the cord isn't the same or the power adapter ( the brick ) isn't the same ?
Was your ex's computer the same as the one you're using ?
So I have an HP Envy, and I enjoy playing online games on it (CS:GO, Heroes of the Storm, and soon Battlefront). When my computer is not charging, it runs these games very smoothly, no lag at all. However, when I put my laptop on charge, it automatically gets slow. Lots of lag, I'll be behind the servers, and sometimes YouTube videos will load slowly as well. This charger cord isn't mine, it's my ex-girlfriends (in the breakup, we accidentally took each other's cords), but it still works due to the HP Smart Adapter feature. Could this be why? I'm looking to be able to play Battlefront for hours on end when it comes out Tuesday, so if I need to get a new cord, I will. I'd just prefer not to.
Thanks in advance,
