The battery charge stops at 55%-60% even with the AC adapter plugged in and shows a plugged in, not charging message. The battery cannot be fully charged.
Method One
Many systems support power management programs that can either extend the run time of the battery or extend the life of the battery. The 60% available (plugged in, not charging) message indicates that this sort of setting may be enabled. Under this setting, the battery does not charge to 100% when connected to an AC adapter in order to preserve the battery’s life.
Note:
If Conservation Mode is turned off and the AC adapter is added when the battery capacity drops from 100% but is still more than 95% (95% - 100%), the battery will not start charging. This is not a bug. It is due to the battery charge self-protection feature. This works by design.
Method Two
Go to Lenovo support website to download and install the latest BIOS. Reboot the PC and try again. If the problem persists, go to the next step.
Shut down the computer.
With the battery in (remove the AC adapter), attempt to turn on the computer by holding down the power button for 30 seconds. This should not turn on the computer.
Remove the battery (if the battery is not detachable, skip this step).
Again, attempt to turn on the computer (AC adapter is not plugged in) by holding down the power button for 30 seconds. This should not turn on the computer either.
Re-attach the battery, plug in the AC adapter, and turn on the computer. The battery should begin charging.
