A note: this page

... claims that there is wakeup bug in ACPI for Haswell machines from
vendor HP. That bug could be the same as this, given that this macbook
11,1 also has a Haswell chipset.
And out of the blue I received an email from someone reading this bug
thread suggesting a potential solution to this issue.
Verbatim:
#####
I googled around and found a solution which worked for me:
echo XHC1 >/proc/acpi/wakeup
To verify the change just type:
cat /proc/acpi/wakeup
And now this machine sleeps until the lid is opened!
You may also need to disable the wakeup of usb devices like this:
for usb in /sys/bus/usb/devices/*/power/wakeup;
do
echo disabled > $usb;
done
#####
I have not tried it yet as I would like to learn more about /proc/acpi/wakeup
So far I haven't found the manual page yet.
