Video Flapping (both DisplayPort and DVI-I)
on May 21, 2014
Thinkpad Yoga docked with a OneLink Pro dock.
When connected through either the DisplayPort or the DVI-I port, my display goes in/out of power save mode.
Problem surfaced during initial set up, but then didn't re-occur for a couple of weeks.
Then, a couple of weeks ago it re-occurred (sometimes it will stay on for an hour or two, but most of the time it's stuck in and endless-loop of (1) off for 5 seconds, (2) back on for a few seconds, (3) repeat
When it goes really crazy (constant on/off) my system will hang and require a cold reboot.
UPDATE: (June 5,2014)
Received a replacement dock from IBM. Initially, it appeared to have resolved the problem. However, after about a week (today) I noticed the exact OPPOSITE problem, when in Power Save mode, the monitor repeatedly enters power save mode (the "Entering Power Save" mode window pops up repeatedly.
I have never had such issues w/ any of our previous Thinkpad docking solutions, nor with the new company issued Dell laptop/dock.
I am not certain if the issue is with the dock, or with our new Thinkpad Yoga S1 (it's also had an intermittent issue)
Update: (June 13, 2014) Dock Issue; not resolved
