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?
