It normally won't charge a battery that is mostly charged.  This prolongs the life of the battery.

It is not a good idea to charge a laptop battery to 100%, it damageing the cells and shorten the life of the battery.

A standard behaviour in the Thinkpad-series is charging when below 90% and stops at 96%. This start and stop-values can be modified in Lenovo Power Manager.

I have had this same problem with my P70.

 

If you have just upgraded, either explicitly or through a background process to Windows 10 Anniversary Edition, this seems to happen.

 

My cure: 

 

Shutdown, then remove all peripherals (including Lenovo docking station).  Remove Power Brick.  Reboot. 

 

Check to make sure to unset FASTBOOT  (Anniversary Edition seems to reset all kinds of settings).

 

Check all power settings that relate to charging threshold for batter (as described in previous posts).  Reset to charge always to 100%.

 

Reboot.  Computer should charge normally until battery is full.  Hopefully, problem will now be resolved.

 

Change charge threshold to a lower value, to preserve battery life.

 

Please let us know if this helps.
