Hi @jxde,

Welcome to the HP Support Community.

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

I hear that your laptop battery is stuck at 100.

From the HP troubleshooting guidance, “Battery not recognised, not charging” symptoms include:
 

• No battery status light
   
• Blinking amber
   
• No boot without AC adapter
   
• HP also states that if the battery status light is off, the battery may not be recognised. If diagnostics report “no battery” or “unknown,” HP recommends using HP PC Hardware Diagnostics | HP® Support to verify battery recognition and condition. If the issue remains after reset steps and testing, HP guidance says to test with a verified working AC adapter and battery, and if it persists, the system board may need service.

What to do next:

Check whether the battery is physically recognised:
 

• If your model has a removable battery, reseat it and make sure it is installed properly with no gap or obstruction.
   
• Inspect battery connectors for visible damage.

Test with AC adapter connected:
 

• HP recommends confirming the AC adapter is working properly, because adapter issues can affect charging and battery detection.

Run HP PC Hardware Diagnostics (UEFI):
 

• Restart the notebook.
   
• Press Esc, then F2.
   
• Run the battery test and check whether it reports passed, weak, replace, no battery, or unknown.

If diagnostics still says battery not found:
 

• This strongly suggests either:
  
  
  • the battery is faulty / not being detected, or
     
  • the system board/battery connection has an issue.
     

I hope this will help.

 

Take care and have a good day.
