 |
|
Ok, I managed to get ACPI and speedstep working and I emerged acpid to control any events and I used friday his scripting talent to help me. Thing is, acpid NEVER EVER does something with the events. I don't think there's an event created at all in /proc/acpi/event... Every module is working correctly. When I cat the event file and try to push the power button or plug in/out the power adapter, nothing changes that file... Is this normal?
Dmesg | grep ACPI gives:
| Code: | ACPI: RSDP (v000 DELL ) @ 0x000fdea0
ACPI: RSDT (v001 DELL CPi R 0x27d30c0a ASL 0x00000061) @ 0x1fff0000

So I guess it's ok... (Dell laptop here)
The /var/log/acpid file only contains:
| Code: | [Thu Mar 18 16:38:22 2004] starting up
[Thu Mar 18 16:38:22 2004] 1 rule loaded
[Thu Mar 18 17:49:15 2004] exiting
[Thu Mar 18 17:49:57 2004] starting up
[Thu Mar 18 17:49:57 2004] 1 rule loaded |
But really doesn't do anything else... 
Anyone?

Second problem
I noticed in windows, when I set my speedstep to the lowest frequency my CPU temprature stays around +/- 40° C. When In linux AND i'm on the lowest frequency, my CPU temprature stays around +/- 52° C !! When my processor is around a minute or 2 active He's too heat and my fan starts blowing faster but that's quite annoying since I'm not doing any heavy-cpu-usage (like browsing, results in heavy tempratures! that ain't normal...)
How can I reduce that temprature? Speedstep does not help it seems... ACPI is enabled but I don't really know how to configure it (is that needed?) This results in linux my battery life is around 2 hours with "low" cpu usage. In windows, it's about 3,4 hours!!!! I really like to keep it that way too in linux... help? |

Ok, I ran my laptop for a while using hdparm to spin down my HDD and using "xset dpms force standby" to turn off my monitor. I think it was about an hour or so, time enough to give my CPU temprature time to cool down.
Initial (Start) Temprature: 52° C.
Finally (Stop) Temprature: 50° C.
That is not normal anymore!  I speedstepped to the LOWEST frequency, disconnected my power, turned off monitor AND turned off my HDD and it only gives 2 ° difference? C'mon! In windows, when In standby mode, I get +/- 33° !!! Could someone PLEASE give me a hand this is really getting out of hand it's not normal for a laptop! Thanks... |

I could REALLY use some help!!
I tried patching my kernel with various ACPI patches but none did work. Even the DSDT in ACPI with the intel compiler decompiled, solved 1 warning and recompiled but still no go... |

| Code: | loz@thinkloz loz $ acpi -V
Battery 1: charging, 97%, 00:05:45 until charged
Thermal 1: ok, 54.0 degrees C
Thermal 2: ok, 44.0 degrees C
AC Adapter 1: on-line
loz@thinkloz loz $ |
I wouldn't worry too much about it. AFAIK, ACPI in linux is still a young project. Whereas ACPI drivers for windows are much more developed and thus will yield better performance.
