Notebook temperature issues and need help in disabling suspend/sleep mode

Hello all:

I have a IBM ThinkPad 770Z notebook running the latest -current and I'm 
having a few issues.   The first one is, is there a way to disable 
sleep/suspend when the lcd lid is closed since I only want the lcd display 
to be off but the machine still running normally.  The second issue is the 
cpu fan doesn't seem to turn on even after I issued the following commands 
in /etc/rc.local as per one of the message threads on the list:

/sbin/sysctl -w hw.acpi.thermal.tz0.active=1
/sbin/sysctl -w hw.acpi.thermal.tz1.active=1
/sbin/sysctl -w hw.acpi.thermal.tz2.active=1
/sbin/sysctl -w hw.acpi.thermal.tz3.active=1
/sbin/sysctl -w hw.acpi.thermal.tz4.active=1
/sbin/sysctl -w hw.acpi.thermal.tz5.active=1
/sbin/sysctl -w hw.acpi.thermal.tz6.active=1

This is the message on the console I get a few minutes before the system 
shuts off by itself without syncing the disk.
