T420 hl-dt-st dvdram gt50n

I see a little icon on the bottom right of my screen indicating that this device (hl-dt-st dvdram gt50n) is connected to my laptop. I'm guessing this is the CD drive because when I ejected it and opened My Computer, I see that the CD drive icon is not there anymore. I didn't have this problem before, the CD drive being "powered off," but now it's just gone. When I restart my laptop, I see the little icon on the bottom right again. Anyone know what's going on?

 

In Power Manager, do you have enabled the settings for automatically powering off the ODD when not in use? If so, try disabling those settings.

 

I can't seem to find the setting for that.

 

I would try the CD/DVD uppper/lower filters fix or manually deleting the keys yourself, but be for-warned modifying your registry can hose your OS, so always back it up.

If you want to manually delete them, run regedit, go to HKEY_LOCAL_MACHINE then SYSTEM, then CurrentControlSet, Control, Class, then {4D36E965-E325-11CE-BFC1-08002BE10318}, and delete the upper and lower filter registry values if they are there and reboot your machine.
