 20th I activated the express charge function and the battery only charged to 63%. After that, I noticed that the battery doesn't charge at all, and that I have to work with my computer plugged in to the power outlet, otherwise it dies. Battery condition changed to Poor.

Before having this issue my laptop used to freeze a lot and I had to turn it off by pressing the power button, and that happened very frequently.  AFter the battery issue I also had some files deleted from my downloads folder.

Re: Y700 15ISK Battery died after trying express charge

Hi there, Diego-


Thank you for writing in to the Lenovo Forum - happy to have you here today.


Based from your findings, it's possible that:


- The battery circuit inside is not working to unload the charge, or

- One of the battery cells have already reached its life span

- the chip that handles how the battery gets charge/discharge and checks the charge level of each battery cell (both are controlled by a firmware) is malfunctioning.


Batteries degrade overtime due to heat and daily use.
