Windows 10: Why my computer charge does not stay in 100?

My computer charge to 100 percent but it does not stay to it and it get to 99 as soon as I unplugged the charger. My computer model is Dell 7400. Thanks for answers.

My Computer is Plugged in but not Charging

My laptop computer is plugged in but not charging. The power supply will maintain the charge level (%), but not add to it. Removing and reinserting the battery allows the power supply to add to the % charge to 100%.

Steps performed:

• Turning the computer off and restarting it returns the computer to the Plugged in, Not Charging state.
  
• Removing the battery again allows one complete charge, after which the laptop would no longer charge again.
  
• I have used more than one power supply with the same condition.
  

To resolve the issue, I remove the battery, obtain a complete charge, and maintain this charge by always keeping the power supply plugged in.

What is the root of the problem?

Battery status 100% fully charged

Every laptop and cell phone out there are designed to charge the battery to 100% and keep it there when plugged in. Modern Lithium Ion batteries do not have "memories" like the old Ni-Cads and others did. Once the battery is charged to 100%, the carging circuitry will trickle charge it to keep it at 100%. If you don't want your battery to stay at 100%, then you will have to unplug the laptop from power.
