We have brand new (2 days old) SL400 . When we hook up to New USP 250410U Replicator mirror mode works. Switch to extended mode or off and it immediately shuts the laptop down and reboots. A blue screen message appears for an instant but can't read it.
We have another brand new system that works fine. Swapped the USB Replicator and same thing happens so it isn't the hardwarte. Lenovo was no help todat, they suggested we run the troubleshooting software.
We have removed and re-installed the software from provided dis - same results.
