"Performance issues when connected to the charger.

[cristianpe]

"Hello, I bought a new HP laptop, and it’s presenting an issue. When it’s connected to the charger and the battery is below 100% charge, the performance drops for a few minutes. I’ve already updated the drivers and BIOS. Any solutions to this problem? Thanks in advance.

Hi @cristianpe,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are having issues with the battery. 

If your new HP laptop is experiencing performance drops when connected to the charger and the battery is below 100%, even after updating drivers and BIOS, here are some additional steps you can take to troubleshoot and address the issue:

1. Check Power Settings:

• Adjust Power Plan Settings:
  1. Go to Settings > System > Power & sleep.
  2. Click on Additional power settings.
  3. Select Change plan settings next to your current power plan.
  4. Click on Change advanced power settings.
  5. Expand the Processor power management section and set Minimum processor state to 5% for both On battery and Plugged in.
  6. Set System cooling policy to Active for both On battery and Plugged in.

2. Check Battery Health and Calibration:

Battery Report:

1. Open Command Prompt as an administrator.
2. Type powercfg /batteryreport and press Enter.
3. Check the generated report (usually saved as an HTML file) for battery health and performance details.

Battery Calibration:

1. Fully charge your laptop to 100%.
2. Let it discharge to 0% and shut down.
3. Recharge it to 100% again. This can help recalibrate the battery sensors.

3. Check for Thermal Throttling:

Monitor Temperatures:

1. Use tools like HWMonitor or Core Temp to check CPU and GPU temperatures.
2. If temperatures are high, ensure your laptop’s vents are clear and consider using a cooling pad.

Thermal Management:

1. Ensure that HP Support Assistant is up to date and check for any thermal management settings or updates.

4. Disable Battery Saving Features Temporarily:

• Battery Saving Mode:
  1. Go to Settings > System > Battery.
  2. Turn off battery-saving features and check if performance improves.
