[ACPI] ACPI on Compaq Evo N800c

[Christian N. <ne...@ii...>]

Dear ACPI developers,

I have a Compaq N800c Laptop and need a way get the machine to standby, 
when closing the lid. I already tried:

APM:
cat /proc/apm tells me -1% for the battery status with the kernels 
2.4.19, 2.4.20, 2.5.59. ACPI was not compiled in. apm -s returns 
immediatelly without putting the machine to sleep.

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

I use the latest BIOS patch for this machine. I dont knwo what to do 
next. I have seen similar posts for this machine on the net. Is anybody 
out there that help me or has a patch for that problem?

Regards
Christian
