If your HP Elitebook laptop consistently stops charging at 80%, it's likely due to a feature called "battery health management" which is designed to extend the lifespan of your battery by limiting the maximum charge level to around 80% - this is a normal behavior on many modern laptops, especially when plugged in for extended periods.
Here's why your laptop might be stopping at 80%:
- Battery Health Optimization: Most new laptops, including HP Elitebooks, have built-in settings to limit the battery charge to around 80% when plugged in for extended periods, helping to prevent battery degradation over time.
What you can do:
- Check your settings:
- HP Battery Check: Access your HP computer's settings and look for a "Battery Health" or "Optimized Charging" option. This setting usually allows you to adjust the maximum charge level.
- Windows Power Options: In Windows power settings, you may also find a "Battery Saver" option that can limit the maximum charge level.
