HP 250 G3 15.6" Intel Core i3 Notebook

First time posting. Anyone have an idea whether the 320 GB drive is a HHD or SSD? Can the drive and RAM be upgraded without voiding the warranty?

Hard drive, not SSD. As these are open-box items, the warranty is a 30-day warranty from Woot and will not cover you upgrading it.

Thank you much!
