Lenovo Y550P stopped charging battery
Check the Power Adapter and Outlet:
Ensure that the AC power adapter is securely connected to both your laptop and a functional power outlet.
If your laptop has an AC power indicator light, make sure it's illuminated. If not, try a different wall outlet (avoid using a power bar) .
Battery Charge Stops at 60%:
If your battery charge stops at 55%-60% and shows a "plugged in, not charging" message, it might be due to a power management setting.
Some Lenovo laptops have a feature that limits battery charging to extend battery life. To disable this:
For models with Lenovo Energy Management, Lenovo Power Manager, OneKey Optimizer, Lenovo Settings, or Lenovo Vantage:
Check if "Conservation Mode" is turned on. If so, turn it off.
If the issue persists, try updating your laptop's BIOS:
Go to the Lenovo support website, download the latest BIOS for your model, and install it.
Reboot your PC and check if the problem is resolved.
Hard Reset:
Sometimes a hard reset can help resolve charging issues:
Shut down your computer.
Remove the battery (if detachable).
Hold down the power button for 30 seconds (with the battery removed).
Reattach the battery, plug in the AC adapter, and turn on the computer. The battery should start charging .
If these steps don't solve the problem, there might be other causes.
