Cannot complete battery calibration.

[Wallby]

The HP support assistant keeps having this notification. I've tried to run the battery calibration procedure twice, and both times when it was far discharged (the second time at 6%, as I was watching, but I wasn't the first time) the laptop just turned off. And pressing the on button again, selecting the test again, it started at 1/6 again. Am I not supposed to turn the laptop on? Will it do that automatically? It's unclear.

Hi @Wallby,

Thank you for the details.

To fix the calibration issue on your HP Pavilion Plus, discharge the battery completely while in the BIOS/Diagnostics screen (F2 at startup) to avoid OS interference, and then charge to 100% uninterrupted while off. If it shuts down at 6% or higher, the battery is likely weak or miscalibrated and needs to be fully depleted to 0% to reset. 

• Do Not Turn On Windows: Run the battery test from the BIOS/Diagnostics menu. Turn the laptop on and immediately press F2 (or Esc -> F2).
• Initial Charge: Ensure the battery is at 100%.
• Deep Discharge: Disconnect the AC adapter and let the laptop run (inside BIOS) until it turns off completely. This allows the battery to reach 0%.
• Recharge: With the laptop off, plug the charger in and leave it to charge to 100% (takes ~3+ hours).
• Repeat: It may take 2-3 cycles of this process for the HP Support Assistant to recognize the calibration. 

If Calibration Fails Again:

• Battery Degradation: If the laptop keeps shutting down far above 0%, your battery might be failing and needs to be replaced, especially if you get a "Replace" or "Failure ID" message during tests.
• Clear Alerts: If the battery runs fine but the alert persists, try upgrading the HP Support Assistant, as it might be a false positive. 

For many newer models, the calibration must be done while the computer is turned off to work effectively. 

I hope this helps.

Take care and have an amazing day ahead! 🚀
