I currently have an XPS 15 L521X laptop with a 512 GB SSD Hard Drive. I'd like to upgrade it to a 1 TB SSD HD. How do I find out the specs of the SSD drive so I know what requirements the new HD will need? Also, does anyone know where I can buy a larger SSD HD that will be compatible with this laptop?
Lastly, the laptop comes with a 65 WHr 9-cell Battery -- how do I know where I can buy a new battery with a longer life?
Thanks so much!
