Resume doesn't work as intended when closing the laptop lid

[Erik Andrén]

Binary package hint: acpi-support

Hardware: Asus 1005HA Netbook, Karmic Koala

Problem: When suspending the machine by closing the laptop lid the machine doesn't wake upon lid opening. Instead you need to push the power button. When the button is pressed the netbook comes back alive again for a couple of seconds but then resuspends itself. When you press the button once more the machine resumes normal behaviour.

If you initiate the suspend by pressing the power button or select it via System > Shut down, the machine resumes itself correctly on the first try.

Also, when experimenting with acpi_listen only the suspend lid event is detected.

No resume event is detected when opening the lid in windows 7 either, i. e. you must press the power button. This is probably due to how the micro controller is programmed.

Also, this problem only exhibit itself when running on battery with no AC adapter connected.

As you say, if the system does not resume on lid open, this is a problem with the machine's ACPI implementation; there is probably nothing that Ubuntu can do to work around this. You should consult your hardware vendor for information about the availability of a BIOS fix.

No, this is a regression from jaunty.

I've just tested the same operation using a livecd where it works flawlessly.

[Erik Andrén (erik-andren)]

Jaunty livecd that is.

To further clarify the issue:
It's _not_ that the laptop doesn't wake up on lid opening, but that once the power button is pressed, the system suspends once more, requiring one extra power button press to regain normal behavior.
