Question: How to Recalibrate a Laptop Battery?


  • Fully charge your laptop battery.
  • Unplug your laptop from the power adapter and use your laptop as you normally would.
  • Drain your laptop's battery by keeping running several programs simultaneously. Do not plug your laptop into the power adapter even if you receive a low battery warning.
  • Use your laptop until it goes into sleep mode due to low battery charge. Then plug your laptop back into the power adapter and leave it connected until the battery is fully charged again.
