Wake on WLAN

I have two very similar Lenovo computers M900Q and M910Q.
I can make the M900Q wake from suspend by sending it a WiFI magic packet but this doesn’t work with the M910Q.

I thought it might be due to the WiFI board but I swapped them with no effect. The BIOS settings are identical.

If I ‘freeze’ instead of ‘suspend’ I can wake up the computer with the magic packet.

Does anyone know how I can debug this further?
