I have an HP 15-d035dx.. Client had windows 8 on it, hated it and had Windows 7 Ultimate installed on it. Took it to Geeksquad for CMOS battery replacement and after wards the activation reversed. Tried same activation key, no luck. So, I installed Windows 7 Home Premium and activated it. Before doing so, I put all of the client's data on a USb drive. All the USB ports worked great. After install, none of them work. I installed the drivers from HP website, I tired doing the whole thing from device manager.
I'm at a loss.
