X200 w/ Ultrabase on Win7. Worked fine this morning. Disconnected x200 from docking station properly this morning and hibernated, as usual. Returned, dropped x200 into docking station:
- external mouse
- external keyboard
- docking station speakers
AND - on the left side of the docking station, where the un-dock lever is, all three lights are lit: green arrow left of undock button, green arrow right of undock button and red stop indicator right of undock button.
I've performed a variety of reset functions: restarted, shutdown, unplugged keyboard/mouse [they work when plugged directly into x200] - all to no avail.
I've just seen that a BIOS upate came out in December 2010, so I'm off to upgrade that, but really can't see that it would cause this freakout. HELP!
Updated BIOS [3.17] - no change.
Further details: -apparently the docking station is simply not supplying power to the ports since --no lights on keyboard --cd drive not functioning
Apparently it is a power issue. Passthrough ports [monitor] work fine, but those requiring power do not. I removed the battery from the X200 then docked to ultrabase - booted up and all peripherals work. What causes such a problem?
