Acpi, slackware, and thinkpad t40


I recently bought IBM Thinpad T40, and put Slackware 9.1 on it. I also compiled 2.6.0 kernel. Now I think more or less the acpi should be working but the directory /proc/acpi has nothing useful inside. There is no battery status or fan status. Was anyone successful in getting the acpi to work on a similar setup to mine? What effect does the acpi has on the battery, is the battery's life shortened without acpi?

Hi Pioter

First question: Make sure you activated all the stuff under ACPI: battery, fan, thermal and so on...if you compiled it as a module, you have to insert them using modprobe.
Second question: ACPI is not really responsable for saving energy (although you can enter some sleep modes with acpi. See kernel documentation->look for /proc/acpi/sleep). This is done using a userspace daemon like cpufreq or autodyn (or similar...;-))

Yeah, I compiled all the stuff I was missing as modules ;-) So the acpi works, sleep also works, but how can I get that little light to light up when the laptop is in sleep mode?
