I am facing the below given 2 problems with the battery of a brand new lenovo U41-70 i5 Red model.
1. The plugged in but not charging error. Some suggestions in the web ask the user to remove the battery and change some stuff in the device drivers, but in my model the battery is not removable.
2. The battery dissipates a lot of charge while in complete switched off mode (not in sleep, nor hibernated). I have also disabled the windows fast boot mode from the power options, but doesn't work.
To give an estimate, in approximately 9 hours of shutdown (and the charging removed) the battery dissipates from a full 100 to 70%.
Note: I have updated the laptop which came with Windows 8.1 to Windows 10. Hence, the system is running on windows 10 now. The laptop is 10 days old.

Welcome to the Forums
As per the query we understood that you are facing issue with battery in your Lenovo U41-70 laptop.
Check with different battery and different adapter if available, check if there are any damage in the port, also try to uninstall the Microsoft ACPI and check for the issue. To uninstall go to device manager and select batteries option and select the drop down and select Microsoft ACPI control method battery option and right click and select uninstall.
Let us know the result.

I don't have a spare battery or a charger, so, I am unable to test that.
Otherwise, I had trying uninstalling the drivers etc. but didn't work.
Also, what is the solution for the battery discharging in the shut-down mode? Is it a faulty battery problem??

This is the error that I get while trying to update the BIOS. I guess the bios is already updated to this version?
