I have a user with an Acer ES1-522 laptop and the wifi isn't working.
The driver detects it correctly, but rfkill says it's hard blocked. The
wifi toggle key doesn't have any effect. The touchpad toggle button
disables the touchpad, but doesn't enable it when pressed again.
However, suspend/resume resets the touchpad to working again. The
acer-wmi module is loaded and an input device is created. However, none
of the listed keys actually provide any output.
I blacklisted the acer_wmi module and now the wifi works. Is there any
further information I could provide that would help?

Possibly related, the accelerometer gives an error when trying to read it.
