Hi everyone! I'm having next problem. I recently updated my Lenovo Z50-75 to Windows 10 Pro x64 and since the DVD is not working, it does'nt even appear in the units of This PC. When I go to the device manager it is listed like a recognized device but with no driver. I tried updating from the web but it does'nt find anything. The device is a PLDS DVD-RW DA8A5SH.
Can anyone please help me with this?? Many thanks.

Hi there! Many thanks for your fast reply.
I'm sorry to say that it did'nt work. I tried everything like you said but the problem is still there. Here is a pic of actual status: https://drive.google.com/open?id=0BzEeKDgoF_O2MzQ0M2gwc2w2bmc
Anything else that I may try?

Please try performing these steps
a. Press the Win + C and click on PC settings.
b. Switch over to the “Update & recovery” section.
c. Then click on the Recovery option on the left hand side.
d. Once selected, you will see an advanced startup section appear on the right hand side. You will need to click on the “Restart now” button.
e. Once your Computer has rebooted you will need to choose the Troubleshoot option.
f. Then head into Advanced options.
g. Then Startup Settings.
h. Since we are modifying boot time configuration settings, you will need to restart your computer one last time.
I. Here you will be given a list of startup settings that you can change. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.

Hi there! I've tried your instructions, but unfortunately it's still not working. After last instructions I've restarted the laptop and it was in same status. Tried to apply .reg file again and restarted, but still the same. Tried to uninstall the device and restarted, but still same issue. And tried again automatic searching of online drivers but did'nt find anything.

Have you run the Intel Chipset Tool/Utility for your machine. It should be in the downloads section.
Otherwise it should be found automatically on the SATA bus.

Sorry my Z70 has an Intel CPU so I figured it was similar, i guess not then but there should be some tool equivalent to that which detects all the hardware for device manager to access properly. I doubt its in the OS or correct.
All I can think of. It was working and I bet its detected in the bios so the OS is missing it because of this. Any other device not coming up properly? Sound, Camera, ports??

Yes, it was working just fine. This happend after updating to Win 10. Everything else is working with no problem. It is working and detected by BIOS, I can even boot from the DVD unit. It is Windows that is having some problem with it.
