Firmware == bios?

None that I know of ... But the system does kind of suspend
(hdd is spun down, monitor shuts down, ....) but when the system
resumes (press key, move mouse) the temperature of the cpu is
still the same it was before the suspend. Sometime ago the
cpu cooled down to roomtemperature (sys temp also). But this
does not happen any more :-(

When I press the suspend button the message appears
almost instantly (message appears several times). But
I checked 2.4.18-pre7 and there the message does not
appear but the cpu does not cool down either. The kernel
that generates this message was 2.4.17-rmap12a.

That is exactly what I would like it to do and which it
partly does. But the cpu does not cool down (it seems as
if it is not shut down - do I have to use a config option
for this?).

CONFIG_PM=y
# CONFIG_ACPI is not set
CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
CONFIG_APM_DO_ENABLE=y
CONFIG_APM_CPU_IDLE=y
# CONFIG_APM_DISPLAY_BLANK is not set
CONFIG_APM_RTC_IS_GMT=y
# CONFIG_APM_ALLOW_INTS is not set
# CONFIG_APM_REAL_MODE_POWER_OFF is not set

Do I have to enable one of these?

Regards,

Well, yeah ... I suppose there's no point in getting greedy, is there?
