I own the same machine and made some of the ACPI features work quite nicely. But this does not apply to any of the suspend modes. Not sure if this is even supposed to work, yet. At least for the stable kernel series. I'd like to see this feature, too, especially suspend to RAM. You could try the swsusp patch, but this is completely unrelated to ACPI. I tried that patch once and it seemed to work for me. > APM: > cat /proc/apm tells me -1% for the battery status with the kernels > 2.4.19, 2.4.20, 2.5.59.

Tried APM only for a short time and experienced the same problems. > ACPI: > The following holds for kernel versions 2.4.19, 2.4.20 (patched with > latest acpi patch) and 2.5.59 > - /proc/acpi exists > - however there is not /proc/acpi/battery entry > - echo 1 > /proc/acpi/sleep does nothing > - cat /proc/acpi/sleep tells S0 S3 S4 S5 > - drivers battery, button, processor etc are loaded when I lsmod > - dmesg tells me that acpi is turned on By using a tweaked DSDT you can make almost all of these features work except the suspend mode. This includes the values for batteries and thermal zones, as well as all the buttons (power, sleep, lid). Unfortunatly none of them work out of the box. Tell me which BIOS version you're using and I might email you my modified DSDT including some instructions on how to make the kernel recognize the new DSDT.
