[ltp] T43: closing stops the machine under ubuntu

[Helmut Hullen]

Hallo,

I'm running some Thinkpads (T2x, T4x). Some of them work as a kind of  
server (unattended, closed, no energy saving).

Under T2x (and especially under Windows) I can close the display and the  
machine runs without any problem.

Now I'm playing on a T43 with Ubuntu 9.10 and Kernel 2.6.39.1 (self  
made, based on SuSE kernel 2.6.37.6 config)

        cat /proc/acpi/wakeup

tells "LID *enabled"

When I close the machine then it goes to sleep - it stops the hard disk,  
it cuts the network connection etc.

Wakening is awfully: I have to go to the machine, open it, push some  
keys, type my password etc.

        echo LID > /proc/acpi/wakeup

changes the contents to "disabled" but seems to change nothing else.

What can I do, what should I do?

Viele Gruesse!
Helmut
