Hi @chevs,
Good Day. A warm welcome to the HP community. I reviewed the post regarding issues with the power button being on even after it is shut down.. I will be delighted to assist you here.
Superb description, brilliant troubleshooting and terrific observations made before posting. Kudos to you for that. 🙂
To assist you with accurate information I would require more information regarding this.
- Did this happen after a recent software or windows update?
- Did you perform a hard reset on the computer and check again?
For now please perform a hard reset on the computer from this link: http://support.hp.com/us-en/document/c01684768 Please select the country and follow the on-screen instruction sand check if it gets fixed.
If it continues, please update the bios, chipset and graphics drivers from this link: http://hp.com/drivers and check if it gets resolved.
Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, please. Please note that I am not overloading you with a lot of troubleshooting steps. Instead, just like you, I am eager to ensure that the problem gets resolved. So I am providing you with more resources and information at your disposal to deal with the situation better.
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. 🙂
