If your Lenovo battery is not charging, is it bad? Or is the issue with the A/C adapter or laptop itself? See the solutions below.
Steps To Fix Lenovo Battery Not Charging
To improve battery life, keep the OS and BIOS updated, and remember that the display consumes a lot of the battery life. Dim the screen to improve battery longevity. For batteries not charging properly see the steps below.
Why Is My Lenovo Laptop Plugged In But Not Charging?
A laptop that is plugged in but not charging can be caused by several issues.
- The first and easiest solution is to shut down the laptop, remove the A/C adapter and battery if possible. Press and hold the power button between 20 and 30 seconds. Replace the battery and A/C adapter and boot up the laptop. This procedure commonly fixes a battery not charging issue.
- The second solution if the battery is not charging while plugged in is to test if the A/C adapter is working or faulty. Unplug and then plug back in the A/C adapter. Does the laptop beep when you do this? It should detect the removal of the adapter.
Alternatively, if you have another similar laptop, plug the A/C adapter into it to check if it charges that battery.
Lastly, if you can remove the battery, do so. Then plug in only the A/C adapter and check if you can power on the laptop. This will tell you if the adapter works or not.
- The third solution is to check the battery power settings. Some laptops have battery maintenance options to either prolong the life of the battery or extend the run time of the laptop.
Check your power management settings, Lenovo Vantage and possible other battery applications to see if they are set to ‘Maximum Battery Life’ , ‘Conservation Mode ‘ or ‘Best Battery Health’. If so, the laptop optimizes for the longest battery lifespan and will/can prevent the battery from charging up to 100%.
Change the selection to optimize battery runtime if desired.
- The fourth solution is to check Lenovo’s support website for a BIOS update for your laptop. An updated BIOS fixes common issues and oftentimes will resolve battery problems.
