Calibrating your battery:

• Select Change when the computer sleeps.
• Set both “Turn off the display” and “Put the computer to sleep” to Never.
• Click Change advanced power settings.
• Expand the Battery section.
• Ensure that the Critical battery action is set to Hibernate.
• Adjust the Critical battery level percentage to be as low as possible.
• Apply the changes and save them.

Charge Your Battery:

• Charge your laptop’s battery to 100%.
• Leave it plugged in and allow the battery to cool down (this may take a few hours).

Discharge the Battery:

• Unplug your laptop.
• Use it until it shuts down and no longer turns on.
• If possible, avoid using the laptop during this discharge process.

Recharge the Battery:

• Immediately recharge the battery after it shuts down.
• Once fully charged, your battery should be recalibrated.

If you notice big jumps, it means the battery is not calibrated. Charge it to full and discharge the battery to 0% until there are no jumps and the battery is calibrated.
