I have a Lenovo T420 laptop. The reason I want to disable the CD-ROM is because when moving the laptop, I often unintentionally press the eject button, which turns on CD-ROM's power and pops the tray open - it's annoying for me. I am looking for a way to power off CD-ROM, and only power back on when I re-configure it, preferably done through the BIOS.
Answer
Disabling the effect of the eject button can be controlled at the OS level. Use CDRom-Lock or eject -i on to lock the drive closed.
