Solved Optical Drive not Working

[ksiu]

Hi,

My Thinkpad is running FreeBSD 12.2p4. The internal DVD player doesnot respond. I push the button on the DVD player, but it does not eject. I have to use a paper clip.

I do not see a /dev/cd...

$ ls /dev

dmesg also shows nothing for cd.

$ dmesg |grep cd

How do I make the DVD player work?

This really does not sound like a software issue. But for completeness, you could have a look at camcontrol devlist.

I push the button on the DVD player, but it does not eject. I have to use a paper clip.

It's not getting power. The eject button would work even if there's no driver attached to it. The camcontrol(8) output isn't showing anything either, which is to be expected if the unit is turned off.

How do I turn it ON? It is an internal DVD drive in a laptop. I looked thru the BIOS, and I dont see anything about DVD or CD drive.

If it doesn't get power (which is indeed the most likely problem here): Open your laptop and look for the cause…

You can of course try some other "live system" from a USB stick (e.g. some Linux) to verify first. I wouldn't expect a working drive that way though.

[rant]I hate the growing tendency of OSes to lock the drive door, just for "saving" the user from "trouble" if they decide to remove a disc.
This can lead to the drive staying locked until hard reset, some even need power cycling to get unlocked again.[/rant].
So I would just try turning off and on and then watch what dmesg says.

Okay. I took a second look at the BIOS. I look more carefully this time.
And, I see that under Security in the BIOS, the Optical Drive was disabled.
I must have disabled it awhile back (trying to reduce power consumption and battery life).

After I enable it. DVD drive is working now!
