Spectre 13 blocks third-party charger again

HP Recommended
Spectre 13
Microsoft Windows 10 (64-bit)

When I first purchased the new Spectre 13 last June, it blocks third party charger. Soon after, a new BIOS firmware upgrade (F.26.A I believe) removes that constraint, and I could use my Inergie USB-C 45W charger to charge the laptop while the laptop is power on.


recently, I notice that the laptop doesn't charge when its turned on and plugged with the Inergie charger. No problem when the charge is turned off, the charger will still charge the laptop.


Did somebody forget to put back that charging fix in the latest BIOS update?

Hi @meepoknang,


Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I came across your post and wanted to assist you.

I reviewed the post about charging issues with the unit. It charges only when the unit is turned off. I’ll be more than happy to assist you here.

At the outset, you’ve diagnosed the issue perfectly and performed great analysis of the situation before posting the query on HP forums.

Excellent job on that score. Kudos to you. It is always a privilege to work with technically savvy customers.

I take it as a privilege to share this platform with you. We value your relationship with HP and wish to serve you better.


It looks like a hardware issue with the unit. The battery controllers that supply charge to the battery are not functioning while the computer is powered on and work only when it is powered down.


For better clarity and to assist you better I would require more information regarding this.

  • Did it this begin after any update like windows update, bios update or any other update?
  • Could you provide me with the exact model of the notebook? If you are not sure how to find this information, please use this link:
  • Have you tried with a different battery or charger if you could get hold of one?

For now please follow these steps.

  • Uninstall the ACPI drivers from device manager for the battery.
  •  Then test and calibrate the battery.
  • Then change the power plan to the windows default plan.


Steps to uninstall the ACPI drivers

  • Right-Click on start button> click device manager> Batteries>then select the s drivers and right-click on it and uninstall all battery drivers.
  • Then restart the computer and check again.

Link for changing power plans:


I would also suggest here is to once again update the Bios and Chipset drivers on your PC from our HP support website, using this link.


Finally, try with a different battery and charger if possible by checking with a local Best Buy or Staples technician before buying it. If it works fine with a different battery, then you need to replace the battery and you are good to go. Same steps for the charger also.


Hope this helps.  Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great. 🙂  Please reach out for any issues and I'll be there to assist you. 🙂


To simply say thanks, please click the "Thumbs Up" button to give me a Kudos to appreciate my efforts to help.


 If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue to get it resolved without hassles. 🙂


Take care now and have a splendid week ahead.
