T460p hangs on boot after BIOS update from 2.17 to 2.18

2017-09-04, 18:38 PM

I have a Dell U2415 monitor, which has an integrated USB3 hub. When that hub is connected to the TP at power on, the TP gets stuck at boot screen, when the message "To interrupt normal startup, press Enter" displays (and the Enter key does not work in that state). Note:

  • When I unplug the USB3 cable that goes to the hub, the TP continues booting correctly after some seconds.
  • When I start the TP without connecting the USB3 cable, the TP boots correctly.
  • I reset BIOS to "setup defaults" -> no help
  • With the previous 2.17 BIOS, there were no problems. Haven't done BIOS downgrade yet, as Lenovo says 2.18 is an urgent upgrade.

We are aware of this issue and working on a fix, but as of now I don't know a schedule.  Same issue is also reported on T460s.  Sorry for this trouble!
