incompatible power source detected

[Hardy_Potter]

Hello, since last 3 days, I faced a critical problem. My laptop's AC adapter is working while laptop is on shutdown condition, and when I start the laptop AC adapter is stop working and battery charging is stop. 2-3 times I have go through the diagnostic tests. But it shows AC adapter is incompatible. I don't know why it shows like that in power on mode while AC adapter is working in shutdown laptop.

Please help me to resolve it, If any body have a same problem right now.

Welcome to the HP support community.

I understand that you are getting incompatible power sources detected error, I am glad to assist you.

I have a few steps listed below that should help you resolve this concern: 

Unplug the charge and use the laptop until the battery drains to 15%. 

Turn off the laptop and turn it back on after 30mins. 

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager: 
1) In the search box, type and open “Device Manager”.  

2) Expand “Batteries”.  

3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.  

4) Click on “Uninstall”.  

5) At the prompt put a check in the box to remove the current driver  

6) Shutdown the computer.  

7) Remove the battery for minute and then put it back in.  

😎 When the computer comes back up it should automatically find the driver.  

9) Go to Device Manager.  

10) Expand Batteries.  

11) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there. 

12) Click "Search automatically for updated driver software"  

Do the same thing with Microsoft ACPI-Compliant Embedded Controller.  

Restart the computer and the issue should be fixed. 
 

Keep me posted.
