Hi there,
I have a HP Stream notebook pc11 the touchpad & cursor have stopped working after a clean & reboot of windows 10 from a usb stick. The device manager shows the PCI encryption/decryption controller has a yellow exclamation mark next to it, so I downloaded the recommended driver from HP website; Synaptics Touchpad driver filename SP71867.exe. I installed the driver from download & restarted the laptop, 5 times but still no joy. I've tried connecting a wired mouse but that hasn't worked either. Any ideas?
