Got a bit of an answer via google:
"A Lenovo X260 not powering on with a USB KVM attached is likely due to
a power-on conflict caused by the USB device drawing power or signaling
the machine,"
There may be a bios setting:
"*BIOS Configuration:* If the laptop boots without the KVM, enter the
BIOS (F12 or Enter at startup) and look for USB settings, such as
enabling "USB BIOS Support" or reducing USB power consumption during boot"
my 140x and 240x don't have this behavior. Maybe they came with USB
BIOS set right....

I have my 260x on port 3 of my KVM. Well, probably does not matter
which port...
I power on, the key lights come on and go off and nothing.
I hold down the power button until it shuts off. Unplug USB (but leave
HDMI plugged in). Turn on and system powers up normally. Once to the
login screen, I plug in USB and keyboard/mouse works and I log in.
What might be causing poweron to hang like this?
A bit of a nuance. Once I get this system set up, cold power ups
might be once a month. Though I wonder what it will do coming out of
sleep when I close the unit. Something else to see.
But weird or what?
thanks
