[ThinkPad X1 Carbon] System wakes from suspend almost immediately if USB keyboard is plugged in

[prathamesh]

Suspend mode does not seems to work. Clicking on suspend button sends laptop in suspend mode and in few seconds laptop comes out of suspend mode and shows login screen again.

Thanks for the bug report.

Please try disabling Bluetooth AND unplugging your USB keyboard before suspending. Does that avoid the bug?

As per your suggestion i unplugged usb keyboard before suspending. Everytime it works if i unplugged usb keyboard. It looks like this is something usb keyboard specific issue. Is there any permanent solution on this or i have to unplugged usb keyboard everytime.

[Daniel van Vugt (vanvugt)]

You can tell the kernel to ignore particular devices that might wake the machine up by:

  sudo sh -c 'echo NAME > /proc/acpi/wakeup'

That will just toggle device NAME between enabled (can wake up) or disabled (can't wake up). But the hard part is figuring out which device name from /proc/acpi/wakeup is relevant to the USB keyboard. Maybe 'XHC' representing the USB controller?

Your BIOS might also have settings to control which devices can wake the machine up.

i plugged in usb keyboard in different port. Now there is no issue in putting laptop on sleep mode.
