I have these combination:
ThinkPad X220, 4286-CTO i7/USB3.0 model
ThinkPad UltraBase Series 3 P/N: 0A33932
Serial UltraBay Slim DVD MULTI IV P/N: 45N7451 (HL-GU10N)
I have encountered this problem:
When the DVD writer is in the Ultrabay and I init a system undock (Choose Eject Docking Station from system tray), the system freeze. Same when I press the button at left side of Ultrabase.
When DVD writer is in the Ultrabay and I slide the switch near Ultrabay, the system freezes.
If I turn on the "Power Off CDROM device when idle" in power management, the system freezes after some idle time.
Everything works fine when the Ultrabay is empty.
Is seems that everything points to the DVD writer, however the same DVD works well in X201 Ultrabase.
Can anybody help me?
