Business Notebooks

I am having multiple issues with my with HP EliteBook 865 16 inch G10. I have a HP 3 Yr Next Business Day Onsite Warranty for Notebooks that I purchased. I purchased this laptop in November of 2023 and yet in the HP Support Assistant it says my warranty expired in 2021! How can that be? What is going on here? The date on the Windows desktop is showing the correct date of 12/20/2024. I am running Windows 11 Pro 22H2. Is there an issue in the BIOS?

Also when I try to get Windows updates it says "Your version of Windows has reached the end of service."

Also I noticed when I shut the laptop down with PLENTY of battery left (60% or more) and a few weeks later when I go to turn on the laptop it won't turn on unless I plug it in! Once I get it running I see there was PLENTY of battery left, again 60% or more which should allow the Notebook to turn on WITHOUT plugging it in! What's going on here?

Even HP websites are an issue... When I tried to get to HP Support pages it routes me to various different HP foreign websites and yet I'm in the US. This is maddening! I purchased a sub $400 HP laptop in 2019 that never had issues. Having issues with an EliteBook that wasn't cheap is ridiculous!

What is the correct support phone number for my particular laptop? I can't get it because of the non English HP websites I'm being taken to. Thank you for the help!
