Hi, Raksha      -

 

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.

 

You can also start by flushing out all static, remove battery and AC adaptor and hold down power button for about 15 seconds.

 

Try looking into Windows Power Settings and see if charging was disabled somehow.

 

Update us how it goes.

Re: 300-15ISK - Lenovo laptop battery drain

You have one of two issues. Either the battery has a defect or has reached end of life. Or the battery curcuit is defective and giving a incorrect detection of current battery capacity. In either case a tech needs to diagnose which problem it is and repair it.
