New laptop showing incompatible power source detected

[JanetF-S7]

HP sent me a new charger and the error continues.  Best Buy Geek Squad suggested using a 90 watt charger.  Will this void my warranty?  I also need to send the replacement charger back to HP via Fed Ex.  What a PITA.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help,

Firstly, let's try this: 

• 1. Go to Start, search for Device Manager, and open this result.
• 2. Expand batteries.
• 3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.
• 4. Shut down the computer. 
• 5. Disconnect the charger.
• 6. Remove the battery. (only for removable battery)
• 7. Hold down the power button for 1 minute.
• 8. Insert the battery only. (only for removable battery)
• 9. Attempt to turn the battery on.

And, also I did go through Product Specifications and found out your computer shipped with 45 W Smart AC power adapter, using 90 W AC changer might damage battery. 
 

Hope this helps! Keep me posted for further assistance.
