Inspiron 7559 doesn't boot after HDD upgrade

Hi everyone,

I want to exchange the HDD in my Inspiron 7559 with a normal SATA SSD (I have a Crucial MX300 750 GB).

I did that, and when I'm starting the PC now, the screen stays black, although the light on the power button turns on. To clarify, I can't enter the BIOS, I don't see the DELL logo, the screen just turns, and stays, black. After switching back to the original HDD, the system behaves normally.

First I figured that the laptop required some files on the HDD to start, so I reinstalled the original HDD and cloned it via the Crucial cloning software. That didn't help, the screen still stays perfectly black.

I tried detaching power-adapter and all USB devices, to no avail.

What can I do here? I don't want to keep using the original HDD until Amazon finally has my M.2 SSD in stock. I already updated the BIOS to 1.1.8, after which I was able to boot from the SSD ONCE, after the next reboot the problem was back.

I'd appreciate your help!
