NOT wake on lid switch?

[dotancohen]

How can I configure a Debian-based distro (Kubuntu) not to wake when
the lid switch is activated? The laptop in question is a Dell Inspiron
E1505 / 6400.

The wonderful engineers at Dell used a plastic so thin that when
pressure is placed on the lid when closed, it trips the switch. I have
found the machine idling with no airflow in my bag several times
already.

Thanks in advance.

Thanks. I looked at the script, this is what is in it:

# /etc/acpi/events/lidbtn
# Called when the user closes or opens the lid
event=button[ /]lid
action=/etc/acpi/lid.sh

The /etc/acpi/lid.sh script is far above my skill level. Could I
simply replace /etc/acpi/events/lidbtn with a blank file, thereby
preventing the laptop from do anything when it runs? Alternatively, I
thought about simply disconnecting the switch from the motherboard (I
have already disassembled this lappy two or three times).

Hi,

  IMHO tweaking the hardware for a solution which can be achieved
   by software would not be a good idea.

   The script /etc/acpi/lid.sh does 2 tasks
   a) to send the system to suspend when the lid is closed
   b) to get the system back to normal when the lid is opened.

   In case you want to disable the lid action then just comment the line

  action=/etc/acpi/lid.sh
in the /etc/acpi/events/lidbtn script

(comment by adding an # in the start of that line as like below)
  # action=/etc/acpi/lid.sh


that will disable the lid switch activity all-together.

if i understand your question correct, none of the answers given, will
help you, because you want to _disable_ the wakeup and not edit the
events _after_ wakeup.

on my systems there is in the proc directory a file called:
    /proc/acpi/wakeup
which shows which devices will wakeup the laptop is suspend.

and i don't have much documentation .. but for my thinkpad there is this
article which should work on every laptop with sane acpi.

http://www.thinkwiki.org/wiki/Talk:How_to_make_ACPI_work#Auto-wake_on_lid_open_-_how_to_STOP.3F

---------------- cut ----------------
There is a /proc/acpi/wakeup file here. (t42p). Currently shows: Device Sleep state Status

> cat /proc/acpi/wakeup
  LID       3            * enabled
SLPB       3            * enabled
PCI0       3            disabled
UART       3            disabled
PCI1       4            disabled
USB0       3            disabled
USB1       3            disabled
AC9M       4            disabled

and ..
echo " LID" > /proc/acpi/wakeup
should disable the LID from waking up
---------------- cut ----------------

but on the site are some comments.. so reading is reommended.

Thank you Bhasker. Commenting out the line in question did in fact
prevent the laptop from going into standby when I _close_ the lid.
However, the machine still wakes from standby when I _open_ the lid.
So this is not a solution to my problem.

I looked in the BIOS thinking that there may be an ACPI disable option
there, but there is none.

did it have MS-W preinstalled? still there & bootable on a partition?

if yes to above point, does this happens in MS-W as well? perhaps the
full knobs to wakeup and such are in a MS-W -only util - if not from BIOS,
there should be a user control to (un)set wakeup events.
There are specific acpi kernel modules for Dell and a handful other vendors
to tweak this stuff from Linux, try and see if you get success in loading
such module and if something new appears in /proc/acpi (or /sys if the
/proc interface is disabled in your kernel).

Thanks, I will start googling Dell-specific settings.

Or, maybe not. I will simply disconnect the switch. I don't want to
fiddle with it each time I upgrade my distro (every six months on
average). That's what I usually do with the pc speaker on desktop
systems anyway, as each distro wants me to blacklist the module in
it's own unique way :)
