Hi @Pathakmansi 

Welcome to the HP Support Community.

Thank you for posting your query.

I Understand your concern about  the battery issue, don’t worry let me help you with this.

To better understand the issue, could you please provide a few more details?

• The exact HP laptop model number.
• How long the battery lasts before shutting down.

In the meantime, here are a few steps you can try:

• Run HP Hardware Diagnostics: Restart your laptop and press F2 repeatedly to access HP PC Hardware Diagnostics. Run the battery test to confirm its health status.
• Check BIOS Updates: Sometimes updating the BIOS can resolve battery communication issues. You can download the latest BIOS update from HP’s support website https://support.hp.com/  for your specific model.
• Perform a Hard Reset: Shut down the laptop, disconnect the charger, and hold the power button for about 15 seconds. Then reconnect and power on.
• Use HP Support Assistant: This tool can run diagnostics and provide tailored recommendations.
• Battery Calibration: HP provides a calibration process through HP Hardware Diagnostics or HP Support Assistant. Running this can help the system better estimate the remaining charge. (https://support.hp.com/us-en/document/ish_2268927-1713329-16 )
• Consider Replacement: Given the cycle count, the battery is likely nearing the end of its usable life. If calibration doesn’t improve performance, replacing the battery may be the most effective solution.

If the diagnostics confirm the battery is failing, replacement may be necessary.

Take care and have an amazing day!
