Sorry to hear that you have been having issues with the batter of the laptop. I would just like to ask, who did the upgrade to windows 10? If not mistaken, when the system was about to do the windows 10 upgrade, there would have been warning about programs/apps not compatible with windows 10. One of those app would have been the Lenovo Energy Management and you would have been advised to remove the app from the system. The model of your system is also not support for Windows 10.
Now I'm not really sure what happened to the system but it is surprising that the battery lasted for 3 years. It is common that after 2 years, you would have to replace the battery. If the system is still powering on please uninstall Lenovo Energy Management, and install Lenovo Settings. Check if the battery status is still good or not, and replace the battery if needed. The system might have overheated during the process so I would also recommend that you check if the fans are still running properly.
Here are the documentation/guide about the Windows 10 upgrade :
Hope this helps.
