Please go through it completely.
Please note that HP does not recommend upgrading either the operating system or the computer’s hardware as the components that were initially installed with the unit are certified by
HP for optimal performance. However, as you are very technically inclined, I would still request you to consult a local technician like Best Buy or Staples before proceeding to upgrade the unit.
Please ensure to contact a local Best Buy or Staples technician before the upgrade to ensure that it is correctly done and there are no compatibility issues.
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. 🙂
