Opening Laptop Lid does not wake from suspend anymore

I have an ASUS Zenbook UX435E (Works very well on Linux so far [except this]).

When I initially installed arch the laptop would suspend after closing the lid and resume after opening, as expected.

The Wiki page for similar Zenbook laptops https://wiki.archlinux.org/title/ASUS_Z … 33#Suspend recommends adding

    mem_sleep_default=deep

for a more power efficient sleep.

After making this change (and rebooting), the laptop no longer wakes from sleep after opening the lid. Any key press will wake the laptop, but the lid will not.

Checking the state of the lid through the terminal shows the correct state

    cat /proc/acpi/button/lid/LID/state

What steps can I take to fix this and wake my laptop by opening the lid again?
