[Solved] Laptop ACPI and Fan problems

My laptop is a Dell Inspiron e1705 with a Nvidia 7900GS. I've got Arch running fine with a custom kernel and Gnome. I'm just having some problems with the ACPI and fans.

ACPI:
Well, I think it's ACPI... Anyway, suspend works find if I do "sudo pm-suspend" in a terminal somewhere. The problem is when I open the laptop lid, it comes out of standby and there is no password prompt. Is there some way to make it wake up only when I press the power button? I've had it randomly be on a couple times while it was locked up in my backpack and it gets crazy hot in there if it's on.

I think this is more of a Gnome/permission problem, but, if I hit the standby button it doesn't do anything, and when it goes to standby after an hour it says something about it not being able to.

Fans:
They just don't run unless it gets really really hot, then it only runs on low. I've tried doing this from the wiki, but nothing shows in it except for

##It's not hot right now since I'm using it in a very cold building.
acpitz-virtual-0
Adapter: Virtual device
temp1:       +45.5\u00b0C  (crit = +126.0\u00b0C)

I have the fan module in, but /proc/acpi/fan is empty and there doesn't seem to be anything helpful in /proc/acpi/thermal_zone/THM/ either (not sure if there's supposed to be, I'm fairly new at this).

If I can get these fixed I can probably erase my Windows partition, but I can't have it burning up my laptop

Thanks in advance for any help.

Command pm-hibernate should work the way you want.

Sorry for the long delay, a lot of school stuff has come up.

I have my fans working right now. I forgot to build the i8k module for fan control.

I still don't have it where it won't come out of standby when the lid is opened.
The pm-suspend command works, but only for root, even though I'm in the "power" group. I can't get Gnome to show a "Sleep" button in it's shutdown menu either. I thought it used to show one (I know it did when I ran Ubuntu around version 6.1 or something).

@sage

check the BIOS of the laptop it *might* be configurable ther.

Also, check /proc/acpi/wakeup ... AFAIK "echo LID >  /proc/acpi/wakeup" toggles the LID behaviour .. let me check ... on my laptop I run this script to make sure it's disabled on every suspend-to-ram:

grep -q 'LID.*enabled' /proc/acpi/wakeup && echo LID > /proc/acpi/wakeup

Thanks damjan. It works great now.

Also the "Suspend" and "Hibernate" buttons randomly showed up on Gnome shutdown menu like they were supposed to be.
