Comment 26 for bug 59867

I can confirm that the same problem exists with my Averatc 5110H laptop. Interestingly, if I turn of ACPI and use APM to suspend-to-ram, it comes back with a working touchpad, but battery and fan monitoring/control are absent.

I also should note that my laptop has a software controlled RF switch; to turn on the wireless radio requires a special kernel module (av5100). Is it possible that the laptops experiencing this problem require some software to turn them back on? Apparently, it would seem as though the Bios (acpi) is disabling the touchpad purposely. Otherwise, if it is a linux kernel issue, why aren't all laptops affected?

Finally, you should know that Pedro's issue seems to be different. On my laptop, and most on this bug, /dev/input/event* are not just changed for the touchpad, they are completely gone.

Normally, I have the attached under /proc/bus/input/devices. That is gone after resuming from suspend-to-ram.
