just purchased this K450 and i have a HDD dock (usb 3.0) as well as a Toshiba 3TB external backup drive (also USB 3.0)
if these are plugged in and i turn the computer on - the computer hangs at the LENOVO screen.
I did go into BIOS and set everything except the CD/DVD and the HDD as boot devices.
(SATA 1 hard drive is first, CD/DVD second)
that made no difference at all.
it is extremely irritating to have to reach behind the computer and unplug the external devices each time i either restart the computer or are starting it up from a off state.
I did see a similar complaint for another system in this forum and there was mention of a bios update to fix bug concerning usb 3.0 boot problems.
I looked and it doesn't appear that there were any bios updates for this system.
Please help - need to get this resolved
