HP Pavilion 15cs1065cl

[Ricky B 920]

I have a ho pavilion, model number in the title. It came with a m.2 with windows 10 pro installed. There is a spare slot inside the laptop for another drive. But the open ribbon cable sad hdd. Will an ssd work in that? I installed a 860 evo v-nand 500gb ssd with the proper ribbon cable L23889-001. Installed it reboot and I’m met with black screen, cannot enter bios and 5 quick blinks and four rapid from the caps lock. I reset the cmos ( windows key+b+power) and reboot everything works fine. I have files on the drive windows sees it in  device manager. But I have to rest cmos ever my time I reboot. Any ideas?

Hi Ricky B I have this exact same issue, I haven't tried resetting the Cmos yet, but I have the exact same computer and installing the exact same drive except mines a 1tb. I can't seem to get past the black screen, but once I unplug the SSD ribbon it boots right up. So have you figured out the issue? I bought the proper bracket and ribbon cable for the computer.
