When I got my T520 yesterday, the dvd drive is automatically powered off when becomes idle for a while.
After I re-installed Windows 7 x64 this morning, and the dvd drive cannot be automatically powered off.
I have the latest power manager (and power manager driver) installed. I did some google search, it seems there should be an option that I can turn this feature on in/off the power manager.
The strange thing is the "system settings" under "power plans" tab in the thinkpad power manager only has 4 options instead of 6.

Thanks for your suggestion!
But that did not solve the problem.
In fact, after I unplugged my ac adapter, the dvd drive was automatically powered off. I then right clicked the icon of the dvd drive and clicked "power on", nothing happened. There is still no option to enable/disable this feature in the power manager in any situations I,ve encountered.
The only way I can power on the dvd drive is to reboot the computer.

I have the same issue; I do not have an option in Power Manger to turn the auto off feature on or off. The drive seems to lose power, the only way to eject the CD is to eject the drive or reboot. I also have an open case with Lenovo regarding this issue and I've gotten no where with Tech. support over the phone.

Install the newest AHCI driver then there will be the option in Power Manager.

Downloading the latest Intel Rapid Storage Driver and Lenovo's Power Manger 6 gave me the option to change the CD ROM drives' power state but, it didn't fix the issue. The drive is still powering off and the only way to eject is to reboot or use a paper clip to remove the CD.
