 |
|
Hi There!
I have a notebook which is quite unsupported by the app-laptop branch of portage ; )
It's a Maxdata M-Book 1200x with an AMD Mobile 2600+ Processor.
Now it was rather cheap and the battery is not that goot... it lasts only about 70 min...
Basically I followed the Gentoo Power Management Guide.
I didn't get the CPUFreq drivers working, but it doesn't matter too much anyway.
What i need:
* Suspend (mem or disk - one at least : )
To the acpi suspend stuff:
| Quote: | | echo 1 > /proc/acpi/sleep |
or | Quote: | | echo -n standby > /sys/power/state |
the screen turns dark, after one or two seconds it returns to normal mode again 
| Quote: | | echo 3 > /proc/acpi/sleep |
or | Quote: | | echo -n mem > /sys/power/state |
I get a short message like "Saving Data => MEM" or so and everything turns down (inc. cpu + fan).
But I cannot recover the systen with any of the buttons...
what can i do to get at least some power saving working?
should i go for APM?
any infos are very welcome!

Have you tried to close the lid and open it up again? This is an acpi event too, although I can also fire up the FN button to start up again.
Check also the acpid event log to map events to functionalities. The logfile is in /var/log/acpid.

Try to add acpi_sleep=s3_bios to your kernel options in lilo or grub. You must also have X started. Once it helped me. |

Are you using a recent kernel? Can you try the hibernate-script instead of writing to files in /proc or /sys? There's a more detailed description in the updated power management guide.
