hi SamYap,

 

There are findings that some of these systems (including the Z400) contain a function which can electrically disconnect the battery and a battery firmware fix was released to correct it.

 

See this article:

Ideapad Z400 or Z500 battery will not charge - plugged in not charging

 

I recommend you apply the fix ASAP and observe the battery status. If it still doesn't charge, try to perform a battery gauge reset under the Lenovo Energy Management tab and observe.

If the issue remains, I recommend you contact lenovo on how to go about replacing the battery.

 

 

Hope this helps

hi SamYap,

 

As the battery firmware fixes issues on how the battery gets charged, I recommend you give it a shot.

 

In an event that the battery firmware update tool doesn't resolve the issue then I recommend you contact lenovo support as a battery replacement might be necessary.

 

 

Regards
