Hi @32149,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like your laptop might be experiencing an issue with its battery or power supply. Here are some steps you can take to diagnose and potentially fix the problem:

**1. Check the Battery Health

A. Inspect Battery Condition:

• If your laptop has a removable battery, turn off the laptop, unplug it, and remove the battery. Check for any signs of swelling or damage.

B. Reinsert or Replace Battery:

• Reinsert the battery and make sure it’s seated properly. If the battery is removable and old, consider replacing it with a new one.

**2. Power Reset

A. Perform a Hard Reset:

• With the laptop turned off and unplugged, remove the battery (if removable). Press and hold the power button for 15-30 seconds. Reinsert the battery, plug in the power cord, and try turning on the laptop.

B. Disconnect External Devices:

• Unplug all external devices (USB drives, external keyboards, etc.) and try powering on the laptop again.

**3. Check Power Adapter and Cable

A. Inspect Power Adapter:

• Ensure that the power adapter is firmly connected to both the laptop and the power outlet. Check for any visible damage to the adapter or cable.

B. Try a Different Outlet or Adapter:

• Plug the adapter into a different power outlet. If possible, use a different power adapter compatible with your laptop to see if that resolves the issue.

**4. BIOS/UEFI Battery Calibration

A. Access BIOS/UEFI Settings:

• Sometimes, accessing the BIOS/UEFI settings and performing a battery calibration can help. Restart your laptop and press the key to enter BIOS/UEFI (usually F2, F10, Esc, or Del, depending on your laptop).

B. Check Battery Settings:

• Look for any battery-related settings or calibration options. If available, follow the instructions to calibrate the battery.

**5. Check for Hardware Issues

A. Inspect Laptop Internals:

• If you’re comfortable, turn off the laptop and open it up (if it’s safe to do so). Check for loose connections or visible damage to internal components.

**6. Check for Blinking Lights

A. Consult the Manual:

• Refer to your laptop’s manual or manufacturer’s website to understand what the blinking lights indicate. Different blinking patterns can represent different issues.

B. Error Codes:

• If the blinking lights follow a specific pattern, it might be an error code indicating a specific problem. Look up the error code or contact support for more information.

I hope this helps.

Take care and have a good day.
