[ltp] Power drain with ACPI

[Yip Wai Peng]

Hi all,

I'm currently using a T41 with ibm-acpi and acpi compiled into kernel. 
Whenever I do a suspend to ram, I've noticed that although it has been 
suspended, it still drains about 20% power per hour. The laptop is also 
constantly warm, as if some device is not fully shut-down. (I know ram is 
still powered but that shouldn't produce that much heat right?

I am wondering if anybody has the same problem? Also, is the anyway to check 
whether which device have not been suspended? 

/etc/acpi/actions/sleep.sh: 

#!/bin/bash

/etc/init.d/cpufreqd stop
modprobe -r uhci_hcd
modprobe -r ehci_hcd

echo -n mem > /sys/power/state

#/etc/acpi/actions/battery.sh
modprobe uhci_hcd
modprobe ehci_hcd
/etc/init.d/cpufreqd start
