Thank you for posting on HP Forums,
The Barachiel is at your service.
I understand you are in need of support, to get the information of upgrading the graphics card in the notebook. 🙂
I'll be glad to help you out, however, for an accurate solution I will need more details:
What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824
(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
Have you attempted any steps on your own before posting on the HP Forums?
If you could help me out with the exact product number of the notebook, I could dig around the manual for the same and provide you the exact upgrade information, If it is available. 😉
Please reply with the details for further assistance.
Eager to help!
I am an HP Employee
